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.

Furnace Replacement in Montrose, MN
For a new furnace, Montrose homes pay $4,500–$9,500 installed with us: roughly $4,500–$6,000 for 80% and $6,500–$9,500 for a 96–98% model. Montrose is on Xcel Energy for both gas and electric, so every rebate goes through one utility. We also measure static pressure, since undersized returns are common in 2000s Montrose houses.
Furnace replacement calls in Montrose homes
Montrose is replacing a generation of builder furnaces at once, and the easy mistake is a same-size swap that keeps the original return duct. Many 2000s houses here have returns too small for the blower, so a new furnace installed on them runs loud and hot and never reaches the efficiency on its label. We measure static pressure before quoting and add return capacity when the numbers call for it.
Houses with an 80% furnace vent through a metal flue shared with the water heater. Moving to a 96–98% furnace puts the furnace on PVC and can leave the water heater on a flue sized for two appliances, which has to be checked. Houses with an entry-level 90% furnace already have PVC, but the new furnace's venting tables decide whether that pipe diameter can stay. Because Xcel Energy is also the gas utility, a new furnace falls under Xcel's Heating Equipment Rebates, where some offers point to participating contractors. The mechanical permit is in the quote.

How much does a new furnace cost in Montrose?
An installed furnace from us runs about $4,500–$9,500 in Montrose: 80% AFUE roughly $4,500–$6,000, 96–98% AFUE roughly $6,500–$9,500. Same prices in Montrose as in every town we serve. See the furnace replacement cost guide.
Are there rebates for a new furnace in Montrose?
Xcel Energy supplies both gas and electricity in Montrose, so every equipment rebate comes from one utility, though each program has its own rules. Xcel's heating equipment rebates cover high-efficiency gas furnaces and point to a participating contractor. Its heat pump rebates need a Trade Partner Network contractor for ducted systems, and its residential cooling rebates cover central air. Rural addresses outside the city may be on Wright-Hennepin for electric, which runs its own heat pump rebates. Rebate programs change every year, so check the utility's current terms before you buy.

Furnace replacement in Montrose: questions
Should we move from an 80% to a 96% furnace in our Montrose house?
Usually, yes. A 96% furnace turns about 16 more cents of every fuel dollar into heat than an 80% model, and over a Minnesota winter that adds up. With us, 80% furnaces run roughly $4,500–$6,000 installed and 96–98% models roughly $6,500–$9,500. The PVC venting is a modest addition in most houses this age. The water heater's flue needs checking once the furnace no longer shares it.
What does a return-duct upgrade involve in a Montrose two-story?
Usually a second return, often upstairs, or a larger return trunk at the furnace. In many 2000s two-stories the only return is one hallway grille, and the blower can't pull enough air through it. We measure static pressure before and after the work, so you see the change in numbers instead of guessing by ear. The return work is itemized in your written quote, separate from the furnace itself.
