Heating Installation in Connecticut

Heating Installation for Every Connecticut Home

TMS Comfort installs new furnaces, boilers, heat pumps, and ductless mini-split systems for homeowners throughout Connecticut. Based in Plainville, our NATE-certified technicians handle heating installations for homes across Farmington, New Britain, Bristol, Southington, and Avon, matching each system to your home’s size, layout, budget, and efficiency goals, whether you’re replacing an aging unit, converting fuel types, or heating a new addition for the first time.

Heating Systems We Install

Not every Connecticut home heats the same way, and we install every major system type. Furnaces remain the most common choice; we install gas, oil, propane, and electric models built for the region’s cold winters, sized correctly for your square footage and ductwork. For homes with radiators or radiant floor heating, our boiler installation covers gas, oil, and propane systems with attention to proper venting and zoning so every room heats evenly.

As a Carrier Factory Authorized Dealer, our heat pump installation provides efficient heating and cooling in one system, a popular choice for homeowners looking to reduce reliance on fossil fuels. For additions, older homes without ductwork, or rooms that never quite get warm enough, ductless heating & cooling heats and cools individual zones without the cost or disruption of installing new ducts.

Signs It’s Time for a New Heating System

  • Your system is more than 15 years old
  • You’re scheduling repairs more than once a season
  • Your energy bills keep climbing with no clear explanation
  • Some rooms never get warm enough, no matter the setting
  • Your system uses outdated parts that are hard to find
  • You’re renovating or adding square footage that needs more heating capacity
  • You’re switching fuel types, like converting from oil to gas
  • Your current system requires manual workarounds just to keep it running

What to Expect During Your Heating Installation

Every installation starts with a free, on-site consultation. A licensed technician evaluates your home’s size, insulation, existing ductwork or piping, and fuel access, then walks you through system options and gives you an upfront estimate before any work begins. Once you approve a system, we schedule the installation at a time that works for you; most are completed in a single day, typically four to eight hours, though oil-to-gas conversions or multi-zone ductless installations may take longer.

Our technicians handle everything from removing the old equipment to sizing, connecting, and testing the new system, so it’s running safely before we leave. We’ll also walk you through your new thermostat, answer any questions, and register your manufacturer warranty so you’re covered from day one.
