Hello, I hope someone could help me.

I have a 4 ton a/c unit: we live in a Mobile Home double wide 32x64, year 2001 Cavco. Our house runs south & north, a/c unit north side. It’s a five bed. Live in Phoenix and a weather alert temp is above 115. We had our a/c service this year, was told everything was OK. Our August bill was almost $500.00. We clean the filter, even had to defrost out coils last month. I've cover windows to make it darker; we use fans in bedrooms living & dining area and keep our temp at 75. Then we started to see a difference in the a/c unit constantly running all the time. The blower is not blowing out hard enough and blowing mild cool air. We keep our thermostat set 75, it’s been reading 80 and the system can’t seem to catch up to cool down. I'm scared to death that there is something really wrong.
Reason is: We had to replace our a/c fan. At that time our compressor shot down it made a popping & crackling noise last year. The color of the compressor was slightly orange instead of black. Could it of burned up part of the compressor?

Sounds like you have correctly diagnosed your problem right there with the compressor. Better bite the bullet now and have it looked at before more damage is done to your unit. Right now you are just wasting electricity and stressing out the unit.

Depending on the roof configuration of your home, have you thought about adding some insulation in the attic for next year's scorcher days? Also, when the temp gets above 100 it is almost impossible to keep your home cool. I keep my summer thermostat at 78 to 80 and I'm okay since I have a ceiling fan in each room to help me feel it is cool.

Thank you.
So do you think it was a/c fan & the compressor turn slightly orange, is what causing us problems now. As mention we had our a/c service this year, would the tech have notice our compressor wasn't working right.
