Eleven months of work, not three
Your furnace in Woodbury County runs from October through May, and on the nights that drop to 14°F it cycles on and off for hours trying to hold the house steady. Each start puts a load on the igniter and the heat exchanger, and that repeated cycling is what wears them out over the years. Come June, the same system switches over and works afternoons that hit 83°F, asking the compressor and the refrigerant lines to do the opposite job with barely a break in between.
Woodbury County has seen 23 winter storms and 88 damaging wind events over the past ten years, and storms like that knock out power. When the lights come back on, most furnaces and air conditioners restart on their own, but a system that was already struggling can fail right at that moment, in the middle of a cold snap or a heat spell when you need it most.

A new furnace and air conditioner would cut about $120 a year off heating and cooling for a typical Woodbury County home.
Estimates for a typical Woodbury 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.
Iowa requires HVAC contractors to hold a state license.
The Iowa Plumbing and Mechanical Systems Board issues that license. It covers the contractor, not each job, so it isn't something pulled fresh for this repair. It's tied to the person or company doing the work.
For a repair on your heating and cooling system, that license is what stands behind the contractor sent to your home. The state licenses the contractor once, and every job that contractor takes on falls under it, this one included.

- Why is my heat not working?
- Most often the thermostat is calling for heat but the furnace isn't responding, and that usually comes down to power, gas, or ignition. Check that the thermostat is set to heat and the temperature is above room temperature, then check your breaker panel and the furnace switch, which looks like a light switch near the unit. If those are fine, the igniter or flame sensor may have failed, and that's a job for a licensed contractor. At 14°F on a winter night here, a furnace that won't start needs attention fast, since the house can lose heat quickly.
- Why is my system running but not cooling the house?
- If the blower is running but the air isn't cold, the problem is usually with the refrigerant side, not the fan. A dirty filter can choke off airflow across the indoor coil enough that it ices up, so check the filter first and replace it if it's gray or clogged. If the filter is clean and the air still isn't cold, the coil may be frozen or the system may be low on refrigerant, and a contractor needs to check that. Running a system with a frozen coil can damage the compressor, so it's worth shutting it off until someone looks at it.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set to heat or cool as needed, the batteries aren't dead, and the temperature setting actually calls for the system to run. Next check the filter, since a clogged one can stop a furnace or air conditioner from working right, and check your breaker panel for a tripped breaker. If the furnace has a standing pilot, look to see if it's lit. None of this costs anything to check, and telling a contractor what you already ruled out helps them get to the actual problem faster.
