Three months of hard running, ten years of storms
Your air conditioner in Ames only works June through August, and it works hard those months. Afternoons averaging 82°F mean the compressor is staying on for long stretches, not just kicking on and shutting off again. That steady load wears on the run capacitor and the contactor faster than mild weather would.
Story County has logged 113 hail events and 82 damaging wind events over the past ten years, with hail up to 2.5 inches. That is enough to bend fins on the outdoor coil or knock the unit out of level without you knowing it happened. A tune-up before summer is when a contractor checks the coil, the capacitor, and the refrigerant charge, so the months your AC has to work are the months it works right.

A tune-up checks the refrigerant charge, cleans the coils, tests the capacitor and tightens the electrical connections.
Iowa requires HVAC contractors to hold a state license.
The license comes from the Iowa Plumbing and Mechanical Systems Board, and it covers the contractor, not the visit. That means the state has tested this contractor and keeps a record of them, and that record stands behind every job they do, not just this one.
For a maintenance visit on an air conditioner, that license is what backs the person in your house. If the technician opens the refrigerant side of the system, checking charge, adding refrigerant, or working on the coil, they also need an EPA Section 608 certification, which is a federal requirement in every state. Iowa's license tells you the state has vetted the contractor. The federal certification tells you the person handling the refrigerant is qualified to do it.

- What does AC maintenance include?
- A technician checks the refrigerant charge, cleans the condenser coil outside, and tests the capacitor and contactor that start the compressor. They also check the electrical connections and confirm the system cycles on and off the way it should. Anyone touching the refrigerant side has to hold an EPA Section 608 certification, so this isn't a job to do yourself. With 113 hail events and 82 damaging wind events on record in Ames over the past ten years, it's also worth having them look over the outdoor unit's fins and cabinet for dents or damage.
- How often does an air conditioner need maintenance?
- Once a year, before the weather turns warm, is what most systems need. Ames only needs cooling from June through August, so getting it looked at in spring gives a technician time to fix anything before those 82°F afternoons arrive. A yearly check catches a weak capacitor or a low refrigerant charge before it turns into a breakdown during the hottest part of summer.
- Is AC maintenance worth it?
- Yes, because it catches small problems while they're still cheap to fix. A capacitor that's starting to weaken or a coil that's caked with dirt makes the compressor work harder, and that's what leads to a system failing on the first hot day. With only three months of real cooling weather here, a system that isn't running right doesn't get much chance to show it before you need it most.
