Gill was amazing and very easy to work with, called him at 8:30 with an ac problem he came out the same day by noon it was fixed. He fixes it for a very reasonable price. Now it works great I would highly recommend him.

On 8/25/2023 Gary had this to say:
Had them check out my A/C today. got there pretty much right after I called them. Very professional and thorough. I am retired now, but worked construction all my life, and have worked many of the trades. They were great, and most of all... very reasonable, very honest people which goes a long way these days. I would not hesitate to use them again, and I am sure somewhere down the line, I will call them again.. Thanks Gill Testimonial written by Gary on this site.
