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.

On May 1, 2023, Jason and his assistant arrived promptly, as promised at 8:30 am. It didn’t take me long to realize Jason was what I consider a dying breed. At he end of each day during this 4-day project, he left my basement neat and clean with the materials and his tools secured for the next day’s work. Maybe it’s just me, but I haven’t come across a whole lot of people in the building trades in recent years who are as skilled, knowledgeable, and meticulous as Jason. It was quite evident that he takes pride in making certain every detail of his work is done as a professional. In addition to his skills, he is very personable, taking the time to explain different solutions to the inevitable problems that arise in removing an entire heating, cooling, and hot water system and replacing it with the newest technology. After all the “heavy work” was completed, Jason took the time to explain the interactions between the furnace and the heat pump so that I understood what to expect and how the units would perform. And finally, he walked me through every step of programming the Bryant Connex thermostat. Again, a knowledgeable professional.

The final leg of what I consider a perfect trifecta, is Shana. She kept me informed about my project, but what really impressed me was her lightening fast return on the half-completed rebate applications I gave Jason at about 3:00 pm on the last work day at my house. Via email, Shana returned the application “neat and complete” at about 10:30 am the following morning. I can’t tell you the number of times I have had to follow-up and prod staff to get a return on something I asked for. Anyone who speeds up a process leading to a sizable rebate for me is super. Kudos to Shana!

Andrew, thank you again and please pass my comment to the “powers that be” in the company.

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.

March 1, 2020 – We put in a last-minute plea for help after our heat decided to stop working today, on a Sunday of all days. Kelly helped organize it and was very efficient. Anthony arrived so fast and was very thorough, informative, and professional. He gave us a ton of good suggestions and even helped us figure out how to use our home’s humidifier system that we had never touched. Now we have heat again, and we might not get zapped by static electricity so much as a bonus. Thank you for the fantastic service!!

Chris Palmieri

January 21, 2020 – We called them when our heat stopped working. They came out quickly and were able to get us up and running again.
The technician was very knowledgeable and friendly. Will definitely use again!

Lance Lombardo

January 9, 2020 – Awesome service and not heavy on the bank book. Total professionals. Came out pretty quick in a time of dire need. Anthony addressed the problem pretty quick and had our furnace fixed in a short time.

Pellegrino Pro Motions

October 30, 2019 – Onofreo just installed our new central air and air handler unit. They did a great job, were professional, prompt, and worked with us on price. Thank you so much!

Patty G.

Want to give a big shout out and thank you to Onofreo Home Comfort Systems of Milford, CT!! They just installed a new A/C and gas furnace in my home. From Kelly in the office who coordinated and managed the installation, to Tom who first provided me with the proposal for the job, and finally to Bill, Chris, and Ben who completed the installation in just one day, everyone was very professional and accommodating, and took every safety precaution necessary for the time we are living in. Any question or concern I had prior to or during installation was quickly resolved without hesitation. I highly recommend this company for your heating and air conditioning needs.

Chad P.

Exceptional and friendly service from the first message through the appointment. My ancient oil burner started running rough after a fill-up so made an appointment to have it tuned up. Two nights before the scheduled appointment the system stopped working completely and they were able to move up the appointment and get us back up and running the next day. Highly recommend!

Cindy M.

Could not have done better. They delivered 100% of what was promised. Excellent service. Kelly is wonderful. You cannot go wrong with these folks.

Joe B.

Our furnace died over the weekend, Onofreo came out and tried to fix it, it was 30 years old and needed to be replaced. They came out the very next day and replaced the whole system. They were amazing, very nice and professional, the price was much better than I expected, and everything is working great now. The installers took the time to clean up so well it looked like they were never even there. I would highly recommend Onofreo and I will be calling them again next time I need work done, no need to look elsewhere!

Toshi S.

Our A/C did not start, and based on the Yelp reviews, I called the Onofreo Comfort System. All the transactions were done through the Yelp’s messenger system. (My choice) Fast and thorough communications, always updating the status of an appointment. Mark, the owner, came to assess the problem. Turned out the mice chewed the wires in the outdoor unit. He told me that the capacitor was still good, no need to get replaced. Very honest and trustworthy. He gave me the accurate estimate, and fixed the problem in less than 30 minutes. I highly recommend the Onofreo HCS. In fact, I am going to ask them to service the A/C from now on, and also our oil furnace.

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!

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

Scott O.

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.

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.

John T.

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.

Theandra T.

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.

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.

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.

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.

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.

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.

P K

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

Melissa B.

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.

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.

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!

Heather D.

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.

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.

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.
