SYDNEY - s4story -- Businesses can extend the life of their air conditioner by following four maintenance practices: regular servicing, timely air filter changes, clean coils and unobstructed airflow. Like any mechanical equipment, HVAC systems need ongoing attention, and a proactive approach helps identify minor issues early, before they become major breakdowns and costly downtime.

Servicing twice a year

Air conditioning maintenance is recommended twice a year, usually just before the peak of summer and winter. During a service, a professional HVAC technician inspects the system for wear, cleans important components and carries out any repairs or adjustments needed. Checks include tightening electrical connections, lubricating moving parts, confirming the condensate drain works and verifying thermostat accuracy. The technician also assesses the system's overall condition to make sure it is ready for the coming season. Regular servicing helps the system run more efficiently, which can lower energy bills and extend its working life.

Air filters changed on schedule

Air filters trap dust, dirt and other contaminants before they reach the system and the building. As filters clog, they partially block airflow and force the system to work harder to hold the set temperature, increasing wear on components. In most commercial applications, filters should be replaced every one to three months, depending on usage and environmental factors such as air quality and contaminant levels. Regular filter changes protect the system and support indoor air quality for employees and customers.

Clean evaporator and condenser coils

The evaporator and condenser coils absorb heat from indoor air and release it outdoors. When dirt and debris build up, the coils move heat less effectively, so the system struggles to cool, uses more power and risks overheating. Coils should generally be cleaned about once a year, with the right frequency depending on the setting and surroundings. Keeping the area around the outdoor condenser unit clear of trees, shrubs, dirt and other obstructions helps prevent buildup in the first place.

Clear, unrestricted airflow

Blocked vents, ducts or air registers lead to uneven cooling and put unnecessary stress on the system. Over time, restricted airflow increases energy use, accelerates component wear and shortens the air conditioner's life. Businesses should regularly check that furniture, equipment or other items aren't blocking registers or return air inlets, and look for dust and debris in the ductwork. In some cases, professional duct cleaning is needed to remove contaminants that interfere with airflow.
