Sounds like you have either a low refrigerant situation or an airflow problem. The lack of cold air is most likely due to a frozen up evaporator coil. You should check your filters and call your service man.

My central air AC unit (Double wide home) always works for generally up to two hours, then it freezes up, by the copper pipes ice over, shutting them off and letting them thaw out, works to get it going...


You are absolutely right! The copper pipes should have insulation them. When they don't and they get cold in hot weather, they sweat and then freeze. Tubular Foam Insulation is what you need. Most home centers carry it. Once you cut and install it, be sure to wrap it in a good quality Duct Tape.

Hope this helped you. Good luck.

My central air conditioner is making a whistling noise in the inside unit when the compressor is running. It's not the blower because the noise stops after the outdoor unit shuts off. It's also not blowing...


Hello,
If there is no cooling (meaning no cold pipes and not blowing cold air) then check the outdoor A/C for any visible/obvious issues; breakers not tripped, no debris blocking the outside unit from passing air through it, etc. If all looks ok, you can start checking some things inside of the unit if you feel comfortable doing so. Also, most indoor heaters have a higher speed/rpm for the fan when the cooling kicks on, and the heat runs on a lower speed/rpm.

Hope this helps James

Frozen pipes coming from my outside heat pump and going to my inside unit


Frozen in suction line (bigger pipe) line due to indoor coil,airfilter and blower wheel dust blocked. Service the unit.
Second reason is short of gas. -Find out the leak and arrest it. And then do gas charging after vacuuming.

Hi there,any advice please on frozen pipes..no water at all,no toilet,shower..can i use my central heating?...im forozen..


You will need to get to the pipes with a torch or heat gun and melt the ice out allot of times when the pipes thaw out you may have busted pipes with long cracks running down the pipe. The best way to handle this is to turn off the water to your house and inspect the pipes I would go and purchase some heat tape and cover all the pipes in exposed areas (crawl space, attic, and basement) and let the heat tape thaw out the pipes. after about an hour turn off all your inside valves ( tubes, shower, sinks and the cold water to the water heater) then turn your water back on and watch the meter at the street if it spins then you may have busted pipes.

1- Turn off water at the meter by the street.
2- Thaw out pipes with torch or use the heat tape.
3- Close all valves in house including cold water valve at the water heater.
4- Turn water back on at meter and mark on the meter where the hand is now then watch to see if the meter is turning.


The heat tape will keep you from freezing pipes in the future.


Hope this helps..............

Hi have central air . Unit working ok but noticed not blowing cold air . The fan outside is working , Unit comes on . Could it be feron . unit it about 7 years old . Purchase house about 4 years ago


You need to have a pressure gauge the reads for R-22. (Freon) It sounds like the system might have a leak. Look for a wet place any place on the units pipe system. It has a little oil in with the freon that is forced out of any leak. If you see a wet place this is oil. It is also the location of your leak.

AC is running but can't keep the temp down. Everything is brand new. AC unit is on shady side. New filter, no cloggs. No clog in drip pipe. Condinsation building up on pipes outside. Please help.


If the big pipe out side is cold and sweating and the little one is warm to touch if it is hot to touch under charged. I would suspect insulation, or under sized unit
is their a 20f difference from supply air to return air the i would lean towards insulation. Tom
