What to do if my McQuay M4RT is not cooling enough?
If your McQuay Air Conditioner isn't cooling sufficiently, it might be due to a dirty indoor or outdoor coil. Try cleaning the coil. Also check for any obstructions at the air inlet or outlet of the indoor or outdoor unit and remove them. It could also be caused by a refrigerant short charge or leakage, in which case you should add refrigerant and repair the leakage.
