Furnace replacements in Orono homes

Big Orono houses usually split their heating load across two or three furnaces, and each gets its own Manual J for the area it serves. The upstairs system faces vaulted ceilings and lake-facing glass; the basement system may share the lower level with in-floor heat, which changes how much forced air it needs. Sizing each one to its zone, and wiring the thermostats so they don't overlap, fixes more comfort complaints than bigger furnaces do.

Attic or upper-floor furnaces need condensate lines protected from freezing and a secondary pan with a float switch. For detached garages and guest houses, the choice is a new vented unit heater, a small furnace, or a ductless heat pump if the building also needs cooling. Outbuildings on propane stay on propane unless a gas line is close. CenterPoint Energy supplies gas to most of Orono. The city normally requires a mechanical permit for the install; the written quote says whether this job needs one.

What affects the price of a new furnace in Orono?

What moves the quote in Orono: venting changes on a switch to a condensing furnace, a liner for a water heater left alone in the chimney, and ductwork and returns. See the furnace replacement cost guide.

Are there rebates for a new furnace in Orono?

Orono homes are on CenterPoint Energy gas and Xcel Energy electricity, so both utilities' programs apply. CenterPoint's heating rebates cover high-efficiency furnaces and gas boilers, including boilers that drive in-floor heat, plus smart thermostats, and you can use any dealer. 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 Orono: questions

Should we replace all the furnaces in our Orono house at once?

Not necessarily. If they went in together and are all about the same age, replacing them together keeps controls and warranties aligned and means one permit process. If one is much newer, replace the old ones and keep the good one. Each furnace gets its own written price, so you can phase the work over a couple of years if that suits you better.

Does the lake-facing glass in our Orono house change furnace sizing?

Yes, a lot. Big windows lose more heat at night than insulated walls, and on sunny winter days they gain heat, so rooms facing the lake swing more than the rest of the house. A Manual J counts the actual glass area and orientation. A two-stage or modulating furnace handles those swings better than a single-stage one sized only for the coldest night.
