Well, a second tech came out to my house and looked at the unit. He did some
checks on the pressure and found one low and one high so he added some freon
to maybe flush out a blockage. Then he rechecked the system with the new
freon and declared it fixed. As he was packing up the compressor stopped. He
said that he could tell the temperature of the compressor by the pressure in
psi and that there was a conversion on the guage to shoe how hot the
compressor was. I don't get that at all. I've never heard of a pressure to
temperature conversion table/convertor. He called in and got instructions on
what to do and took the fan off and did something and said the senior tech
would have to come out. He didn't leave a bill but the owner's wife called
and said I owed them $70 plus freon. Nice people but I doubt that the tech
was experienced and she said that putting freon in the system was not a
treatment for blockage of the lines. She also said that he should not have
quoted me $1500 for a new compressor 700 for the compressor and 800 for 4
hours of labor. I'm afraid to stiff them for the service call because they
know where I live but I don't think I got much more than a sweaty shirt from
sitting out in ths sun watching and hour of wasted time.
