We had a great experience with the installation of mini splits. We had five installed and the crew was professional , friendly, and the workmanship was top notch. I definitely recommend them.

Ernie Hefferon and his staff did a large furnace replacement job for us. We couldn't be happier with the way the staff worked and how they interacted with us. The office staff and work crew took whatever time we needed to explain the processes. We put the job in their knowledgeable hands and they passed with flying colors!Thank you Ernie, staff and crew. We will highly recommend you to anyone in need of a great HVAC company.

I contracted Hefferon Heating and Cooling in Danbury CT to install a full HVAC system with heat pump several months ago. They worked with me on scheduling the install (which had to be postponed several times on my end) . Once the schedule worked out the technicians showed up on time and did an absolutely amazing job installing the system. They kept everything exceptionally clean from day to day and, set the system up in a very neat and organized manner leaving me lots of storage space in the attic despite all the duct work. The lead tech (Lee) did a great job of explaining every step. After the install Christina (the office manager) took care of all the rebate paperwork. All in all I am very happy with the results.

Hefferon has been our go-to for heat and AC service on our house for more than 20 years. They recently replaced our 24 year old oil furnace. They had the best price and were fast, professional and clean. Highly recommended!

Ernie and his crew were outstanding throughout the entire process. I highly recommend them for all your HVAC needs. Andrew is a total professional and very knowledgeable. He stepped us thru the entire process. The crew who did our installation was very respectful and took pride in their work. I’m glad to have them around. An absolute pleasure.

The technicians were on time, professional, and knowledgeable. They kept me informed as the installation progressed. They were very helpful with the installation of my Internet thermostat. Ernie kept his word with regard to the installation date and stopped by each day to check on the progress of the installation and workmanship. I would recommend Hefferon to anyone looking for a new HVAC system.

Heffron Heating and Cooling is the most professional and reliable HVAC company in the Danbury area, likely the entire State. In dealings with Heffron, you know you’re getting honest answers/advice so there’s no need to worry about being taken advantage of in a situation you have limited knowledge. They also provide fair pricing, you usually know the cost before the service begins. I wouldn’t consider any other company for my Heating and AC needs. Thank you Heffrons!

Hefferon and their staff are top notch! Andrew is a skilled professional along with being very kind, he's just amazing. He took the time to explain and show me what the problem was and how he was going to fix it. Which he and Freddie did in a timely manner. Highly recommend Hefferon!!

I was not a regular client and they still came out incredibly fast, other places make you wait a day or two. Andrew was super friendly and informative. I was so happy with my experience I’ll be signing up for regular service.

Hefferon to the rescue! We’re not customer but they just gained us and don’t know it yet for their service plan next year.Our AC suddenly stopped working, of course right before the hottest week of the year to-date. Our service providers didn’t have availability until Monday and with three large dogs panting, we couldn’t wait.I called multiple Danbury HVAC companies yesterday and Evan from Heffron was the only one to call me back. He mentioned he could be there tomorrow morning (today!), and he sure was.He was very efficient and friendly! Top notch service and my dogs are I are forever grateful.Thank you, Evan!

If I could give them a 6 I would. First: the office staff is pleasant both Dina and Christina are very professional. Second: the price and the quality of products are great. Third: The workers are thorough, respect your home and are very helpful. Ernie the owner aims to please. We needed a big job done from ductwork to heat pump and air handler We met with other companies prior and no one could give us this type of quality within our budget We are beyond happy. It’s nice to work with people that still take pride in what they do.

Hefferon is always so helpful and works quickly to get to your home when you need them. The techs are always so kind and helpful. Hefferon installed a new system for us a few years ago and they are the only ones we will call for service.

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.

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!

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!
