New central air not working right?

Question

The compressor already went out and we had it replaced, however now it cant seem to get our house cooler than 77. I have noticed that when the air first comes out durring the day it pushes out 77 to 80 degree air for at least 30 minutes. While doing this the temp in the home goes up 1 to 2 degress. It also runs for lond periods. Sometimes 2.5 to 3.5 hours just to get the temp to 77. Also sometimes when the temp reading is 76 (mainly in evening)on the therm. which is where i have it set at it will still comes on. Any help greatly appriciated.

Answer 1

Low on coolant better call the people who put it in. you should have some kind of warranty on it.  I would look at my paper work on it and see what kind of warranty  I have.

Answer 2

Need to call the TECH who installed it back. could be any number of things. GOOD LUCK WITH THAT .

Answer 3

I would call the person who put the compressor in...that way, you shouldnt have to pay again for the service charge.

And ask about the freon being recharged...our thermostat wouldnt go below 78 degrees until we had it recharged...and it ran all the time, too...it never got cool in the house eaither.

We had the freon recharged and now we can keep the thermostat at 77 and it is cold in the house.

Answer 4

None of what you describe is normal behavior for any central air unit.  If it is new, get the installer back to fix it. If he cannot get the manufacturer on the phone.  Do not continue to use it.  If it is malfunctioning continued use can cause greater damage and void the warranty.

Answer 5

it sounds to me like you may have bought a cheap unit or one that is too small for your house.....or.....when you had the compressor replaced, the frion (sp?) wasn't checked and could be low.......or......the house/trailor or whatever you are cooling is not insulated well enough to hold the cooler temperatures in the house.  

While the unit is running, if you hold your hand over a vent and it blows cooler air, but not very cold, then you probably need to have someone charge it with frion(sp?).    If it is blowing cold air, but your house just won't get warm, then it is probably an insulation problem in your home.   The running for long periods could be that unit is running all that it can to get your house cool, but it is either too small for the house or again its the insulation problem.

To get an accurate answer, you will need a heating/air technition of some sort to come and test your unit.  It shouldnt take but just a few minutes to test and shouldnt cost much at all.  some people wont charge at all if they work or live close to you.

I hope that you get this solved and do not get a bad answer like the unit was bad or something and isn't covered under a warranty.  Next time you buy, get a TRAIN.  It is the best brand to get and most if not all heating/ air specialist will or should admit to it.
