Why Is My Air Conditioner Running But Not Cooling Properly?

Your AC can run but not cool due to a dirty filter, wrong thermostat mode, iced coils, low refrigerant, or a failed fan. Start with quick checks, then book service. We service all makes and models in Jacksonville and St. Augustine. Our maintenance plan reduces breakdowns and includes a 10% repair discount and no overtime charges.

  • Set thermostat to Cool and 3–5°F lower.
  • Replace or wash the filter.
  • Clear leaves from the outdoor unit.
  • If ice is present, turn system off to thaw, then call.

"When my AC suddenly stopped working, Creeks responded to my call at 5PM on a Sunday night and were out here 2 hours later to fix my unit." — Michelle O.
