My old ('94) clunker of a unit was having issues heating in mid winter. I called it in and the tech (Vince) came out the next day. He didn't have the part on the truck but was able to hunt one down locally and came back out the same day to install. He was very ethical and didn't try to talk me into a new unit. Couldn't ask for anything more. I'm a Realtor so I've used lots of contractors over the years. They did a good job for me so I would definitely recommend.
