When the air conditioning quits in Ames, IA, the house tells you fast, and so does everyone in it. The most common failure we see is the humble run capacitor: a few dollars of electronics that starts the compressor and fan, weakens quietly for years, and finally lets go on a brutal afternoon, leaving the outdoor unit humming but the fan still. Right behind it come pitted contactors that no longer pass power cleanly, condenser fan motors with dry bearings, refrigerant leaks that slowly bleed the system's capacity away, and evaporator coils that ice over solid whenever airflow collapses behind a clogged filter.

Warning Signs for AC Repair
Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:
- Warm or room-temperature air blowing when the thermostat calls for cooling
- A burning smell or repeated breaker trips when the AC starts
- Bubbling or hissing noises that point to a possible refrigerant leak
- An AC that turns on and off every few minutes but never cools down the house
- Cooling bills climbing while the house stays sticky and warm
- Frost or ice forming on the copper lines or the indoor coil
- Water leaking around the indoor unit or from the ceiling below it
- Clicking or humming outside with no fan movement
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. If you notice any of these signs, call (515) 715-4159 for a prompt inspection.
