Because summers in Southern California can be so hot, many business owners in the Rancho Palos Verdes, CA area may be skeptical about installing new air conditioning units on the roof of their business.

Signs that You Need to Have Your Commercial HVAC System Repaired

Friday, February 20th, 2015

Commercial HVAC systems operate with much higher stakes than most home HVAC systems. If your home heating or air conditioning system breaks down, you’ll be inconvenienced for a day or two while you wait for repairs.

If the HVAC system in your place of business breaks down, however, it can have a substantial effect on both your employees and your customers. For that reason, it’s always a good idea to familiarize yourself with the warning signs that your commercial HVAC system needs repairs.

Let’s take a look at some of those signs.

Odd Noises

After using the same HVAC system for a while, you should be familiar with the usual noises it makes during operation. Any deviation in those noises could be in indication that your HVAC system is in trouble. There are a few specific sounds that you should listen for. Grinding indicates that your air handler is having issues. The air handler motor is placed under a lot of strain during operation, especially in large commercial systems. To compensate for this strain, the motor is equipped with lubricated bearings that help reduce friction on it.

When these bearings start to wear down, however, the friction on the motor gradually starts to increase. If the worn out bearings are not replaced, the motor will overheat and burn itself out. Other common problem noises include booming, hissing, and gurgling. Each of these has different causes, but all require professional attention.


Short-cycling is the name for when your system rapidly turns itself on and off throughout the day. It is caused by the system overheating, which activates an emergency shutoff device called the “limit switch.” When the system cools off sufficiently, it starts up again and overheats again, and the entire process starts over. Short-cycling is a sign of a major problem with your HVAC system, and should be addressed immediately. If you notice this happening, turn your system off and call a professional.
