What Is a Communicating HVAC System, and Is It Worth It in Minnesota?
A communicating HVAC system uses a two-way data link between thermostat, furnace and outdoor unit. What it does, what it locks you into, and when it pays.

Maple Lake is a Highway 55 town platted in 1886 and settled by Irish families, sitting on the lake it's named for with a wide ring of farms, acreages and shops around it.
We repair and replace furnaces, air conditioners, heat pumps, boilers and ductless mini-splits in Maple Lake and across Wright County. Every visit starts with a $79 trip charge and a written price before any work, and the $79 is waived when you go ahead with the repair.
Inside the city the electric meter is Xcel's, while rural Maple Lake addresses are often on Wright-Hennepin; your bill tells you which.

Around town: Maple Lake · Highway 55 · Downtown Maple Lake
Book in Maple LakeMaple Lake was platted in 1886 by James Madigan, on land Irish families from County Clare had been settling since the 1850s, and the early blocks around the Highway 55 main street hold its oldest houses. Those are frame two-stories and story-and-a-halfs that most likely burned wood or coal before gas arrived, and some kept a chimney that now serves only the water heater or a wood stove. The town grew slowly and steadily, from about 780 residents in 1950 to 2,160 in 2020, so each decade added a few streets rather than one big subdivision.
That slow growth means Maple Lake has a bit of everything in small doses: 1960s–70s ramblers, 1990s split-entries and some 2000s homes. Each era brings its own equipment: chimney-vented furnaces downtown, 80% furnaces with metal flues in the ramblers, and PVC-vented high-efficiency units on the newest streets. Lake homes on Maple Lake range just as widely in age and setup.
Maple Lake's acreages run a lot of separate heaters: the house furnace, a shop unit heater, a garage heater, sometimes a wood stove. The ones that sit idle all summer are the ones that fail on the first cold morning, with a dirty burner, a spider nest in the burner tube or a flue cap knocked loose. Fire each one up in October, not December. On propane, keep the tank topped up before long cold stretches, and remember that every one of those heaters, and any furnace blower, needs electricity to run.
Homes on and around Maple Lake deal with lake humidity, and older lake houses that rely on window units or a single oversized central system often feel damp even when they're cool. A dehumidifier in the lower level, a variable-speed blower set up for dehumidification, or right-sizing the condenser at replacement fixes the clammy feeling. Detached shops and garages used as workspaces are a summer project too: a ductless head in an insulated shop cools, dries and later heats it without a flue.
In the city, CenterPoint Energy supplies gas and Xcel Energy supplies electricity. CenterPoint's furnace and boiler rebates work with any dealer you choose, and its ducted heat pump rebate applies only when the heat pump is paired with a gas furnace. Xcel handles heat pump and central air rebates for in-town homes; ask whether yours needs a registered contractor. Rural Maple Lake is often on Wright-Hennepin, which lists air-source heat pump rebates credited on the bill. Homes heated with propane or wood won't see a gas utility rebate.
Rebate programs change every year; check the utility's current terms before you buy. Our guides: Xcel and CenterPoint rebates, heat pump rebates, what happened to the federal credits.

We don't recommend it in an insulated building. An unvented heater releases all of its combustion moisture and exhaust into the shop, which is how you end up with rusty tools, dripping steel roofs and headaches. A vented unit heater, or a cold-climate ductless head in a well-insulated shop, costs more up front and avoids those problems. We size either one to the building.
The usual culprit is a thermostat near the stove: it reads 74°F and never calls the furnace while the bedrooms drop. Moving the thermostat to a hallway, or running the furnace fan on low to spread stove heat, helps. Keep the furnace on a fall tune-up anyway, because a unit that sits idle most of the winter still has to work the night the fire goes out.
No. A wood stove needs its own flue. Sharing a chimney with a gas or propane furnace or water heater can upset the draft for both, and creosote and exhaust end up where they don't belong, which is why codes don't allow it. If your stove and furnace tie into one chimney now, stop using the stove until it's sorted out. We can re-vent the furnace in PVC and leave the chimney to the stove.
A cold-climate ductless heat pump usually does. It moves heat instead of making it, so it uses much less electricity than baseboard for the same warmth through most of the winter, and it cools in summer. Keep the baseboards as backup for the coldest nights. If you're on Wright-Hennepin, check its air-source heat pump rebate before you buy.
