By Aiden ArmstrongA commercial HVAC system has many components, but the compressor is the most important part. Often called the heart of a cooling system, compressors are reliable and perform a vital function. In fact, a compressor should last at least 10 years in most commercial applications. However, if your cooling system is having a lot of problems lately, it might be time to think about HVAC compressor replacement. In fact, this strategy can greatly increase cooling efficiency.
Signs of a Failing Compressor
Sometimes a compressor will give you notice before it goes out or quits working completely. It’s vital to pay attention to these things, so you don’t have to deal with a lot of HVAC downtime issues. Compressors often go out in the hottest of weather, and this could cost you a lot of business.
Warm Air
Feel the air coming out of the vents? Is it warmer than it used to be? This can be a sign of a failing compressor, but first it’s important to rule out other problems. If the refrigerant levels are in spec, other components are working and the system is clean, your compressor should be checked.
Hard Starting
When the condenser unit kicks on, is there a lot of vibration and noise? Before a compressor hangs up it often will have a hard time starting up. When you notice this, it could be time for HVAC compressor replacement.
Circuit Breakers Tripping
Any HVAC unit will stop working if a breaker is tripped. Naturally, all you have to do is reset the breaker and everything is fine. When a compressor becomes tired and worn, it will generate more heat and draw a great deal more current, especially at start up. Frequent circuit overloads could mean a failing compressor, and the compressor may kick out on overload at times.
Funny Noises
It’s not uncommon for commercial or industrial condenser units to make quite a bit of noise as they run. After all, they are heavy duty units. However, if your unit has suddenly become much louder than normal something may be wrong. A bad compressor can be very noisy and make unusual sounds when it runs.
Have Your System Checked Out
If you have your own AC maintenance personnel, make them aware of any unusual noises or problems with your cooling system. If not, it’s time to call in HVAC professionals to inspect your system. If your maintenance man recommends HVAC compressor replacement, make sure to go with a name brand unit like Carrier, Trane, Copeland or York. In addition, you can save a lot of money if you install a quality remanufactured compressor.
