Frequently Asked Questions

An air conditioner that runs but doesn’t cool usually points to restricted airflow or a refrigerant-side issue reducing heat removal. The most common cause is a clogged filter or dirty outdoor coil that can’t shed heat; mis-set thermostats and blocked return air also reduce cooling. If the outdoor fan spins but the top of the unit feels only lukewarm, the condenser coil may be matted with debris rather than moving enough heat outside. Our technicians work in the Seattle area every day and can respond quickly, including 24/7 emergency help when cooling fully stops.

Check these quick items before scheduling service:

  • Set the thermostat to Cool, Fan Auto, and drop the setpoint by 3–5 degrees.
  • Replace a dirty filter and open supply/return vents in lived-in rooms.
  • Clear leaves and lint from around the outdoor unit; rinse the coil gently with power off.
  • Note short cycling, new noises, or warm air at vents and share photos with the tech.

Turn the system off if you see ice on the refrigerant lines to prevent compressor damage.
