Does cleaning condenser coils help?
Surprisingly, we found that dirty air conditioner condensers often perform better than clean ones. The change in condenser coil heat transfer performance ranged from a 7 percent increase to a 7 percent decrease for the coils we tested. Most of the condenser coils we tested in the lab were cleaner than both of those.
