Hefferon Heating & Cooling LLC

Hefferon Heating & Cooling is an HVAC company whose website lists a service area running from Danbury and Bethel out to New Milford, Southbury, Ridgefield and Wilton. It holds 4.9 stars from 424 Google ratings and an A+ grade from the Better Business Bureau. The website also advertises free estimates and 24/7 emergency service. One recent customer said Hefferon offered three AC models to choose from, then swapped the AC, evaporator and lines in one day at a reasonable price. A customer who collected estimates from five companies chose Hefferon for a full HVAC replacement and called it competitively priced. When an AC quit on the 4th of July, a customer said Hefferon was the only company that got back to them, and Freddie had the unit running again within a half hour. A recent customer said Hefferon put in a new central A/C system with new duct work, cleaned the job area after the day's work and spent a lot of time explaining how to run the system. A 2025 customer said Hefferon installed an HVAC system with ductwork from scratch and that the crew left the house spotless every day. In a 2022 review, a customer described three indoor ductless mini split units going in, with each area cleaned up before the work moved outdoors. A recent customer wrote that a technician damaged their mini-split during an appointment, that the company did not respond when they tried to schedule a repair, and that they hired another vendor to fix it. A recent customer said they waited 6 months for the company to return a filter it had taken back to clean. It holds an active Connecticut S1 heating and cooling contractor licence, HTG.0402973-S1, under Hefferon Heating & Cooling LLC.
