  • Bankerbrad I've been a Silver Club member of Jerry kelly for a couple of years. I've been watching the letters you send out in the Winter about your HVAC specials to help keep your guys busy. My Furnace and A/C were 14 years old and I'm a couple of years from retirement. I decided to update my system to one more energy efficient with new equipment. When Shane came to service my units last month, he mentioned your current special price on new systems. We got to a fair price and on my next available day Dave and Tyler showed up at 8:00 a.m., took out my old system and installed the agreed upon system. They left at 5:30 on the same day. They were both professional, friendly and hard working. I would recommend these guys and, of course, Jerry Kelly for all of your HVAC needs.

  • Korey T Within minutes had my furnace working. Its nice to have someone that is knowledgeable and provides such great customer service. Business success is determined by the people who represent your company. JK he represents your company well Good Job Korey!

  • Gladys Graham did a great job. He wore his shoe covers. thanks!

  • Mike N. Graham arrived as scheduled and quickly went to work. He was very pleasant and professional during the visit offering his observations and answering my questions.

  • Warm and Comfortable Graham arrived on time and did a thorough fall checkup of our furnace, and even took the time to talk through the ticket with me. We appreciate the professional service.
