Ferrels technichian came to check my moms unit for not cooling properly. He checked inside and quicklly made his way outside where the compressor was running and removed the cover and condensor. in about two minutes he claimed the contactor, condensor, wires and breaker were burnt up and we were already at $540 and that was not counting freon. I had to leave my mother who is 79 years old to go to work . He told her she needed a compressor it would cost $1950 and she credited him the $950. When i got off the outside compressor unit would no longer run because the wiring had been tampered with. Never trust these guys my friend came and made repairs for $110 replaced breaker that had wires pulled out added freon. only saving her $1850 for the new unneeded compressor. Disgusting targeting older people with problems to overcharge and exaggerate service charges. I would reccommend you find some one honest to do your work unless you just want to give money away.
