Furnace blowing warm air, ac overheats

SOURCE: (HVAC) Furnace Not Igniting Quickly

Make sure a back draft in the flue is not happening. Wind can blow it out until the flue heats up. The flame sensor may not be close enough to the burner flame. It may be weak and need to be replaced or if its an optical one it may be dirty and not see the flame very well. Its not wasting much gas but it puts extra wear and tear on the gas controls, is noisy, and, as you said, blows cold drafty air. A gas control system that has issues of any kind is not real safe. It needs to get fixed.

SOURCE: AC will not cool. How much should a service charge cost?

If the upstairs is working and the down stairs is not,You only need to have one unit checked,Don't assume it just needs puron(If it does,You have a leak,which cost more to locate and repair than some other likely causes)This is not something you can do yourself and is illegal if you are not EPA certified.to get a fair price would depend on your geographic location and the best way would be to call around to some local heating and air companies and ask how much a service call is.(That only tells you the price for them to came and see what the problem is,They will not be able to quote a price until they know what must be done to make the repairs.

I hope this has answered all your questions.

Please take time to rate this fixya

SOURCE: Compressor kicks out and it's new

First of all, clean your outside coils so that you are assured of good cooling air. The compressors have an overtemp device that is usually internal to protect them against heat. If you have an air compressor use it to blow out the coils good. If the compressor will start, the capacitor is good so it sounds like a cooling problem with the compressor

SOURCE: I have a three year old Goodman Furnac /AC unit

i would first look at all the wires and make sure the insulation has not rubbed off somewhere and causing a short, after that it means one component is failing and requires special tools and testing that should be done bu expert who has those tools and info, hope u find a short and save some money good luck!!

SOURCE: AC not cooling during the day

Your AC cooling efficiency is low when he ambient temperature is high and naturally it cools well when the outside temperature drops.

Please remove the filter on the grill and try to clean it under the tap water and after removing all the dust fix it back to the unit. This would increase the cooling efficiency of the unit.

Your AC is also five years old. Please avoid frequent opening of doors or windows.

Ensure that the exhaust fan and the blower of your unit are functioning normal.

The technician might not have done a proper job in fixing the area where the refrigerant would have leaked out. Please check the refrigerant pressure to ensure that no further refrigerant leak has taken place. Or even servicing your unit he would have punchered the tubes resulting in very slow leak of refrigerant resulting in no cooling or less cooling. It takes around a month to feel the pinch of it and the refrigerant. One fine morning after sometime the unit will run and it would start throwing hot air instead of cool breeze!
