We purchased our home two weeks ago and have a problem with the central AC. It will not turn on. When we did get it to turn on it ran for 15 seconds and caused the circuit breaker to turn off. Is there a quick solution or do I need to have someone come in and repair it? This is a Honeywell heating and cooling unit. We changed the batteries in the wall control panel and that did not help. We live in West Milford. What should we do? Thanks, Mary


It sounds like the compressor is pulling high amps causing the tripped breaker. It could be caused by a weak compressor. This can sometimes be handled with a super start capacitor. This can reduce the amount of start up amperage. I suggest that a lic ... Honeywell Air Conditioners

Hello, my heat pump is a 4 ton unit, it heats ok but it keeps tripping one of the breakers, the 40 amp cooling breaker.

AC Condenser motor will stop at 1pm but inside unit is still running but no AC. If I turn the AC unit breaker unit off and then an hour later turn it back on. The unit runs fine all day until 1pm. Had a tech out and he checked the system and it's fine. He said I may have a thermostat problem and he would need to see the manual. My theromastat is programable (Carrier, 4 zone, Comfort II) with 3 remote temp sensors. How do I troubleshoot this?

Breaker breaks When my Dometic roof a/c compressor comes on during a regular cycle, it sometimes pops the breaker. I replaced the breaker but think there must be some sort of timer in the unit that allows some time to go by before the compressor comes back on. If I reset the breaker and turn the unit back on immediately, it pops again. If I wait about 5 minutes it will run ok. The amps are ok. Help.


This unit may have an internal overload mounted on top of the compressor. You would have to get to the\015\012compressor to find out and it maybe faulty. That may\015\012explain why the compressor comes on later on, this\015\012over ... Dometic Rooftop RV Air Conditioner

We need to know where the main drain is located on our unit or how to access it so it can be opened and cleaned.

Unfortunately, if you're elderly and sick, you'll need to get the serviceman back to unclog it for you. As it will require crawling on your hands and knees, to access the main drain and then running an auger or high pressure air into the main drain l ... Air Conditioners

I have a Mastercool II airconditioner, which is approximately 5 - 7 yrs old. Water has been overflowig from the unit. I believe the float probably needs to be replaced.
