We recently moved into a new (to us) home. I discovered the garage only had one outlet (other than for garage door openers). Called Jerry Kelly to get an estimate on installing several more as well as a motion activated light switch for the garage. Jake came out and provided a clear plan and reasonable estimate. He then returned to do the work he had provided an estimate for. Although the day was very warm, he spent a lot of time in the garage attic running wire. He set four additional outlets, including and GFCI outlet. In addition, he installed the motion activated switch, and programmed it. Once the project was complete, Jake explained his work in detail. All in all, Jake spent a little more than five hours on the project and we are very happy with the result.

Alex, of Jerry Kelly, came to do an annual furnace maintenance and cleanup for a 15-year old system. He was great! He made sure everything was working as expected, cleaned up the compressor, and installed new insulation for the compressor line. Alex was professional, courteous, and friendly during the work. He explained everything he found and answered our questions thoroughly. We definitely plan to keep using Jerry Kelley Heating and Air Conditioning after our wonderful experience with Alex.

Will B. from Jerry Kelly Heating and Air Conditioning did an amazing job with my AC tune-up! He was clean, considerate, and knowledgeable. He explained everything clearly and patiently, answering all my questions. No pressure tactics - just honest advice. In the course of our conversation he gave me a few tips for better efficiency with my system. I signed up for their Purple Perks Club, which I think will save me money and give me great peace of mind. Will B restored my confidence in HVAC service people. I Highly recommend Will B. and Jerry Kelly!

Noah Crews was professional, clear, and friendly. He arrived on time, explained everything, and showed respect for our home and dog. He even covered his shoes with protective booties—an unexpected but thoughtful gesture. Throughout the visit, he stayed in touch and checked in as needed. When he left, he cleaned up after himself and left the place tidy.Noah’s practical, caring approach made everything easy. I highly recommend him!

I had Jerry Kelly out for a maintenance check. Will B. was friendly, knowledgeable, and pointed out the issues he saw with my old AC unit. He let me know my options and pricing, and I have asked for a follow up. Great customer service!
