Question about Heating & Cooling

1 Answer

No cold air coming from the registers.

It is a central air unit. The fan blows on the outside unit. Air is coming from the registers, but it is not cold air, and the house remains the same temperature regardless of the thermostat setting.

    Can you tell if the compressor is running in the outside unit?

    Is there ice on the larger copper line?

  • Dennis Boxerman May 11, 2010

    How about a model and serial number of the outside unit?

Ac fan on, blowing air, but not cold


Check outside unit if unit and compressor are running feel the large line to see if it is cold. If compressor is running and line is not cold possible charge problems. You may have a capacitor problem outside. they go out quite often. You can change this yourself, Open up outside unit and the cap is the silver bullet with terminals out the top. Bad cap can cause compressor to not operate and also the fan. You need to clean the coil inside or at leat check the coil to see if it is clean. You can clean theis with a toilet brush do not go against the coil bit brush with the fins. You may need to call a service tech but try these options first. russ

Central air unit only blows warm air , when set on cold


First check to see if your outside unit is working and you can here the compressor running. If the fan runs and the compressor does not you have a problem with the capacitor or wires burnt off terminals. If your not sure you know how to work on this please call a service tech ask for free estimate. If the unit compressor and fan runs you may be out of gas that meanns you have a leak. Either way you need a service tech. You can only go so far without the correct tools to work with. Russ

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 is not running. Russ

My AC unit wont blow the cold air.


if the ac outside is working, but not the furnace, means there is a control problem with the furnace, check wires in the furnace, make sure there is a blower wire plugged into the contact marked cool on the control panel of the furnace
