Nine months of heat, ten below at night
Your furnace in Wisconsin Rapids works from September through May. On the nights that average 10°F, it runs long and often, and the igniter and blower motor take the brunt of that. When one of them wears out, you find out at night, when it's coldest and the furnace won't catch.
Summer is short here, just July and August, with afternoons around 79°F. Your air conditioner doesn't run hard for long, but it still needs to start reliably on the handful of hot days it's asked to work. Wood County has seen 25 winter storms and 47 damaging wind events over the past ten years, and storms like that knock out power. Most furnaces and air conditioners come back on by themselves once power returns, but if yours doesn't, that's worth a call.

NOAA nClimDiv, 1991–2020 normals
A new furnace and air conditioner would cut about $130 a year off heating and cooling for a typical Wood County home.
Estimates for a typical Wood County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Wisconsin 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.
Wisconsin requires contractors to register with the state.
That registration puts a contractor's business on file with the Department of Safety and Professional Services, nothing more. Nobody is tested on how to work a furnace or an air conditioner before their name goes on that list, so the record shows who they are, not what they know. Wisconsin does not let counties or cities add their own HVAC license on top of this, so the registration you find is the same one you would find anywhere in the state, Wood County included.
With no trade exam behind that registration, it is not the thing standing between you and bad work on this repair. A heating and cooling system involves gas connections and refrigerant lines, and the registration on file in Madison does not test a contractor's hand at either one. It only tells you the business is on record.

- Why is my heat not working?
- Most of the time it comes down to the thermostat, the igniter, or the power getting to the furnace. Check that the thermostat is set to heat and the temperature you've set is above the room temperature. If the furnace has a standing pilot, check whether it's lit. If the thermostat and pilot check out and the furnace still won't fire, a contractor needs to look at the igniter or the power supply to the unit.
- Why is my system running but not cooling the house?
- The blower is moving air but something is stopping that air from actually cooling, most often a dirty filter or a frozen coil. A clogged filter starves the system of airflow, and when that happens the coil can ice over and stop pulling heat out of the air at all. Check the filter first since that's the one thing worth trying before calling anyone. If the filter is clean and the air still isn't cold, the system likely needs refrigerant or has another problem a contractor has to diagnose.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set to the mode you want, heat or cool, and that the temperature you've set is actually different from the room temperature. Check the air filter next and replace it if it's gray or clogged, since restricted airflow causes a lot of problems that look like something worse. Check the breaker for the system too, since a tripped breaker looks like a dead furnace or air conditioner but takes two minutes to rule out. If those check out and the system still isn't working, a licensed contractor will need to look at it. Wisconsin requires contractors to register with the Department of Safety and Professional Services, so ask for that when you call.
