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

Water coming into residence, front of ac icing up and doesn't appear to be blowing cold air..


Hi,
The icing up can come from a dirty air filter or from the unit leaking freon and being low on charge...
The other way to freeze it is to try and make the room too cold...
check the filter... don't try to get the room colder then say 70 and if it still freezes then you have a problem...

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.

I have a GE window unit. I do not hear or see any water draining.. and I do not hear any change in the way the unit runs like I used to when it would blow really cold air. The air is cool - but not cold...


May need to wash out the out door coil. Normally spray through rear coil at about a 30 degree angle. try not to spray water directly into fan motor. If unit is freezing up it may be low on freon. if it is real hot out you may need to run 24 hour a day. High indoor humidity will affect its output also. could have weak compressor. check temp drop accross indoor coil. Shoud be 20 - 30 degrees in most cases cooler than room temp.

Central heat and air freezing up


It is not freezing because it's cold outside,It is freezing due to a problem.
It needs to thawed before it will work,

1st:Check or change the filter if need be.
2nd:Make sure none of the vents are blocked off(especially the return)
3rd:The only way to thaw it when temps are low outside,without being out in the weather is to turn on the air conditioner,You will need to use other means to heat your home until it thaws.

and Please if you use the stove for heating,don't fall asleep with it on.

Neither Roof Air Works


Yes and no .. Freezing temps should not affect your A/C at all ... BUT .. there is a freeze control box, its called a control unit to prevent itself from freezing up and burning out, take down the lower cover and you will see it. Your problem is more likely to be more central since neither are working Thermostat or even the control box's in genera, even could be a freon problem if the cold weather was really bad and you could have a leak on your lines, check it out and see what you got!

Home central air conditioning unit


check the filter, make sure it's not plugged. Make sure all the vents are open. Are the lines freezing up (have ice on them?) Could be a lot of things but if it is not blowing much air then you may have a motor problem or dirty filter. If the unit is freezing up then probably have a leak and will need to be found, fixed and recharged.
