What Our Customers Say
“Another company quoted $10,000 to replace our furnace. Paul came by that afternoon, found debris causing the motor to seize, removed it, and our heat turned on. He only charged us $99. Friendly, honest, and very knowledgeable.”
— Hannah B. · Yelp
“Paul is simply the best to work with! He's now done mini-splits, water heater, and our annual furnace cleanout for multiple years. Incredibly responsive, very fair pricing, and gets work done quickly and efficiently.”
— Matthew S. · Google
“Excellent service. Everything was explained up front, very polite & professional. The technician did very thorough work — I was impressed with how thoroughly he took care of our burner. Glad we found a local company to service our HVAC.”
— Nancy B. · Facebook
“I've used him twice and both times he showed up within an hour of calling. We didn't have heat and he got it up and working in under an hour! So thankful he was able to get it done right away since the next few days were very cold.”
— Ali C. · Google
“I was told by three other companies that my 20+ year old AC unit needed to be replaced. Paul came out the next day, found that a few parts needed replacing, turned on the unit and it has been working ever since. I will never go to another company.”
— Carol S. · Facebook
“Our AC stopped working and Paul responded immediately. He was thorough, detailed, and professional. As first-time homeowners, he was very patient in teaching us how to take care of our HVAC. His prices are very reasonable.”
— Amelia Z. · Yelp
