We have an American Standard Freedom 80 Gas Furnace.It is set on heat at 73 degrees and will only blow cold air throught the vents. We have tried turning off the theromstat and the breaker to the unit and then turning it back on. The little red light flashes fast until the unit kicks on then it flashes twice and it blows cold air into the house. Please help....we are freezing :(

Central air unit problem.......It starts out blowing cold then will only blow room temp air after some time. I don't see anything freezing up..Filter is clear. The unit outside is not clogged up. The copper line running in is getting very hot..
Check your outside unit to see if fan is running. If it is running check to see if air is blowing out if not you have a bad capacitor. Some times if a capacitor shorts out the fan will run backwards and the line will get very hot same as if the fan i ... Air Conditioners

My American Std/Trane heat pump model#WCX036A100BB keeps freezing up at the internal coils & compressor tubes. I had someone out the other day, who topped it off with R22. It wasn't that low, according to him. I have cleaned both the inner coils and the external. It is a package unit, so essentially both are external. But I am referring to the coils that the return air goes through (same compartment as the blower fan). It still blows cold, then freezes after a couple hours of running. Chec

When turn on three eighth pipe freezes up air con does not blow cold air split system i also noticed the compressor is very hot even after the unit has been switched off.

Daewoo DOZ-1206G Brand new, just installed. This replaced an older a.c. unit in our apartment that was not blowing any cold air. The technician said that one was broken and replaced it with this one. Once it was installed, the technician turned it on and left. After 5 minutes with it set at 16 degrees celsius the cool air (which was never freezing) just became normal air. We have tried everything on the controls, we cannot get it to cool our very small studio apartment. We live in Sth Korea by t

My 5000 BTU GE window AC is making sporatic loud popping or cracking sounds when the compressor is on and running. It has stopped blowing air! When I put my hand in front of the air vent I can feel cold air but it is not being projected out like it normally is. Do these units freeze up? What causes it, if so? And how can I check? What can I do to get it working right again? We are burning up! Thank you so very much!

I recently had a new outdoor unit installed on my central heat and air conditioning sytem. I have had the installer out 3 times and the system still does not operate correctly. Sometimes when it cycles (every other time or every third time) the unit does not blow cold air. Sometimes the unit comes on not blowing cold air and the compressor fan is running but not the compressor. Sometimes after 15 minutes of this the compressor will come on. What is the problem.
It sounds like the compressor needs starting components installed on it. All a/c units have a run capacitor for the compressor and another one for the condenser fan motor. These motors use these capacitors all the time when the motor is running. H ... Air Conditioners
I have two Friedrich PDE15KSB-C units. When trying to turn on the heat neither will kick into the heat mode. They both blow cold air only. When they are first turned on the air blows, and there is a click sound as though the unit is trying to start the heat pump, but then nothing really happens...just the fan continues to blow cold air. Any help would be appreciated. BTW the dip sticks are all in the positions of 1234 ON, 5678 OFF - factory setting. I did try to turn 7 on for the emergency
Keep +10 degree from your room temp and also thermostat in "heat" . And then check. But in your case, I think RV not energized. If no proper voltage in RV in heat mode, check the wiring to RV. If voltage in means RV not working properly. You have to ... Friedrich PDE15K3SB Portable Air Conditioner
