Furnace Replacement in Robbinsdale, MN
For a new furnace in Robbinsdale, budget $4,500–$9,500 installed with us: roughly $4,500–$6,000 at 80% AFUE and $6,500–$9,500 at 96–98% AFUE. Gas comes from CenterPoint Energy, whose furnace rebates don't tie you to one dealer. We quote flat-rate in writing from a Manual J, ideally after the city-paid energy visit.
Furnace replacement calls in Robbinsdale homes
Replacing a furnace in a prewar Robbinsdale house is mostly about fitting new equipment to old ductwork. Big gravity-era trunks can carry a modern blower's air if the joints are sealed and the returns are adequate, but many of these houses lack enough return, so the quote often includes one or two new return runs. Old duct wrap and tape may contain asbestos, which has to be tested and, if positive, handled by an abatement contractor before we cut in.
Venting is the other half. A 96–98% furnace leaves the chimney for PVC, and the water heater left behind needs its own properly sized liner, particularly in a cold chimney on an outside wall. The postwar houses face the same venting choice with fewer duct surprises. Because the city pays for Home Energy Squad visits, sealing air leaks before the Manual J can shrink the furnace you need. CenterPoint's heating rebates require a listed furnace and an application the same calendar year. We handle the permit.

How much does a new furnace cost in Robbinsdale?
An installed furnace from us runs about $4,500–$9,500 in Robbinsdale: 80% AFUE roughly $4,500–$6,000, 96–98% AFUE roughly $6,500–$9,500. Same prices in Robbinsdale as in every town we serve. See the furnace replacement cost guide.
Are there rebates for a new furnace in Robbinsdale?
CenterPoint Energy handles the gas side in Robbinsdale and Xcel Energy the electric side. The city covers the cost of Home Energy Squad visits for residents while funds last, and in a prewar house that visit is the place to start, since air sealing and insulation change what size equipment you need. CenterPoint's heating rebates cover high-efficiency furnaces and boilers from any dealer, as long as you apply in the year of the install. Before picking an installer for an AC or heat pump, ask whether Xcel's rebate requires a registered contractor. Rebate programs change every year, so check the utility's current terms before you buy.

Furnace replacement in Robbinsdale: questions
How much can air sealing change the furnace size for our prewar Robbinsdale house?
It depends on how leaky the house was. In a 1920s or 30s house, air leaks at the attic, rim joist and old windows can be a large share of the heat loss, and sealing them lowers the load a Manual J calculates. We don't guess a percentage. If you've had the Home Energy Squad visit, share the blower door results, and we'll size the new furnace for the house as it is after the work.
Do you replace furnaces and rooftop units for shops along West Broadway in Robbinsdale?
Yes. Along with homes, we do light-commercial work: rooftop units, commercial furnaces and mini-splits for retail, offices, restaurants and multifamily buildings. The approach is the same, with a load calculation for the space, a written flat-rate quote and the mechanical permit. For a storefront, tell us what the space is used for now, since a restaurant kitchen or a salon's equipment changes the heating and cooling load more than the square footage does.
