The Most Common Commercial HVAC Problems

Did you know that Willis Carrier patented an “Apparatus for Treating Air” as a means to solve a humidity problem? Commercial HVAC systems have come a long way since and are seen as a staple in our daily lives. Knowing how to spot HVAC issues is important if you own one.

So keep reading to find out more about the most common HVAC problems and how you can tell if your unit needs repairs.

It Isn’t Cooling

Cooling is the main functions of an HVAC unit, so if it isn’t doing its job, you have a problem.

HVAC units need refrigerant, a liquid that is used to remove heat and help the production of cool air. If there is a problem with the refrigerant, then the unit won’t be able to cool the air. Insufficient refrigerant is one of the most common problems when it comes to fixing an HVAC unit.

You can either take a look yourself to see if there is enough refrigerant, or you can phone a professional to inspect your unit for you.

While refrigerant is needed to cool down the air, evaporator coils are also an important aspect of the unit. The coils can freeze over, which interferes with the equipment’s ability to cool. Luckily, it can easily be fixed by defrosting the coils.

Not Running Efficiently

If you realize that your monthly heating or cooling bills are significantly larger, it can be a sign that your HVAC isn’t running efficiently. Your bills increase because the unit has to work much harder to achieve the same result, so it ends up running for much longer than needed.

If you can’t explain the sudden spike in your bills, it might be time to call a professional like https://www.kahnmechanical.com/commercial-hvac-maintenance-dallas/ to take a look.

Reduced Air Quality

Air filters remove dust, pollen, and other material from the air as it moves through the unit. The material gets trapped in the air filter, leaving your indoor air clean and fresh.

If it seems like the air quality has gone down, it might be time to replace the air filters as they can become clogged and can hinder cooling and heating as less air gets pushed through.

Strange Noises

Noises that you haven’t heard before, or sudden loud noises, might be a sign of trouble. While it can indicate that your unit needs lubrication, it can also indicate a fan belt needs to be changed.

So if you are suddenly hearing noises from your unit, you should have it checked out as soon as possible.

Spot HVAC Problems Easily

Spotting HVAC problems early can save your unit. You might need to have some work done if the issue is serious, but catching it early can reduce the risk of needing the unit replaced. So if you think you are having HVAC issues, you should call a professional to take a look.
