A system that works 11 months a year
Winter nights here average 14°F from December through February, and homes need heat from October through May. That is 8 months of steady runtime, and the furnace you install has to hold up through all of it. Summer is shorter but still real. Afternoons average 83°F, and homes need cooling from June through August, so the air conditioner gets its own three months of hard work right after the heating season ends.
Dakota County has seen 26 winter storms and 22 damaging wind events over the past ten years, and across Nebraska a quarter of households lost power for at least 24 hours in 2024. A new system should be able to start back up on its own once power returns, without anyone having to relight it or reset it by hand.

Nebraska requires contractors to register with the state.
That registration means the state has the business on file with the Department of Labor. Nobody tested this contractor's trade knowledge to get that record, and there's no license behind it, just a name and a business address on a state list.
For a heating and cooling installation, the real check on the work is local. In most cities and counties here, putting in a new furnace, air conditioner or heat pump needs a permit from the building office, and the work gets inspected once it's done. That inspection is what catches a bad gas connection or a system put in wrong, not the state registration.

- When should I replace my HVAC system?
- Once your furnace or air conditioner starts needing repairs every year, replacement usually makes more sense than continuing to fix it. Age matters too. A furnace or air conditioner working hard through 8 months of heat and 3 months of cooling here wears faster than one that idles most of the year. If your system is old and the repair bill keeps climbing, that's the point to start looking at new equipment instead of the next fix.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is often worth considering, but it depends on the condition of each unit. A furnace and air conditioner installed at different times may not be the same age, so one can still have years left while the other is failing. A contractor can look at both and tell you honestly whether one needs to go now or whether it makes sense to wait.
- What happens during an HVAC installation?
- A contractor removes the old furnace or air conditioner, sets the new equipment in place, and connects it to your ductwork, electrical, gas line or refrigerant lines depending on what's being installed. Once it's running, they test it and check that it's heating or cooling correctly. Replacing a furnace, air conditioner or heat pump needs a permit from the local building office, and the work gets inspected once it's done.
