Common No-Cooling Causes
Why Your San Tan Valley AC May Run But Not Cool
Restricted Airflow
A dirty filter, blocked return, blower problem, or frozen coil can reduce airflow enough that the home stops cooling properly.
Capacitor or Electrical Failure
A weak capacitor, contactor, wiring issue, or voltage problem can keep the outdoor fan or compressor from starting correctly.
Refrigerant or Coil Problem
Low refrigerant, a leak, a dirty condenser coil, or an iced evaporator coil can all reduce heat transfer and create warm-air symptoms.
