Hear From Our Past Customers!

  • Ed Greg B just did a service check of my A/ C, he did a great job. Explained everything even explained service agreement which I purchased. Keep up the fantastic service Ed

  • Lea Damrell Greg did an excellent job. He was very professional and knowledgeable about the service he provided. We will be requesting him in the future.

  • Sandy P. Dan S. came out one day, diagnosed the problem and gave me multiple solutions for correction. I ended up ordering 2 furnaces and an a/c unit. Dan gave me a great price and even re-did some duct work that was a pain in the neck. Derek, Nick R, Joe and Alex came out the very next day and installed all 3 units. They were polite, fast, knowledgeable, went over the units with me and cleaned up.

  • Megan Graham was quick and efficient at diagnosing the issue. Communicated my options perfectly and was very polite and informative. I would contact them again anytime for an issue I have.

  • Brian Graham was great. Got the issue diagnosed quickly and repaired in short order. The AC is back on. Will request Graham for future work.

  • R. Zaleuke Shane, the first person to respond to our A/C need was outstanding! He truly demonstrated the Jerry Kelly standard of excellent service, beyond what was expected. Chris and Taylor did the installation of our new Heat/A/C system. They were very professional, hard-working men. Excellent service by them as well.

  • Ken smith Graham was superb. Excellent service! Clearly articulated everything and was just all around professional! Highly recommend him anytime!

  • Dale & Melissa Our problem is that we had a old furnace and it was not keeping up with the St Louis heat. Jeff L and Tyler P came to the rescue and installed a new updated furnace and performed the needed service to keep it going. They were courteous, quick and professional and we appreciate them coming out on a Saturday morning as well.

  • Steve b My tech Korey was outstanding checking every detail of the the hvac system would highly recommend him to anyone needing repairs
