AC Blowing Warm Air in North NJ? Causes and Immediate Fixes

When the AC is running but blowing warm air, it is usually not a thermostat issue. In North NJ, this often shows up when systems are stressed during hot, humid weeks.

Common causes

• Low refrigerant from a leak
• Dirty condenser coils on the outdoor unit
• Tripped breaker for the outdoor unit
• Failed capacitor or contactor
• Frozen evaporator coil

What you can check

• Check the outdoor unit for power and airflow
• Replace the air filter

If the outdoor unit is not running or the air stays warm, call a pro.
