The company says it has been in business for 10 years and lists a service area running from New Haven and Hamden to Madison, Derby and Cheshire. A 2024 customer said their furnace was not heating half the house; Todd arrived Monday morning, replaced some parts and was done in 2 hours. A 2023 customer said they chose Billy Carlson HVAC for a heat pump installation after getting quotes from 4 other companies, and that the installers finished the job and cleaned up afterwards. A 2022 reviewer said Billy's team installed a new boiler in their house, adding that it was not the cheapest quotation they got. A 2025 customer wrote that they called about having boiler wiring tweaked so they could install wireless thermostats, and that the worker did the thermostat install and wiring changes and confirmed everything worked. A 2025 reviewer said Billy's team came out the next day and fixed their AC in under an hour.
