Don't Wait During Heat Waves
Why Your AC Isn't Cooling
Low Refrigerant or Refrigerant Leak
Signs: AC blows warm/mildly cool air, runs constantly, high humidity, ice on lines, hissing/bubbling noise, high energy bills
Dirty or Blocked Condenser Coil
Outdoor unit clogged with dirt/dust/leaves/debris, symptoms: warm air, weak cooling on hot days, overheating, higher electricity usage, loud operation
Frozen Evaporator Coil
Ice on indoor unit, weak airflow, warm air, water leaks when ice melts, AC running nonstop
Clogged Air Filter
Simplest and most common cause, restricts airflow and suffocates AC
Faulty Capacitor or Contactor
Electrical components wear out, causes: AC running but not cooling, weak compressor output, hard starting, loud humming, sudden shutdown
Blocked or Leaking Ductwork
Cold air never reaches rooms, symptoms: weak airflow, hot/cold spots, long cycles, high utility bills
Blower Motor Failure
Motor pushes cooled air throughout home, signs: weak airflow, little/no air from vents, loud grinding/squealing
Thermostat Issues
Sometimes thermostat is problem, not AC: incorrect settings, faulty wiring, broken sensor, battery failure, calibration issues
Dirty Evaporator Coil
Dust/debris on indoor coil blocks heat absorption, symptoms: AC cools slowly, poor humidity removal, musty odors, weak/warm airflow
Compressor Failure
Heart of system, signs: warm air, loud buzzing/clicking, tripped breaker, AC won't turn on outdoors
Electrical Problems
Faulty wiring or tripped breakers: AC not turning on, turning on but not cooling, intermittent shutdowns, burning smells
Poor Installation
Incorrectly or poorly sized systems, undersized/oversized systems, incorrect refrigerant charge, poor duct design, improper airflow setup
