Hi Robert,

I have a problem with my residential AC system. In the air handler the fan is working but there is no coolant coming out of the system. I went to the condenser and checked the high voltage and the low voltage but the low 24 voltage is not working. But the fan on the condenser is not turning on unless I press the switch on the contactor. What can be the possible issues with the system?

Marcel – check the transformer should have 24 coming out of it

Christina – either clogged drain, broken drain pan, undersized ducts, etc, could be alot of things best to call service tech.

Mitch – is the filter or evap coils clogged? bad blower motor or cap for motor? Could be several things…

Doug – I work for a big company and there are dozens of senior techs that know just about everything…so I always got someone to help, smaller companies usually just rig the equipment to work or rig it to work temporarily..residential is easy commercial and refrigeration gets tricky for me ….

I have central A.C. and the outside motor is blowing but the inside air isn’t blowing. Your help would be greatly appreciated. Thanks Mitch.

My A/C (inside) is dripping water outside of the pan and my filter is soaked. What is causing this? I have researched to no avail.

I have a Gibson central unit, I have just changed the condensor fan motor and for some reason I do not have the 24 volt control power.
I have checked incoming power at the contactor and have L1 to ground 123, L2 to ground 123, L1 to L2 244 vac. There is no 24 v at the t-stat terminals on the circuit board.
