Report
The recent heat wave left me with out functioning air conditioning. I e-mailed Leith at 9PM, asking for help. They called me 7:15 AM the following morning and had someone here by 7:45 AM. He quickly diagnosed multiple problems, pulled the spare parts from his van and had me back up and running by 9AM. Leith was VERY responsive and knowledgeable, with very fair pricing on their work.

Found this company last minute based on positive reviews. I am sure glad I did. I needed a full AC and Furnace replacement and they came out same day for estimate. They use quality equipment and the price was very reasonable based on other companies quotes. Two days later i had full install complete. They were very friendly and professional and I highly recommend their service.

I called, the lady on the other end of the line was exceptionally kind and professional. My family and I had just spent a very cold night without heat. I was ecstatic to receive a text within minutes of hanging up, that Robert the technician was in route and would be at my home with 6 minutes. Yes it's true, the tech arrived, assessed my furnace, and my family and I had heat shortly there after! Thank you for a well executed repair service!
