How Long Does a Furnace Replacement Take?
A straight furnace swap is usually done in one day. Venting changes, a chimney liner, gas line or duct work, and the permit inspection add time. What to expect.

Our furnace installs in Blaine run $4,500–$9,500, written and flat-rate: roughly $4,500–$6,000 for 80% AFUE and $6,500–$9,500 for 96–98%. Blaine gas can come from CenterPoint Energy, Xcel Energy or Centennial Utilities depending on the neighborhood, and whichever one bills you decides the furnace rebate.
The most common furnace replacement in south Blaine takes an 80% furnace off the chimney in a 1950s or 60s rambler and puts in a 96% model vented with PVC through the rim joist. That means a condensate drain to the floor drain, a vent route that clears windows and the gas meter, and a plan for the water heater, which is left alone in a chimney sized for two appliances and usually needs a liner.
North Blaine's houses, built from the 1980s on, mostly have PVC already, so their first or second replacements are cleaner. These are tighter two-stories, so a Manual J often lands smaller than the builder's furnace, and a two-stage model with a variable-speed blower helps even out the upstairs. Most of Blaine buys electricity from Connexus Energy, and its dual-fuel off-peak program is worth a look if you pair the new furnace with a heat pump.

An installed furnace from us runs about $4,500–$9,500 in Blaine: 80% AFUE roughly $4,500–$6,000, 96–98% AFUE roughly $6,500–$9,500. Same prices in Blaine as in every town we serve. See the furnace replacement cost guide.
Blaine's rebates depend on two bills. Most homes buy electricity from Connexus Energy, which offers rebates on air-source, ductless and ground-source heat pumps and central air, plus a reduced-rate program for heat pumps paired with a furnace; the rest are on Xcel Energy, whose heat pump rebates run through its Trade Partner Network. Ask whether the rebate needs a registered contractor. For gas, CenterPoint Energy customers can use any dealer for furnace rebates, while Xcel Energy and Centennial Utilities customers should check those utilities' programs. Rebate programs change every year, so check the utility's current terms before you buy.

Ask Centennial directly. Blaine's gas service is split among three utilities, and each sets its own programs. CenterPoint Energy's heating rebates, for example, are only for CenterPoint customers, so they won't apply to a Centennial address. Before we quote, we look at your bill and fill out rebate forms where the program lets us. Either way, the furnace should be sized with a Manual J and chosen for the house, not for a rebate form.
It usually stays in the chimney by itself, and that's the catch. A chimney sized for a furnace and water heater together is too big for the water heater alone, so its exhaust cools, condenses and drafts poorly, which can spill fumes and damage the masonry. The fix is a properly sized liner, or a power-vent water heater that exits through the wall. We include it in the written furnace quote so it isn't a surprise at inspection.
