Ernie and his team had serviced our previous home for 20 years and then helped with a total rehabilitation of our next home, a 1925 Tudor. Hefferon worked with our unique project needs that blended both historic renovation and new construction to give us a state of the art, efficient, wonderful indoor climate. The team is smart, hardworking, and great partners across design, installation, and service.

Dealing with Hefferon was a real pleasure. From Ernie Hefferon to the office staff and the installers, everyone was unfailingly pleasant and answered every question I had.My first meeting with Ernie took a full hour+; he reviewed the existing conditions in my house and gave me different alternatives. The other company I contacted did a 10 minute look at my house and quickly came up with a quick and dirty proposal. Ernie's thoughtful approach gave me confidence that I would be getting quality work, tailored to my needs.My system was just installed, so I don't know how it will work. I do, however, have confidence that Hefferon will be there if I need them.

If you are looking for a reliable company with competent heating and plumbing technicians, look no further, Heffreon is your company. They provide the best service in the Danbury area, while their competitors don’t even bother to return your phone call. They are honest hardworking people who take pride in their work, which is lacking in our culture today. If I could give them a 10 star review, I would gladly do it. ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ ⭐️ ⭐️

We could not be happier with the service we received. The gentlemen who did our installation were friendly, helpful, and professional. We consulted with 3 other companies and none provided us with the innovative and cost-effective option Hefferon did and the results are exactly as promised. We highly recommend Hefferon.

I used Hefferon to install a new ducted and ductless heat pump systems throughout my house. The installation team was professional, friendly, cleanly, and happy to accommodate any requests and questions. I trusted their expertise throughout the whole process. I'd recommend Hefferon for any new system install.

I used Hefferon for the first time yesterday to diagnose my air conditioner problem. I was very pleased with their service. The technician was professional, polite, and I had confidence that he was being honest with me which, unfortunately, seems to be a problem these days with many less than trustworthy companies out there. I will also be using Hefferon to perform my natural gas furnace service this fall. The back office was also very professional and pleasant to deal with.

Friendly, polite, and professional! They got the job done efficiently and we are very happy with our new heating system. Thanks, Hefferon H&C!

Hefferon responded within hours to our emergency voice mail on Sunday. An appointment was scheduled for Tuesday. The technician arrived on time. After reviewing the particulars he determined the cause and repaired the system. Good to go within two hours. This was our first experience with Hefferon. They were highly recommended and we'll do the same!

Hefferon installed a new HVAC system in my house last year and they were great. Very polite and professional. We use them for our system maintenance and they are thorough and responsive to any problems or questions. Highly recommend!

update:we moved to a 1800s farmhouse house and called Andrew and Ernie to help update our HVAC. Our experience continued to be fantastic - thoughtful, kind, and patient - great to work with to understand our options, schedule the work, and feel safe while everything was installed during the initial months of COVID-19. Here we put in all new HVAC, moving from oil and natural gas and adding in central air. Now a few months in, and even with a super low oil price compare, we are saving around $200/month because we have a more efficient system that distributes the heat more effectively. This saving includes the cost of financing some of the equipment installation, but does not appropriately adjust for the value of keeping two young kids comfortable inside and sleeping through the night. 🙂 We continue to recommend and appreciate working with Hefferon Heating & Cooling!**********Any time people ask who installed our central A/C, we light up - Ernie and his team from Hefferon are skilled, thoughtful, friendly technicians who take the time to understand your home and artfully fit in the beast of a system into our home. We were treated with respect and were taught to understand our air conditioning - what the estimate entails, how the installation would go, what it's doing, how to operate and care for it. We never once thought we were just another job, and felt cared for, so that we feel confident about our investment. We have an old 1930's house with tiny closets - yet we barely lost space thanks to Andrew and the crew. I believe we gained comfort in our home, and feel like we can love it thanks to them! Make sure to call Ernie and his team!

We had the most amazing experience with Hefferon Heating & Cooling and would highly recommend to anyone who is installing AC or is looking for a service provider. From the initial consult, to the well-prepared site to the day of install, we were beyond impressed. They were neat and tidy and left the house clean like they were never here. The system is perfectly sized and kept my house comfortable all Summer. professional and communicative all the way through.

Ernie and his team delivered high quality service. I had them replace an old furnace in addition to adding a 3-ton AC unit to the home. They were on-time and did a terrific job.I had asked 3 HVAC guys to provide bids. Hefferon was not the least or most expensive but they were very thorough in the detail in their proposal and I was able to speak to Ernie, the owner, and felt confident in the high touch service they deliver. Give them 2 thumbs up.

Excellent experience with Hefferon. Like many others, my AC was badly effected by the most recent storm. It was a Sunday morning when it just stopped working. My friends had highly recommended Hefferon. Someone came later that morning to repair/assess the problem. I believe his name was Andrew, who was extremely efficient and professional. I needed a new motor blower which had to be ordered. The part came in a timely fashion and Mark came Friday afternoon. He too was very professional and informative of exactly what he was doing to repair the unit. All for a very fair price! They were very accommodating to my schedule, which conflicted with their normal business hours. I was very impressed with my overall experience with everyone at Hefferon. Needless to say, I too highly recommend this business for all your HVAC needs! Thank you!
