HVAC Repair Technician Tell-All – Heaters Not Heating?

Furnace Blowing Cold Air, Do I Need An HVAC Repair Technician? – How To Troubleshoot The Problem.

Are you turning on your furnace, but it is blowing cold air? Are you wondering what is wrong? Well, the truth is that it could be multiple issues, of which some of them you can solve. Before you go right ahead to call a professional HVAC repair Technician, below are 4 troubleshooting techniques that will help.

1. The Thermostat’s FAN Setting

Is your furnace blowing cold air sometimes and hot the other? Well, the problem could be the thermostat’s fan setting, which may be at the ON position. It is important to note that the blower is controlled by the Fan setting control. It is the system that helps circulate air through your home. As such, if it has been set to ON, the blower will run all the time (24/7), regardless of whether the furnace is heating or not. This may be the reason you are getting cold air.

The solution? The only solution to this problem is to ensure the fan setting has been set to AUTO and not ON. The AUTO setting will ensure the fan will run only when the furnace heats the air.

2. The Furnace’s Air Filter

If your furnace is blowing cold air, the problem could be its air filter (meaning it is too dirty). When the air filter becomes too dirty, it limits the flow of air to the furnace’s heat exchanger, which makes it overheat. When this happens, a high limit switch will be tripped, which shuts off the furnace banners to prevent cracking.

The Solution? The solution is to first turn off the furnace at the thermostat and inspect the filter. If it is too dirty, changing it is the only way. You may also need the services of a professional HVAC repair technician to help you reset the furnace. Filters are generally located next to the blower in many models.

3. Inspect The Pilot Light

If you have an older furnace model with a standing pilot light, then you should inspect it. if the pilot light is not lit, then it means that the furnace’s burners will light, which means no heat.

The Solution? You should try relighting the pilot light. Below are steps to follow.

  • Switch Off The Furnace – This includes switching the thermostat from HEAT to OFF.
  • Locate The Furnace’s Pilot Light Assembly and Reset Switch – The switch and assembly are generally located near the bottom of the furnace. If you cannot locate them, then refer to your furnace’s manual. You must open the cover to access the reset switch. You should see a knob with 3 settings; ‘ON’, ’OFF’, and ’Pilot’.
  • Turn The Knob ‘OFF’ and Wait for at least 3 minutes – Doing this will shut the gas flowing through the pilot.
  • Turn The Knob To ‘Pilot’ and Press the Knob Down – By doing this action, you will be restarting the flow of gas to the pilot.
  • While Still Pressing The Knob, Hold a lighter to the pilot opening Until The Flame Lights – The flame should have a steady blue cone and hit the middle of the thermocouple (this is a small copper bar)
  • Turn The Knob To The ‘ON’ Position – Now the furnace should ignite.
  • Turn ‘On’ The Furnace At The Thermostat
  • Turn the thermostat back to ‘HEAT’, and ensure the temperature is set 5 degrees below the room temperature. After doing this, you should be getting hot air.

What To Do If The Pilot Light Does Not Light Or Stay Lit

Well, this is the point you call a professional HVAC repair technician. The problem may be a malfunctioning thermocouple or other issues that make the pilot light not to burn properly.

4. Inspect The Condensate Line

If you have a high-efficiency furnace and you see water pooling around the furnace, then most likely the condensate line is blocked. The line is usually a PVC pipe. This problem will make the furnace to shut down.

How? You may ask.

High-efficiency furnaces create water when running, which is then drained to the common house’s draining line. However, if the condensate is blocked, water begins to back up into the furnace. At this point, the overflow will trip a kill switch, which will turn off the furnace to prevent water damage.

Common causes for blockages include:

  • Mold
  • Dirt
  • Dust
  • Ice
  • Broken condensate pump (in this case, you will need the services of a professional HVAC repair technician)

The Solution? Apart from broken condensate pump, the rest can be solved by simply unclogging the line. You can achieve this by following this tutorial on Energy Vanguard.

AC Heroes: The Ultimate Air Conditioner Air Filter Guide

A Basic Guide To Understanding AC Air Filters

What Do You Risk By Installing The Wrong AC Air Filter?

Professional HVAC technicians recommend replacing air filters every three months at a bare minimum. Changing filters on a monthly basis is ideal for maintaining optimum air quality in your home. There are other benefits to frequent filter changes, though – one’s technicians care about even more than indoor air quality. A clean filter does a better job of protecting your air conditioner. That is, in fact, the filter’s primary purpose. If you installed the wrong filter, you may be putting your air conditioner at significant risk.

How Your AC Air Filter Really Works

While modern filters do an effective job of filtering allergens and other unwanted contaminants out of the air in your home, their point and purpose remain to safeguard the equipment in your AC system. Without a filter, your air conditioner could easily suck in particles large enough to damage its working parts. A filter needs to defend against this possibility without unduly restricting the amount of air flowing through the system. As a filter accumulates more particles, it also starts restricting more airflow. This is why your filter needs to be changed regularly to keep the system running smoothly.

Considering An Air Filter Upgrade?

An increasing number of homeowners are interested in improving the quality of the air in their homes. This leads many people to consider installing more potent filters in their air conditioning systems. The problem here is that a densely-woven filter that traps very small particles may also reduce airflow so significantly that your HVAC system cannot work efficiently. Fortunately, both air conditioners and filters are rated to protect against this situation. Every filter has a Minimum Efficiency Reporting Value or MERV. Standard residential air conditioners usually operate with filters in the 1-4 MERV range. Depending on your specific equipment, though, your system may accommodate a filter as strong as MERV 8. AC air filters that is too strong for your air conditioner might inadvertently cause damage.

A Better Option: A Whole-House Air Purifier

If the quality of the air in your home is unsatisfactory, there are many possible causes. Some potential contaminants are easy to diagnose, like dust, dirt, and the presence of pets or smokers. There are other sources that are harder to detect and which might be impossible for you to solve on your own. Examples include automotive contaminants from nearby roads or construction particles from nearby work sites. If you are looking for repair solutions for your home ac, check out AMH.

How Mechanical Air Filters Work

The range of purifiers and air cleaners currently being sold today operate on
a number of different principles in order to improve your home’s air quality. In many situations, the most effective solution is also the most straightforward one. A “mechanical” air filter, for example, is simply one that attaches directly to your home’s air ducts. It uses no electricity or moving components, relying strictly on their material construction to filter the air moving through your ducts. Because the pollutants being filtered out of your air are trapped in the filter, it needs to be changed regularly to maintain both air quality and heating/cooling efficiency. Consult with professional service technicians to confirm that you’re using the right air filters for your air conditioning system.

Electronic Air Purification

An electronic air purifier or cleaner is an option worth considering if you want to take more active steps to improve your home’s air quality. Electronic air purifiers rely on a range of different techniques – often in combination – to remove pollutants from the indoor air you breathe. In an electrostatic precipitator, for example, pollutants are given an electrical charge so that they will be attracted to and trapped on a collector plate. All the pollutants thus collected can be easily disposed of by removing the plate and cleaning it.
