Clinton County asks a lot of a heating and cooling system
Winter nights here average 16°F from December through February, and a new furnace has to hold a house steady against that, night after night, from October through May. That's eight months of the year it's expected to run. Summer only asks for three, June through August, with afternoons averaging 82°F, but the same system has to handle both ends without either one wearing it down early.
Most homes in the county heat with gas. Storms are part of the picture too. The area has logged 26 winter storms and 75 damaging wind events over the past ten years, and across Iowa, 15% of households went at least 24 hours without power in 2024. A furnace that comes back on by itself once power returns matters here.

Iowa requires HVAC contractors to hold a state license.
The Iowa Plumbing and Mechanical Systems Board issues that license, and it covers the contractor, not the job itself. The state tested this contractor and keeps a record of them. It does not mean a separate check happens on your furnace or air conditioner once the license is in hand.
That check comes from your local building office instead. Installing a new heating and cooling system in most Iowa cities and counties needs a permit before the work starts and an inspection once it is done. The license tells you the contractor is qualified. The permit and inspection tell you this particular installation, in your house, was done right.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is old enough that a breakdown is a real risk, not just a possibility, it is time to replace it rather than keep repairing it. Watch for repairs getting more frequent, a rise in what you pay to run it, or a technician telling you parts are getting hard to find. Homes here need heat from October through May, so a furnace that fails during those months is not a repair you want to be waiting on. If your system is still running fine and repairs have been minor, there is no reason to replace it early.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is usually the better choice. A furnace and air conditioner installed years apart often were not matched to run at their best together, and replacing one now means opening up the system again later for the other. A contractor can look at the age and condition of each and tell you whether it makes sense to do both now or wait.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, sets the new equipment in place, and connects it to your ductwork, gas or electric line, and thermostat. They will check the ducts for leaks or sizing problems, since new equipment matched to bad ductwork will not perform right. Most cities and counties require a permit for this work along with an inspection once it is done. After installation, expect the contractor to test the system through a full heating and cooling cycle before they consider the job finished.
