New Britain winters put furnaces through a real workout, and once temperatures drop into the 20s and lower, a furnace that's short-cycling, blowing cold air, or refusing to fire isn't something to leave for later. Furnace repair covers diagnosing and fixing issues with gas and oil furnaces: ignition problems, faulty thermostats, clogged filters, cracked heat exchangers, blower motor failures, pilot light or igniter issues, and worn-out belts or bearings. It also includes the safety checks that matter most in an older housing stock like New Britain's, particularly carbon monoxide testing and inspecting flue and venting connections.
We list 9 furnace repair businesses serving the New Britain area. Not all of them offer the same scope of work. Some handle emergency after-hours calls, some only work on certain furnace brands or fuel types, and some are better suited to routine maintenance than a full system diagnosis at 11pm on a Sunday.
When comparing options, look for a company that's licensed to work on gas or oil systems in Connecticut, carries insurance, and gives you a clear diagnostic fee upfront rather than a vague estimate. Ask whether they stock common parts on their trucks, since a same-day fix beats a two-day wait for a part order when your heat is out. Response time, straightforward pricing, and how a company handles complaints all factor into our scoring, which you can read more about on our methodology page.
