What Are the Most Common Commercial HVAC Problems?


As a business owner, you think a lot about the big picture of what you’re building. Between your products or services, you’re constantly creating new initiatives and finding better ways to reach customers. However, there are some practical pieces that are involved in running a business and maintaining the building where you’re located. While these concerns aren’t the most glamorous pieces of business management, they have to be dealt with. One of these areas of interest is your commercial HVAC system.

For your employees and customers alike, you want them to feel comfortable when they enter your facility. If you have a faulty air conditioner or heater, this can cause problems for your business overall. It’s normal to need regular maintenance and checks from a service technician to be sure your commercial HVAC is up and running in the best way. Common problems can creep up and cause small disruptions in the day-to-day operations of your commercial building. Some are easier to fix, while others may require help from a technician. Here are a few of those common problems to look out for with your commercial HVAC.

Dirty or Clogged Filters


Some problems you’ll see with your HVAC system at the office may be similar to ones you deal with at home. For example, the most prevalent issue is when you have debris or dust clogging your air filter. This can cause a lag in service, and you may start to notice that your unit isn’t pumping cold air or warm air when you want it to. Luckily, this is an example of how many commercial HVAC are easy to fix. A quick call to a technician will help clear your airflow right up. This usually just requires replacing the air filter with a new, clean one.

Refrigerant Leaks

Your air conditioner requires refrigerant to cool the air that then spreads throughout your building. Low refrigerant levels will mean system failure for your AC. This may be a result of a water leak or simply lower levels. Commercial HVAC repair can easily bring in new refrigerants to fill up your levels, so they can function as normal and get your AC unit back up and running.

Air Duct Issues

If air is being spread around your building, it needs some way to get there. Cold or warm air travels through the air ducts to change the temperature of your commercial building. If you’re having trouble with your HVAC system, it may be due to air duct obstruction. Most of the time, problems with your ducts are just because something is in the way, and it can easily be removed. Call in a professional to check out the vents and ductwork to help solve the problem.


Just like any commercial system or appliance, your HVAC wasn’t designed or built to last forever. If you’re noticing it isn’t functioning properly or that your utility bills are sky-rocketing, it may be time to invest in a new furnace or AC unit. General wear and tear can affect your HVAC system and require replacement parts or a new system altogether. Consider the longevity and age of your unit as you look into repairs or a replacement.

Thermostat Malfunctions

Sometimes your HVAC unit is malfunctioning because it doesn’t know what it is supposed to do. A broken thermostat can be a cause of your commercial HVAC not operating how you want it to. These malfunctions may cause inconsistent temperatures or untimely fluctuations. It’s easy to expect the worst and worry you need a full system reboot, but start by seeing if your thermostat may be the culprit then just replace that part.
