Connecticut rules to know
- Heating work in Connecticut requires a state license: S-1/S-2 for unlimited heating, piping and cooling, B-1/B-2 for oil and gas burners, and D-1/D-2 for warm air and air conditioning (source: portal.ct.gov)
- Replacing a furnace or boiler needs a local permit; Westport, for example, lists 'installation, replacement or extension of warm air furnaces' as requiring one (source: westportct.gov)
- The Connecticut Energy Assistance Program (CEAP) can include heating equipment repairs or replacement for households at or below 60% of state median income; for 2026-2027, apply through your local Community Action Agency from September 1, 2026 to May 31, 2027 (source: portal.ct.gov)
- Energize CT offers Energy Optimization incentives of $1,000 to $1,500 per ton to Eversource and UI electric customers who replace oil, gas, propane or electric resistance primary heat with a heat pump (source: energizect.com)

Who to call

- Your local Community Action Agency, or dial 2-1-1, to apply for CEAP heating help
- An Energize CT participating contractor if you're considering a heat pump
- Your gas utility or 911 if you smell gas or your CO alarm sounds
DIY or hire a pro?
You can check the thermostat, breaker, emergency switch, filter, and fuel level, and reset the burner once. Anything past that, including fuel lines, burners, and replacements, needs a licensed heating contractor and usually a permit.
If fixing it is more than you want to take on
A working heating system matters to buyers and to most lenders, so replacing it before listing often pays off. You can sell as-is on the open market with disclosure (the state form asks about heating system problems), but some buyers' financing may not close on a house with no heat. Selling as-is to a cash buyer is the fastest and simplest route, with no repairs, showings or financing contingencies, but expect an offer below what the house would bring after repairs.

Is there help paying for a new furnace or boiler in Connecticut?

Do I need a permit to replace a furnace in Connecticut?

What should I do if my heat goes out in winter?
Call a licensed heating contractor, keep faucets dripping, and open cabinet doors under sinks. The Connecticut Insurance Department warns that frozen-pipe damage may not be covered if you shut off the heat without winterizing.
Can I sell a house with a broken furnace?
Yes. Disclose it, since the state form asks about heating system problems. Expect buyers to ask for a price cut, and some loans may not close until heat is working.
