Eleven months a year, your system doesn't get a break
Scott County only gives your furnace and AC about a month off, in spring and fall. The rest of the year one of them is working. Winter nights averaging 17°F mean the burner is cycling on and off for hours at a stretch, and each start puts wear on the igniter. Most homes here heat with gas, so when that igniter finally fails, the burner won't light at all.
Summer afternoons near 83°F push the other direction, running the compressor hard for three straight months. Between the two seasons the system barely rests, and storms add their own toll. Scott County has seen 170 damaging wind events and 28 winter storms over the past ten years, and across Iowa 15% of households lost power for at least a day in 2024. A hard restart after an outage is often when a weak capacitor or a failing igniter finally gives out.

A new furnace and air conditioner would cut about $120 a year off heating and cooling for a typical Scott County home.
Estimates for a typical Scott County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Iowa 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.

- Why is my heat not working?
- Most often it's the igniter, a flame sensor that needs cleaning, or the thermostat calling for heat but not getting an answer from the furnace. Check that the thermostat is set to heat and the batteries aren't dead. Check your breaker panel too, since a tripped breaker will shut the whole system down. With winter nights here averaging 17°F, a furnace that won't fire needs a contractor out soon rather than later.
- Why is my system running but not cooling the house?
- The blower could be running while the part that actually cools the air, the compressor outside, isn't kicking on. Start by checking the air filter. A filter clogged with dust blocks airflow and can make a working system feel like it's not cooling. Also look at the outdoor unit for ice on the lines or debris packed around it, both of which stop the coil from doing its job. If the filter is clean and the outdoor unit looks normal but the air coming out is still warm, that points to something like a low refrigerant charge or a failed compressor, and that's a job for a licensed contractor to diagnose.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it's set to the right mode and the temperature is actually set past the room temperature. Check the breaker panel for a tripped breaker, and check the filter, since a clogged filter can cause both heating and cooling problems. If it's a gas furnace, check that the switch on the furnace itself and any nearby service switch are both on. If none of that explains it, a licensed contractor will need to look at the system directly, and Iowa requires them to hold a state license through the Iowa Plumbing and Mechanical Systems Board.
