Was My Houston A/C Repair Company Too Good? – Is Your A/C Giving You A Cold?

Air Conditioning And The Common Cold: Is There A Link?

The human body has an amazing variety of responses to cold temperatures. But None Are The A/C Repair Company’s Fault!

The idea that cold weather is tied to the common cold is a stubborn one. Despite repeated scientific inquiries, many people still hold this mistaken assumption. The greater number of colds in winter has nothing to do with the weather – at least, not directly. Colds spread more quickly in the colder months because people spend more time indoors, coming into closer contact with other people. This allows germs to reproduce and spread more easily.

Natural cold weather doesn’t cause colds. What about rooms chilled by air conditioning? To some people’s minds, there’s a real connection between entering air conditioned spaces and contracting a cold. While I believe it’s true that exposure to cold air can make it easier to get sick, I think it’s also important to bear in mind that colds can only be caught after exposure to the cold virus. So if you’ve got a new HVAC system recently, don’t go blaming your A/c repair company for your next case of the sniffles!

Let’s take a closer look at this.

When the weather outside is warm, moving repeatedly from the sunny outdoors to the air-conditioned indoors can cause some interesting bodily reactions. Remember at this point that the warm-blooded human body takes its own steps to try and keep us at our proper 98.6-degree temperature. When you move from a warm space to a cold one, the temperature change is registered by your skin and your brain is alerted. It sends back an order for an appropriate reaction. In this case, it constricts the blood vessels in the skin to keep us warm. If you look carefully, you can actually see this happen. Many people become noticeably pale when they enter a much colder air-conditioned space. In extreme cases, people may shiver – an involuntary response designed to generate heat.

It’s not just blood vessels in the skin that constrict. The same thing happens in our noses and throats. This slows down the flow of white blood cells that fight infection, and that may make us more susceptible to contracting a virus. Remember, the virus already has to be there! If there is a virus at large, we may become more susceptible by repeatedly entering air-conditioned spaces.

Of course, this effect doesn’t happen when we make the opposite temperature change. Moving into a warmer space like the outdoors in summer reverses the process. Blood vessels dilate and increase the flow of white blood cells. This boosts our immune response and makes us less likely to contract an infection.

Air conditioning can have some real health benefits. It can relieve respiratory conditions like asthma. Your air conditioner needs to be properly cared for in order to maintain the quality of the air it moves, though. Excess moisture can promote the growth and spread of fungi, bacteria, and other unwanted contaminants. An old or poorly-maintained air conditioner may actually blast those contaminants right into your body.

How do you reduce the risk of getting sick? Always drink lots of fluids. (This keeps your throat and nose moist.) Wash your hands regularly – especially at work – to reduce virus transfer. When possible, open up a window to get fresh air into your system.

Don’t wait around until your old system goes out or you find yourself in need of heat this winter only to smell the mold and dust when you kick the temperature up, Call or Contact us today to get ahead of the game!

Houston AC Repair: Why Is My Air Conditioning System Not Cooling?

AC Repair Houston: Reasons Why Your Air Conditioner Is Not Keeping You Cool

Do you have an air conditioner running in your home, yet the air is not truly cool? Maybe it is blowing out warm or just plain hot air. There are several things that may be wrong with your A/C if it is not working properly. Below you are going to find the solutions to some very easy fixes that may help you to get it running properly and what can only be fixed by a professional.

Easy Air Conditioner Problems That You Can Fix

Problem 1: Thermostat Mistakes

Do you have an A/C that blows cold air at times and lukewarm other times? This may be due to the fan setting being switched to “ON”, which is going to cause the fan to run all the time, even when the air is not being cooled by the unit. Easy Solution: Simply ensure that the thermostat is set to work on “AUTO”.

Problem 2: Air Filter Issues

A dirty air filter is going to reduce the amount of air flow in the unit, which can cause several problems. First, the unit is going to struggle to circulate the correct amount of air that is needed to bring the house to the desired temperature. In addition, the evaporator coil is going to freeze up and air will not be able to circulate at all, meaning you get almost zero cool air. Solution: Take the air filter out and examine it to see if it needs a cleaning. If you are indeed having issues with your residential air conditioner, contact an ac repair Houston professional today.

Problem 3: Dirty Unit

The way an air conditioner cools a house is a rather simple process. The evaporator takes hot air in and transfers it to the outside unit known as the condenser. However, if the condenser is dirty or covered, it is not going to be able to dissipate that heat correctly. This causes the unit to overwork and not be able to cool the home properly. Solution: Gently clean the outside of the unit with a garden hose, clearing off the debris. It is important that you do not spray the unit with the hose on the highest setting as this may bend the fins that allow airflow to the condenser. While you are outside, be sure to remove all tall weeds and leaves away from the unit. You want your unit to have the ability to breathe on those hot summer days too! A clean and well-maintenanced air conditioner will bring about better indoor air quality.

Problems Only An AC Repair Houston Expert Can Solve

There are going to be problems that only a ac repair Houston professional can take on, these are just a few of them.

Problem 1: Broken Or Faulty Condenser Fan Motor

If the init’s fan has gone bad, there is no way that it can dissipate heat, which simply means you are not going to get any cold air.

Problem 2: Low Refrigerant

The refrigerant that is found in the unit is the key ingredient to absorbing the heat from the air. When there is not enough refrigerant in the unit, it is not going to be able to cool the air. If you do have low refrigerant it more than likely means you have a leak. Some typical signs that you have a leak include:

  • Ice found on the outside of the unit and refrigerant line.
  • A hissing or bubbling noise coming from the unit.
  • The unit can not cool the home on hot sunny days but is able to work fine in the evening or on cool days.

If you see any of these signs, it is time to turn the unit and call an ac repair Houston professional as soon as possible. When you run the unit in this state, it is possible to damage the unit beyond any possible repair.

Problem 3: Faulty Compressor

The compressor of your unit is the heart of the system, it is the part that circulates the refrigerant through the unit and helps to cool it. If this part is damaged, the unit is going to be unable to cool the house. If the compressor is damaged, it is going to need to be replaced. However, this can be a rather expensive process. If you do not have a warranty on the unit, it may be best to simply replace the unit at this point.

Houston Air Conditioning Repair: What Is The Life Expectancy Of My HVAC System?

Air Conditioning Repair Expert: The Life Expectancy Of Houston HVAC Systems

How long will it last? As an HVAC Houston expert, this is one question we get asked by almost all our clients every time we install a new HVAC system for them. The answer it depends. On what? Well, on how you maintain your system. Manufacturers make their systems slightly different from other and one system could last much longer than the other. For instance, if a Houston HVAC uses low-quality compressors in its systems, then the overall life expectancy of its systems will significantly drop since it is often more expensive to replace compressors than it is to replace the entire system. Below is a chart outlining the average life expectancy of a Houston HVAC system based on national averages, old estimates and how much maintenance it requires. Please remember that these are simply estimates and not guarantees. Therefore, the brand you go for could possess lower or higher life expectancy. If you are in need of assistance from a professional Houston HVAC repair company, you are in the right place.

Maintenance Tips For Your Houston HVAC System:

• Change the system’s filter regularly (preferably every 1-3 months)
• Get seasonal servicing and tune-ups
• Remove any debris within the unit
• Check and replace refrigerant insulation if need be

Zero Maintenance

 (0 items)

Light Maintenance

 (1-2 Items)

Medium Maintenance

 (2-3 Items)

Heavy Maintenance

 (4 items)

Between 15 to 18 yrs Between 18 to 20 yrs Between 20 to 25 yrs 25 plus yrs

Houston HVAC System Exclusions

The chart above is for an average central heating/AC system; if you still use wood stoves, oil burners or any other form of heating, then your numbers will be significantly different. Oil-based furnaces tend to last a couple of years at most and require tons of maintenance for them to run optimally. As more traditional systems, they can last a couple of years and aren’t too expensive, making them a popular option for some. Geothermal systems also aren’t included in the chart but generally last about 30 years and more. When well-maintained, these systems can last much longer than you! Boilers, on the other hand, tend to follow the chart, except that they last a bit long 1 to 3 years longer than the average HVAC system. Some additional accessories and features not included include:

  • Dehumidifiers  8 to 10 years
  • Humidifiers 8 to 10 years
  • Duct/Ventilation Work  8 to 10 years
  • Insulation 100 years
  • Thermostats  35 to 40 years

Each one of these has their own life expectancy depending on the specific brand.

Average Life Expectancy Of A Houston HVAC System

Most HVAC Houston companies and organizations agree that homeowners can get anywhere between 15 and 25 years of service from the system. Some will say 15, some 20, and others 25. However, the truth is that your system will last as long as you’d want it to. As long as you are maintaining your system and have it serviced and tuned up often, your system should last you a very long time. Most homeowners in Houston decide to have theirs replaced by a professional HVAC Houston service provider for a newer, more efficient models after about 10 to 15 years. In the long run, having your system replaced every 15 to 20 years (which is the average life expectancy for most systems) is generally more economical considering the savings made from lowered energy bills and maintenance fees.

#1 Air Conditioner Repair Houston Expert: How Often Should An A/C Be Replaced? 

A Guide On How Often Your AC Needs To Get Replaced By A Top Air Conditioner Repair Houston Professional

One of the hardest decisions for any homeowner to make is when it’s time to get a new air conditioner or repair it. While a new air conditioner can be rather expensive, in many cases it is the best decision. However, knowing when it is time to get a new air conditioner can be difficult to understand. Below are six signs that are going to help you make the right decision. We understand that deciding whether you should replace or repair an air conditioner is difficult. There are many times when an old AC still has many years of life in it and does not need to be replaced. This guide was written to help you save money and make the best decision possible. So, let’s get right down to the nitty-gritty and find out whether you need to repair or replace your air conditioner.

Over A Decade Old Air Conditioner

In many cases, the typical lifespan of a well-maintained air conditioner is about 15 years. However, if your air conditioner is 10 years old and needs extensive repairs, is more than likely best to replace it. This is especially true when you look at all the advances that have been made in air conditioning technology within the last few years. If your AC is this old then it is time to reach out to your #1 source for air conditioning maintenance and repair services in Houston.

An AC That Is Inefficient

If the air conditioner you are using right now has a low SEER rating, it is costing you more to run it than it is worth. New air conditioners on the market today must have a rating of at least a 13. If the air conditioner in your home or business has a SEER rating that is under 13, by replacing with a new air conditioner you are going to cut your energy costs dramatically.

Extensive A/C Repairs

If the unit that is being worked on has an extensive repair last, it is best to weigh the costs of replacing it. If the amount to repair an older unit would cover the vast majority of a new unit, it is typically going to make more sense financially to invest in a newer unit.

AC Is Constantly Breaking Down

Do you have an air conditioner that seems to break down every other week or month? Do you know the air conditioner repairman by the first name? This probably means your air conditioner is breaking down more often than it should. These types of repair bills are going to add up really quick, and it makes no sense to keep a unit in this condition. We recommend remain in friends with your air conditioner repairman, but letting the unit go.

A/C R 22 Freon

Freon is one of those chemicals that has been slowly phased out by the federal government in an effort to conserve energy across the nation. Due to this phaseout, the cost of Freon has risen exponentially over the years. If you are using an air conditioner that runs on Freon, it is going to have to be replaced eventually. If your air-conditioner is giving you major troubles and it uses Freon, is simply just a good idea to purchase a new unit.

Air Conditioner Is Not Cooling Your Home

Does it feel that your home is almost as warm as it is outside? This is a problem with an air conditioner system that is not running as efficiently as it should. It also may be an incorrect size were simply too old to function as it should. If your air conditioner is not able to keep your home cool, it is time to replace it with the unit that can.

Katy TX A/C Repair: Learn How To Clean The Air Conditioning Evaporator Coils

Katy TX Air Conditioning Repair: A Guide On How To Properly Clean Evaporator Coils

Regular preventive maintenance is essential in making sure your air conditioner continues to work properly. You should have maintenance performed at least once per year before the cooling season begins. Season maintenance should be performed by a professional air conditioning repair Katy TX company. Tasks that should be performed include system adjustment and testing, component replacements, minor repairs, air filter changes, and cleaning condenser coils and evaporator.

The Basics Of Cleaning A/C Evaporator Coils

Check and clean the evaporator coils as needed. Monthly cleaning might be required if the coils tend to easily collect debris and dirt. Otherwise, you might need to clean them out every three months or so during the cooling season or yearly as part of your regular preventative maintenance. AC Man of Houston offers maintenance services for commercial properties.

Gaining Access To Clean The A/C Evaporator Coils

There should be an access to the indoor air handling unit that you can remove in order to get to the evaporator coil. Check your owner’s manual if necessary to find the evaporator coil and access panel. On the thermostat, turn your air conditioner off. To get the access loose, remove the screws or another type of fasteners. Set the screws and panel aside where you won’t separate or lose them. Check out our residential services by clicking here.

Using Compressed Air To Clean The A/C Evaporator Coils

  1. You can use compressed air to remove light accumulations of materials such as dirt by blowing them off of the evaporator coil.
  2. Direct the compressed air over the coil. Move in the opposite direction of regular air flow from the cleanest to the dirtiest side.
  3. For pieces that are more stubborn, take the air nozzle and please near the bottom part of the debris. If high-pressure air is being used, direct it either through the fins directly or at a 90-degree angle. That will prevent the fins from getting damaged.
  4. Maintain consistent airflow over the coil. That will dislodge the buildup without it being further forced into the fins which will make it harder to remove.
  5. Avoid blowing debris, dirt, and dust into the living spaces of your home or into your ductwork system. Wear eye protection so that material is kept out of your eyes. Use a shop vacuum, if necessary, to collect the material as it is being dislodged.

Using A Brush To Clean The A/C Evaporator Coils

Brush cleaning is a very effective way to remove minor dirt accumulations from the evaporator coils. It enables you to avoid having to use chemicals or liquid and provides you with greater control in terms of the amount of pressure applied to the fins and coils.

  • Apply your brush to the evaporator coils to sweep away dirt accumulation.
  • Use the brush to scrub and break lose materials that are harder to remove.
  • Avoid using a hard-bristle brush or wire brush since the might damage the fins.

Using Commercial Cleaners To Clean The A/C Evaporator Coils

There are several commercial cleaning brands that you can use to clean evaporator coils. A majority of them are foaming kinds that break down and then drain into the drainage system of the unit. Consult with a reputable local HVAC contractor for recommendations on the best clean to use for your specific situation.

Using Water And Mild Detergents To Clean Your A/C Evaporator Coils

Instead of using a commercial cleaner, warm water and a mild detergent can be used for cleaning the coils.

  • Mix a simple detergent and warm water into a spray bottle, garden sprayer or hand sprayer.
  • Apply the detergent and water solution to your evaporator coils.
  • Let the solution soak in for a few minutes to that it can soak in and also loosen debris.

The #1 AC Repair Company In Houston Shows You How To Turn Off The Power To Your Air Conditioning System

Top-Rated AC Repair Company: How to Shut Off the Power to Your Air Conditioner

When you are repairing your air conditioner or installing a new unit, you must turn off the power to the unit. Turning off the power not only protects you from getting shocked, but it also protects the equipment from power surges that can damage the unit. Before turning off the power, you need to turn off the heating and cooling system by turning off the thermostat. If you are considering changing out your thermostat to a new Nest thermostat, you will want to ensure that the power is completely off for your thermostat and your heating and cooling system. If you are unsure how to install a new thermostat, install a new heating and cooling unit or repair your existing system, an AC repair company can help.

Switches That Control The Cooling And Heating System

You will need to determine which switches control the heating and cooling system in your house. Most of the time, these are found in your breaker box or fuse box; however, many units will have a separate breaker box located outside next to your heating and cooling system. It is important to know that if you have a split heating and cooling system, there may be a switch, fuse or breaker for the heating system and a separate switch, fuse or breaker for the cooling system.

Breaker Box

Most of the time your breaker box will be labeled. If your breaker box is labeled, you can flip the breakers for your heating and cooling system. If your breaker box is not labeled, you can either try to find the breakers that control your heating and cooling system or simply shut off the main breaker. If you opt to shut off the main breaker, you should be aware that it will turn off all power to your home. If you shut off only the breakers to your heating and cooling system, verify that all power to the heating and cooling system is turned off by attempting to turn on the heat setting, the cool setting and the fan of the system by using your thermostat.

Switches May Look Like A Breaker Box

Certain heating and cooling systems will not have a breaker in the breaker box. Instead, it will have a separate small breaker box located near the heating and cooling system. These stand-alone switches may look like a breaker box, or they can look like a light switch. If there is a switch similar to a light switch near your heating and cooling system that does not control a light, switch it off to ensure power to your heating and cooling system is off. Once you have installed your new Nest thermostat, you will need to turn the power back on. If you shut off the main breaker to your house, you will need to reset all of your electronic devices and clocks. If you are in need of AC repair company services for your residential property, click here.

The Five Installation Steps to Follow After Installing a New Thermostat

  • Step 1 – Turn off your heating and cooling system at the thermostat. Slide the lever to the off position. Doing this will prevent your thermostat from turning on when you turn the circuit breaker on.
  • Step 2 – Go to your circuit breaker box. Your circuit breaker box can be in several locations, such as the garage, the basement, your laundry room, in a closet or on the exterior of your home.
  • Step 3 – Reset the circuit breaker for your heating and air system. Find the breakers that are marked heating and cooling and move them to the on position. If the breaker is in the neutral position, you will need to turn the breaker off and then back on.
  • Step 4 -Wait 30 minutes. Your heating and air system must have time to reset the internal circuit breaker.
  • Step 5- Turn the thermostat to cool and begin enjoying your new Nest thermostat. If your breaker trips when you turn your thermostat on, you may have another issue. Try resetting the circuit breaker. Call for immediate assistance. If this does not work, contact your local AC repair company.

Refrigerant is a dangerous substance and requires a professional touch.

2. Evaporator Coil

Is your unit having trouble pumping out cool air? There could be ice on the evaporator coil. Most often, this is the result of air filters that are not clean. In addition, if airflow isn’t very good because the vents are closed, there could be an issue with ice as welhttps://acmanhouston.com/understanding-your-ac-condenser/l . In order to solve the problem, make sure the vents are not closed. Switch out the filters and then get rid of the ice on the coil.

How An Expansion Valve Works

AC Man Houston | Houston HVAC PartsWhat An Evaporator Does

The evaporator is located in the top of the system unit and is comprised of coils. This is the case for most air conditioners, but not all. Refrigerant will goe from the condenser to the evaporator in its cooled, liquid state.

Once the refrigerant is there, it meets with low pressure. This low pressure turns the refrigerant into a gas. The gas then absorbs heat from the air. It is the absorption of heat that cools your home’s inside. Once this process is complete, the gas goes back tot he condenser and it happens all over again.

Why The Evaporator Is Important

Without an evaporator, the air conditioner would not cool the air in your house. When the evaporator turns the refrigerant into gas, it allows the refrigerant to do its job of getting hot air out of your house.

Maintain Your Evaporator

Your evaporator works hard to keep your home cool. This is why it is important to maintain it. The first step is to keep the coils clean. If they are not clean they trap dirt and block the absorption of heat. Coils should be kept clean even during winter. Moisture on the evaporator can freeze causing it to perform inefficiently.

If you ever notice a change in the way your air conditioner cools your house, get in touch with an HVAC expert at AC Man Houston or you can call us now for immediate assistance. We will schedule an appointment for either a repair or maintenance to keep your home as comfortable as it needs to be.

Understanding HVAC Parts in Houston – The Condenser

Whether summer is well underway or you merely live in a warm climate, you probably have your air conditioner on more often than not. (That’s especially true in the Houston area!) Unfortunately, it’s easy to take an amazing machine like an AC for granted. We tend to act as if they’ll always turn on without a hitch, but all of the intricate inner workings are prone to developing several problems over time. For instance, just take the all-important condenser into consideration.

How An HVAC Expansion Valve Works

What Does An Air Conditioner Condenser Do?

AC Man Houston | Houston AC RepairAs your HVAC system chugs along in an effort to cool down the air in your home, it actually absorbs the heat within the room and then releases it outside. This ever-important action relies largely upon the condenser. The part of the unit facing or located outdoors generally hosts this part so that it can dispose of the absorbed heat properly.

As liquids are turned into gases, there’s a natural degree of heat absorption. On a scientific level, this is precisely what’s going on as your air conditioner works to cool you down. It also has liquid refrigerant that works in tandem with an evaporator to take the heat away. Once this happens, the liquid can turn into a gas. The room can’t be cooled without the absorbed heat being released, however. That’s precisely where the condenser comes into play.

As the gas form of the refrigerant is put under a specific amount of pressure, the heat can then be released outdoors. The refrigerant then turns back into a liquid. It all sounds quite complicated, but the basic premise is quite simple, and a well-kept HVAC system can handle the job without issue.

General Condenser Maintenance

As alluded to earlier, the inner workings of an air conditioner are quite intricate, and one part relies on the next for the entire system to remain in working order. Some of the essential parts are the fans, coils, motor, tubes, and so on. After repeated use and years of wear and tear, these parts can break down. The condenser, of course, is no exception.

If you want to keep this from happening, be sure to clean it on a fairly regular basis. Otherwise, debris from the elements outside will build up quite easily. Cleanup is as simple as spraying the part with a water hose, so there’s no excuse to let it slip by.

You should also do your best to cut down on the amount of debris that might come into contact with the condenser. This means cleaning your yard regularly as well. Make sure to remove any leaves, loose grass, and stray limbs that might be nearby.

If you take good care of your condenser and you notice it’s still having a hard time, it’s likely time to consult a professional. AC Man Houston is proud to provide you with the best AC repair in Houston TX.

How An HVAC Expansion Valve Works

HVAC Parts 101: The Expansion Valve

Among the various comfort appliances that we have in our homes and businesses, the vast majority will reckon that the central air conditioning system is indispensable. Cooling our homes in the host summers make their presence ever-more appreciated. However, the entire system could not work properly without the various components and parts working together and properly to keep your home or business cool all year. It is thus important for homeowners and business owners to have at least a passing idea of the various components of the system or you may end up needing Houston TX AC repair.

Herein we are going to delve into the expansion valve, which is an integral part of the system.

What Is An Expansion Valve And What Does It Do

To understand what an expansion valve is, you need to first understand how the cooling function of AC systems works. Air conditioners usually work by moving a refrigerant throughout the HVAC. The refrigerant changes from liquid to gas back to form a complete cycle. In this regard, the cool liquid refrigerant is pumped into the house or business premises, where it absorbs heat.

Due to absorbing the heat, the refrigerant turns from liquid to gas. The gaseous refrigerant moves to the exterior portion of the HVAC where the absorbed heat is released, cooling the refrigerant and turning it back into a liquid.

However, even though at this stage the refrigerant tends is cool, it is usually never cool enough to absorb heat once it is pumped into your home or business as the temperature difference is usually negligible. This is where the expansion valve comes in. The Expansion valve expands the liquid refrigerant by rapidly reducing the pressure under which the liquid is in, cooling it very fast.

AC Man Houston | HVAC Maintenance in Houston TXCharacteristics Of A Failing/Failed Expansion Valve

These are the sign that the expansion valve is faulty:

  • Frozen coil
  • Constantly running system
  • Lack of cold air from your A/C
