We recently had to replace our central Air Conditioning and received estimate from various HVAC specialists, including the one we currently have a service contract with. Shane, the sales constant, was by far the most professional, patient, kind, honest, and thorough person that I met with.

Christine K.

They were both very professional, informative and very neat and went out of their way to any other issues. I highly recommend them and hope their service lives up to the same.

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!

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.

Wayne S.

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+!

Jeffery B.

Everyone in the office I spoke with was so friendly and responsive. They called to notify me that the technician was running late, so I wasn’t sitting around waiting.
Our Technician, Giovanni, was excellent.

Ellen L.

Onofreo is an amazing company That is represented by excellent products and professional staff. When I first called them they were extremely responsive to my needs and took care of the initial concerns that I had with an old air conditioning system.

John S.

Excellent service and quick response. Also had what I thought was a leaking hot water heater but turned out something far less expensive. They responded back quickly and had everything finalized within 2 hours of my initial contact with their office

James V.

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!

Terri M.

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.

John 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.

The installation was installed neatly on the date scheduled and at a terrific price. We are completely happy with the professionally executed work.

Michael L.

I had Onofreo HCS install a new Hydro-air system last year to replace my 35 year old system that kept giving me trouble – Mark, his office staff, and his techs were prompt, professional, and clean. Mark showed up to do his estimate, I got the proposal signed, they pulled the permit, dropped off a check, and in three days I had a brand new system installed. I knew what was going on every step. The install looks great and they provided free cleaning and tune up service afterward. I have also referred my mom to them and she was thrilled with the service. I would highly recommend anyone who needs maintenance or a new system to Onofreo HCS.

Eric P.

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.

Bravo to Pat from Onofreo! He walked me through all the service needs for my hot water heater and heating ducts & vents. An overall fantastic experience and I will be calling Onofreo HCS for all future HVAC needs. Thank you 🙂

Carmen F.

Just amazing people even helped me with rebate paperwork from my electric company.Will use them again and so should everyone else.

Ralph S.

Amazing to experience an oil to gas conversion with Onofreo! Efficient, fast, and beautiful work!!

Melissa B.

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.

Theandra T.

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.

Onofreo Home Comfort Systems LLC installed a new ductless, mini-split air conditioning system in our home. Very completive pricing when compared with other area contractors.

Nick N.

In short, I could not be any more pleased and satisfied. You started the process with an excellent presentation, great salesmanship skills, and more than enough knowledge to allay any concerns I had. With your guidance, I believe we put together a system that will continue to meet my needs for years to come. I am particularly impressed with the Rudd heat pump water heater. But for your recommendation, I might have stuck with the standard 50 year old technology and heated water with gas or electric. Now that I have seen the heat pump water heater in action, going with the old technology would have been a big mistake. Thank you.

Scott O.

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.
