Change the furnace filter. Make sure you use a cheap one when air conditioning, as the better ones restrict airflow when they filter out so much stuff and then plug up, not allowing enough air to pass over the cooling coil in the furnace's air plenum. Turn the A/C off for a few hours (with only the furnace fan on if possible) to melt the ice off the cooling unit inside the furnace.

My central air unit comes on but it's not cool and


to me it sounds like filter are dirty, need to be cleaned or replaced, home systems, packaged or otherwise are hermetically sealed and should not need freon recharge. Always start with airflow and/or unit being set too low. An AC unit of any type will build ice if a) the filter is plugged up and can't move enough air, b) it has been run without the filter, clogging the coil, again, not moving enough air, c) setting an AC unit below 68 degrees F will almost ALWAYS cause icing, and d) running a standard AC when it's warm inside and cold outside (unless equipped for "low-ambient operation"). When in doubt, a bit of maintenance(thorough cleaning) by someone with AC skills can cure a b, common sense will cure c d.

Goodman central air conditioner not blowing normally


It sounds like the compressor is not coming on in the outside unit. If it worked fine and was cooling before, then your compressor probably over-heated and tripped the internal overload switch which causes it to stay off while everything else is working. The most common cause of your compressor over heating is an incorrect refrigerant charge, though it could be a few other things like a restriction in the copper line set. You will be able to hear the fan motor and the compressor kick on if you listen close while the system first turns on. If the compressor is over-heated, then after it cools to a save temperature, it will come on again, but only till it over-heats again. I would have the charge checked on the system, but remember that if the compressor is over-heated when the technician gets there, there is nothing he can do until it cools down and time is money! It's best to not run it until the problem gets figured out. Hope this helps and points you in the right direction. Good luck!

Why would cool air be blowing out of my central ac unit condensor that sits outside? The other unit I have next to it blows out warm air and responds well to thermostat changes. The unit blowing cool air...


It probably has a low refrigerant charge. The air coming out of the outside unit should be warmer than the outdoor temperature when in the cooling mode and if it's a heat pump it should be colder than the outdoor temperature in the the heating mode. Check the big line going to the unit, it should be somewhere around the 40 F range and the small line should be hot.

Room temperature reads 95-99 degrees F, not cooling the room


one hose is the heated condensing air and one hose is the intake air. if this unit is not working correctly and u just purchased it take it back. if the landlord will replace it tell them. do not call a service tech to check this unit out if u know 4 sure the temp is set right and it continues to blow hot and the exhaust hose blows outside and the unit is set to cool you are money ahead to replace it. hopefully a landlord or recent purchase can bail you, you can find these units at home depot lowes and get them 4 about 400 dollars. hopefully it's covered somehow by warranty or landlord but the cost for checkout and service will exceed the cost for replacement. have you tried to unplug the unit leave it unplugged and try again. have u cleaned the filter. have you noticed ice anywhere. maybe a light that tells you the drain is plugged i don't wan't to get you're hopes down when you are burning up but check these things and let me know if u see any abnormalities. do you leave the unit running in hopes that you will come home and it works? check for ice is there air blowing constantly? if u dont get air flow you could have a fan thats out or its iced up. let me know.

My air conditioning unit is not blowing as cold as it did, nor is it blowing as hot as it did in the heating mode


90 percent of the time the freon charge is low and lack of freon lessens the amount of compressed heat that can be created and also the amount of heat that can be extracted. hence less cooling and less heating. however the exact same thing can occur when a change over valve gets stuck partially between heat and cool . it then mixes the hot and cold together and you get poor cooling and poor heating. you check it with a gage. fed law requires that you have an epa certification to apply a gage. low pressures in heat and cool on both high and low pressure gages are a sign of low charge. if low pressure and high pressure are close to the same on both gages then a good chance valve is stuck half way between. you can also sometimes check by feel . at the change over valve two lines should be virtually to hot to touch and two should be cold to the touch. one is heating flow and other is cooling flow. if the valve is stuck then temps will be within a few degrees of the same on all. low charge and the hot lines won't be hot hardly .and the cold line s barely cool. look for white frost forming in the heat mode outside at the condensor tubing shortly after you turn on the heat. thats a sign of low charge. good luck.

Air Conditioning Unit is leaking badly, has mold and ice.


soundls like the condensate drain is clogged and coil is dirty. look for a plastic pipe inlet where water would flow to.. you may be able to clear it by blowing it out with compressed air. you can also pour bleach into it to address the mold problem. if the coil is icing up it is because it is dirty. to verify this, let the unit run in ac mode for about an hour and check to see if you have air flow from the vents. if you do not, then the cooling coil is covered in ice, thus blocking air flow. you should have a qualified ac person clean the coil and check the refrigerant charge on the unit. one thing to consider, change your ac filter often, at least once a month in hot weather.
