you will need a thermometer, you can use a meat therm.take a temp reading of the air going into the return and then coming out of the supply at the unit, it should be at least 15 to 20 degrees cooler in the supply, if not it may be low on refrigerant also check filter and return duct make sure your not pulling air from attic

I'm willing to bet a relay burned up. You likely have your tstat set to auto changeover, meaning it automatically goes from heat to cool to maintain desired set points??

My ac in my 2006 saturn ion blows cold air when its under 80 degrees outside but when its over 80 degrees it will blow warm air sometimes and cold sometimes what could be wrong with it


You likely need to charge the AC with freon. If it has been a year or three since you've had it checked, it is probably low on freon and needing to have some added.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

What are the pressures?And the low side line going into the firewall should be cold.We need to know what the pressures are,and is the evaporator sweating>and giving off condensation?If the vents are blowing out 80 degrees,then the temp door is not moving .It is either a door actuator motor,or a vacuum that is not working the temp door,check for a bad vacuum under the hood,going into the firewall.

REPLACED BOTH ELEMENTS GOT HOT WATER FOR 1 SHOW THEN IT GOT COOLER AND COOLER AND NOW ITS COLD ONLY?


Find a reputable HVAC contractor to do a room by room analysis with heat and cooling loads calculated and units sized and duct requirements and compare to what you have.

The air not being cold is not necessarily an indicator of anything malfunctioning. High efficiency units for instance don't produce cold air.

Since you have had someone look at it, the duct work may be collapsed which restricts air flow or uninsulated which warms up the supply air. Either one is a possibility. Any Cox Cable guys been stompin' around your attic lately? Wouldn't be the first time.

Usually, when the air coming out of the vents is not cold enuf it's because your freon level is low. Probably leaking, but they can usually recharge the freon and it will work for a while. Try another repair company and see if they can recheck the freon level.

We have a high efficiency unit and it produces cold air, so I don't know what previous poster is referring to. Air conditioners are supposed to blow cold air.

Sorry, to tell ya but it is normal if the outdoor temperatures are much below 45 degrees. Below 45 degrees there is little heat outdoors for the heat pump to grab to heat the home so it will run 24/7 and blow cool or cold air. Below 45 the temp of the air coming out the vent will decline and you will get no heat from the heat pump itself as you near freezing.

Your emergency heat or auxiliary heat is electric strip heat. But it only kicks in during normal operation if the temp in the house drops 3 degrees below the setting. (some tstats if can be 5 deg.) Otherwise the heat pump will blow cool or cold air the rest of the time if it is too cold out.

To prevent it from running all the time and blowing cold it is recommended if the temp outside is falling below 45 degrees you should just switch to the emergency heat setting, which shuts the pump outdoors off, and just heat with the electric.

But if there is no heat outside the heat pumps will blow cold. They are the cheapest and most efficient forms of heat but only as long as the outdoor temp is above that 45 deg..

I'm guessing that if you haven't experienced this you live in some place with moderate winter temperatures like in Northern Florida and rarely get very cold winter temps like the freezing you have seen there recently.

It will likely blow much warmer when the outdoor temp rises.

Air Conditioner stops blowing cold air when vehicle is not moving


plus one on the cooling fan problem. if it was low on charge then as you slow down, condensor temps and line prressures would raise therefore it would cool at low speed and and not when moving since the incoming air would drop system temp,reducing line pressure and then cusing compressor to cycle. the auxillary cooling fans must be on whenever a/c is on, if not, thats your problem. get this taken care of because if you get stuck in traffic, your engine will overheat also if fans are not running

What should the supply air temp be on a home a/c system? we cannot get the temp in the house below 80 degrees when the outside temp is above 90. the home is in Alabama. the supply air temp is 66 degrees.


should be more like 58F depending on the the house temp 20 deg. difference from supply air and return. unit is probably dirty and or low on freon. Tom

No warm air only cold with setting at 80 degrees or higher.


There thermostat is bad. If you pull off your front cover there schould be four screws. The thermostat is on the coil itself. Take that to the local appliance store and they should be able to give you a replacement part. Part is around 35 dollars or so
