Furnace Replacement in Anoka, MN

A new furnace in Anoka costs $4,500–$9,500 installed with us: about $4,500–$6,000 at 80% AFUE and $6,500–$9,500 at 96–98%. In the early-1900s houses near downtown, switching to 96% often means lining the chimney for the water heater left behind, and that goes in the written quote.

Furnace replacements in Anoka homes

A furnace replacement in one of Anoka's early-1900s houses starts with the chimney. A 96% furnace no longer uses the flue, and a gas water heater left alone in a big masonry chimney often can't draft properly, so it needs a liner or a power-vent model. The PVC pipes also need a route to an outside wall that clears windows, the gas meter and the snow line. If the ductwork was sized for gravity heat, the new blower has an easy job, and a variable-speed model can run quietly at low speed most of the winter.

In the 1950s and 60s ramblers, replacements are standard basement swaps: PVC out the rim joist, and the old flue lined or capped depending on the water heater.

What affects the price of a new furnace in Anoka?

What moves the quote in Anoka: venting changes on a switch to a condensing furnace, a liner for a water heater left alone in the chimney, and ductwork and returns. See the furnace replacement cost guide.

Are there rebates for a new furnace in Anoka?

Gas comes from CenterPoint Energy, whose rebates on high-efficiency furnaces and boilers work with the dealer of your choice, a good fit for the older radiator houses near downtown. Ask us which rebates apply when we quote. Rebate programs change every year, so check the utility's current terms before you buy.

Furnace replacement in Anoka: questions

Our Anoka house has a boiler, not a furnace. Can we switch to forced air?

You can, but it's a big job. Forced air needs ducts to every room, and in a finished older house that means chasing them through closets, floors and walls. Many owners with working radiators keep the boiler for heat and add cooling separately with ductless heads or a high-velocity small-duct system. If the boiler has failed, replacing it is usually far less disruptive than converting. We'll price both if you want to compare.

Is an 80% furnace ever the better choice in an old Anoka house?

Occasionally. If there's no reasonable route for PVC pipes to an outside wall, or condensate would need a long pump run to reach a drain, an 80% furnace on a properly lined chimney can be the practical call. In most houses we find a vent path, and over a Minnesota winter the condensing furnace burns noticeably less gas.
