What a system in Davenport has to handle
Winter nights here average 17°F from December through February, and the furnace has to answer for that cold from October through May. That is 8 months of heating a year. Summer asks less of the system but still asks something. Afternoons average 83°F through June through August, and the air conditioner has to run for those three months straight.
Most homes here heat with gas, and a new furnace has to meet the federal efficiency minimum for that fuel. Scott County has also seen 28 winter storms and 170 damaging wind events over the past ten years, and about 15% of Iowa households went at least 24 hours without power in 2024. A new system should be sized and installed to hold up through what this place actually sees in a year.

Iowa requires HVAC contractors to hold a state license.
The Iowa Plumbing and Mechanical Systems Board issues that license. It covers the contractor as a business, not the specific job, so it tells you the board tested this contractor and keeps them on record, not that this particular installation was checked.
That check comes from somewhere else. In most cities and counties, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, and the work gets inspected once it is done. That inspection is what confirms this installation was done correctly, separate from whatever the state license already tells you about the contractor.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is breaking down more than once a season, or a contractor tells you the heat exchanger or compressor is failing, replacement makes more sense than another repair. Age matters too. A furnace working hard for 8 months of heating here, October through May, wears faster than one in a milder climate. If your energy bills keep climbing while the system runs longer to keep up, that is usually the unit losing efficiency, not just a cold snap.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, it usually makes sense to do them together. A furnace and air conditioner installed at different times often were not matched to work with each other. With heat needed 8 months a year here and cooling for the other 3, both systems get real use, so if one is near the end of its life the other usually is not far behind. A contractor can look at the age and condition of each and tell you whether pairing the work makes sense for your house.
- 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, gas line or electrical circuit, and the refrigerant lines if it's an air conditioner or heat pump. They check the ductwork for leaks or sizing problems since even a good furnace performs poorly on undersized ducts. Once it's running, they test it, set the thermostat, and walk you through anything you need to know. In most places here, replacing a furnace or air conditioner needs a permit from the local building office, and the work gets inspected once it's done.
