Reliable Repairs

Appointment confirmation was very appreciated.

Furance stopped working, I called AG. The team showed up same day and got the heat back on quickly. Good call if your furance or AC needs a tune up.

They came right away and were able to help when we were in a pinch

AG Heating & Cooling LLC did a fantastic job servicing my system. Replaced old parts, cleaned, and system checked the performance. Ryan is very thorough and explained components during the process. The techs left the site clean and efficiently performed the maintenance work timely. I highly recommend their service!

Estoy muy contenta con los servicios de esta compania, e tenido muchos problemas con mi calefaccion y realmente Ryan fue la única persona que resolvio el problema. Ryan y su equipo llegaron se tomaron su tiempo y una vez terminado su Trabajo me explico paso por paso q habian echo. Muy feliz con la amabilidad, y su Trabajo!!!! Muy recomendados!!!

I’ll never forget trying to fix my furnace, again, for over two hours in the cold basement. It seemed I couldn’t bleed the line enough. It was so late at night and my fingers had turned purple. I had to place that emergency call for service. AG Heating & Cooling came out that same night. They were courteous, explained what was going, and quickly got the heat running. I have peace of mind knowing my furnace is working well and safely. - Marlene A. Thank you

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.

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.

Great service from Kevin and Ryan as always!

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!

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!

Professional, prompt, and transparent. Highly recommend

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.

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

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 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.

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.

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!

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, professional and explained everything (mouse ate cables). This company DOES NOT try to rob you with "initial inspection" fees or "service call" fees; fair priced, flat-rate charge solely based on the service issue-no hidden or additional fees (just replaced cables and did not try to up-sell me a new capacitor because current one still works). Got the job done quickly, AC working now...happy happy! Thanks again Ryan.

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.

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.

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

We recently had a new heat pump installed at our home, and we couldn't be more pleased with the experience. From start to finish, Ryan was professional, flexible, and easy to work with. His communication was top-notch—always keeping us informed, answering our questions patiently, and ensuring we fully understood the process. If you're looking for an HVAC professional who is reliable, knowledgeable, and courteous, we highly recommend ‘A G Heating and Cooling’.

I was recommended Ryan and Kevin through a mutual friend. His company, AG Heating and Cooling, is relatively new, and I was very hesitant at first. However, after speaking with Ryan and Kevin more, I realized that while their company is new, they have been doing this type of work for over a decade—just with another company. They recently decided to start their own business, and their experience and professionalism quickly put me at ease. The way they communicated and their attention to detail ultimately made me feel confident enough to award them the job. Ryan and Kevin provided me with a competitive quote for a mini-split installation and took the time to listen to my concerns. One thing I really liked about them is that they were willing to hear me out and respect my OCD-level need for everything to look clean and well-organized. A lot of contractors I looked at before them that are more well known in this type of work-wanted to route the cooling lines all over the exterior of my house with no real consideration for aesthetics. I told Ryan and Kevin that I wanted the coolant lines kept to a minimum, and the end result? They were able to get all three interior units to line up perfectly at the exterior of the house, leading to the outdoor condenser in a single, uniform line. It made for an extremely clean and professional-looking install, which I truly appreciated. I think my favorite part of this install—other than the fact that I’m saving a lot of money by converting from baseboard heaters to a ductless mini-split—is the way the lines and everything were routed. The attention to detail in keeping everything neat and streamlined made a huge difference in the overall look of the installation. Throughout the process, Ryan and Kevin were professional, knowledgeable, and communicative. They ensured everything was done efficiently without cutting corners, and the installation turned out great. If you’re looking for a reliable and skilled HVAC team, I highly recommend AG Heating and Cooling.

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.
