How often should air conditioning be serviced?

Thursday 29th October 2026
For many residential systems, an annual professional service is a sensible starting point. Systems that operate extensively throughout the year, or those installed in demanding commercial environments, may require more frequent attention. There isn't a single servicing interval that's right for every air conditioning system.
The appropriate schedule can depend on:

• How frequently the system is used
• The type and size of the system
• The environment in which it operates
• Manufacturer recommendations
• Warranty conditions
• Any applicable regulatory requirements

For Toshiba equipment covered by applicable warranty arrangements, regular maintenance is particularly important. Toshiba's warranty guidance requires equipment to be regularly and properly maintained in accordance with manufacturer guidance throughout the warranty period. 

Why is regular servicing important?
During normal operation, filters, coils and other components can be affected by dust, debris and general use. A professional service gives a suitably qualified engineer an opportunity to inspect the system and identify anything that may need attention.
Regular maintenance can help support:

• Correct system operation
• Heating and cooling performance
• Airflow
• System reliability
• Applicable warranty requirements

What happens during an air conditioning service?
The exact work required will depend on the equipment and installation. A professional engineer may check the general condition and operation of the system, inspect and clean relevant components, check filters and coils and inspect condensate drainage. Where refrigerant-related work is required, this should be undertaken by appropriately qualified personnel. Toshiba's warranty guidance specifies F-Gas registered competent persons for relevant maintenance activities. 

What about commercial air conditioning?
Commercial systems may operate for longer periods or under more demanding conditions, so their maintenance requirements can differ from those of residential equipment. Larger installations may also be subject to additional inspection or refrigerant-related requirements. These are separate from routine servicing, so the maintenance requirements for each installation should be considered individually.

Don't wait for something to go wrong
Servicing shouldn't begin only when an air conditioning system stops working. If you notice a change in performance, unusual noise, water leakage or anything else that seems different from normal operation, contact a qualified air conditioning professional rather than waiting for the next planned service.

Looking after your Toshiba system
The installer or maintenance provider responsible for your Toshiba system can advise on the appropriate servicing schedule for the specific equipment and application. Understanding the maintenance and warranty requirements from the beginning also makes it easier to keep the appropriate service records throughout the life of the system.
