Two basic maintenance tasks will greatly improve the performance and longevity of any compressor. Keeping the condenser coil and evaporator coils clean to absorb and reject heat. A technician should check your system four times a year to determine if it is operating properly. The following is an example of why this is important. In the spring or fall, you may be cool in the store while the HVAC unit is low on refrigerant. If it is operating at 50% capacity, it will still meet your cooling needs.
However, the unit is low on refrigerant, resulting in high superheat. Compressors depend on cool refrigerant gasses returning to cool the motor and when that does not happen, the motor overheats, stressing the motor and shortening the
life of the compressor. A comprehensive maintenance program is listed below. Following this schedule with qualified technicians will go a long way to prevent compressor failures.
