Step 1 of 3: Equipment

Nine months of heat, three of cooling, and not much room to spare

Your furnace in Stearns County works from September to May. On the nights that drop to 6°F, it runs long and often, and every cycle puts wear on the igniter and the ignition control. When one of those fails on a cold night, the house cools fast because there is no mild weather outside to buy you time.

Summer asks less of the system here, three months of afternoons near 79°F, but the air conditioner still has to keep up on the hottest days. Add in the wind and winter storms this county sees most years, and it is common for power to drop out for a stretch. When it comes back, a gas furnace with standing pilot will relight on its own, but a furnace with an electronic igniter usually needs a reset or a cycle before it fires again.

A new furnace and air conditioner would cut about $140 a year off heating and cooling for a typical Stearns County home.

  • A new furnace and AC$670 a year
  • An older furnace and AC$810 a year

Estimates for a typical Stearns County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Minnesota fuel prices and NOAA climate normals. Your home will differ.

Repair makes sense when one part has failed.

Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.

Minnesota has no state license for HVAC contractors.

There is no state license and no state registration for this kind of work in Minnesota. The state does not test HVAC contractors, does not grade them, and keeps no list of who is qualified to repair a heating and cooling system. Whatever protection a homeowner has here does not come from the state.

That means nothing at the state level stands behind this repair. No license is checked, no state registration is on file, and no state board hears complaints about the work. Minnesota simply has no state-level check on who does this job.

Why is my heat not working?
Start with the thermostat. Check that it's set to heat and the temperature is set above the room temperature, and check the batteries if it has a screen that looks dim. If the thermostat looks fine, check your breaker panel and any switch near the furnace that looks like a light switch, since that cuts power to the unit. A furnace that won't light at all is often the igniter or the flame sensor, and those need a contractor to test and replace. At 6°F on a winter night here, a furnace that's short cycling or blowing cold air shouldn't wait.
Why is my system running but not cooling the house?
Check the air filter first. A filter clogged with dust blocks airflow across the coil, and the coil can ice over, so the system runs but the air coming out feels weak or warm. If the filter is clean, check the outdoor unit and clear away any leaves, grass clippings or debris sitting against it, since it needs open airflow to release heat. If the outdoor fan isn't spinning, or you hear the system running but feel no air at the vents at all, that points to something inside the system a contractor needs to look at, like a failing capacitor or a refrigerant leak.
What can I check before calling for HVAC repair?
Check the thermostat settings and batteries first, since a wrong setting or a dead battery looks exactly like a broken system. Check the breaker panel for a tripped breaker, and look for a power switch near the furnace or outdoor unit that may have been bumped off. Check the air filter and replace it if it's visibly dirty, since restricted airflow causes both heating and cooling problems. If the system still isn't working after that, a contractor will need to diagnose it, and telling them what you already checked helps them get to the problem faster.
