My central air conditioner is a Trane XE1000. During these hot days the temps sometimes run mid 80's to low 90's outside. My unit is almost running constantly and I have it set at 72 degrees. What should the temperature be coming out of the ducts at the floor level. I took a laser temperature and it was running in the mid to high 50s but yet the unit is running like crazy and in my opinion not cooling the house like it should. Last week when it was in the low 90's the house was a balmy 77 degrees inside only getting to the set 72 later that night. Is this normal or should I have it checked??

All of a sudden my central air conditioner stopped working and its been over a 100 degrees the last couple of days so needless to say I am having heat stroke. It was working fine the night before and now the fan will not turn. I flipped the breakers thinking maybe that would do the trick but nothing. I then took a ruler and turned the fan manually and it started turning but kept making a clicking noise and then would make a humming noise. At the same time there was no cold air coming out. The top plate above the motor got so hot you couldn't touch it. Then the fan just stopped again and I couldn't get it to turn anymore. Any ideas?

I recently built a deck and left about 12 inches of clearance over the vertical fan on my central air conditioner. Have I made a mistake and increased the chances that the air condition will not run properly. Any suggestions, beyond moving the unit, that I can do to make sure the unit still runs like it should.

The verdict is in, my last idea according to all of you is never going to work. I have a Rheem central air conditioner. Need to clean out the evaperator coils. Accessing the underside of them is nearly impossible. There is a huge metal flange covering the side of the case that is intertwined with the coild themselves. Under it is the furnace which I am not comfy with disconnecting the gas lines to even though I shut the gas off for the summer. I cannot slide the case out without bending the refridgerant lines. My question, if I can open the access point ABOVE the coils can I take a garden hose (with the power off, obviously) and spray out the coils from the top down then wait a few hours for it to dry?
