Then I called Paul's , their top notch technician came up with a completely novel solution. We had to order parts, yet he rushed them and kept in impeccable touch with me.

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.

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.
