Some homeowners don’t know how important it is to clean and maintain their air conditioner. However, routine maintenance can both improve the efficiency of your air conditioner and extend its lifespan. Kauai Air Conditioning & Refrigeration, an HVAC contractor based in Kapaa, HI, shares a few useful maintenance tips for your AC unit. 

Top 3 Air Conditioning Maintenance Tips 

1. Clean the Evaporator Coil

An air conditioner's evaporator coil is responsible for absorbing heat from the surrounding air and releasing it outside. As such, it's a critical component of any effective AC unit. Owners should clean the evaporator coil—which collects dirt and dust over time—at least once a year, ideally in the spring before another season of heavy use. For more extensive evaporator coil maintenance, consult your local HVAC contractor. 

HVAC Contractor2. Replace Filters

No part of an air conditioner gets filthier than the air filter. Filters collect dirt, grime, and other air contaminants. In addition to producing less clean air, over time these pollutants stifle air flow, decreasing the efficiency of the unit. These filters should be cleaned at least once or twice a year—though users should consider a full replacement annually to improve the energy efficiency of their appliance. 

3. Fill Window Gaps

When installing air conditioners, owners should make sure they fit snugly into the window frame. Move the AC unit's plastic fins out accordingly, making sure to minimize any gaps between the frame and the air conditioner. This will keep the warm air outside and improve your unit’s energy efficiency.
