Quick answer

If your Minneapolis home has no heat, call (612) 294-1420 now: a live person answers around the clock, a technician is dispatched from our Cahill Rd office in southwest Minneapolis, and most furnace and boiler failures are traced to an ignitor, flame sensor, pressure switch, circulator or blower that we can diagnose on the first visit.

Start here

What is going wrong tonight?

No heat

Furnace or boiler down, radiators cold, thermostat blank. Start with the emergency page for what to check before we arrive.

No heat tonight

No cooling

AC running but the house keeps warming, or the outdoor unit is silent. Capacitors, contactors and frozen coils are the usual suspects.

AC repair

Boiler trouble

Pressure dropping, one floor cold, relief valve dripping. Older Minneapolis homes run on boilers and we work on them every week.

Boiler repair

Air too dry

Static shocks, cracked woodwork and nosebleeds by February mean the house needs a whole-home humidifier sized to the furnace.

Local conditions

Why Minneapolis houses need a local read, not a national one

Roughly 43 percent of Minneapolis housing was built before 1939, and the median single-family home here dates to 1928. That changes the work. A 1920s bungalow may still run a gravity-era boiler with cast iron radiators, a 1950s rambler in the southwest suburbs usually has a forced-air furnace with undersized returns, and a 2010s infill house is tight enough to need balanced fresh air. We size furnaces for Climate Zone 6A loads, where a 2,000 square foot house often needs close to 100,000 BTU, rather than copying a national rule of thumb.

Winters here regularly reach 15 below, so the market is heating-led and the NHA VFD calendar fills from the first hard frost. Minnesota code steers most replacements to 95 percent and higher condensing furnaces, which means PVC intake and exhaust venting out a side wall, and the city charges a flat 216 dollar and 60 cent permit on a furnace change-out. We pull that permit, schedule the inspection, and complete the Xcel Energy or CenterPoint rebate forms on qualifying equipment before we leave.

Summers are short but not dry. June at MSP averages a dew point around 56 degrees and July highs climb toward 84, so an air conditioner here spends much of its effort pulling water out of the air. That is why we size cooling by load rather than by the old nameplate, and why a clean coil and a clear condensate drain matter as much as the refrigerant charge.

Warning signs

Signs it is time to call

  • Furnace runs but the air from the registers is cool, or it lights and shuts off within seconds.
  • A blinking code on the furnace board, a boiler pressure gauge near zero, or a relief valve dripping.
  • Carbon monoxide alarm sounds, or soot appears around the burner door or water heater hood.
  • One room is always several degrees colder than the rest, even with the vents wide open.
  • Water on the floor around the furnace, or ice on the copper line going into the AC coil.
  • Squealing, grinding or banging when the system starts, or a burning smell that does not fade.

How a job runs

What happens after you call

  1. 1

    Call and describe the problem

    A person answers at any hour. Tell us what the system is doing, and we will say what to check while a truck is on the way.

  2. 2

    Diagnose before quoting

    The technician tests the failed part, checks the heat exchanger or coil, and shows you the reading before any price is discussed.

  3. 3

    Repair or size a replacement

    Common parts ride on the truck. If the unit is past saving, we run a load calculation instead of matching the old nameplate.

  4. 4

    Permit, install, inspect

    Replacements get a Minneapolis mechanical permit and a city inspection, plus the rebate paperwork for qualifying equipment.

  5. 5

    Walk you through it

    Filter size, thermostat settings, humidifier setting for a sub-zero week, and what to watch for next season.

Before you book

What rides on the truck, and what we put in writing

Parts for the common failures

Hot surface ignitors, flame sensors, pressure switches, run capacitors, contactors and universal blower motors travel on the truck, so a first-visit fix is normal rather than lucky.

A load calculation, not a nameplate copy

A replacement furnace or AC is sized from the house: square footage, insulation, window area and duct capacity. Oversized equipment short cycles and wears out early.

Permit and inspection on every replacement

The Minneapolis mechanical permit is pulled in our name, the inspection is scheduled, and the sign-off goes in your file for resale.

Rebate forms completed for you

Xcel Energy and CenterPoint rebates on 95 percent and higher furnaces and cold-climate heat pumps are filed by us with the model and serial numbers already entered.

Boilers treated as boilers

Steam and hot water systems get a technician who knows near-boiler piping, expansion tanks and radiator balancing, not a furnace tech improvising.

A written diagnosis before a price

You see the failed reading, the part number and the repair cost before saying yes. If replacement makes more sense, we say why and give both numbers.
