"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."

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."

"Replaced water heater that had begun to flood the basement. Responded within a few hours and did a nice clean job. As they were immediately available, I didn't get other bids, but their price was in line with what I found online."
