Having problems with your Air Conditioners ?

Air handler squeals

\015 The air handler in my air conditioner squeals. what's wrong?\015

Answers :

Squealing sounds from a forced-air heat pump generally occur when the belt that connects the motor to the fan slips. If the blower is making a grinding noise, shut off the unit and call a heat pump repair technician --the motor's bearings are probably shot.\015\012\015\012In most cases, the belt is improperly aligned or worn and needs replacement. Follow the instructions in your owner?s manual (if you don?t have one, contact the manufacturer and ask for one).\015\012\015\012This job involves removing the access panel, loosening a couple of bolts that hold the blower motor at the proper tension, and realigning or adjusting the belt. In many cases, it?s a good idea to remove it and buy a replacement at the hardware store.\015\012\015\012When reinstalling the belt, be careful not to over-tighten it--this can wear out the motor bearings.
There's no belt in these units. It's probably a warped blower wheel or bent blower housing.

There is a condensate build up in my Trane XP 100 Air handler located in my hot Florida garage.

Is it ok to replace outside unit of central air and heat and not the inside air handler ? The upstairs A/C( over 10 yrs old) is not keeping up with South Texas heat. The temp upstairs climbs to 84-86 degrees by the afternoon and takes 4 or more hours after dark to cool back down. I have cleaned the entire unit outside- no help. I have replaced the downstairs unit 2 yrs. ago and it works fine. I don't want to replace the upstairs air handler if I don't have to---much more cost.
