| Winter (May-Jul) | Test heating function (if applicable), indoor cleaning | Less usage – good time for deep cleaning if needed |
Pro Tip: Book your spring maintenance in August or early September before the summer rush. Technicians get extremely busy from October to February, and wait times can stretch to 2-3 weeks during peak heatwaves. Maintenance contracts ensure you’re prioritised.
❌ Common Aircon Maintenance Mistakes to Avoid
Neglecting filters
Clogged filters reduce airflow, increase energy bills by 15-30%, and can cause compressor failure. Clean them monthly.
DIY refrigerant refills
Handling refrigerants without certification is illegal under F-Gas regulations and dangerous. Always use certified technicians.
Ignoring unusual noises
Rattling, hissing, or grinding may indicate mechanical wear, loose parts, or gas leaks. Address immediately.
Skipping outdoor unit cleaning
Dust, leaves, and insects block condenser coils, reducing efficiency and causing overheating.
Overlooking electrical connections
Loose wiring can cause system failure, fire hazards, and damage to PCBs. Professional checks are essential.
Waiting for breakdowns
Emergency repairs cost 2-3 times more than scheduled maintenance. Be proactive, not reactive.
Using incorrect cleaning products
Harsh chemicals can damage coils and plastic components. Use mild detergent and water only.
Not keeping maintenance records

❓ Frequently Asked Questions
How often should I service my aircon in South Africa?
Professional servicing is recommended once a year, ideally in spring before the summer heat. High-use units (running daily) or those in dusty environments like mines, industrial areas, or near construction sites may require two visits per year. Monthly DIY filter cleaning is also essential for year-round efficiency.
Can I service my aircon myself?
You can perform basic maintenance like cleaning filters, checking drainage, and wiping accessible surfaces. However, refrigerant checks, electrical components, coil cleaning, and gas handling require certified technicians due to safety and legal requirements under SAQA and DEFF regulations. DIY on these areas is illegal and dangerous.
What happens if I skip maintenance?
Efficiency drops (30-60% more electricity), energy bills rise, and your unit is at higher risk of failure. Neglected units may also void warranties, develop mold affecting indoor air quality, and fail completely during peak summer when you need cooling most. Most emergency calls we see are from units that haven’t been serviced in 3+ years.
How long does a maintenance visit take?
Wall-mounted split units: 45–90 minutes per unit. Multi-splits or commercial systems: 2–6 hours depending on complexity. A typical 3-bedroom house with 4 units takes 3-5 hours total. Technicians should provide an estimated duration when booking.
Can maintenance fix a leaking aircon?
Minor leaks from clogged drains or loose connections can be fixed during routine service (R600-1,200). Refrigerant leaks require specialized testing, leak detection, and refilling by certified technicians (R900-2,500). Regular maintenance catches drain blockages before they cause ceiling damage.
How much does maintenance cost for multiple units?
Servicing multiple units often qualifies for package rates. For example: 3–5 wall-mounted units may cost R1,800–R3,500 depending on unit size and location. This is cheaper than paying per unit individually. Always ask about multi-unit discounts when booking.
Does maintenance reduce energy consumption?
Yes, significantly. A well-serviced unit can reduce electricity usage by 15–30%, especially if filters, coils, and airflow are maintained. Dirty filters alone can increase consumption by 15-20%. With Eskom tariffs rising, this saving adds up quickly – often covering the cost of maintenance within months.
Are there legal requirements for servicing aircon in South Africa?
Yes. Handling refrigerants like R32 or R410A requires SAQA-certified technicians with refrigerant handling cards. Compliance with SANS 10147 (refrigeration safety) and DEFF refrigerant phase-down regulations is mandatory. Using uncertified technicians is illegal and can result in fines, voided warranties, and safety risks.
What’s included in a professional aircon service?
A full service typically includes: visual inspection of units, cleaning filters and coils, checking refrigerant levels and leak testing, inspecting electrical components and capacitors, lubricating moving parts, checking drainage, measuring temperature differential, and testing all functions. Always confirm exactly what’s included when booking.
Should I get a maintenance contract?
For multiple units or commercial properties, yes. Maintenance contracts (typically R2,500-8,000/year) include scheduled services, priority response, and sometimes discounted repairs. For a single home unit, annual pay-as-you-go servicing is usually fine. Compare contract options here.
