Most likely. You just need add Freon. Real easy an cheap fix. If your Freon is full and your AC still not working. Probably gonna be your AC pump. That's not a cheap fix.
You may need to have your AC charged
the compressor is not running. Check your breakers.
Well, its a hard quiestion, but to be truthful, there is no cure haha
you may be low on freon and jsut need a good charge of R134a
please i need a help my ac keep blowing bhot and cool i have check and refill it but i still get the hot and cool air in stead off cool air
There may be a stuck vent door or an issue with the heater blower control head.
Yes. Since cool air tends to concentrate at lower elevations, leaving basement windows open will result in considerable wasted electricity. While the AC may not be blowing into them, warmer air from outside will convect into the basement, mixing with the colder air and pushing colder air out.
Turn it on high
Kinda, but it'd be real inefficent and expensive. Think about it: at one end of the room you have the AC making cold air. At the other end you have the fan, blowing that cold air out of the room. Means the AC has to take in new warm air from the outside and cool it. You're better off having a large portion of the air in the room recirculating. That way the AC doesn't have to work that hard.
Your engine is hot.
a long time
The AC isn't working.
