Oct 01st, 2024

Regular split system maintenance is incredibly underrated. Much like a car, motorbike or lawn mower, your air conditioner should be assessed and serviced by a professional. Getting a regular service ultimately saves you from having to get your split system repaired or replaced. In the long run, the cost of this service is little more than a drop in the ocean. 

In this guide to split system maintenance, we’re going to cover everything you need to know about the process and provide answers to some of the most frequently asked questions. Let’s get started.

Why Should I Book a Split System Service?

There are countless reasons why booking a service is a smart move. These include:

Keeping the Unit in Peak Condition: Regular servicing keeps your split system operating at its best. By addressing minor issues before they become major problems, you can maintain optimal performance and efficiency.

Avoiding Costly Issues and Repairs Down the Track: Preventative maintenance can help you avoid expensive repairs and extend the lifespan of your unit.

System Efficiency: Over time, dust and debris can accumulate, causing your system to work harder than necessary. Regular maintenance improves efficiency, which can lead to lower energy bills.

Getting Technical, Performance, and Diagnostic Checks: Professional technicians conduct thorough checks of your system’s mechanical and electrical components. They identify and address any issues, ensuring your unit is running safely and effectively.

Maintaining Product Warranty: Many manufacturers require regular servicing to keep your warranty valid. Missing scheduled services could void your warranty and leave you responsible for repair costs.

How Will I Know When to Book in a Service?

This is a fairly common question, especially if this is your first ever split system. In general, we recommend getting your split system checked annually. However, the answer depends on a variety of factors which we’ve listed below:

General Recommendations: For most split systems, an annual service is a good rule of thumb. However, if you use your system heavily or notice any issues, more frequent servicing may be necessary.

Before Summer or Winter: Scheduling a service before the peak seasons ensures your system is ready to handle the temperature extremes effectively.

Noticed an Issue (Performance or Technical): If you observe reduced cooling efficiency, unusual noises, or other performance issues, it’s time to call in a professional.

Following the Product Manual Recommendations: Check your system’s manual for manufacturer-specific advice on servicing intervals and requirements.

Higher Than Normal Utility Bills: If you notice a sudden increase in your energy bills without a change in usage, this could indicate an efficiency problem that servicing can address.

Temperature Issues or Functions Not Working: Any malfunction in temperature control or other functions should be investigated promptly to prevent further complications.

Who Can Carry Out a Split System Service?

Only specific heating and cooling specialists can provide a service. Don’t attempt to DIY or leave it in the hands of your neighbour down the street. Make sure to hire:

Licensed and Insured HVAC Professionals: Ensure the technician is licensed and insured to guarantee a high standard of work and protection for you and your home.

Technicians Familiar with Your Brand: Look for professionals who have experience with your specific brand, such as Daikin, Panasonic, or LG. They will ultimately be better equipped to handle brand-specific issues.

The Company Who Installed the Unit: If possible, have the company that installed your system perform the servicing. They are already familiar with the installation specifics and can provide consistent service.

Professional Heating and Cooling Specialists: Seek out reputable heating and cooling specialists with a proven track record and positive customer reviews.

Workmanship Guarantees, Upfront Quotes, and a Tangible Track Record: Ensure the service provider offers clear quotes and guarantees their work. A solid track record of customer satisfaction is also important.

What Does the Process Involve?

Unless specific repairs and issues need attention, a split system service will typically cover several key areas. Here’s what to expect:

Cleaning of Filters and Coils

Filters: Dust and debris can accumulate, reducing airflow and efficiency. Cleaning or replacing the filters helps your system run smoothly.

Coils: Both the evaporator and condenser coils collect dirt over time. Cleaning these coils ensures they can effectively absorb and expel heat.

Checking for Refrigerant Leaks:

Refrigerant Levels: Low refrigerant levels can indicate a leak. Technicians will check and refill refrigerant as needed while also inspecting for leaks to prevent future issues.

Inspecting and Cleaning the Condenser Unit:

Condenser Unit: Located outside, the condenser unit can accumulate debris like leaves and dirt. Regular cleaning prevents overheating and maintains efficient operation.

Testing Thermostat and Controls:

Thermostat Calibration: Technicians use advanced tools to ensure the thermostat is accurately controlling the temperature.

Controls Check: All controls, including remote and wall-mounted, are tested for proper function to ensure user-friendly operation.

Additional Checks

Inspecting Ductwork: If your split system includes ductwork, it’s inspected for leaks or blockages that could affect airflow.

Electrical Connections: Technicians will check electrical connections and components to ensure safety and prevent potential hazards.

Smart Devices: Smart technology has become a hallmark of many modern split systems. The technician servicing the unit may assess and check these components to certify that they’re still working properly.

How Long Does it Typically Take?

On average, the service may take anywhere between half an hour to 90 minutes. This will depend on the condition of the unit and how easy it is for the technicians to access the components. Here’s a rough estimate of how long each step may take: 

Initial Inspection: The technician will start with an inspection to assess the current condition of your system. This usually takes about 15 to 20 minutes and involves checking for any obvious issues or signs of wear and tear.

Cleaning and Maintenance: The core of the service involves cleaning filters, coils, and the condenser unit, as well as checking for refrigerant leaks. This part typically takes around 30 to 45 minutes (depending on the level of dirt and debris)

Testing and Calibration: Testing the thermostat and controls, and making necessary adjustments, usually takes 15 to 20 minutes. This ensures that your system is operating with precise temperature control and that all settings are functioning correctly.

What About the Warranty?

While it’s easy to leave the warranty by the wayside and forget it completely, promise when we say it’s something you don’t want to neglect! As we’ve noted below, some warranties can be void if you do not organise a service within the recommended window.

Manufacturer Warranties: Many air conditioning systems come with warranties that require regular servicing to remain valid. Check your warranty terms to understand the service requirements and avoid voiding your coverage.

Service Records: Keep detailed records of all services performed. This documentation may be required if you need to make a warranty claim.

Are There Any Measures I Can Implement Myself?

Of course, it isn’t solely the responsibility of the service technician to keep your air conditioning in peak condition. Make sure to:

Stay Within the Recommended Temperature Window: Avoid setting your thermostat to extreme temperatures. The Australian Energy Regulator suggests keeping your home between 18°C and 22°C for optimal efficiency.

Turn It Off When Not in Use: If you’re away from home for an extended period, always turn off the system to save energy. 

Use Power-Saving Modes: Many modern split systems have energy-saving modes that can help reduce electricity consumption without sacrificing comfort. This is particularly important during mild weather conditions or using the system overnight.

Look Out for Any Performance Issues: Be vigilant for any signs of trouble, such as unusual noises or inconsistent cooling. Stay on the front foot and contact us for a professional air conditioning service in Melbourne.

Be Proactive: Regularly clean the filters yourself and ensure that the outdoor unit is clear of debris. Taking these small steps can enhance the efficiency of your system between professional services.
