"I have been using Mike as my Heating and A/C guy for 17 years and he is awesome! He is very personable, professional, knowledgable, and reasonably proced. He has never tried to sell me anything I don't need (like some others I dealt with). I have also used him for emergencies (water heater) and he has been there when I needed him."

"I didn't give them a quality grade yet because they haven't done anything other than inspections, but so far I'm very pleased. Most importantly, I've been impressed with their honesty. They've had two opportunities to tell me equipment was broken or needed replacement or service, and I wouldn't have known otherwise, and yet both times they've been honest and upfront, telling me no service was needed. From what I've experienced and heard, this is a rare quality in an HVAC company and I'm glad I've chosen to work with them."

"I would recommend this business to anyone that needs HVAC service. The experience and service provided by Roy Rogers was great. The technician arrived on time. He was both thorough and informative during and after the service. I didn’t feel pressured to make any purchases. He simply presented the facts/solutions to allow me to make an informed decision."

"The service and everything was fine. We had just some issues that was out of their control. We had to put in a few different water heaters and then they had to removed the few different water heaters before we had to upgrade so the price was a little bit higher than we wanted but it was kind of out of everyone's control at that point. The guys were really nice. They made a lot of trips to the house. One thing that I would say is that they leave just a little bit of a mess that they didn't clean up in the laundry area. I think it was a pretty good experience."
