Heating Replacement in Connecticut

Heating Replacement for Every Connecticut Home

TMS Comfort replaces aging furnaces, boilers, heat pumps, and ductless mini-split systems for homeowners throughout Connecticut. Based in Plainville, our NATE-certified technicians help homeowners across Farmington, New Britain, Bristol, Southington, and Avon upgrade to more efficient, reliable heating, with a free on-site consultation before any work begins.

Heating Systems We Replace

Whatever’s reaching the end of its life, we’ve got a replacement path for it. Our furnace installation team swaps out aging gas, oil, propane, and electric furnaces for high-efficiency models sized correctly for your home. For homes ready to retire an old boiler, our boiler installation service handles the full upgrade, from removal to proper venting and zoning.

If you’re considering a system that heats and cools, our heat pump installation replaces outdated units with efficient, Carrier-backed systems. And for homes without ductwork or with zones that never heat evenly, ductless heating & cooling offers a replacement path that doesn’t require tearing open walls.

What to Expect During Your Heating Replacement

Every replacement starts with a free, in-home evaluation. A technician assesses your current system, home size, insulation, and fuel access, then walks you through system options and upfront pricing before you commit to anything. If you’re converting fuel types, like an oil-to-gas conversion, we’ll map out the full process, including any permitting, during this consultation.

Once you approve a system, we handle removal of the old equipment and installation of the new one, most replacements are completed in a single day, though larger conversions may take longer. We test everything before we leave and register your manufacturer warranty on your behalf.
