Eleven months of work a year, and not much room for error when it fails
In Dawson County your furnace and your air conditioner both put in long hours. Heat runs October through May, eight months. Cooling picks up June through August. That leaves only one real month off, and most systems don't get much of a break before the next season leans on them.
Winter nights here average 16°F, cold enough that a furnace cycles on and off all night to hold the house steady. Each cycle is wear on the igniter and the heat exchanger. Summer afternoons average 85°F, and an air conditioner running that hard for three straight months puts real strain on the compressor. Add in the wind. Dawson County has logged 121 damaging wind events and 17 winter storms over the past ten years, and almost half of homes here heat with electricity, so when the power goes out, the furnace goes with it. Statewide, a quarter of households lost power for at least a day in 2024. If your system won't start back up, or it's been struggling to keep the house at temperature, that's what it's been dealing with.

Nebraska requires contractors to register with the state.
That registration puts the business on file with the Department of Labor. It does not mean anyone tested the contractor's work or graded their skill against a trade exam. Nebraska keeps a record of who is operating, not a measure of who is good at the job.
For this repair, the registration is the only state-level check there is. Nebraska has no license and no state exam standing behind the work on your furnace or air conditioner. The record on file with the state says the business exists and nothing more.

- Why is my heat not working?
- Start with the thermostat. Make sure it's set to heat and the setpoint is above room temperature, since a setting bumped by accident is common. If that's not it, 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 ignite at all often has a bad igniter or a flame sensor that needs cleaning, and either one is a job for a contractor. With winter nights here averaging 16°F, it's worth getting this looked at quickly rather than waiting.
- Why is my system running but not cooling the house?
- The most common cause is a dirty air filter choking off airflow, so check that first and replace it if it's gray or clogged. If the filter is clean, look at the outdoor unit and clear away any leaves, grass clippings or debris blocking the coil. A system that runs constantly but never gets the house cold may be low on refrigerant, which means a leak, and that needs a contractor to find and fix. Running a low system for long stretches can damage the compressor, so don't wait too long to get it checked.
- What can I check before calling for HVAC repair?
- Check the thermostat first, including the batteries if it has a screen that's blank or dim. Check that the system has power, both at the breaker and at any local disconnect switch near the unit. Look at the air filter and swap it if it's dirty, since restricted airflow causes problems in both heating and cooling. If the outdoor unit is involved, make sure nothing is blocking it. If you've checked these and the system still isn't working right, a contractor will need to diagnose it further.
