Unfortunately if the shop and installer do not work together - you might have a finger point - if the unit is bad the installer will want money again to install another unit.Okay! The liquid line is full of high-pressure liquid refrigerant. The vents may not be blowing warm air, but the air does not seem as cool as it should be given the temperature setting.

The refrigeration system is a low temperature freezer with a receiver and a TXV. Contact the installer first. Featured on Meta Is the power system there a single voltage ~230 V? After it went to the compressor and through the CONDENSER the liquid line heading to the evaporator was cool to the touch, 10-20 degrees below air temp. you should have hot air blowing out the top as the fan extracts the heat from the line. From the first day of installation I never got the expected cold air from the indoor unit I asked the mechanic/ fitter why is it taking this long as it was first time for me but they said it will take a little long time for the initial start to blow the cold air from the indoor unit and they left and took the payment and I kept waiting for more than two and half hours for getting the cold air from the indoor unit but didn't got any cold air then I started diagnosing from my side I set the mode to fan and then cool to check if the temperature of the blown air has any difference in the two different modes which it should be but surprisingly the blown air are of same temperature in both mode then I tried to get more information about the ac parts and figured out about the liquid line and suction line. feet. Does the air blow out of the condenser hot like your neighbor's ?

Start here for a quick overview of the site my liquid lines are typically only slightly warmer than ambient. The liquid line going to the house being hot is a sign of either a dirty outdoor unit coil or the outdoor fan not turning. Sounds good. Restricted condenser coil or Liquid line dryer, if it is installed inside of the condenser. I just don't know what to check next. Could be orifice valve, compressor, poor charge , bad fan any myriad really as there is not enough information to properly diagnose it.Is this unit an a/c only or is it a "heat pump" which can heat in winter? I have changed the filter dryer, vacumed, and I opened the txv inside the cased coil. We totally understand, so here to help are 3 signs that point to low refrigerant. Then, all bets are off. This is an all in one unit. The return pipe is warm because the heat exchanger outside can't wring all the heat out of it. Many service technicians often become confused when the liquid line becomes restricted in the refrigeration system. If the unit is keeping the proper temps and everything seems in order I wouldn't mess with it. I have sucked the refrigerant back, and vacumed 3-4 times, but the liquid line stays cold and the suction line stays warm. the liquid line is high pressure not high heat. Learn more about hiring developers or posting ads with us the heat difference from the compressor line and the liquid line is what blows in your face....if it is little above ambient on a 90F day your condenser is clean But before you call a Lawton, OK professional for help, of course, you want to be absolutely sure you have this problem.
