Had to change the zoning board, wiring to HVAC and thermostats on an 30 year old system . Responsive, on time arrival, fair pricing – true professionals. Was absolute pleasure to see how their engineer arrived on time, communicated everything he has done, and the work performed. Will definitely contact them again for anything HVAC related.

We just had a ductless split unit system installed in 4 rooms of our house. The people at Onofreo are amazing to work with, from the owner Mark, to the office staff to the guys coming out and doing the work. The install happened much quicker than I anticipated and they were SO clean, I would have never known they were in my house cutting into walls, etc. The system itself is awesome – very quiet and cools down the house super quick. When Tom came for the consult, he told me I’d never want to leave the house again and he was right. Best thing we ever did! Thank you Onofreo!

The install was well planned and started on scheduled date. It required multiple condensers and 4 wall mounted units. The team was friendly, professional and worked non-stop through two very hot days directly in the sun. The install finished ahead of schedule. Cabling is very neat. Team cleaned up when finished. So, start to finish just as promised. The Mitsubishi units work very well and are extremely quiet. An overall A+!

This company was an absolute joy to deal with helping me switch from oil to gas and taking care of every step of the process, from sales to installation to dealing with gas company. Kelly is a gem. Can not recommend enough!

Anthony, Mark, and Kelly have helped install, fix and maintain our furnace and AC units for many years now — they are the best, and yes, we have tried the rest. But we will always call Onofreo from now on. Excellent work, done fast and reasonable rates — great people too.

Anthony called prior to the visit. Arrived on time & found a capacitor was bad on our compressor. He went on to check the entire system to make sure it was running right, without me having to ask. Very friendly & explained everything he was doing. Kelly was also very pleasant to deal with on the phone.

Onofreo has proven themselves yet again to be the best in the business. My wife and I went to them a second time, this time to replace our Central AC unit. First of all, they came right out to inspect, then they gave us a price that was much lower than I had expected. The install happened very quickly and everything is perfect. Mark and his team are absolutely wonderful and I can’t recommend them highly enough. Truly a first class company all around. If you need work done, this is where you should start. Thank you for another great experience!

Joe B.

I had an issue with hot water system. They were very fast to send someone out on the same day to diagnose the problem and quickly got in parts the next day to complete the job. Kept me closely updated on when a repair person would come to my place. Very happy I can shower again with hot water!

Monkol L.

Mark and his team are the best. They are honest, transparent, hard working, professional and punctual. They answer all of your questions, even the dumb ones, and I had plenty of those. They removed my antique furnace and installed a complete heating system in 2 days as promised as well as a hot water heater on an emergency basis. They also wear masks. Call them. You won’t be disappointed.

Elaine M.

The technician was very polite. He assessed the situation quickly but thoroughly and provided a honest diagnoses. He told me exactly what was wrong and needed to be done and he performed the job well because everything is working perfectly. I will call them for my future needs and recommend them if you do not have a HVAC provider.
