What a service can include
A suitable visit may include cleaning filters, coils and condensate components; checking airflow, temperatures, controls and electrical connections; inspecting the outdoor unit and pipework; and recording anything that needs repair. The exact work depends on the system and manufacturer schedule.
How often?
Follow the manufacturer’s instructions and the needs of the premises. A lightly used domestic system may need less frequent professional attention than equipment operating daily in an office, retail, hospitality or server environment. Filters may need owner cleaning between services.
Signs not to ignore
- Reduced heating or cooling performance.
- New noise, vibration or odour.
- Water leakage or drainage problems.
- Frequent error codes or unexpected shutdowns.
- A sudden increase in energy use.
