They showed up at 11 a.m. - two hours late (after the office lied about their arrival time). They were unprofessionally and sloppy dressed, stuck like cigarettes, and didn't introduce themselves. They just said, "Where's the furnace?" When I remarked they were late, they said they were at another house, contradicting the office admin report at 9:30 a.m. No Work Order. No IDs. No Identification on their truck. They didn't come in ready to work - no flashlight or tools. They opened my bedroom door (accidentally) when pushing the furnace room door aside. They complained that the unit to remove was "too big." Never worked in a mobile home(?). They walked out to their truck - and drove away after sitting in there for 50 minutes. They gave their boss some BS so they didn't have to do the job. When I called their office, I asked to speak to the receptionist's manager, who told me the BS story relayed by "my guys" and said, "This isn't going to go anywhere."

I'll say more about the quote that was given after the job is done by someone else. Let's just say he tried to take advantage of my need for heat.... and the guy that came out was from G and R Heating. Not who I thought I was calling.... there are too many other good companies to deal with this stuff. Find someone else. Update: another company did the job for less than half of what they quoted me!

I had not used Westenn before and wondered if any emergency service repair companies would be answering during the holidays. My call was promptly answered and a service person was on his way.

Last but not least, the pricing was fantastic and so fair especially because it was a holiday weekend!
