Furnace Replacement in Mahtomedi, MN
A new furnace in Mahtomedi runs $4,500–$9,500 installed with us, and many jobs also fix the last swap's badly pitched PVC or stranded water heater. Remodeled lake homes often need a smaller furnace, sized by Manual J in a written quote.
Furnace replacements in Mahtomedi homes
Many Mahtomedi houses have already gone through one furnace swap, so the replacement job often means cleaning up after the last one: PVC that was never pitched right, a condensate line strung across the basement to a distant floor drain, or a water heater left in a chimney sized for two appliances. A new 96–98% furnace gets its own properly sized intake and exhaust, a trap and drain that won't freeze or clog, and a liner or power-vent answer for the orphaned water heater.
Sizing is the other half. Lake homes that were remodeled, reinsulated or rebuilt around an old cottage have loads nothing like their original equipment, and a Manual J often lands on a smaller furnace with two-stage or modulating burners. For the rebate, Xcel Energy's heating equipment program is the one that applies here; ask whether the rebate needs a registered contractor. A furnace swap in Mahtomedi normally needs a city mechanical permit.

Furnace replacement in Mahtomedi: questions
We're moving from an 80% furnace to a high-efficiency one in our older Mahtomedi house. What happens to the water heater?
It may need its own fix. Once the furnace vents through PVC, the water heater becomes the only appliance in a chimney flue sized for two, and a lone water heater often can't keep that flue warm enough to draft well; condensation can also damage the chimney. The usual answers are a properly sized liner or a power-vent water heater. We check the chimney during the quote and include the fix in writing.
Our Mahtomedi lake home was remodeled and reinsulated. Should the new furnace be smaller?
Probably. New windows, insulation and air sealing can cut the heat loss well below what the original furnace was sized for, and an oversized furnace short-cycles, wears faster and leaves the house swinging between warm and cool. A Manual J based on the house as it is now sets the right size. A two-stage or modulating furnace then runs long, gentle cycles that suit a tighter home.
