Three months of real heat, then it stops
Davenport asks for cooling from June through August, with summer afternoons averaging 83°F. That is a short season, but a hard one, and the unit still has to be sized and installed right to carry those three months without strain.
Scott County also sees its share of hail and wind. The ten years from 2015 to 2024 brought 118 hail events and 170 damaging wind events, so the outdoor unit needs to sit where it is protected and installed the way it should be. Any new central air conditioner built since 2023 has to meet a federal minimum of 13.4 SEER2, so that's the baseline for what goes in.

Iowa requires HVAC contractors to hold a state license.
The license is held by the contractor, not issued job by job, so it is the business and the people working under it that the state has tested and put on record, not this particular installation.
For an air conditioner install in Scott County, that license is what stands behind the contractor doing the work. Most cities and counties here also require a permit from the local building office for this kind of job, with an inspection once it's done, which checks that the installation itself was done right.

- What size air conditioner does my house need?
- There's no fixed answer without a proper load calculation done on your specific house. The right size depends on your square footage, how much insulation you have, how many windows you have and which way they face, and your ceiling height. An undersized unit will run constantly and never quite cool the house on the hottest afternoons. An oversized one cools too fast, shuts off before it pulls enough humidity out of the air, and cycles on and off more than it should. A contractor will run the calculation for your house and size the equipment to match.
- Should I replace the whole system or just the outdoor unit?
- In most cases you replace both the outdoor unit and the indoor coil together. The two are matched to work at a specific capacity and efficiency, and pairing a new outdoor unit with an old indoor coil usually means the system never reaches the efficiency it was built for. It can also void the manufacturer's warranty on the new equipment. A contractor can look at the age and condition of what you have and tell you whether the indoor coil is worth keeping.
- Do HVAC contractors in Davenport need a state license to work on my home?
- Yes. Iowa requires HVAC contractors to hold a state license, issued by the Iowa Plumbing and Mechanical Systems Board. For an air conditioner installation, you'll also likely need a permit from the local building office, with an inspection once the work is done. Ask to see the contractor's license number before they start.
