Frequently Asked Questions

An AC that runs but doesn’t cool usually points to an airflow or heat-transfer problem stopping the system from removing heat. The most common cause is restricted airflow from a clogged filter or a dirty outdoor coil that can’t shed heat. In many homes this is a routine issue resolved with cleaning, a fresh filter, or a small repair; replacement comes into play only when the system is mis-sized or has recurring failures. Our techs start by measuring airflow and static pressure before anything else so fixes target the real bottleneck, not the symptom. In our Sioux Falls area work, we often see spring cottonwood fluff matting onto outdoor coils and cutting capacity fast.

  • Check these quick signals before you call:
  • Filter packed with dust or supply/return vents closed
  • Outdoor unit blocked by debris or coil visibly matted
  • Ice on the refrigerant line or indoor coil
  • Thermostat set to On instead of Auto, causing warm, nonstop fan Shut the system off if you see ice to prevent damage, then restore airflow before testing again.
