When South Africa’s weather swings from scorching summer heat to damp winter humidity, your air conditioner works overtime to keep your home comfortable. But without seasonal maintenance, even the best systems can become sluggish, noisy, or expensive to run.
That’s where a professional Air Conditioning Maintenance & Repair service makes all the difference. Our thorough seasonal care boosts performance, enhances air quality, helps prevent costly breakdowns, and extends the life of your system.”
Whether you own a ceiling cassette unit, wall split, or inverter system, these five essential seasonal tune-up tips will keep your AC running at its best all year round.
Inspect and Replace Filters
Air filters act as the system’s first line of defense—trapping dust, allergens, pet dander, and airborne pollutants. But over time, those filters clog up, making your aircon work harder than necessary.
Dirty filters restrict airflow, reduce cooling efficiency, and degrade your indoor air quality. Left unchecked, they also strain your compressor and can cause premature failure.
Pro Tip: Replace your filters every 3 months, or immediately after long periods of inactivity.
Clear and Sterilise Coils & Drains
Evaporator and condenser coils attract dust and collect moisture, especially during humid or rainy seasons. That combination creates the perfect environment for mould, bacteria, and foul odours to develop.
At Right Air, our coil sterilisation service includes flushing the system with specialised treatments and clearing the condensate drain to ensure smooth water flow and contamination-free cooling.
Clean coils and drains don’t just improve airflow—they help your AC cool faster, run more efficiently, and produce fresher, healthier air throughout your home.

Check and Correct Refrigerant Levels
Refrigerant is the lifeblood of your air conditioning system. If the charge is too low, cooling suffers. If it’s overfilled, your compressor could get damaged—leading to a much costlier repair.
That’s why our tune-ups include precise refrigerant checks and recharging to manufacturer specifications (OEM standards). This ensures your unit cools properly without overworking the system or risking leaks.
Remember: Low refrigerant isn’t just inefficient—it’s often a sign of an underlying issue, like a slow leak.
Inspect Fan Motors and Optimise Airflow
Worn-out fan motors or blocked airflow components can create hot spots, reduce cooling output, and shorten system lifespan.
During every seasonal tune-up, our technicians clean fan blades, lubricate moving parts, and measure airflow to ensure your system is distributing cool air evenly and quietly.
A well-maintained fan motor means quieter operation, better airflow, and longer-lasting equipment—especially for ceiling cassette or ducted systems that require balanced cooling across larger areas.
Electrical Safety and System Diagnostics
Loose electrical connections, worn capacitors, or frayed wires can pose both a performance risk and a fire hazard—especially during South Africa’s frequent load-shedding and power surges.
Our technicians run a full electrical safety check as part of your seasonal maintenance. We tighten connections, test capacitors and fuses, and inspect control panels for early signs of failure.
Did you know? Many AC failures during peak summer are due to capacitor breakdowns—which we can prevent with early detection and affordable replacements.
Why These Seasonal Checks Matter
Each maintenance task plays a role in your AC’s performance, but combined, they offer unmatched benefits:
- Boost energy efficiency by up to 30%
- Reduce emergency repair calls by over 80%
- Extend system lifespan by as much as 50%
- Improve indoor air quality and home safety
- Lower long-term running costs
When Should You Schedule a Tune-Up?
For best results, book your tune-up just before summer (to prepare for high usage) or after winter, especially if your unit was used for heating or sat idle.
Have a high-efficiency unit like a Samsung AR6500 or a ducted inverter system? Regular maintenance is even more important to keep your investment performing at peak efficiency.
