Commercial HVAC Problems

5 Common Commercial HVAC Problems

Commercial HVAC Problems: To run a successful business, you must ensure that everyone who enters your building feels at ease. Commercial HVAC systems are held to a higher standard of performance as a result.

Commercial HVAC systems and the equipment they house may take a battering, depending on the operation hours and the area’s temperature. They’re indeed built to withstand the rigors of the job. However, as the years’ pass, those systems’ abilities will erode due to wear and tear and the ravages of time.

As a result, frequent HVAC maintenance inspections are critical to guarantee that your systems operate at their peak performance. If a business HVAC specialist notices any inefficiencies during these inspections, they’ll be able to offer cost-effective ways to fix the problem before it gets out of hand.

Don’t worry if you don’t have much experience with business HVAC servicing; we’re here to assist. We’ve compiled a list of the most frequent HVAC issues (and how to address them) that may save a company money in the long run.

5 Common Commercial HVAC Problems


Leaks in Your Compressor


In this category, leaks and jumbled compressors are the most prevalent problems.

A refrigerant leak can be detected by looking for oil around the service ports, valves, solder connections, and compression fittings.


You may hear the sound of a scrambling compressor. Compared to a conventional compressor, a scrambled compressor can operate substantially louder. The hum of a locked rotor or a compressor’s repetitive starting and stopping (short cycle) indicates a problem with the refrigerant charge.


A Clogged Condenser


This is one of the most common commercial HVAC problems. Clogged or filthy coils may impede the airflow through condenser coils. Coil fins can become corroded by salt or chemicals, restricting airflow and reducing heat transmission. You can alleviate this problem by implementing a bi-annual HVAC coil cleaning routine.


A malfunctioning condenser fan can restrict airflow and finally lead to the unit’s demise. Short cycle (repeated starting and stopping due to thermal overload), excessive fan blade vibration, degraded wiring or connections, and improper speed/direction of the fan are all signs that something is wrong with the fan.


Malfunctioning Economizer


When the outside air temperature (OA) is below 55 degrees Fahrenheit, you may determine that the economizer isn’t working effectively. When the temperatures are lower than that, the return dampers should be closed and the OA dampers open. Economizers can fail because of a lack of cleanliness. There is a risk of malfunction if dirt accumulates on dampers, gears, linkage, or controls. The economizer can also malfunction if the exterior air filters are damaged or missing. Filter problems and dirt buildup may be avoided if correct maintenance procedures are followed.


Dirty Evaporator


The evaporator coil is the principal target of the air filter’s protective efforts. A dirty evaporator can be caused by clogged air filters, which enable air to flow through the filter and into your system. Airflow is impeded as dirt builds up on the coils’ surfaces. Dirt buildup can negatively influence heat transmission and operating efficiency, leading to further commercial HVAC problems and final collapse.


Poorly Fitted Panels


Another common commercial HVAC problem is when there are issues with the unit’s housing, it’s easy to see them. Panels that are deformed, don’t fit properly, or lack insulation is potential issues (especially common with older units).


Commercial HVAC Problems: Conclusion


There are a few common issues that can arise in commercial HVAC systems. Most of these can be prevented through regular maintenance, inspections, and other commercial HVAC services.
