We recently had Shelton Commercial Refrigeration Repair come out and install a new American Standard heat pump system in our house. Their work was very professional and the installers were great - informative and knowledgeable. We are very impressed with the company and will be recommending them to all of our friends. Thank you for a job well done!

I have used 911 Heating and Cooling three times. Aside from everything else, they gave me the impression they really cared about my house. And they were extremely neat and careful.

We called Semper Fi out to diagnose an issue we have with poor heating into a bedroom in our home. The tech showed up on time. He was professional, and asked me questions regarding my problem with our heating. He went up into the attic to inspect the heating unit and ducting. He told what the bedroom in question is the furthest away from the furnace so the duct work has to travel the furthest to reach the vent. He gave me some options to make the system work better and was honest that we may still not see much improvement. So at least we know we the room is colder than the rest of the house. I have Semper Fi perform the annual inspection and maintenance on my heat pumps. It’s always straightforward. If something is needed the tech explains why. In addition Semper Fi is a veteran owned company and the provide a 10% discount for veterans. I highly recommend and endorse Semper Fi Heating and Cooling.
