Having problems with your Air Conditioners ?
Indoor unit freezing up
The coil probably needs to be pulled and cleaned with a power washer. Usually what happens is the coil becomes dirty over time and when the filter starts to get dirty as well, it will cause the unit to free up. Also it could also be a little low on refrigerant and when the temps change, it can cause the coil to freeze up. But I bet it is in need of a good tune up and coil cleaning.

Indoor unit freezes up, turn the mode button to the fan only to thaw out the indoor unit but the outdoor unit runs, What should I look for?

I have been working on a Goodman Heat pump. The indoor coil keeps freezing. Outdoor temp is 70F and indoor is 78F. It has a brand new air filter. My superheat is 2F and subcooling is 10F.

Hi there, I have two Fujitsu DC Inverter split units to heat my flat (england). The temperatures have dropped significantly -2 and below. This causes the outlet pipes to freeze up and when the units are on defrost the excess water gushes out of all other joints in the units. This causes two problems - the units are wall mounted one on top of the other, so the top unit freezes the bottom unit. The second problem is the bottom unit 'dumps' in on the floor of the area which when defrosted s

Several years ago I purchased 2 Split-Type Room Air Conditioners--Models RSW-17 (Indoor Unit)/ROW-17 (Outdoor Unit) and RSW-12S (Indoor Unit)/ROW-12S (Outdoor Unit). The airconditioners themselves are fine, however,the Remote Controls for both these units, Model AR-DJ15, have gone bad and may not be repairable. How/where can I purchase replacement remote units?

In freezing weather the heat pump efficiency drops. The freezing is normal. The equipment has a board and sensor to defrost your heat pump. Now this system can fail but freezing rain and snow get pulled into the unit get pulled into the unit coil and ... Goodman Air Conditioners

Hi ...we have a split fujitsu air con for just over 5 years. The compressor in the outdoor unit is not starting up and the indoor unit blows ambient air. The operation light is lit and the timer light is continuously flashing when in use. Have reset the breaker and the units and also the remote to no avail. Can't find any info on the net or in the manual. Any tech help most appreciated. (Also doesn't seem to be a auto/manual reset buttn as such in the indoor unit)
There is a relay that the thermostat pulls in, in the unit outside. When this happens, the compressor pulls in and the unit outside will run. The compressor has to run before the unit will cool. ... Fujitsu 24C1 Air Conditioner
