Why Your HVAC Unit isn’t Working

Why Your HVAC Unit isn’t Working

Having a working HVAC unit is essential for two very big reasons; the comfort of your home and the size of your energy bill. For you to get the most cost-savings, efficiency, and lifespan out of your unit, everything must be fully operational. Here are a few reasons why your HVAC unit may not be working and the causes these issues. 

Dirt Buildup

Before you panic that your HVAC unit isn’t working, check to make sure your system is clean. If you notice a drop in efficiency, it can be as simple as a little extra dirt and grime build up. When you’ve got excess dirt in your system, your home won’t heat and cool as quickly or evenly as it should. Your indoor air quality will also see a drastic reduction, meaning you might see more allergy related symptoms. Dirt and grime add wear and tear to each component of your HVAC system.

The first spot to clean is your air filters. You’ll easily be able to see all of the dust and dirt on the air filters if they are due for a change. Make sure you are changing your filters every 1-3 months (depending on the size of your home) and that you are buying the appropriate grade of filter to clean up your air efficiently. Heat pump condenser coils are another area to check. Dirty coils can degrade air flow capacity and significantly reduce efficiency. 

Age of Equipment

Have you noticed that over time your home has felt less comfortable? If this is the case, your unit may be nearing the end of its lifespan. Unfortunately, HVAC equipment can’t last forever; even with proper care, you can only extend the life by a few years. Many homeowners replace their HVAC units after roughly 10-15 years for a new, more efficient model. When you are diligent with the maintenance of your system it’ll last a bit longer. If your unit is nearing the end, and you don’t feel like it’s running as well as it should, then consider replacing your system.

Poor Installation

When your HVAC unit isn’t installed correctly, it can start running inefficiently. If this happens, you’ll see it reflected in really high energy bills and reduced heating or cooling in your home. This is why it is extremely important to choose a professional to install your system.

A few of the other problems you can expect:

  • Short circuit: if the electric voltage isn’t correct, then the unit won’t run properly. A short in the circuit will likely occur.
  • Poor results: if the unit is too small for the size of your home, then you’ll have issues getting your house to feel comfortable. This could mean uneven heating and cooling. 
  • Uneven heating and cooling: We mentioned hot and cold spots before, but when the ducts aren’t correctly installed you’ll develop air leaks, which means the temperature changes room to room could be drastic.

 Lack of Maintenance

Your HVAC system is continually working hard to ensure that your home is comfortable. Because of this, it requires a little TLC to ensure that it runs correctly. This means you should be scheduling annual maintenance and cleaning services. These checkups can find minor problems before they turn into major ones that cause your HVAC unit to break down, leaving you without heat or air conditioning. In the summer or winter months, this could be a serious problem! If it’s been a while since you had maintenance performed, you should start annually maintaining it to ensure your system is on the right track. The sooner you determine what the problem is, the more likely the repairs can be done affordably.
