Commercial Air-conditioning Cleaning or Repair: How to Decide

Visible dirt or a hygiene-related odour may justify cleaning. Persistent leakage, breaker trips, abnormal noise, alarms or inadequate cooling need fault assessment. Site staff should record the symptom, location and timing, without opening equipment or repeatedly restarting it.

Preparing for a Commercial Air-conditioning Cleaning Quotation

For a commercial air-conditioning cleaning quotation, start with equipment types, quantities, locations and photographs. Add ceiling height, access method, available work period, site protection and reporting needs. Site-specific information makes the quoted scope easier to compare and plan.
