Why is my McQuay MDB200B2 not cooling properly?
- BBradley JohnsonAug 9, 2025
If your McQuay Air Conditioner is running but not cooling effectively, several factors could be the cause. First, make sure the thermostat isn't set too high; try resetting it. Ensure all doors and windows are completely closed. If these steps don't help, there might be an obstruction blocking the unit's inlet or outlet; remove any objects you find. For issues such as a dirty condenser coil or insufficient refrigerant, it is best to contact your local dealer.
