Why is my innovair Air Handler not cooling properly?

  Donald SmithAug 7, 2025
  If your innovair Air Handler isn't cooling well, it could be due to several reasons. First, ensure the temperature setting is lower than the room temperature. Check if the heat exchanger on either the indoor or outdoor unit is dirty and clean it if necessary. Also, make sure that all doors and windows are closed while the unit is operating to prevent heat from sunlight, and reduce the amount of heat sources in the room. Finally, low refrigerant could be the cause, so check for leaks, re-seal if necessary, and top off the refrigerant.

  If your innovair Air Handler isn't working, first, wait for the power to be restored in case of a power failure. If the power is off, turn it on. Check if the fuse is burned out and replace it if needed. If the unit’s 3-minute protection has been activated, wait three minutes after restarting it. Also, ensure the timer is off. If cold air is entering through doors and windows, make sure they are closed during use. If the unit starts and stops frequently, or there is low refrigerant, check for leaks, re-seal if necessary and top off refrigerant.

  To improve poor cooling performance of your innovair Air Handlers, start by lowering the temperature setting. If that doesn't work, consider these steps: * Clean the heat exchanger on the indoor or outdoor unit. * Turn the unit off, remove any obstruction from the air inlet or outlet, and then turn it back on. * Close all doors and windows. * Close windows and curtains to reduce heat from sunlight. * Reduce the number of heat sources in the room. * Check for refrigerant leaks and add refrigerant if needed.
