Common issues
What AC problems do London, ON contractors fix?
AC not cooling
Low refrigerant, dirty evaporator coils, or a failing compressor — a technician can diagnose and repair in one visit.
Warm air blowing
Could be a tripped breaker, a clogged filter, or a refrigerant leak. Quick fix in most cases.
AC unit frozen
Frozen coils usually mean restricted airflow or low refrigerant. Shut it off and call — running it makes it worse.
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.
