Its Giving Off Hot Air
The worst thing to expect form an air conditioner is that it starts making your house hot. If your AC is giving off hot air, it may be due to:
Dirty air filter or external unit
Improper air flow
No Air from Registers
It may happen that the air conditioner is on, but air is not coming out of it. If you are facing this problem, the first thing to do is to make sure that the fan in the AC’s external unit is running. If it’s not then the reason could be as simple as a tripped breaker. Reset it and it is highly likely that your AC will start working properly.
If this doesn’t work out, try replacing the blower belt. But, in case, even this doesn’t resolve the problem, there could an issue with the wiring, control board or wiring.
Fixing a leaky unit is too simple; check the drain pipe and pump system for blockage, leaks and/or debris. If it’s still not fixed, try replacing the pump.
