Furnace Replacement in Deephaven, MN
Furnace replacement in Deephaven costs $4,500–$9,500 installed, quoted flat-rate and in writing after a Manual J. Moving off the old chimney means planning a PVC route away from the windward lake side.
Furnace replacements in Deephaven homes
Replacing a furnace in a 1930s–1950s Deephaven house usually means a decision about the chimney. A 96–98% furnace vents through PVC, which frees it from the old flue but strands the water heater in a chimney built for two, and that water heater then needs a liner or a new model that vents itself. Finding a PVC route on a lake lot takes care: the termination should stay off the windward lake side, away from decks and windows, and above the snow line.
Sizing deserves the same care. A house that has been insulated or re-windowed since it was built needs less furnace than the old nameplate suggests, and the lake side takes more wind than the street side, so a room-by-room Manual J beats copying the old unit. Where part of the house runs on a boiler, we can replace the furnace alone or plan both together.

CenterPoint pays rebates on high-efficiency furnaces and on boilers, useful where an older house still runs on hot water, with the installer of your choosing and an application filed the same calendar year. Ask us which rebates apply when we quote. Rebate programs change every year, so check the utility's current terms before you buy.

Furnace replacement in Deephaven: questions
Where can the PVC vent pipes go on our Deephaven lake house?
Usually out the side wall nearest the furnace, but on a lake lot the details matter. The terminations must sit the manufacturer's required distance from windows, doors, decks and the gas meter, stay above expected snow depth, and ideally avoid the side that takes wind straight off the lake, where gusts can upset combustion. If no wall works, some furnaces can vent up through an unused chimney used as a chase.
Would a modulating furnace even out the drafty lake-side rooms in our Deephaven house?
Often, yes. A single-stage furnace only knows full blast and off, which makes lake-facing rooms swing between warm and cool on windy days. Two-stage and modulating furnaces spend most of their time at low fire with the blower moving air slowly and steadily, which evens out drafty rooms and runs quieter. They cost more, and the difference shows most in houses with uneven rooms like these.
