 Trustindex verifies that the original source of the review is Google. Called in morning and tech was available to come by same day. Was honest and up front about the issues with my unit, which ended up being a switch, instead of trying to push expensive repairs. Will definitely be using them again in the future. Thanks.

 Trustindex verifies that the original source of the review is Google. I can’t recommend him enough! He came out quickly, diagnosed the problem with my air conditioning, and had it fixed in no time. He was professional, honest, knowledgeable, and took the time to explain everything to me. His work was high quality, and he made sure everything was working perfectly before he left. After dealing with the stress of my AC going out, it was such a relief to find someone reliable who genuinely cares about their customers. If you’re looking for someone dependable, reasonably priced, and experienced, I highly recommend him. Thank you again for the excellent service!

 Trustindex verifies that the original source of the review is Google. I needed a capacitor at midnight and he picked up on the 3rd ring. Very cheap for late night after hours. Very reliable fella, when I got there he ran me through the process of repairing it myself on a AC unit he had. 5 stars great service.

I called after hours and they showed up promptly, figured out the issue quickly and fixed it within a matter of 2 hours. This included him taking a trip to Home Depot for parts. Honest and fair.
