Three summer months, and a decade of storms behind them

Boone County asks a lot of your air conditioner for just three months, June through August, with afternoons averaging 82°F. That is a short window, but the unit still has to work right the moment it turns hot.

What wears on it here is as much the weather as the heat. The county has logged 40 hail events over the past ten years, with a hailstone as large as 2.75 inches, and 37 damaging wind events in that same span. Hail dents and bends the thin aluminum fins on the outdoor coil, and a bent coil cannot shed heat the way it should. Wind drives debris into the unit or knocks it out of level, and a compressor that runs while the unit sits crooked wears faster than it should. You notice it as an AC that runs but does not cool like it used to, right when you need it most.

A new air conditioner would save little on running costs in Boone County, so the repair decision comes down to the unit's condition.

  • A new one at the federal minimum, 13.4 SEER2$180 a year
  • An older air conditioner$200 a year

Estimates for a typical Boone County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Iowa fuel prices and NOAA climate normals. Your home will differ.

Repair makes sense when a part like a capacitor or contactor has failed.

Replacement makes sense when the compressor has failed or the system uses R-22 refrigerant, which is no longer made.

Iowa requires HVAC contractors to hold a state license.

Iowa licenses HVAC contractors through the Plumbing and Mechanical Systems Board, and the license is tied to the contractor, not to any single job. That means the state tested the contractor at some point to issue that license, and it covers this contractor across every job they take on, not just the one at your house.

For an air conditioner repair, that license is the thing accountable for the work. Whoever opens the refrigerant lines also needs EPA Section 608 certification, which is federal and applies in every state, not something Iowa adds on top of its own license. Between the two, Iowa has covered both who is allowed to take on the job and who is allowed to touch the refrigerant inside it.

Why is my AC not blowing cold air?
Most often the filter is clogged and starving the system of airflow, or the refrigerant is low from a leak. A dirty filter makes the coil freeze up, and once that happens you get weak air that isn't cold. Low refrigerant is a repair only a licensed contractor can make, since it means opening the refrigerant side of the system, and that work requires EPA 608 certification. Check the filter first. If it's clean and you're still getting warm air, the problem is inside the system.
Why is my AC leaking water?
The condensate drain line is probably clogged. Your AC pulls moisture out of the air as it cools your home, and that water is supposed to run out through a drain line to the outside. When the line clogs with algae or dirt, the water backs up and drips inside instead, sometimes right at the indoor unit. A frozen coil that's now thawing will do the same thing, so if the system was blowing warm air before the leak started, that's likely the cause.
Why won't my AC turn on?
Start with the thermostat and the breaker. If the thermostat screen is blank, check its batteries. If it's on but the system still won't respond, check the breaker panel, since a tripped breaker will cut power to the whole unit. Boone gets its share of hail and wind, and a storm that knocked out power briefly can sometimes trip a breaker even after power is restored. If the breaker is fine and the thermostat is calling for cooling but nothing happens, the problem is likely electrical inside the unit itself, and that needs a licensed contractor to diagnose.
