Avallone Heating and Cooling is a heating and air conditioning company with 5 stars from 175 Google ratings and an A grade from the Better Business Bureau, and its own site describes air conditioning installation and repair. A 2025 customer described it as a small family business of two brothers, and a recent customer called it an N. Branford business. After the fire department traced a carbon monoxide alarm to their boiler, one customer said Avallone arrived within a couple of hours, located the problem, fixed it at a very fair price and deep cleaned the boiler. A customer whose AC two other HVAC companies said could not be repaired, with replacement quotes of 15k+, said Marcello arrived in about 2 hours and repaired it for much less than replacement cost. One customer said they fixed the AC in the morning and reached out that evening to make sure it was still working, and that they said no new system was needed. A customer replacing an aging outdoor system said Avallone came in at a significantly lower price than another quote and replaced it the following day. A customer said a hot water heater was replaced within two hours. A customer said the owner/operator found and fixed the cause of a burning smell from their boiler. A customer noted they put shoe covers on every time they entered the home. A 2026 customer said Marcello and his partner installed a Mitsubishi mini split condenser and sourced a discontinued model at a reasonable price. A 2025 customer with no heat said Marcello got there in under 30 minutes, and that the furnace was cleaned and the igniter replaced. A 2024 customer said they identified a cracked refrigerant coil and searched out the part's warranty, so the replacement part was free.
Excellent Company , Excellent Service and Excellent work ethic. Marcello serviced my furnace and will be servicing my central AC in the spring. Punctual and knowledgeable. Pleasure doing business with this company!
Avallone did a great job on a tune up. Very much recommended.
Quick service when my furnace was out of commission
Great work all around. Reliable, on-time, thorough, took time to explain things; appreciate it
We had a very stressful experience recently when our carbon monoxide detector went off and we had to evacuate our home while the fire department responded. They determined that the issue was coming from our boiler, so I immediately contacted Avallone Heating and Cooling. I was extremely impressed with how quickly they responded. They were at our home within just a couple of hours of my call. From the moment they arrived, they were polite, knowledgeable, professional, and respectful of our home. They even put on shoe covers before coming inside, which was a small detail but really showed how much they cared about doing things the right way. After a thorough diagnostic, they located the problem and were able to fix it at a very fair price. I was honestly worried going into this that I might get taken advantage of — that they would recommend unnecessary parts or services and run up the bill. Thankfully, that couldn't have been further from the truth. They were completely honest and straightforward about what needed to be done and what didn't. They also did an excellent job deep cleaning our boiler and took the time to explain everything to us in detail. I never felt rushed or pressured, and I left the experience feeling confident that the job was done properly and that our home was safe. I was extremely happy with their work and have already recommended Avallone to a friend. They have definitely earned my business for all of our future HVAC needs.
