New Furnace Installation for Syracuse Houses
Once your Syracuse furnace job is booked through us, $100 off your first job is credited.
A furnace swap in an older Syracuse house goes wrong in two quiet ways: the size gets copied off the old nameplate, or the water heater is left alone in the chimney. Send your address and learn what to ask first.

Spec FAQ
Short answers on furnace here
| You ask | Short answer |
|---|---|
| F1 How do I know the furnace size is right for my Syracuse house? | Ask the contractor for the load worksheet. It should come from your house's walls, windows and insulation, not from the old unit. If they cannot show it, price the job again with someone who can. |
| F2 What does a Class C license limit? | In the city, a Class C residential license covers homes of up to two families and furnaces up to 200 MBH input. Ask which class your contractor holds and whether your furnace falls inside it. |
| F3 How old are Syracuse houses, and why does it matter for a furnace quote? | Syracuse city's median home dates to 1948. Of its 67,601 housing units, 85.5 percent predate 1980. Give each Syracuse contractor your house's age and ask the worksheet to reflect the windows and insulation you have now. |
| F4 Who pulls the permit for a furnace in the city? | Heating is a separate trade permit in Syracuse. Ask your contractor to name who applies for it and to put that in the written proposal. |
This fits when
Syracuse situations that call for new furnace
- The furnace is older than your kitchen If it came with the house and the house dates from the 1940s or earlier, a new one is a bigger decision than the sticker price suggests.
- A water heater vents into the same chimney Look at the pipe above your water heater. If it joins the furnace flue, the chimney is part of this job.
- You have changed windows or insulation since the old unit went in The old size was chosen for a leakier house. A like-for-like swap carries that guess forward.
- The furnace room is a closed basement closet A tight closet limits the air a gas appliance can burn, which is a question for any bid.

The old nameplate is a number, not a load
Many replacements are priced by reading the plate on the old furnace and ordering the same size. NYSERDA tells contractors to run their own sizing calculation instead, because your home may have been weatherized since the old system was sized. It also notes that many gas and oil furnaces and boilers were oversized to begin with.
Your house has probably changed since it went up, perhaps with new windows, attic insulation or siding. A furnace that is too big starts and stops all day, heats rooms unevenly and wears faster. You pay for that every winter.
Ready to compare quotes?
So ask for the Manual J worksheet and the Manual S selection in writing before you compare bids. New York's residential code calls for that method in section M1401.3. If a contractor says the nameplate is enough, hear what they say, then ask for the worksheet again.
Bring the old model number and your last gas bill to the first conversation. Neither replaces a worksheet, but they show the contractor what the house has been asking of the furnace.

The water heater left alone in the chimney
If your gas water heater shares the furnace chimney, check how each bid treats it. A condensing furnace vents out a side wall and cannot share the old flue. Oak Ridge National Laboratory calls what remains an orphaned water heater, sitting in a chimney sized to vent both appliances.
The laboratory names two fixes: a liner sized for that one appliance, or a powered draft inducer with a backflow preventer. Both add cost, and no local price is published, so do not trust a number you cannot see itemized.
Ready to compare quotes?
Ask each contractor to show you which fix they priced, and where it sits on the page.
Photograph the flue pipes in your basement before the first visit. Send them with your address, and the contractor can price the chimney line with real information instead of a guess.
Air to burn and a separate permit
Syracuse's Property Conservation Code asks that gas-fired heating equipment get air for complete combustion from outside or from open interior spaces. If your furnace sits behind a closed door in a basement corner, ask where that air comes from.
Heating is also a separate trade permit in the city. Find out from the contractor who applies for it, and keep the permit number with your paperwork. The city's Class C residential license reaches furnaces up to 200 MBH input in homes for no more than two families, so ask which class your contractor holds.
Ready to compare quotes?
Ask the contractor to settle the permit, the air and the flue on paper before the old furnace comes out.
