Split system air conditioning is one of the most popular choices for homes across the Gold Coast and Australia-wide — offering energy efficiency, zoned cooling and heating, and year-round comfort. But to keep your system running smoothly and avoid costly repairs, regular servicing is essential.So, how often should you service your split system air conditioner? Let’s dive into why servicing matters, how often it should be done, and what to expect during a routine service.

Why Regular Servicing of Your Split System Air Conditioner Is Important

Whether your split system air conditioning is used primarily for summer cooling or year-round comfort, it works hard behind the scenes to maintain a comfortable indoor environment. Over time, dust, dirt, and other airborne particles can build up in the filters and internal components, reducing efficiency and potentially causing breakdowns.

Here’s why regular servicing matters:

  • Improves energy efficiency
    A clean and well-maintained system uses less power to cool or heat your space.
  • Extends the lifespan
    Routine servicing helps your split system air conditioning last longer by preventing premature wear and tear.
  • Maintains indoor air quality
    Dirty filters can circulate dust, mould, and allergens throughout your home.
  • Prevents costly repairs
    Small issues caught early can prevent expensive breakdowns later.

How Often Should You Service Your Split System Air Conditioner?

At Domestic Air Installations, we recommend the following service schedule for your split system air conditioning unit:

Every 12 Months for Most Homes

For average households on the Gold Coast, an annual service is ideal. This allows for a thorough check before peak usage during summer or winter.

Every 6 Months in High-Use or Coastal Areas

If your split system air conditioning runs daily — especially in coastal regions like the Gold Coast where salt in the air can accelerate corrosion — a service every six months is recommended.

More Frequently for Commercial or Rental Properties

In high-use environments like rental homes, short-term accommodations, or home offices, more regular servicing (every 3–6 months) may be needed to ensure the system runs efficiently and safely.

What’s Included in a Split System Air Conditioner Service?

When you book a professional split system air conditioning service with Domestic Air Installations, here’s what’s typically included:

  • Cleaning of filters, coils, and fan components
  • Checking refrigerant levels
  • Testing electrical connections and controls
  • Inspecting for any signs of wear, leaks, or damage
  • Ensuring correct airflow and temperature control
  • Cleaning the indoor and outdoor units
  • Confirming overall system performance

Can You Clean Your Split System Yourself?

While homeowners can do basic cleaning of filters every few months (especially during peak use), it’s not a substitute for a full professional service. Only a licensed technician can check refrigerant levels, electrical components, and internal parts safely and thoroughly.

When Is the Best Time to Book a Split System Service?

The ideal time to service your split system air conditioning is during the off-season — either in spring before summer, or in autumn before winter. Booking ahead helps avoid the rush and ensures your unit is ready when you need it most.
