Ductwork Design and Installation

Overly thankful for Ryan's amazing help! He was knowledgeable about my heat issues and was able to get everything back up and running! He turned a cold, terrible situation into a warm, lovely home!

Great Guys Nice work Thanks

Ryan is very knowledgeable, great at communicating, and does awesome work at a fair price!

Recently installed a natural gas furnace in the attic with Kevin and Ryan. They went above and beyond with helping me understand the process answered all my questions. I highly recommend and will definitely be using them in the future

I HIGHLY recommend A&G Heating and Cooling LLC for all your cooling and heating needs. Ryan is responsive, supportive, and truthful. We asked Ryan to install a wall unit on the first floor that is separate from the central air. We also needed to replace our central air system. Note, we did this while overseas and through facetime. Ryan did an excellent job and fit us in quickly. During the work, he discovered that the wiring in my home was not to code and called me immediately with a reasonable solution. I feel confident to have found our family HVAC contractor whose service is professional, high-level, and trustworthy. Call A&G Heating and Cooling NOW!

Hottest two days of the year - no A/C, and Ryan saved us! Great service and he was able to quickly isolate the problem. We’d definitely recommend and use them again.

Great service from Kevin and Ryan as always!

I highly recommend Ryan and Kevin! They just did a complete replacement my HVAC system. They quickly responded to my call to give me a quote and the job was complete 4 days later. They were knowledgeable, friendly and respectful of my home. Thank you AG for the impressive service and my peace of mind!

Ryan and his team are fantastic. They came highly recommended and I see why. Incredibly responsive, professional, timely, and educated me throughout. Couldn’t ask for better service.

Oct 30,2025. Thanks crew on your Attention to my gas heater, the new Valve worked out, heat is restored & Price was fair!

These guys are beyond professional and clean. So clean I almost forgot they even came. They showed up and went over everything with me from start to finish.. definitely recommend them to anyone! Btw they show up when they say they will!

Ryan and his crew installed a new AC system during the recent hot spell. They did a great job and were extremely professional and courteous. Very good to deal with and I would recommend using their services. We will be using AG Heating and Cooling for all our future HVAC service needs.

Great small company. The guys are super knowledgeable very friendly and honest came right out cleaned the boiler only did parts that were necessary even gave me a quote on a split unit support local.

A G Heating and Cooling replaced and installed an upgraded oil-fired hot water heater and an oil tank. The prices were fair. The crews were vey knowledgeable and showed up on time. Keving explained why he had chosen the burner and oil tank and their pluses versus other products. A job well done.

Ryan was very patient while I absorbed the reality that I needed to replace my furnace. I had three quotes and his was lowest plus his explanation of what he would do was the most thorough. The new hardware installation (pipes and boiler) was perfect, boiler room left cleaner than he found it, and just as expected, they were in and out in one day. This is an honest, thoughtful and professional technician.

We had an oil burner emergency just before the holidays on a weekend. Ryan returned our call immediately and arrived within the hour. He and his partner were very professional and diagnosed and explained our issues. They fixed our problems quickly, cleanly and thoroughly at a very reasonable and well explained price. Ryan, Thank you very much and have an excellent holiday.

Professional, prompt, and transparent. Highly recommend

Ryan and Kevin were so professional and efficient - was my 1st experience having them do work in my home . They did such a great job , left me feeling at ease , were so polite and clean ! Definitely a great team effort . Highly recommend !

I could not be more happy with the maintenance of the existing and the new installation of Mitsubishi AC split system units. I met Ryan and Kevin when they were working at my neighbor's house so I was able to witness firsthand their speed and efficiency and appreciate the craftsmanship of the end result. I invited Ryan to my house where he inspected the house layout and provided various installation options for the new system. A few days later I received an estimate which was presented with the full transparency of the equipment, labor and installation costs involved. In addition Ryan gave me an option to engage my own electrician and also recommended the local electrical company Mikkel Electric they usually subcontract with very reasonable quote that we ended up using. Come installation day, everything was completed in less than 7 hours despite some challenges reaching the house top floor. Even though the company does not have a ton of Google reviews yet I can confidently recommend it to anyone who is looking for reliable, dependable and reasonably priced local company in Bethel, CT and beyond. I am looking forward to work with Ryan and Kevin again should the need arises.

Ryan and his team is amazing. Service is always quick and top-notch. You’ll get a good understanding of what issues you have and how it got fixed. Very quick to respond as well! Highly recommend his services.
