This is my second time using Hefferon Heating & Cooling. Ernie and his crew have always come through me. Showing up on time, clean and neat and ready to work. Everyone was dresses in proper PPE for Covid 19. All work spaces were left clean and neat at the end of the day. Pricing was very competitive both times I have used Hefferon. I also use Hefferon for all the cleaning and maintenance every year because I can trust them. I will use them again anytime I need heating and cooling done. Well run... company!read more

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!read more

Wow - first-class, top-notch expert service at a fair price! That is hard to find these days! Like many others who had their A/C knocked out after the tropical storm the waiting time was days to get someone to my house. Hefferon went above and beyond to slot me into their schedule for the next day and Andrew even showed up a few minutes and made quick work diagnosing the issue. He knew exactly what he was doing, he had everything he needed on the truck, and in a few hours we were back in... business.I really appreciate their customer orientation, knowledge, training and experience as well as their fair price. They have me as a customer for life!read more

The Hefferon team were incredible! I had a central A/C system that looked hopeless, I had gotten quotes that were sky-high, then Hefferon came, diagnosed the problem, and gave me a choice of replace or repair; we repaired and I could not be happier. Everyone else wanted to replace the system, I'm so glad I went with Hefferon -- they repaired for a fraction of the price and A/C is working wonderfully.

Very impressed with the tech and services performed. He arrived early and immediately began a discussion about our system. Found a minor problem, they had a replacement part and was done.Provide a heads up on the age of the system and if a problem should arise to call the office

Hefferon is a life saver! They are one of the easiest companies to work with! My husband and I just purchased our first home in January and when we had it inspected we were told my the inspector that since it was winter we weren't able to have the central air tested. With everything else checking out ok we assumed that the central air would be good as well. We were unfortunately wrong! We found out on a Saturday that it was broken called one other company out they diagnosed it as being look on... freon. They filled it left and it still wasn't working so we decided to try other companies. Hefferon was one of the ones that we called. They were nice from the very start! Andrew S came out on a Friday cleaned the machine and told us that it looked like it hadn't been maintained in a while he thought that the machine being dirty might be the issue, so he cleaned it and left. The AC worked all day Friday into Saturday then stopped working again. I called them Saturday afternoon the on call tech called me back within 10 minutes of when I left the message. He stated that he would contact Andrew and the owner and let them know. Monday morning I got a call from the office and they stated that Andrew would be out that day. Sure enough he was here! He looked at the unit outside and told us that there were several parts that needed to be replaced and told us a cost. He also told us the cost of replacing the whole unit. He didn't pressure us at all either way and told us that it was up to us and what we were comfortable with. He left my husband and I to talk while he went and looked at the unit downstairs. We decided it would be a better idea in the long run to replace the whole system. He got us the quote right away within 24 hours and was able to schedule us within a week! He came today to replace the unit and he was so professional and polite. I cant thank him enough! He was amazing and we will forever use Hefferon!read more

Ernie and his team are very professional and it shows in the work they did for me. I'm very happy with the Trane heat pump that they installed. They installed the outdoor unit, ran new duct work in the attic of my raised ranch, and also subcontracted the electrical work to be done the right way. The ductwork is immensely tidy and the attic is still very usable for storage. They even relocated the ductless mini split system that I had in the living down to the lower level for free. I'm very... happy that I don't have to use baseboard heating anymore. The central air conditioning and heating is the only way to go and it's definitely worth the price. The Hefferon team will treat you right. Thanks.read more

Hefferon is the BEST at what they do. I have needed them three times, and every time they are always polite and reliable. They are willing to explain what they are doing, and to repeat it patiently to me when I ask them to, for whatever reason.This last time they came I needed a new unit on my roof. I got a reasonable quote from them. They arrived on the date set , and at the agreed upon time. I was thrilled with their work and with the fact that they finished the same afternoon. It was really... hot up there and they never complained!read more

Ernie was nice to work with and he helped me find just the right product in my price range. He was able to provide lots of options with quotes. Glen and Evan did the install and both men were very professional, courteous and safe under the current COVID conditions. They did a great job ~ I barely knew they were there as I worked from home! Thank you again! Jen Ucci

Extremely satisfied with the entire Hefferon team. First year in my home I had placed a service call for basic maintenance in June 2019. A service tech named Andrew came out and was extremely knowledgeable and professional. March 2020 I was having more serious issues with my old unit and placed a service call at 9:00AM on a Friday. Christina had Andrew out to my home less than an hour later. After the diagnostic began there was a need to allow the compressor to cool down on the heat pump.... Rather than come back another day, Andrew left to another job and returned a few hours later to finish the diagnostic. We decided that with the age of the unit, replacement was the best option. A day later Andrew emailed me with numerous options, detailed pricing and clearly and concisely answered any questions or concerns I had. After the proposal was signed they scheduled the install soon thereafter. The install was as smooth as could be. Andrew arrived on time, explained how the job would be completed and was sure to wear shoe coverings when entering my home so that no dirt would be tracked in. They worked throughout the day and I barely knew they were even there. After install Andrew went over every aspect of the newly installed air handler, heat pump and thermostat and again answered any and all questions I had. I look forward to doing business with Hefferon in the future and highly recommend them for any and all of your HVAC needs.read more

My neighbor had an entire new heating unit installed by Hefferon and was extremely satisfied. Recently, when maintenance needed to be done on my heat/AC, system, I called Hefferon. It was an excellent experience from the initial phone call to finish. James was polite, professional and extremely well versed and knowledgeable He explained everything as he went along. I will be using Hefferon for my A/C/Heating needs going forward.

Last week we had an emergency heating situation, which was remedied by the skillful tech team of Mark and James of Hefferon Heating & Cooling. We found the company on a HVAC google search.The office manager, Christina, took our call and sent the techs to our home ASAP. We were impressed by the quick response to our request; by the pleasant and courteous demeanor exhibited by Mark and James; and by the high level of professionalism demonstrated and overall excellent service provided during... their time in our home. As a result of our highly satisfied experience, we signed up for the air conditioning service contract.Hal Dalcher and Debbie Smithread more

Hefferon replaced my 12 year old hot water tank this month. A convenient appointment was made and two technicians came on time with everything that was needed. As usual they were careful to cover the floors and clean up. Everything is working very well and what ever questions I had were answered. Hefferon normally services my heating and cooling systems and keep things operating well.

Was looking for a company to come look at our furnace after we bought our condo. Reached out to a few other places multiple times and got no response so after reading some reviews we decided to go with Hefferon. Called them up and scheduled an appointment quick and easy, the service men (Mark and James) showed up on time and were very friendly and helpful. They took the time to look over my furnace and explain what was going on and the different options we could take going forward. Even signed... up for a service plan so we are now a priority customer. Definitly glad we called these guys and will be sticking with them. Thanks!read more

Hefferon HC replaced our boiler this month and did a great job. They were knowledgeable, skillful, and delivered their service exactly as promised. Installation took one day and we hardly knew they were there. The owner, Ernie, visited before during and after, making sure we were satisfied. His company delivered quality service at a great price! We are very happy with their service.

I was having an issue with the air handler to my heat pump leaking hot air into the closet where it located. I wanted a consultation on how to correct this and heat and balance my system better. Mark came out and found several issues that he easily fixed explaining everything to me. I am thrilled with how he handled the problem. He is now my new guy and Hefferon my new HVAC company.

Called Hefferon to get a "second opinion" on a furnace service repair recommended during a routine inspection by one of the other heating and cooling firms servicing Danbury, CT. Boy was I glad I made the call! The part did not need to be replaced and I saved over $300.00. Who you choose to work with matters, and I feel I can trust Hefferon to provide professional and honest service.

  • Doing business with Ernie Hefferon has by far been the best repair experience I’ve had during 22 years of owning this house. First off, I was to deal with personable Ernie himself, not with some sales rep whose commission would be built into the price. The replacement of two compressors and air handlers was accomplished in two days by polite, competent, and well-spoken technicians who didn’t seem to mind a question or two from me along the way. Don’t even bother to get alternative quotes; you won’t do any better.

  • BEYOND EXCELLENT!!! We have a 300 year old home which 3 Companies stated they were not able to install an AC System because of the limited head/attic room. Not only did Hefferon's staff find a way to install our AC System in VERY CREATIVE and excellent ways-they were 2/3rds the price of the only other Company that said they could install a System. Hefferon's very astute team of installers were so respectful of our home-always wearing booties upon entering, always very respectful of informing me of all they were doing. True gentlemen, very knowledgeable and informative of our Trane System which not only is our AC unit but is also a supplemental heating unit for days that are above 0% and freezing. BEST experience of our renovations/upgrades and this past winter was so enjoyable as our guests were able to control their own zones, and our home stayed a perfect temperature even on the coldest days without overheating as with our traditional oil heat. In addition, we chose the HEPA filter because of my husband’s allergies (thanks to their different options of systems to install). Today they came to do our bi-annual cleaning of filters and the same courtesy was shown. The system is running PERFECTLY!!!! Thanks to all of you at Hefferon for all you did on many levels of our home and on many levels of professionalism!!! Forever grateful!!

  • Great service! We had new heater and a/c units installed and Ernie and his team were terrific. They even offered to help with a problem we were having with poor air flow to certain rooms in our house due to improper ducting done by the original installer. Pricing was very competitive and they assisted us in getting rebates from the manufacturer and also our energy provider.

  • Hefferon Heating and Cooling installed our furnace and air conditioning a few years back. Recently, they put in a mini split heat pump in the room above our garage. The owner Ernie was very friendly and professional. He came out to look at the job and answered all of my questions. A few weeks later they installed the unit. Before they left, they made sure I knew how to work the unit worked and showed me how to maintain it. I would highly recommend Hefferon Heating and Cooling to anyone looking for great prices and quality work!

  • After having several quotes from companies who had questionable reviews I found Ernie at Hefferon. He came and we discussed the alternatives, several times until we were both comfortable with the choice I made. on the agreed date the equipment and crew showed up at the same time. They worked extra hours to get my old heat pump removed and replaced with the new Trane system in two days. Afterwards Andrew and Mat walked me through everything they had done and gave me instructions on how to operate the system. The work is neat and they cleaned up as though they were never there. I am very happy with HEFFERON so far and have no problem recommending them to anyone interested.

  • 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!

  • After getting the "bums rush" from my previous HVAC service company, I called a friend who recommended Hefferon, and so I gave them a ring. Surprisingly, the woman who answered the phone said, "I can have a tech there in an hour." Andrew & Max were on time, and diagnosed the problem; my central A/C was dead. They wrote the report, called their boss and said, “we’ll try to get a new unit in this week." Well, to my surprise, Ernie (the boss) moved some things around, and the techs, Andrew, Max, and Vaughn were here 2 days later doing the job, and they did it well. Courteous, efficient, "stand up" guys; you can't ask for better than that. Ernie: thanks for making the time to install the new unit; Andrew, Max, Vaughn: thank you for a job "well done." This is not false praise; these guys are good!
