Three months of heat, then years of hail and wind
Your air conditioner in Lexington only has June through August to earn its keep, but those three months push it hard. Afternoons averaging 85°F mean the compressor runs long hours to keep up, and a unit that sits idle most of the year can be slow to show a problem when it finally has to work.
Dawson County has also logged 93 hail events and 121 damaging wind events over the past ten years, with hail up to 4 inches recorded. That kind of weather bends fins on the outdoor coil and can knock the unit out of alignment or damage the fan. You may notice weaker airflow, a rattling sound outside, or the system struggling to cool the house on the hottest afternoons.

A new air conditioner would save little on running costs in Dawson County, so the repair decision comes down to the unit's condition.
Estimates for a typical Dawson County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Nebraska 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.
Nebraska requires contractors to register with the state.
That registration puts the business on file with the state Department of Labor. Nobody tested the contractor's work, and there is no license number tied to a trade exam. It tells you the business exists on paper, not that the state checked its skill.
For an air conditioner repair, the protection that matters comes from elsewhere. Any technician who opens the refrigerant side of your system, to check a charge or fix a leak, has to hold EPA Section 608 certification, and that rule holds in every state including Nebraska. That certification, not the state registration, is what says someone is qualified to handle the refrigerant in your unit.

- Why is my AC not blowing cold air?
- The most common cause is low refrigerant from a leak in the coil or line set. A dirty air filter or a coil caked with dust can also block heat transfer, so air comes out but stays warm. If the outdoor unit isn't running while the indoor blower is, that points to the compressor or a failed capacitor. A contractor who holds EPA Section 608 certification will need to check refrigerant levels, since that part of the job is federally regulated.
- Why is my AC leaking water?
- Usually the drain line is clogged, and water that should run outside backs up and drips inside instead. A frozen evaporator coil will do the same thing once it thaws, so check if the coil was iced over. In Lexington summers, running the system hard for three straight months gives algae and dirt plenty of time to build up in that drain line, so it's worth having it flushed out.
- Why won't my AC turn on?
- Start with the thermostat batteries and the breaker before assuming the worst. If those are fine, the problem is likely a tripped safety switch, a bad capacitor, or a thermostat that's lost its wiring connection. Outdoor units also shut down when debris or a storm knocks something loose, and with 121 damaging wind events recorded here over the past ten years, it's worth having someone check the outdoor unit for wind damage first.
