Why Is My Heat Pump Running But Not Cooling Properly?

Your heat pump may run but not cool if the thermostat is on Heat or Fan, the filter is clogged, the outdoor unit is iced, or refrigerant is low. Tampa humidity can also clog coils and drains. We provide heat pump repair, maintenance, replacement, and installation.

  • Set thermostat to Cool and Auto.
  • Replace the air filter.
  • Clear debris around the outdoor unit; shut it off if iced.
