How Long Does a Furnace Replacement Take?

An Andover furnace replacement with us runs $4,500–$9,500 installed, whether the house burns CenterPoint gas or propane from a tank. On Connexus Energy electric, pairing the new furnace with a heat pump can open up the co-op's dual-fuel off-peak rate.
Replacing a furnace in Andover usually means one of three houses. A 1980s split-entry may still vent an 80% furnace into a chimney, and going to 96% means two PVC pipes out the rim joist, a condensate drain, and a liner or new vent for the water heater left behind. A 2000s two-story already has PVC, so the swap is cleaner, though we confirm the pipe length and diameter meet the new furnace's installation manual. An acreage home on propane gets the same condensing furnaces, set up with the manufacturer's LP conversion kit.
The newer houses are built tight, which makes Manual J sizing matter more.

By efficiency: 80% AFUE roughly $4,500–$6,000; 96–98% AFUE roughly $6,500–$9,500. See the furnace replacement cost guide.
CenterPoint's heating rebates on high-efficiency furnaces let you use the dealer of your choice as long as the application goes in the same year as the install. Ask us which rebates apply when we quote. Rebate programs change every year, so check the utility's current terms before you buy.

Usually yes, because propane typically costs more for the same heat, so every point of efficiency saves more. A 96% furnace turns 96% of the fuel into heat, against 80% for an older model, and larger rural houses burn a lot of it. Venting is the same two-pipe PVC as a gas condensing furnace. If the ducts are sound, have us price a heat pump alongside it to cut propane use further.
It turns the furnace into the backup. Under Connexus Energy's off-peak dual-fuel program, the co-op can switch your heating from the heat pump to the furnace during peak demand, and in return the heat pump's electricity is billed at a lower rate. The furnace still has to carry the coldest days, so it's sized for the full load. A two-stage 96% model suits the pairing well. Check current enrollment terms with Connexus.
