How To Troubleshoot Your Furnace Before Calling A Houston Heater Company

Troubleshooting Your Furnace: 4 Quick Fixes To Try Before You Call A Professional AC Man In Houston

Would you want to spend $100 and then be told the obvious? You wouldn’t?

We didn’t think so. However, that is what frequently occurs when homeowners in Houston call us about furnace repair. The “problem” is often caused by a minor problem that could have been repaired, which could save themselves the expense of a service call.

If your furnace is not working the way that it should be, wait on the service call. First, try out the following 4 simple troubleshooting tasks. If they do not fix the problem, then call us for assistance.

1. Check The Thermostat For Problems

Is your furnace not turning on? First, check your thermostat and then do the following tasks:

  • Make sure that your thermostat is set on “heat” and not on “cool”
  • Also, be sure the thermostat is turned 5 degrees higher at least than the room temperature is.
  • Replace the battery on the thermostat
  • Open up the thermostat and blow out any accumulated dirt or dust. If your furnace is sometimes blowing cool air, you should check your thermostat fan setting in order to be sure it is on “auto” and not “on.” A furnace’s “on” setting” causes the blower to run continuously even when the air is not being heated by the furnace.

2. Check Your Furnace Filter

Is the furnace randomly shutting down? Does it run for long periods of time and seem to not heat your house? Is it weak air coming out of the vents? If so, then the furnace filter may be dirty.

When your system has a dirty furnace filter it restricts the airflow over the heat exchanger over the furnace, which can cause a number of different problems:

  • The heat exchanger overheats and then shuts down.
  • Soot may accumulate on the heat exchanger, which reduces the efficiency of your furnace. This reduces airflow that comes out of the vents. Which means that the furnace is operating, but you are never comfortable.

The owner’s manual for your furnace should show where the filter is and direction on how to replace it. Your filter should be checked once a month at least and then change it, as necessary. So when is a filter considered to be “too dirty” for you to keep? Hold your filter up to a light. If you are unable to clearly see any light coming through, then replace the filter.

3. Check The Shutoff Switches & Circuit Breakers

Is your furnace refusing to turn on no matter what the temperature has been set to? It might be turned on. The following are a couple of places to check:

  • Standard wall switch close to the furnace. It may look like a regular light switch.
  • Circuit breaker panel. Search for the switch that has a furnace label close to it. When the switch is in the center position, that means it is tripped. Turn the switch to “off” and then “on.” If that results in the circuit breaker tripping again, then you have another problem that needs to be fixed (such as having to replace the air filter.)
  • The front panel that covers the blower. Be sure the panel is shut closed all of the way. Under the panel is a switch that must be depressed in order for your furnace to work.

4. Open Up Any Air Vents That Are Closed

Homeowners frequently close the air vents in the rooms they are not using in order to save money.

However, when vents are closed in any room it actually causes the opposite to occur: it actually wastes money – and may also cause your furnace to shut off.

How?

The size of your furnace is designed for heating up your whole house, including unused rooms. Closing vents will not reduce how much air is pushed out by the blower. It only increases the pressure inside the air duct system.

(Picture yourself attempting to run while breathing with just one nostril. You are still attempting to move around the same amount of air, but there is a lot more pressure that travels through only one nostril.)

The added pressure within the duct system can cause several of the problems that you might be experiencing:

Less comfortable – A majority of houses have air duct leaks, that allows for the escape of conditioned air. Extra air pressure inside of the ducts pushes out more air through the leaks – or creates even more air leaks. This means that less air is getting into certain parts of your house.

Furnace continues to shut down – The added pressure causes your blower to work at lower speeds. That decreases the air over your heat exchanger, which cause it to overheat and then shut down. That is like you have a dirty air filter.

Should You Repair Or Replace That Old Furnace?

Use These 3 Factors To Decide Whether You Should Replace Or Repair Your Gas Furnace

It’s sad to hear that your furnace is no longer working as it should.

The hard part howev, however,ves making a choice between spending your money on repairs or a new replacement.

Keep the three essential factors listed below in mind when making this decision.

1. How Long Has The Furnace Been In Use?

If your furnace doesn’t have a long life ahead, you don’t want to be spending too much money on repairs. Before you decide, make a comparison between its average lifespan and its current age.

According to the National Association of Home Builders, the average lifespan of furnaces is estimated to be somewhere between 15 and 20 years.

If you don’t know how old your furnace is, use the following tips:

  • Inspect the unit for a year of installation. This information is written on furnaces by some installation technicians.
  • You need to switch off the furnace and give it some time to cool down before you conduct the inspection. Check for a metallic identification plate, normally on the chamber door of the furnace. Copy the serial and model numbers there. To get a specific date on when the furnace was manufactured, contact the manufacturer using their customer service number.
  • You don’t have to replace the furnace if you find out that it was made more than 20 years ago. With proper maintenance many, furnaces deliver reliable performance long after the 15 to 20-year useful life.

2. Replacement versus Repair Costs

Make a comparison of these two costs while considering the age of your furnace:

  • Furnace repair cost.
  • Furnace replacement cost.

Remember the following to ensure that you arrive at the correct repair cost, Seek numerous quotes.

To find out if you can save on repair costs by paying for labor and getting parts for free, remember to find out what the warranty covers and whether it is still has some time before it expires.

Replacement costs are determined by:

  • Your preferred furnace size
  • Your desired Annual Fuel Utilization Efficiency level
  • Single or two-stage and type of blower
  • You might have to spend anything between 1,100 and 6,000 dollars on a new replacement.

As a rule of thumb, if the repair cost of your furnace is a third, or more, of the replacement cost and it has already been in use for two thirds, or more, of its useful life, you should seriously consider having it replaced.

For instance, it is better to replace your furnace, in the long term, if it has been in use for 15 years or more and requires an 800 dollar repair cost, versus a 2,400 dollar replacement cost.

3. Your Current Situation

The most important factor to consider is your current situation. Some situations and issues may relate to you:

  • Your available budget: Your budget, at present, may not allow you to spend big on a new furnace, making repairs your only option. However, if you really need a replacement but can’t afford it, consider seeking financing.
  • Huge energy Bills: If you are looking to start making savings on your energy bills, consider getting a replacement. Depending on the energy efficiency of the new furnace you stand to make savings ranging between 10 and 25 percent off your energy bills.
  • Your Expectations: You might be better off having your furnace replaced if you it always struggles to meet your expectations.
  • Frequency of Repairs: It is best that you replace an old furnace that is always in need of some sort of repairs, regardless of how much they cost.

HVAC Repair Specialists Troubleshoot Your Finicky Furnace

Furnace Blowing Cold Air: A Homeowner’s Troubleshooting Guide

Homeowners live in a huge range of climates, and every house is different. Turning on your furnace universal, though. No matter who you are or where you are, the last result you want is a blast of cold air.

What could be behind this sort of mechanical betrayal? Lots of things! There are many issues that can push down the temperature of the air your furnace emits, and some of them can be easily solved without professional assistance.

Before you get on the phone to your preferred HVAC experts, here are four solid pieces of furnace troubleshooting advice:

Check The FAN Setting On Your Thermostat

If your heating system seems to alternate between hot and cold air, the culprit might be a blower fan running full time.

Check your thermostat’s fan setting. If it’s turned to “ON,” your heating system’s blower will be running around the clock, whether or not your furnace is actually warming up the air in the system. This can easily produce chilly air currents at unwanted times.

To solve this problem, simply set the fan to “AUTO” on your thermostat. This will link the blower to the furnace so that it only pushes out air when the furnace is running.

Check The Air Filter Of Your Furnace

An old, dirty, clogged-up filter can cause your furnace to blow cold air.

This happens because your furnace relies on a steady flow of air over its heat exchanger. If that airflow is impeded by a clogged filter, an automatic filter may be shutting your burners off to prevent damage. Allowing the heat exchanger to get too hot could cause it to crack.

To fix this problem, check the furnace filter and replace it if it’s dirty. You’ll need to shut your furnace down (at the thermostat) first. Note that resetting the furnace may require professional assistance.

Check Your Pilot Light

In older-model furnaces, the burners need a standing pilot light to switch on. If the pilot light has been extinguished, the heating system won’t function.

You can relight your pilot with this simple procedure:

  1. Turn your furnace off.
    Switch your thermostat to the “OFF” position.
  2. Locate the plot light and reset switch.
    These pieces of equipment are usually at the bottom of the furnace. If you’re having trouble finding them, check your manual. The furnace reset switch is typically behind an access cover you’ll need to open. The switch will have three settings: PILOT, OFF, and ON.
  3. Set the reset switch to “OFF” and wait 5 minutes.
    This step shuts off the gas flow. You need to wait to let any remaining gas dissipate.
  4. Set the switch to “PILOT” and press it down.
    This restarts the gas flor to the pilot light.
  5. While holding the switch down, hold a lighter at the pilot opening.
    When the gas catches and the flame lights, you should see a steady blue flame. If it’s working properly, it should hit the furnace’s thermocouple (a small copper bar) right in the middle.
  6. Set the switch to “ON.”
    This will allow your furnace to function properly.
  7. Turn your furnace back on at your thermostat.
    Set the thermostat to “HEAT” again. Start with the temperature setting 5 degrees below your normal room temperature and check for hot air.

If Your Pilot Light Won’t Light Or Hold A Flame

If the pilot light isn’t functioning properly, you need professional help. The problem may be a broken thermocouple (which is a cheap, fast repair) or something more serious.

Check Your Condensate Line

If your home has a more modern, high-efficiency furnace, you may have a condensate line blockage. The blocked line will cause your furnace to shut down automatically. The telltale sign of a blockage is puddled water around the furnace.

High-efficiency furnaces produce water (the condensate) while they’re running. This has to drain out of the furnace, typically through a PVC pipe. If water can’t leave, it will trigger a kill switch and shut down the furnace so that the water can’t damage it.

Condensate lines can be blocked by dust, dirt, mold, or (if the line runs through an uninsulated area) ice. Your furnace may also suffer condensate overflow if its condensate pump breaks down. This is another problem that requires a professional fix.

You can use this in-depth Energy Vanguard tutorial to help you unclog a condensate line. If your line is being clogged with ice, use pipe insulation and heat tape to wrap it where it runs through unconditioned spaces.

Furnace Being Indecisive? AC Man Of Houston Can Help!

What Causes A Furnace To Turn Off And On Frequently

Short cycling is when a furnace stops and starts more often than it should. Your furnace can suffer a lot of damage if it’s short cycling. Not only that, but your utility bills can increase.

What Causes Short Cycling

Overheating can cause it. So can issues with the thermostat. Also, an over-sized furnace could be the reason. We’ll go into these in more depth and how you can take care of them.

Overheating

If your furnace is shutting down, then the exchanger could be the culprit. The furnace shuts itself down when the exchanger overheats. This is to protect it from cracking.

Eventually, the heat exchanger can crack. It is very expensive to replace an exchanger, and it is sometimes better to replace your entire furnace than replacing the exchanger. Unless you have a parts warranty, then you’ll want to consider replacing the furnace.

What Causes Overheating

A dirty air filter can cause the heat exchanger to overheat. What you should do is check the air filter 1-2 times per month. Make sure to change it if it looks dirty.

Blocked Off Air Vents

An exchanger can overheat if air vents are blocked off. When you close the vents or if they are blocked off, then the air ducts are subjected to more pressure and this can lead the blower not blowing out as much air as it should. When the airflow is low, then less heat is exchanged and this can lead to more heat to build up. If you want to fix this problem, then keep the vents open and do not block them.

Blocked Exhaust Vents

Certain gases gave to be exhausted, which your furnace does via its exhaust vents. However, there are a number of things that can block these vents, and this includes leaves, nests, and debris. This can lead to furnace overheating, which is dangerous. Furthermore, carbon monoxide could end up being released into your home.

Do you know where your furnace’s flue pipe is? If so, then inspect it to make sure nothing is clogging it up. Be careful if the vent is located on the roof.

Thermostat Issues

Thermostats let your furnace know when to turn on and when to turn off. If short cycling is happening, then the thermostat might be faulty. There are two common issues that affect thermostats, and this includes:

  1. Malfunctioning- A thermostat that malfunctions need to be replaced. It might be able to be repaired. A professional can help you out here.
  2. Improper Placement- The thermostat might be tricked into thinking your home is warm enough. This can happen if it’s installed near a heat register, direct sunlight, the kitchen or other heat sources. This is why you want to make sure the thermostat is installed in a proper place.

Oversized Furnace

Did you install a new furnace recently? If so, it might be too big. A furnace that’s too large can heat your home up very fast, but this can actually cause your energy bills to skyrocket.

What you need to do is contact the professional who installed your furnace. Tell them what the problem is. They should be able to correct the problem, such as reinstalling a furnace that is a suitable size for your home or they will offer another solution.

What Sort Of Questions Should You Be Asking Your Houston HVAC Repair Company

HVAC Questions That You Should Ask Your Service Provider (And The Answers You Should Get) Part 1

Do you trust that your contractor will answer the HVAC questions that you have honestly? When you are looking for an HVAC service provider to repair broken equipment, do preventative maintenance or install your new unit, we know you will have some questions that you need answers to. Over our many years in business, we have been able to figure out the top HVAC questions that people are wondering about but are not comfortable to ask. That might be due to the fact that you don’t think you will get an honest answer from a service provider who only wants to sell services to you.

So today we will be giving you honest answers to some of the toughest HVAC questions that people ask. AC Man of Houston is the Houston metro area’s biggest HVAC service provider. We have been providing these services for over 60 years. Therefore, we have plenty of information about everything we are telling you. So go ahead, ask your HVAC company these questions and find out if they give you the same answers that we are giving you today.

Reliable answers to the main 5 HVAC questions

1. How long is my new air conditioner expected to last?

A majority of light commercial systems have been built to last for approximately 15 to 20 years. However, there are various conditions that may shorten their life expectancy. When rooftop and outdoor units get exposed to salt air and smog, since they are in Houston, build-up and corrosion of debris may damage the parts. This is also true when it comes to corrosive chemical exposure as frequently occurs in manufacturing plants.

Probably the most common thing that causes the early demise of an air conditioner is neglect. Your system needs to be cleaned and maintained on a regular basis to get the maximum life expectancy from them. that means twice per year at least (once before starting it up in the spring and then again in the fall when the system is shut down), you will need to have a certified HVAC professional to come out and tune up and thoroughly clean your air conditioner. Having an annual maintenance contract means you will receive the best price and get reminders.

2. Does it really pay off to spend money on maintenance on a regular basis?

As previously discussed, AC Man of Houston repairs and maintains thousands of HVAC systems each year (sometimes during the busy season it is every month) so our answer is based on our extensive experience. I promise that our customers who have a preventative maintenance contract, with well cared for equipment, experience few costly repairs and breakdowns compared to those who neglect replacing worn parts, tune-ups, and cleaning. Preventative maintenance not only helps you save money on repairs but also helps your equipment to last for a longer period of time.

It can also help save money on your energy bills also. When deposits and debris build up in your air conditioner’s fan blades, coils, and other parts, it results in the metal corroding, which can lead to refrigerant leaks and finally system failure. This results in a drain on your system, which forces it to constantly run to keep the area cool and to use more electricity during the process. If you clean the unit on a regular basis it will help to ensure that it runs at its optimal efficiency and will keep its parts in good condition in order to last longer.

3. Can Your Maintenance Staff Do HVAC Cleaning?

There are some cases where this is possible. If you have an air conditioner that has a heavy load, your cleaning crew could be able to dust the soils and remove debris from around the unit. However, you need to ensure that they do not use any liquids around the electrical components.

While this is possible, you will still need to have the system cleaned by a professional twice a year. Professionals have special chemical cleaners that will remove any scale and other buildup from the coils. They are also able to clean parts of the system that would be dangerous for the maintenance staff to work with including the fan blade.

Drain lines will also be kept clear by a professional cleaning and drip pants will be emptied to prevent mold. If you work with a certified HVAC technician, they will be able to check the electrical connections and refrigerant while inspecting the whole system for any wear. Potential signs of trouble will also be picked up by a professional and these are all tasks that you do not want to leave to the maintenance team.

4. Your Air Conditioning Unit Keeps Breaking Down, Should You Repair Or Replace?

There is no simple answer to this and you will need to take a number of factors into account when you make your decision. You need to consider how old the unit is. If it is older than 10 years, it would be better to replace the unit instead of repairing.

The maintenance that has been done on the unit is also important. If the system was regularly maintained, cleaned and serviced, you could probably keep it going for longer. This is particularly true if the parts are still in good condition.

What is broken will also need to be looked at. If you have a problem with the compressor or the coils ate leaking, you should replace because repairing will be expensive. If it is an electrical problem, you should consider repairing because this may be simple and inexpensive.

If your unit is using R22 refrigerant, you should look at replacing it. This refrigerant is being phased out by the EPA and you will need to replace the unit at some point.

5. How Can You Reduce The Expense Of The Air Conditioner In The Summer?

There are a number of ways that you can improve the energy efficiency of your air conditioning system. Some of these ways are easy such as replacing the filters and using a programmable thermostat. You should also ensure that all maintenance is being done including the cleaning of the coils and fan blade. This will keep your system running correctly and reduce energy waste.

You should also look at adjusting the temperature by a few degrees. You might be surprised at the amount that you can save by doing this. This is generally something that you should do when there are fewer people in the building.

Replacing your old system with a new one can also help you save money. A new unit will often use less electricity which enables it to pay for itself through your energy savings. If you know the SEER rating of your current unit, you will be able to calculate how much you can save. If the unit has a SEET rating of 8 to 10, a new unit with a rating of 18 will save you up to 50% on your energy bills.

How Do You Know You Can Trust Your HVAC Service Provider?

Unless you have worked with the provider for a number of years, it can be hard to determine if they are trustworthy. There are some companies that will show you what they are doing during their maintenance visits and this can help you trust them.

Houston HVAC Company Addresses Heat Pump Maintenance & Their FAQ’s

Learn More About How Houston Heat Pump Maintenance Can Benefit You

We’ve been discussing in our blog all month that heat pump technology is rapidly evolving, and heat pumps are picking up in popularity in colder climates. In fact, you may be considering a heat pump yourself, if you’re interested in:

  • Supplementing your existing heat system
  • Replacing your existing combined systems with one combined solution
  • Reduce your carbon footprint and boost your energy efficiency
  • Reduce your regular energy costs and enjoy the heat pump tax credit

However, if combining heating and cooling into one system concerns you, especially when it comes to maintenance, you don’t need to worry.

This week, we’d like to go through the questions that we get asked most often, as well as offer some standard heat pump maintenance tips to help you feel more at ease.

Do heat pumps require service?

Like any other heating or cooling system, your heat pump will benefit from regular preventative maintenance. The difference between a system that is well-maintained and a system that is neglected can range from 10% to 25%, according to energy.gov.

Heat pump maintenance on a routine basis will help ensure that the system performs at its best. It will also help limit damage to the components, including the compressor, making sure that your expensive investment is well protected.

Routine service limits the risk of the heat pump needing unexpected and expensive repairs, as well as helping the system to run more reliably.

What does it cost to maintain a heat pump?

The cost of maintaining a heat pump will vary quite a bit, depending on where you live, how often you have the service performed, the age of your system, and who provides the service.

To understand why the preventative maintenance is worth the ongoing investment, let’s examine the difference between the cost of this important preventative measure and replacing a heat pump after it’s gone bad.

The national average cost for residential heat pump repair ranges from around $350-$1250.

The cost of preventative maintenance on the heat pump averages $170, making this service both cost-effective and a smart option. You can also save on the price of this routine maintenance if you sign a contract for ongoing service with the same HVAC provider.

Can I troubleshoot my heat pump on my own and do my own maintenance?

You should definitely keep an eye on your heat pump for specific issues that commonly develop so that you can prevent future issues.

For example, the defrost cycle will typically run when it is quite cold outside. However, if you notice that the defrost mode keeps coming on, or stays on for more than fifteen minutes, it may be time to call in a professional to evaluate your system.

You can also keep your heat pump running at its best by taking care of routine tasks like dusting around the vents and replacing the air filters.

The reality is that preventative heat pump maintenance is not a job that you can do on your own. If you’re not experienced and trained, it’s very dangerous to work with refrigerant and high voltage electricity. You could wind up doing more harm than good. In these cases, it’s important to turn to a skilled professional for ongoing HVAC maintenance.

How often should the heat pump service be scheduled?

Professional heat pump maintenance should be scheduled at least once per year.

If you use the heat pump for the main heating and cooling system, as opposed to a supplemental system, it may mean that you need to schedule this service twice yearly – once in the spring and once in the fall.

Replace Your Air Filters With Proper Houston HVAC Maintenance

AC Filter Replacing With AC Man Of Houston

Even though it looks like a pointless work, changing your home’s air filter regularly is the alpha of saving money and helping protect your family to stay healthy. However, the million-dollar question is, when should you go for a new filter? Well, below are some factors to consider before making the switch.

Types of Filters

Filters differ from one another in many ways and this is a fact. The difference depends on your air conditioning unit (e.g. Is it located outside or inside). At the same time, expensive filters have been made of quality and durable materials. Furthermore, they apply the latest filtration technology. Therefore, if you purchase a cheaper filter, you will save money, but ion the short-term. HEPA (High-efficiency Particulate Air) filters which are recognized by different Environmental Protection Agencies are the best option. They have been certified to remove at least 99.97% of harmful particles in the air.

Seasonal Factors

Weather can affect the performance of your AC unit. An air conditioner is highly used during warm months (summer) and it is during warm months when pollen and other air pollutants overload the filter. At the same time, moisture causes seals to damage, which leads to leakage of cool air. HVAC professionals advice to people is to cover their outdoor unit during the winter season to protect it from the weather.

Home Residents

The frequency at which you should change your AC filter is affected by everyone in that home. What does this mean? Well, it simply means that your family and the level of comfort they need affects the number of times you will change your AC’s filter. For example, if you or any other person in your family has allergies, then you are forced to change the air filter frequently.

A person with allergies will defiantly feel better if they have few symptoms. Moreover, if you have a pet in your home, you are required to change the air filter regularly.

Houston HVAC Efficiency

Changing an air filter is the beginning of saving money. According to the U.S. Department of Energy, a person can reduce the energy used by an air conditioner up 10% if they replaced their air filters regularly. This does help reduce the cost of the electric bill. Changing the air filter does also help improve airflow, which makes the AC run efficiently and properly. Remember, replacing air filters is much less compared to replacing the whole unit.

What Is A Furnace?

How Do Gas Furnaces Work?

If your home has central heating, you’re fully aware of how useful it can be when temperatures drop. Relying on space heaters in the winter can be very difficult. It is a good idea to familiarize yourself with your residential or commercial furnace and understand the basic functionalities of one. What is a furnace and how do gas furnaces work? A gas furnace is exactly what it sounds like; a furnace that’s powered through natural gas. A furnace works to heat a home during the winter. These furnaces usually work quickly, and they tend to be extremely powerful. Gas furnaces also provide cost-effective heating. How do these furnaces operate? While you’re probably not that interested in the technical details, you probably do want to know how your gas furnace operates. When you adjust the settings on your thermostat, a signal is sent to your furnace. The control board on your furnace will receive the signal and check to see if the furnace’s safeties are operating properly. It’s extremely important to monitor safeties during the heating process. AC Man Of Houston listed the top 3 important points that will break down the question we are commonly asked, “how do furnaces work.”

1. Getting Heat From A Natural Gas Furnace

Once the signal has been received and the safeties have been checked, natural gas will ignite in your furnace. The hot air generated by your furnace will be spread throughout your home through your ductwork. If at some point, one of the furnace’s safeties is triggered, the natural gas will be shut off and the furnace will shut down. This will ensure that you and your household will be safe even if something is wrong with your furnace. Your furnace will also set down once your thermostat has reached your desired temperature. If your home drops below the desired temperature, the signal will be sent back to the furnace, and the process will begin again. It’s an advanced process that’s absolutely fascinating. Obviously, not every system operates in the same way. Gas furnaces are very popular, and there are many different models on the market. While your furnace and your thermostat can change this process, this is still how most gas furnaces operate. If you suspect that there is an issue with your gas furnace, the best thing that you can do is shut down the system. Consider getting help from the best furnace repair experts at AC Man Of Houston if you are experiencing any issues, or visit a site that offers free furnace repair estimates so that you can make sure that you are getting the best price!

2. Fueling Your Residential Furnace

Home furnaces are a permanent appliance that delivers heat to space via some sort of intermediary movement. Steam, hot water, and air can all power this major appliance. Generally speaking, a heating appliance that operates via hot water or steam is described as a “residential hot water boiler” or a “residential steam boiler.” Natural gas is the most common fuel source for furnaces in North America, especially modern furnaces. Other popular fuel sources include fuel oil and liquefied petroleum gas. Furnaces fueled by wood or coal are a lot rarer. In certain areas, where electricity costs are a lot lower, homes may use electrical resistance heating. A modern furnace can reach an efficiency level of 98% if it is a high-efficiency model. These furnaces are able to operate without chimneys. The standard gas furnace usually reaches an efficiency level of about 80%. In homes without a chimney, PVC pipes are used to ventilate waste gas and heat mechanically. This can be vented through either the roof or the side of a house. The fuel efficiency of a gas furnace is measured by AFUE or Annual Fuel Utilization Efficiency. If you are having furnace problems, make sure to contact a furnace professional today.

3. Heat Distribution Throughout Your Home

Furnaces use intermediary distribution to transfer heat to a building’s living space. Typically, furnaces are referred to as boilers if that heat is distributed through steam or hot water. A major perk offered by boilers is that they can deliver hot water for showers and washing dishes. This means that a separate water heater isn’t necessary. Of course, this advantage can also be a downside. If a boiler is malfunctioning, both heat and hot water will be unavailable. It’s standard for modern “warm air” furnaces to circulate air throughout a home using a fan. Fans can also pull cold air back towards a furnace so that it can be reheated. This process is referred to as “forced air heat.” Since a fan is able to overcome any resistance provided by a home’s ductwork, the ducts can be arranged in a number of ways. In America, it’s normal to have separate ducts that collect cooler air. The cool air usually enters the furnace through some sort of air filter. It moves through the blower before entering the furnace’s heat exchanger. After this, the now warm air is distributed throughout the space. One of the biggest perks of a system like this is that it makes it easy to install a central AC system. The only thing that needs to be added is a cooling coil at the furnace’s outlet. Both warm and cool air can be circulated via the ductwork. The ducts can be insulated or uninsulated, and they can be made from sheet metal or a plastic material. If the ducts in a home have not been sealed with either mastic or foil duct tape, it’s likely that air will leak into unconditioned spaces in the building.

Common Furnace Problems

Most Common Furnace Problems

Is your furnace blowing cold air instead of a blast of warm air? Are you experiencing a loud noise coming from your furnace and are not quite sure what to do about it? Such issues are a sign of problems with your HVAC system and will be the source of worry when the winter season comes knocking at your door. Knowing the common warnings can help you take the necessary corrective measures in good time so that you can have your furnace working in at optimal capacity. AC Man Of Houston came up with a list of the 4 most common furnace problems that people come across. The top furnace problems are listed below in no particular order.

1. Loud Grinding Noise

Scraping sounds that are similar to that of metal rubbing against another metal is a sure indication of something going wrong with the blower wheel. When the furnace starts making such a loud noise, then you want to switch off the machine and call AC Man Of Houston to check your furnace immediately. The issue with the blower wheel may vary so it is important to get an expert furnace repair specialist to come out and take a look. It could be that the wheel is loose and only needs to be tightened, that is if it is not damaged. If it is damaged, then the blower wheel will have to be replaced. The problem could also potentially be a broken motor mount which can be the primary cause for the entire blower assembly shaking.

2. Loud Bang When Your Furnace Kicks On

Know there may be several things going wrong when you hear your furnace making loud popping noises when it starts to run. The two likeliest culprits would be the ignitor or furnace burner are dusty, and this keeps the burning from igniting. The result of that is a buildup of gas in the furnace that then creates the loud noise. If left unchecked, it can eventually cause the heat exchanger to crack. Moreover, it is a notable problem that poses significant safety concerns and it must be taken care of immediately. Furnace repairs may require the replacement of the heat exchanger and can also help prevent a carbon monoxide leak which in many cases can be fatal. The cause of the loud bangs may also be due to the expansion and contraction of the air ducts when the system starts blowing hot air and then the cooling after that finally begins once the furnace is off. Most homeowners with HVAC systems that have metal ducts are not new to such an annoyance. If the cause of the loud noise is the air ducts, the issue at hand could be with obstructed vents, a clogged air filter or undersized ducts.

3. Whining Noise

In case the furnace produces a high-pitched sound, the problem may be with the shaft bearings that need oiling or with the blower motor or blower belt that are faulty. If you run the furnace seasonally, then it may be easy for you to pinpoint the problems and have them fixed.

4. Furnace Blasting Cold Air

If the HVAC is producing cold air, then the issue may be due to a number of different reasons. The thermostat should be the first thing to check, which is also what any heating equipment technician will start with before looking at any other potential problems. You should check if the system is set to ‘auto’ and not ‘on’ so that the thermostat does not blow continuously and not releasing heated air. Setting it to ‘auto’ ensures that the machine only blows when the sensors can sense the need to heat up the air in the room. After the thermostat, the next thing to check are the air filters. Changing the filters every month is highly recommended because it keeps them from getting dusty and clogged up. The dust and blockage restrict the movement of air through the filters into and out of the furnace. The result of this is an overheated HVAC system which causes the equipment to stop working. The ductwork could also be the problem in that it may be installed incorrectly, it is leaking, or the wrong design was used. Such issues with the ducts could also cause the system to blow cold air and have it running continuously trying to achieve the desired heat or for a more extended period than expected to warm up the place. Besides the things mentioned above, that may be the reason behind your HVAC system blasting cold air, other causes of the heating inadequacy include normal wear and tear of the system.
