How to fix poor cooling performance in Blueridge Air Handlers?
- S
  Samantha HamiltonAug 18, 2025
  If your Blueridge Air Handler isn't cooling well, several factors could be the cause. First, ensure that your temperature setting is lower than the ambient room temperature. Next, inspect and clean the heat exchanger on both the indoor and outdoor units if they're dirty. Also, clean the air filter according to the provided instructions. Check for any blockages at the air inlet or outlet of either unit, and remove any obstructions. Ensure all doors and windows are closed to prevent warm air from entering, and reduce heat generated by sunlight by closing windows and curtains. Minimize the number of heat sources in the room, such as computers or electronics. Finally, check for refrigerant leaks and replenish if necessary.

  If your Blueridge Air Handlers unit isn't working, start by checking for a power failure and wait for the power to be restored. Ensure the power is turned on. Replace the fuse if it's burned out. If you're using the remote control, replace the batteries. If the unit has a 3-minute protection feature, wait three minutes after restarting it. Lastly, check if the timer is activated and turn it off.

  Douglas CannonAug 23, 2025
  Your Blueridge Air Handlers unit might not turn on due to a few reasons. The unit has a 3-minute protection feature to prevent overloading, so wait three minutes after restarting the unit. If you have a Cooling and Heating Model, and the Operation light and PRE-DEF indicators are lit, the outdoor temperature might be too cold, activating the unit’s defrost cycle.

Why does my Blueridge Air Handlers unit change from COOL/HEAT mode to FAN mode?

  Scott HillAug 31, 2025
  Your Blueridge Air Handlers unit may switch to FAN mode to prevent frost from forming. Alternatively, the set temperature may have been reached, causing the compressor to turn off. The unit will resume normal operation when the temperature fluctuates again.

Why is my Blueridge BM12MCD indoor unit making noises?
- R
  Rebecca Davis PhDSep 5, 2025
  Your Blueridge Air Handlers indoor unit might be making noises for several reasons. A rushing air sound may occur when the louver resets its position. A squeaking sound might be heard when the system is OFF or in COOL mode, or when the drain pump (optional) is in operation. Also, a squeaking sound may occur after running the unit in HEAT mode due to expansion and contraction of the unit’s plastic parts.

Why are my Blueridge Air Handlers indoor and outdoor units making noises?
- J
  Jay TrevinoSep 7, 2025
  The indoor and outdoor units of your Blueridge Air Handlers may produce a low hissing sound during operation, which is normal due to refrigerant gas flowing through them. A similar sound may occur when the system starts, stops, or is defrosting, caused by the refrigerant gas stopping or changing direction. Squeaking sounds can also occur due to the normal expansion and contraction of plastic and metal parts caused by temperature changes during operation.
