"Outstanding company! The owners are mechanical engineers and were able to figure out why a unit previously installed by another contractor caused mold in my ductwork. They completed a Manual J calculation report that indicated the unit was too large, and they replaced the unit. Previously, this contractor identified that the static pressure on both of my HVAC units was too high and appropriate adjustments were made. All employees are professional, knowledgeable, friendly, responsive and extremely helpful. Hands down, this is the best HVAC contractor I have ever worked with."

"I had a great experience with Kelly's A/C. They installed blown-in insulation in my home, and the difference was noticeable right away—my house feels more comfortable, and I’m already seeing an improvement in energy efficiency. The team was professional, on time, and kept everything clean throughout the process. They took the time to explain the work and answer all my questions. I would definitely recommend them to anyone needing insulation or HVAC services!"

"I found New Gen Plumbing on Angi and selected them due their high rating. Well the rating was well deserved. They contacted me the same day and scheduled a FREE consultation. I was scared they were going to tell me I needed a new wyd heater but they didn’t. Thank goodness! I have a tankless water heater they simply needed to be descaled. Sixto did a great job and I’m back in business with a plan to keep using them going forward. Sixto even gave me some pointers on my water filtration system the day would help the overall performance and efficiency of my water heater. Much appreciated. I highly recommend!!!"

"John Moore sent a gentleman out initially to assess the problem, he happened to be a Supervisor. He was extremely professional and very complete in his assessment of the problem. He recommended that we replace our unit due to its age and condition. Then he worked with us to get the best unit for our house and worked with us on the financing options. Tom Lee was the initial person to come to our house and once we had decided on our plan of action Tom went above and beyond to ensure that we had the best possible system for our house. Excellent customer service skills and a very nice man. We got lucky !!!!! The installation crew was even better. They were very professional, courteous, and precise in what they were doing. It took some time to complete the job, but not because of the crew; it was due to the fact that they went the extra mile to make sure that the install was done correctly and they had to correct some mistakes that a previous installer made (not John Moore staff). My wife and I would highly recommend any and all John Moore services for your home needs. We have used their Plumbing, Electrical and now their A/C service teams and they are all top-notch. Excellent company and we would HIGHLY recommend them to anyone."
