AC Maintenance Guide: What to Check and When Repair Is Needed
What is the difference between AC maintenance and repair?
Maintenance periodically checks preventable buildup, drainage, airflow, pipework and operation. Repair diagnoses and addresses a specific fault after it appears. They complement each other, but maintenance cannot guarantee that no fault will occur.
What maintenance records should include
- ✓Operating environment
Record long operating hours, grease, humidity or high occupancy.
- ✓Symptoms
Record leaks, odors, noise, trips or changing cooling.
- ✓Work completed
Keep cleaning, inspection, quotation and parts records.
Common questions
Does an AC need maintenance when no fault is visible?
Preventive checks can be scheduled by use and environment to identify buildup, drainage or pipework concerns earlier; they do not promise that failures cannot occur.
