My air is running but it won't go below 74. It is set at 67, anything I can do to fix it? Also, should you cover your AC unit in the winter when not in use? If so, why? Thanks!
If this is central air, you should never set the temp below 70. Doing so can cause the coils to freeze. You really should not need much lower than 72. You can check to see that your filters are clean and dust free. Beyond that you will probably want to get a professional assesment.
You won't know if you can do something if you don't try.
Semper Fi....I am going through the proces of bids for new system due to about the same problem...just not cooling to my comfort. try cleaning the coil (if you can get to it) also check temp coming in from register then going out through air return vent. should not be more than 20 degrees 14 - 20 OK range. Also check fan to see if dirty. As for covering unit, no real reason other than to protect it to help last a little longer. Good luck!
Ok, first off, do you have enough insulation in the walls and ceilings? Most of the heat will come from the ceilings and if there isnt sufficient insulation up there your wasting good money after bad...
Having no insulation in the walls, well, its like opening a window and asking for trouble because mold can start from the cold and heat coming together (especially in closets) and can cover walls on the outside or inside! Brick homes with old style aluminum windows are a real pain because you get mold under those rascals a lot and I've lived in enough places to know sheesh!
Now, you should only 'ideally' keep the room temperature 10 degrees from what it is outside, (What my HVAC Expert told me, but being a heart patient, if its 100 outside I dont want it only being 90 indoors!). Drill a small hole in your plenum 1/4 inch and insert a digital thermometer. Then drill one further down the cold air return and the heat/cold ducts and see how much of a temperature difference you have from the plenum to the duct works there is, then let your HVAC man/woman know about this and see what they say.
You 'could' insulate the pipes so that if its in the basement, you will not lose cooling upstairs... Or, if you have a 2 storied house, and your not getting enough 'cold air' upstairs, then you may have to put an additional 'fan' in the airduct leading to the upstairs or the furthest reaches of the house that isnt getting enough cold air from the registers.
Cover the A/C in the Winter only if you have heavy snows, so that the fan blades outside wont warp and bend under the load of snow.
Only cover it halfway down as you dont want to have it covered all the way and let things 'grow' in there like mold, mildew from moisture that may accumulate, or leaves and other debris that may get in there and decompose.
As an added note:
Make sure your squirrel cage is clean!! The squirrel cage is located in the furnace and if that is dirty, then you will NOT get the air flow that you would expect from a clean one. A simple garden hose and a brush, with a wet and dry vac will clean this out in a jiffy-->Provided its an older type of furnace, a newer one, and you may have to take other measures to keep it clean or have it serviced.
Hi, I do not know if you have had the A/C looked at, but I was reading some of the replies you received and do not agree with some of them. I have been doing HVAC work for the Pipefitters for about 14 years now. To find the problem, one need to put gages on the system to see what is going on with the system. But, by what you wrote, it may be just low on refrigerant, you need to put gages on the system to tell for sure. I hope this helps David.

i agree diyer put gages on it and have it ck out. also ck sq footage of house x the tonage of the unit you have. i bought a house and the ac company put a unit that was 1 ton to small. they didn't take into consideration 10 ft ceilings. it would not go below 75
