Furnace replacements in Eagan homes

Most Eagan furnace replacements are basement swaps in 1980s and 1990s homes, and the decisions are efficiency, staging and venting. A two-stage or modulating furnace with a variable-speed blower suits the city's two-stories, since long low-fire cycles even out the floors. Many of these houses already vent through PVC, and we check that its diameter and length fit the new furnace's manual, since a longer run can call for larger pipe.

Townhome closets are tighter. The new furnace has to fit beside the water heater with service clearance, and a 96% model needs a vent route through the siding plus a condensate drain, often with a pump. Associations commonly want to approve new wall penetrations. On rebates, the gas bill decides: CenterPoint Energy, Minnesota Energy Resources and Xcel Energy each offer rebates on qualifying high-efficiency furnaces under their own rules, and some programs call for a participating contractor. Replacements normally need a mechanical permit.

Furnace replacement in Eagan: questions

Can we keep an 80% furnace in our Eagan townhome closet?

Sometimes that's the practical choice. If the closet vents into a metal flue through the roof and there's no workable path for PVC through the siding, or the association won't approve one, an 80% furnace on the existing flue avoids the problem. You give up some efficiency over a long heating season. When a side-wall route is possible, we price both options so you can weigh the difference in writing.

Our Eagan house has a finished walkout. Does the new furnace need to be bigger?

Not necessarily. The buried walls of a lower level lose less heat than the floors above, while the glass on the walkout side loses more, and a Manual J counts both. Finished basements often get their heat from the same trunk as the main floor, so comfort there depends on supply and return registers as much as furnace size. Oversizing to fix a cool lower level usually just makes the furnace short-cycle.
