Furnace replacements in Prior Lake homes

In a Prior Lake lake home, a furnace replacement is a zoning question as much as an equipment one. Walls of glass facing the water lose heat at night and gain it on sunny afternoons, vaulted great rooms stack warm air near the ceiling, and a walkout lower level stays cool from the ground. A Manual J that measures the real window area on each level tells us whether one furnace with zoning dampers or two separate systems serves the house better, and two-stage or modulating furnaces handle those swings far better than single-stage.

In the 1980s through 2000s subdivisions, it's a more ordinary job: pull the builder or first-replacement furnace, reuse or correct the PVC venting, and fix undersized returns while the plenum is open. Some older lake cabins still vent into a chimney, and a liner question follows the switch to PVC. A replacement normally needs a city mechanical permit; ask us how it shows on your quote.

Furnace replacement in Prior Lake: questions

Our Prior Lake great room has a gas fireplace. Does that affect furnace sizing?

A gas fireplace changes how the furnace runs more than how big it should be. The furnace still has to carry the whole house on the coldest night. A fireplace near the thermostat can satisfy it while the rest of the house cools off. We size the furnace by Manual J without counting on the fireplace, then look at thermostat location or a remote sensor so the fireplace doesn't fool the system.

Does a Prior Lake lake home need two furnaces or one with zoning?

Two furnaces or one zoned furnace depends on the house, not a rule. A Manual J run floor by floor shows whether one two-stage or modulating furnace with zoning dampers can hold the main floor, the great room and the walkout level together, or whether two separate systems serve them better. Two systems let each level run on its own thermostat, and one zoned furnace has less equipment to maintain. When it's close, we price both in writing.
