Three months of real heat, and hail that finds the outdoor unit
Boone County only asks a new air conditioner to work June through August, but those afternoons average 82°F and the unit has to keep up every one of those days. A system sized right for that stretch will do the job without straining through a longer season it doesn't actually face here.
The bigger risk sits outside, not in the thermostat setting. Ten years of storm records show 40 hail events and 37 damaging wind events in the area, with hail up to 2.75 inches recorded. That outdoor condenser sits exposed to all of it. Any new install since 2023 has to meet 13.4 SEER2 at minimum, and choosing equipment built to handle this area's storms as well as its summers is worth asking about before installation.

Iowa requires HVAC contractors to hold a state license.
The state tested this contractor before handing out that license, and the Iowa Plumbing and Mechanical Systems Board keeps a record of it. The license covers the contractor, not this particular job.
For the install itself, most cities and counties require a permit before a new air conditioner goes in, along with an inspection once the work is done. That inspection is what checks the install itself, separate from what the state license already tells you about the contractor.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not the square footage of your house. A contractor measures your windows, your insulation, your ceiling height, and how much shade your house gets, then works out how much heat it gains on a hot afternoon. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels damp. An undersized one runs constantly and still can't keep up when it's 82 degrees outside. Get the calculation done rather than matching whatever size is already out there.
- Should I replace the whole system or just the outdoor unit?
- In most cases you want to replace the outdoor unit and the indoor coil together. The two are matched to work at a specific efficiency and capacity, and pairing a new outdoor unit with an old coil usually means you lose the efficiency you're paying for, sometimes voiding the warranty too. If your indoor coil and ductwork are still in good shape, you likely don't need to touch the furnace or air handler itself. A contractor can check whether your existing coil will match up with new equipment before you decide.
- Do HVAC contractors in Boone 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 AC installation, you'll also need a permit from the local building office, with an inspection once the work is done. Ask to see the license before work starts, and confirm the permit gets pulled.
