Furnace Replacement & Installation
in the Capital Region, NY

Most straightforward gas furnace replacements are completed in a day. Venting or fuel changes can take longer; we tell you up front.

Size comes from a heating load calculation (floor area, insulation, windows and local climate), never from a guess. Oversized furnaces short-cycle and wear out sooner, and an undersized one cannot keep up on the coldest days.

AFUE is the share of the fuel that ends up as heat in the house, so a higher rating wastes less. Whether the extra upfront cost is worth it depends on how much you heat and on fuel prices, and we compare the options for your house on the visit. Our high-efficiency heating upgrade guide explains the terms.

Furnace size, efficiency rating, venting or gas-line changes and the condition of the ductwork all move the price, so a firm number has to wait until someone has seen the house. Expect a flat written price once we have seen the house. The heating replacement cost guide explains the factors, and financing is available if you want to spread it out.

It depends on the furnace type and size, whether the vent or gas line changes and what the ductwork needs. We give a written price after seeing the house. The heating replacement cost guide lists what moves it.

A furnace commonly lasts 15 to 20 years, depending on the fuel, how hard it works and how well it has been maintained. A cracked heat exchanger or repairs that keep coming say more than the age alone. A yearly check through the maintenance plan shows how much life is left, and the signs your furnace or boiler needs replacing guide lists what to watch for.

Age, a cracked heat exchanger and repeated failures are the main signs. Our guide to the signs your furnace or boiler needs replacing covers them, and furnace repair covers fixes.

There is no single best furnace. The right one fits the size of the house, the fuel available, the ducts you have and how much you want to spend upfront against running cost. Single-stage furnaces are the simplest, two-stage and modulating furnaces run steadier and quieter, and the efficiency rating sets how much of the fuel becomes heat. The sections above explain each in plain words, and our high-efficiency heating upgrade guide covers the terms.

Yes, to all three fuels. A gas furnace swap is the simplest; oil and propane furnaces are replaced like for like, with the tank and supply line left as they are. The exception is an oil furnace on a street with a gas main, where an oil to gas conversion is worth a quote.

A dead furnace in a Capital Region winter comes first. On a weekday, 7:30am to 6pm, same-day visits are offered when the schedule allows, so call (518) 482-4205 as early as you can. If you need heat while a replacement is planned, our heating system repair page covers getting a failed system running again.

Often yes. A new indoor coil and an outdoor condenser can use the furnace blower and ducts, if the blower and ductwork can handle the airflow. We check that on the visit. See central AC installation.

It can make sense when both are old, because the indoor coil, blower and ductwork work together and a matched pair is easier to size. If only one has failed, we explain which to replace and which can wait.
