This was my first time using United Mechanical, Inc. and I am so glad I did. I called and they were very nice on the phone and sent someone out the next morning to check on my HVAC unit. We decided to install a new unit. The servicemen were polite and courteous. They answered all my questions and even cleaned up after their job was complete. I would highly recommend them because you can believe what they say. They even checked on a couple of things that were not related to the HVAC installation and were very helpful.
