Split system air conditioners are a dependable way to keep your home comfortable year-round, but regular maintenance is essential to ensure they perform at their best. Without proper care, your system can become less efficient, eventually leading to higher energy bills, unnecessary strain on components, and even unexpected breakdowns.

When filters and vents aren’t cleaned regularly, dust and debris can build up, making your air conditioner work harder to cool or heat your space. This not only increases energy consumption but can also shorten the lifespan of the unit, resulting in costly repairs or early replacement. By staying on top of maintenance, you can save money on running costs while keeping your home consistently comfortable.

Air quality is another important reason to prioritise upkeep. Your split system doesn’t just control the temperature—it also filters the air circulating through your home. Over time, dirty filters can trap allergens, dust, and pollutants, which may be released back into your living spaces. For households with allergy sufferers or those sensitive to air quality, this can cause discomfort. Regular cleaning and servicing keep your air fresh and healthy for everyone.

These risks highlight the importance of proper maintenance, so let’s explore how you could maintain your split system ACs and why it’s a good choice to hire professionals.

How to perform split system air conditioner maintenance

Cleaning the filters

Filters trap dust, allergens, and debris, so keeping them clean is crucial for efficient airflow and good air quality. 

  • Turn off the system, remove the filters from the indoor unit and use a soft brush or vacuum cleaner to remove dust and dirt.
  • Wash the filters gently in lukewarm water with mild detergent, then allow them to air dry completely before reinstalling.
  • Clean your filters every 3-6 months, or more often in dusty areas or during heavy air conditioner use for optimal performance.

Checking the vents

Blocked or obstructed vents can reduce airflow, forcing your system to work harder and reducing overall efficiency.

  • Inspect all air vents to ensure they’re free from dust, dirt, debris, and any obstructions that could block airflow.
  • Check for furniture or objects near vents that could block airflow and prevent your system from working efficiently.
  • Gently wipe the vents with a damp cloth to remove dirt, improving airflow and helping your system run more smoothly.

Maintaining the outdoor unit

The outdoor unit is just as important as the indoor components. Over time, dirt and leaves accumulate and affect performance.

  • Clear debris monthly around the outdoor unit to maintain airflow and ensure the system runs efficiently.
  • Keep at least a metre of clearance around the unit to prevent obstructions and allow optimal airflow.
  • Gently hose down the unit’s exterior fins to remove dirt, avoiding high pressure to prevent potential damage.

What are the benefits of regular split system air conditioner maintenance?

Regular servicing of your split system air conditioner offers several key benefits that contribute to its overall performance. Split system air conditioner maintenance helps improve energy efficiency. A well-maintained system runs more smoothly, consuming less energy to cool or heat your home, which can lower your utility bills.

Routine servicing helps identify and address potential issues before they become major problems, allowing your air conditioner to run at its best for years to come.

Regular maintenance improves indoor air quality. Clean filters and ducts prevent dust, allergens, and pollutants from circulating throughout your home, creating a healthier living environment. By investing in regular servicing, you not only enhance comfort but also protect your investment in the long term.

Why hire licensed technicians?

Hiring licensed technicians ensures the work is done safely and effectively, protecting both your air conditioning system and your home. In Australia, licensed professionals are qualified to handle refrigerants and comply with industry safety standards. By choosing a certified technician, you maintain your system’s warranty, improve its longevity, and avoid costly errors. With expert care, your air conditioner will run smoothly and efficiently, saving you time and money in the long run.
