Another vital aspect of maintaining airflow is regularly checking and changing the air filter. A dirty or clogged air filter restricts the airflow, forcing the compressor to work harder than necessary. This extra strain can lead to premature wear and tear, reducing the lifespan of the compressor. Regularly inspecting and replacing the air filter will help keep the compressor running smoothly.

Additionally, keeping the evaporator coil clean is essential for improving the AC’s energy efficiency. A clean evaporator coil allows for better heat transfer, reducing the workload on the compressor. Regularly scheduling professional maintenance visits can ensure the evaporator coil is properly cleaned and maintained.

Tips For Prolonging Compressor Life – Using Hard Start Kit, Regular Use, Adding Compressor Oil

To prolong the life of an AC compressor, there are a few tips that can be followed:

  • Using a hard start kit during start-up can reduce electricity usage and minimize stress on the compressor. This kit helps the compressor overcome the initial pressure that builds up during start-up, ultimately prolonging its lifespan.
