"I'd become increasingly concerned about the company I was using for my AC and heating needs. When I knew we needed a lot of work doing, I decided to search for a new company that I could trust. We needed to get 4 new AC units installed. They were 17 years old and leaking, so we took the plunge and decided to replace them. I had a lot of questions around the systems in my house and what to install. During my phone conversations Donny was extremely helpful and patient. He answered all my questions and I believe that he gave me honest suggestions on the best solutions for my home and living situation. I found him to be honest, trustworthy and very knowledgeable. The install went smoothly, one of the units was tucked away in a tight closet in my daughters room, and they dealt with that easily. They installed 4 new controllers. They were tidy, and worked long hours to get the job done. In addition they spent time explaining the new systems to us and answering questions of ours that arose. We are really pleased with the new systems and controllers, we have peace of mind that we've installed good, reliable systems, and that we have a great company looking after our AC and heating needs. I also hired them to do annual service visits for our heating and AC. So far they have performed the winter maintenance visit, and identified a couple of things that needed addressing to prevent possible problems this winter. What they recommended made sense to us, and we thought they were valid and worthwhile repairs. As we trust this company, we decided to go ahead and get the work done. Chris D came to do the repair job. He was very friendly, helpful, hard working, and did a great job. He also took time to make sure we knew what was going on. I'm hugely relieved that I found this company. It's increasingly rare to find companies to help out in the home who are good at what they do, honest and trustworthy. I highly recommend them. BTW I'm also impressed with their office support staff. They are super friendly and helpful, calling back when they say they will. Booking appointments is super easy with this company."

"If I had to describe ProTech Heating & Air Conditioning in a few words they would be: Professional, Punctual, Quality Service, Responsiveness and High Vale. Ricardo was prompt, professional, knowledgeable and hard working. He repaired my A/C system at a reasonable price and communicating was an absolute pleasure! I highly recommend ProTech Heating & Air Conditioning."

"Great company! They've been super responsive when we've had questions or concerns, and deliveries are frequent enough that we never have to worry about running out of heating oil."

"Prompt, efficient service --- Technically knows gas furnace products --- More importantly knows the economics of keeping up with repairs on a 30 year old unit vs going with a new unit --- Not a sales pitch -- just facts ---- Went new and the cost including nicely done installing was much lower than I originally thought it would be . Review by Clark D. in Madison CT"

"Came to the house ON TIME, very professional, provided exact service as hired. Recommended logical follow up service and emailed with updates. After hiring terrible contractors that never called back or never showed up for scheduled work, this was a pleasant experience. Thanks HARP!"
