Question: 1 / 400

How often should an air conditioning system be serviced for optimal performance?

Once every five years

At least once a year

For optimal performance, an air conditioning system should ideally be serviced at least once a year. Regular servicing is crucial because it helps ensure that various components of the system are functioning correctly, identifies potential issues before they become major problems, and improves overall efficiency. This annual maintenance typically includes cleaning the coils, changing or cleaning filters, checking refrigerant levels, and inspecting the system for any signs of wear or damage.

By having the system serviced annually, homeowners can help prolong the lifespan of their air conditioning units, maintain better indoor air quality, and achieve more reliable comfort levels during hotter months. This proactive approach to maintenance can also lead to energy savings, as a well-maintained system operates more efficiently than one that has been neglected.
