Eight months of heat, and nights that drop to 20°F
Danielson needs a furnace from October through May, eight months of the year. Winter nights average 20°F, and most homes here heat with fuel oil, so the furnace going in has to be sized for a long, cold season.
In Connecticut, 20 percent of households went at least 24 hours without power in 2024. A furnace needs electricity to run its blower and controls no matter what fuel it burns, so it is worth knowing what yours does when the power goes out. If you are installing a new gas furnace, federal rules require it to reach at least 80 percent AFUE, meaning at least 80 cents of every fuel dollar goes into heating the house.

Connecticut requires HVAC contractors to hold a state license.
Connecticut's Department of Consumer Protection tests contractors before it licenses them, then keeps a record of who holds one. The license belongs to the contractor, not to any single job, so it tells you the person or company has already been checked, not that this particular furnace install has.
For an installation, that state license is what stands behind the person doing the work. Beyond that, most cities and counties require a permit from the local building office for a furnace replacement, along with an inspection once the work is finished. That inspection is what checks the actual installation, the gas connection and venting included, rather than the contractor's history.

- What size furnace does my house need?
- It depends on a heat loss calculation, not the square footage of your house alone. A contractor works out how fast your house loses heat on a cold night, factoring in your insulation, your windows, and how the place is laid out, then matches a furnace to that number. Going bigger than what the calculation calls for isn't a safety margin, it actually makes the furnace cycle on and off more and wear out faster. With winter lows around 20°F here, getting this number right matters more than guessing high.
- How do I know it's time to replace my furnace?
- If your furnace is struggling to keep up, needs repairs more than once a season, or is old enough that parts are hard to find, it's time to start looking at replacement. Watch for uneven heat between rooms, a furnace that runs longer than it used to, or a rise in your fuel bills without a clear reason. Furnaces installed new today have to meet 80 percent AFUE at minimum, so an older unit is very likely burning more fuel or oil to make the same heat. With heat needed here from October through May, a furnace that's already struggling in the shoulder months usually won't make it through a full winter.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what you're heating with now. A high-efficiency furnace burns less fuel to produce the same heat, and with most homes here running the furnace for 8 months of the year, that difference adds up over a full season. Most homes in this area heat with fuel oil, so a more efficient furnace means fewer deliveries and less fuel burned to get through a Connecticut winter. A contractor can walk you through the actual models and what fits your house, since the right call depends on your current setup.
