Report
I was told that the first service was no charge and then I could sign a service contract after that. Someone would call me and set up appt for the service call. Well it's been over a year and no call, so I called them and she said they don't do a yearly service for no charge and only do service with a contract! I think they need to get their act together! Do not use these people if you expect service on your ac. I will not call on them again. BTW I paid over 4500.00 for a new central air system that they installed.

Air conditioner went out last night and I put a request for service on their website. I heard something by 6:20 a.m. the next day via email. Tech was scheduled to be here by 8:30 a.m. Tech arrived at 8:10 a.m. and my air was going by 9 a.m. Tech was very knowledgeable. A+++
