Nine months of heat, two of cooling, and not much rest between
Your furnace in Sheboygan County works from September through May. On winter nights averaging 15°F, it runs long stretches to hold the house steady, and the burner cycles on and off many times a day. Each cycle puts wear on the igniter and the heat exchanger. When the igniter goes, the furnace won't light at all.
Come July and August, the same system switches over and runs afternoons averaging 78°F. That is only two months of cooling, but it means the parts inside your furnace and your AC barely get a break across the year, only about one month when neither is needed. Add in the wind and winter storms this area sees most years, and a system already worn down by long runs can lose power or take a harder hit right when you need it most.

A new furnace and air conditioner would cut about $130 a year off heating and cooling for a typical Sheboygan County home.
Estimates for a typical Sheboygan 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 the business on file with the Department of Safety and Professional Services. It does not mean anyone tested the contractor's trade knowledge, because Wisconsin does not run that kind of exam. It is a record that the business exists and is registered to operate, nothing more.
Counties and cities in Wisconsin cannot layer on their own HVAC license, so that state registration is the only credential in play for this repair. On the gas side, the bad connection is the part that matters, and Wisconsin's registration rule does not include an inspection of that work.

- Why is my heat not working?
- Start with the thermostat. Check that it is set to heat and the temperature is above room temperature, since a setting bumped to cool or off will stop the furnace cold. Next check the breaker and the furnace switch, which looks like a light switch near the unit and gets flipped off by accident more often than people expect. If those are fine, look at the filter. A filter clogged with dust can choke airflow badly enough that the furnace shuts itself down to keep from overheating. Winter nights here average 15°F, so a furnace that will not fire needs attention fast, not in the morning.
- Why is my system running but not cooling the house?
- If the blower is running but the air is not cold, check the filter first. A filter packed with dust starves the system of airflow, and the coil behind it can ice over, which makes things worse the longer it runs. Look at the outdoor unit too. If it is not running while the indoor blower is, or if it is covered in leaves or grass clippings, it cannot move heat out of the house the way it needs to. Summer afternoons here average 78°F, so a system stuck like this will fall behind fast. If the filter is clean and the outdoor unit looks fine, the problem is likely refrigerant or an electrical part, and that needs a contractor to diagnose.
- What can I check before calling for HVAC repair?
- Check the thermostat settings first, since a wrong mode or a dead battery looks exactly like a bigger problem. Check the breaker box for a tripped breaker, and check any switch near the furnace or air handler that may have been bumped off. Pull the filter and look at it in the light. If you cannot see light through it, replace it, since restricted airflow causes problems in both the furnace and the air conditioner. If the outdoor unit is not running, clear away any leaves, grass, or debris around it. If none of this brings the system back, a contractor will need to look at it, and in Wisconsin they are required to register with the Department of Safety and Professional Services.
