One Hour AC has been out several times - we are pleased with their service and honesty. They have never tried to rip us off. On the flip side, they have offered us way to save. They are professional and explain their services very well.
Lived in Charlotte years ago and used Dan King and was very satisfied. Moved back and for 2 years have used them again. Most recent contact with Charles was excellent. Though my units are 12 years old and they could be blind siding me with bogus stuff, they keep things running, they are prompt when I call, they don't drag things into the house that don't belong and I've been very happy with their service.
