No one else would call this standard or acceptable work, period.

And my two hour window arrived and NO ONE SHOWED. I finally called and now the second time, "oh yeah they won't be there today." - I mean. Could you at least have the decency to CALL or text or (?!) the customer?!!! If you need someone to fix/maintain/etc your systems THESE ARE NOT THE PEOPLE. They don't even have the courtesy to call. Just. Cannot believe any positive reviews on this are legit. Honestly don't know how they remain in business when they fail to even show up.

The next encounter they repair the vents in my house and did a good job. I think it costs about 1/3 more than a local as they charge drive time. This time I asked for a bid on vent to be placed. they came out a did a bid. I told them I could not pay drive time and they said they would come over when they were in the area. I get a call saying They will be there on Friday. They show up but do not have any materials or the wrong invoice which says do a repair. so the guy says he will be back. Never came back. When I called I said I cannot pay for the drive time and the secretary says. well" we are charging you for it." So I told them to forget it. Then I get this call form some one he says" I hear you want us to do work for free" I said I never said that but he hangs up the phone. so much for any professional ism what so ever. He just called me to give me more sh)t Forget them. They are uneven and over priced

I was right to stick with the new owners, of course they would have sold it to good people. My A/C unit went out and I had to replace everything on a Friday of course. The new owners not only got it done by Monday but let me use a plug-in unit for the weekend. It was 96 degrees inside, so I was very grateful. The new owners treated me good, were very respectful and so were their employees. They have my trust in return.
