Troubleshooting
AC Blowing Warm Air? 7 Causes and What to Do
An AC that blows warm air is most often caused by a wrong thermostat setting, a clogged air filter, a tripped breaker for the outdoor unit, or a dirty outdoor coil. If those check out, the likely cause is a failed capacitor or contactor, or a refrigerant leak, and those need a licensed technician.

AC Frozen? Ice on the Lines or Coil: Causes and Fixes
An AC freezes when the indoor coil gets too cold, usually from low airflow (dirty filter, closed vents, weak blower) or low refrigerant from a leak. Turn cooling off and run only the fan to thaw it, replace the filter, and if it freezes again, call a technician to check airflow and refrigerant.

AC Leaking Water Inside the House? Causes and Fixes
An AC leaking water indoors is usually caused by a clogged condensate drain line, a cracked or rusted drain pan, or a frozen coil that is melting. Turn the system off, check the drain line and float switch, and call a technician if the pan is damaged or the leak continues.

Common problems and what they mean
Light blinking, unit stopped
An error code. Count the blinks or note the code before you reset it.
Water dripping from the head
Clogged drain line or a failed condensate pump.
Blows air but not cold
Dirty filters and coil, a sensor problem or a refrigerant leak.
Musty smell
Mold on the blower wheel. Needs a proper deep clean.
Pro tip
Mini-split filters clog fast. Rinse them every 2 to 4 weeks in summer and most problems never start.
