Common repairs
What air conditioner repair technicians fix across Ontario
AC not cooling
Low refrigerant charge, dirty evaporator coils, or a failing compressor — a licensed technician diagnoses and repairs in one visit.
Warm air blowing
Could be a tripped breaker, clogged filter, or refrigerant leak. Quick diagnosis in most cases.
AC unit frozen
Frozen coils usually indicate restricted airflow or low refrigerant. Shut it off and call — running it worsens the damage.
Strange noises
Banging, rattling, or squealing from your outdoor unit often signals a loose part or failing motor.
Water leaking inside
A clogged condensate drain line is the most common cause — typically a fast, inexpensive fix.
Short cycling
AC turning on and off every few minutes points to an oversized unit, dirty filter, or refrigerant issue.
