Efficient Heating & Cooling

Efficient Heating & Cooling is an HVAC company that says it provides heating and cooling services for residential and commercial properties throughout Fairfield County. On its Better Business Bureau page, it describes its work as the sales, service and installation of heating and air-conditioning systems. A 2025 customer said the company fixed their AC unit when another company was going to charge thousands to replace the entire system, and called the company fair and honest. A 2026 customer said the company ripped up and reinstalled the HVAC during a large renovation, and that the initial project went well but some of the work was left incomplete. That 2026 customer said it took more than 4 months to get them to come back. That 2026 customer also said the company charged a $500+ bill for 1 hour of work on the return visit, and that the communication they received when they asked about it was very short and unprofessional. It holds an active Connecticut D1 heating and cooling licence, HTG.0389393-D1, under Efficient Heating & Cooling Inc.
