Heat that holds at twenty below.
Furnaces, boilers and cold-climate heat pumps for Minneapolis and the inner-ring suburbs, from a South Side family company that has spent thirty-seven winters keeping old houses warm.
What your heat is doing at each step down.
Most heating problems show up on the way down the thermometer, not at the bottom. Here’s what happens at each step, and what’s worth doing about it.
Your systemFurnace or heat pump, either one
Heat pumpsComfortable. Barely working.
What to doChange the filter. Book the fall check.
Your systemA cold-climate heat pump is still efficient
Heat pumpsOlder heat pumps start leaning on backup heat
What to doCheck the outdoor unit isn’t buried by the plow.
Your systemFurnaces and boilers run long cycles
Heat pumpsCold-climate heat pumps still deliver most of their rated heat
What to doKeep the furnace intake and exhaust pipes clear of snow.
Your systemClose to the design day most Minneapolis systems are sized for
Heat pumpsMany heat pumps now share the load with backup heat
What to doCracked heat exchangers and failed igniters show up here.
Your systemYour heating system at its limit
Heat pumpsA furnace or boiler as backup earns its keep
What to doIf the heat goes, call. Pipes on exterior walls freeze within hours.
Three ways to keep a house warm.
Furnaces
Most of the houses in the city. Tune-ups, igniters, heat exchangers, and high-efficiency replacements sized properly.
Furnaces →
Boilers
Hot-water and steam, the quiet heat of old Minneapolis. We keep them running for decades and replace them only when it’s time.

Cold-climate heat pumps
They work here now. We’ll tell you honestly whether yours should run alone or with the furnace as backup.
Heat pumps →Should a Minneapolis house go all heat pump?
Sometimes. Cold-climate heat pumps keep delivering heat well below zero, and plenty of houses here run on one alone. But not every house should, and we’d rather say so than sell you the wrong system.
Well-insulated house, newer windows, ducts in good shape, and you’re comfortable with electric resistance backup on the coldest nights.
Your furnace is under ten years old, or the house is drafty, or you want the gas furnace to take over below a set temperature. Most of our installs.
Radiator heat in an old house. A heat pump can add cooling and shoulder-season heat, but the boiler stays for January.
Your furnace is three years old and works fine. Wait. We’ll still be here.
Checked in October. First in line in January.
- Fall heating check with a combustion test and CO reading
- Spring cooling check if you have AC or a heat pump
- Priority on the no-heat line from November to March
- No after-hours fee, ever
- 10% off repairs
Said in January.
“Called at ten at night, minus eighteen. Erik had the igniter replaced by midnight. We’re on the season plan now.”
“Three companies wanted to rip out our 1950s boiler. Lindqvist cleaned it, replaced a circulator, and told us it has years left.”
“They talked us into keeping the furnace as backup for the heat pump. Last February we were glad they did.”
The cold-climate heating site, built in seven days.
Sixteen pages: a live outdoor-temperature ladder, an honest cold-climate heat pump page that says when to keep the furnace, and a no-heat line that leads every page from November to March.
