Common Commercial Air Conditioning Problems

December 29, 2025
Common Commercial Air Conditioning Problems

Our air conditioners get a lot of use throughout the summer, especially in commercial settings where they might be running all the time. If you’re experiencing problems with your commercial air conditioning system, take a look at the following list of common commercial air conditioning problems and their likely cause:

Inconsistent Air Conditioning

Are employees in different areas of your workplace offering differing complaints? Some might be too hot, while others are too cold. While it’s easy to write this off as personal preference, it could indicate a larger problem with your commercial air conditioning system, specifically leaks in your ductwork. These will need to be located and fixed for the problem to be solved. Inconsistent air conditioning could also mean you have a faulty thermostat, which usually a simple fix that can save you money in the long run.

A Damaged Rooftop Unit

If your commercial air conditioning unit is on the roof, it might seem safe and out of the way. The truth is that it’s still exposed to the weather and the elements. Noise or changes in airflow might be indicators that the inside of the cabinet has been exposed to debris. It’s a good idea to get this checked out.

Ventilation Issues

Is your commercial air conditioning system to overheating or malfunctioning? Make sure that the vents are properly set up, and cleared of items that could prevent proper ventilation.

Clogged Drain Lines

The moisture in your commercial air conditioning system needs to go somewhere, and that’s where the drain line comes in. Like any system exposed to moisture, your drain lines are at risk of clogs, dirt, and algae. This can cause problems with your system, as well as leaks and water damage. Regular inspections can help keep this under control.

Strange Noises

As with many types of systems, new or strange noises can be a sign of commercial air conditioning problems that has to addressed as soon as possible. It’s best to call a professional to investigate, as this can mean a broken part, loose duct work, or something else altogether.

Blown Fuses

If your commercial air conditioning system stops working unexpectedly, it may have overheated. You may need to check your circuit breaker for blown fuses.

Burned Capacitors

While many commercial air conditioning issues can be prevented with routine inspections and maintenance, sometimes problems occur despite all efforts to prevent them. If a capacitor burns out on your system, it won’t run properly and will need to be replaced.

Capacity Issues

If your commercial air conditioning system doesn’t seem to be working properly, it could be a problem with the capacity of the system. You may be using a system that’s too large or too small for the building, either of which will lead to a dissatisfactory experience for everyone in the workplace.

Minor Maintenance Required

Commercial air conditioning will require some minor maintenance or repairs now and then, even if you’re not facing a large problem at the moment. If your system seems to be running strangely or not as efficiently as usual, different parts of the system might benefit from a simple cleaning. Taking care of these minor issues can help prevent bigger problems in the long run. A routine inspection and maintenance by a professional can help keep these sorts of issues under control. The last thing you want is for a minor inexpensive issue to become a major and expensive issue later on.

Commercial air conditioning systems are complex, and problems may occur even with proper maintenance and repair.  At LA Construction Heating and Air, we offer full array of commercial air conditioning services to help you diagnose and address any cooling or heating problem.  If you experience one of these issues and aren’t sure where to begin, don’t hesitate to contact our experienced and professional team, and get the peace of mind that you and your employees and customers deserve.
