A huge thank you to your company. I highly recommend Jerry Kelly Heating and Air Conditioning to everyone;

It is the quality of your people and their work that makes the difference, and the reason I will refer friends to Jerry Kelly when an opportunity arises. Please convey my thanks to Jeff, David and Alex. Charlie Young

  • David We have been on Jerry Kelly's annual service plan for 10 years plus. During this time we purchased a furnace, AC and water heater. This past Saturday our furnace malfunctioned, one of the coldest mornings this winter. Matt from Jerry Kelly responded within 30 minutes of our call, quickly diagnosed the problem and had us back up and running within the hour. All at no charge as they stand by their products. Matt was courteous and very proficient. We recommend this company to all of our friends and neighbors.

  • Deb L. Last Saturday I had a new heater put in and had Joe K and John K install it. What a great experience we had with this two men. My heater was replaced and everything went smoothly. They cleaned up after themselves and worked non stop all day. Your technicians were such kind and such gentlemen that I enjoyed having them here. To say the least I had a great experience with your Jerry Kelly crew.

  • Ernie Just had the yearly service done for my air conditioning and as always it was done efficient, fast and professional. Graham explained everything in a friendly and understandable matter. Because of people like him I recommend Kelly to all my friends.

  • robert Allen B, Joe P and Dan S were involved in our purchase and install of our new furnace. They were all very polite and professional. They explained everything in great detail and made sure we were satisfied. We would recommend Jerry Kelly for all your heating and air conditioning needs
