Simple Steps for AC Compressor Maintenance

If your HVAC system malfunctions, one of the most likely culprits is the AC compressor. However, while it is a component given to causing problems, it is also actually very simple to maintain. You can easily save yourself from the headache and the money later on with a few basic checks.


Many compressor-related issues can be solved just by keeping it clean. This mostly just entails clearing any debris out of the unit, and regularly cleaning the filters. Both problems can obstruct and contaminate air flow, and both problems can be easily identified and corrected.


Being wary of your local climate—especially cold weather—can prevent a wide variety of possible malfunctions in your compressor. For example, freezing and thawing of components in the unit can quickly age and damage the compressor. The addition of a small heater in the unit, along with basic maintenance, should prevent such weather-related damage.


It is important to ensure that there is always enough refrigerant in the system—but you do not want to overdo it either. Running for extended periods of time on too little or too much refrigerant puts a lot of strain on the compressor. The actual process of “re-charging” (the term for re-filling) the system is best left to an HVAC professional. However, being aware of your HVAC maintenance schedule can ensure that your refrigerant levels remain optimal.
