(standard residential installation)
These prices include standard installation as defined below. Always verify what’s included in your quote – some aircon installers near me may offer lower rates but exclude essential items like copper piping or electrical isolation.
🧊 What Is Included in Standard Installation
When you request a quote from professional aircon installers, standard installation typically includes:
- Indoor unit wall mounting
- Outdoor unit bracket installation
- 3 metres copper piping (standard)
- Electrical interconnection cable
- Drain pipe installation
- Vacuum pump evacuation
- Refrigerant gas charging
- System testing and commissioning
- Basic user training
Installation must comply with SANS 10147 safety standards for refrigeration systems. Certified installers will ensure your system meets these requirements, protecting your warranty and ensuring safe operation.
📊 Split Aircon Installation Price by Room Size
The size of your room determines the BTU (British Thermal Unit) capacity you need. Installing the correct size is crucial for efficiency, comfort, and electricity consumption. Here’s what you can expect to pay for different room sizes.
🛏️ Bedroom Installation Cost
| Room Size | Recommended BTU | Total Installed Cost | Example Areas |
|---|---|---|---|
| 12–18m² | 9000 BTU | R6,500 – R11,000 | Small bedrooms, home offices |
| 18–25m² | 12000 BTU | R7,500 – R13,500 | Master bedrooms, guest rooms |
9000 BTU and 12000 BTU installations are the most common in South African homes. Johannesburg and Pretoria see the highest volume due to extreme summer heat.
🛋️ Lounge Installation Cost
| Room Size | Recommended BTU | Total Installed Cost | Typical Applications |
|---|---|---|---|
| 25–35m² | 18000 BTU | R12,000 – R18,000 | Open-plan lounges, dining areas |
| 35–50m² | 24000 BTU | R18,000 – R30,000 | Large lounges, entertainment areas |
For larger spaces, consider whether one larger unit or two smaller units would work better. Split vs ducted aircon comparisons can help you decide the best approach for open-plan living areas.
Pro Tip for Homeowners: Don’t oversize your aircon thinking it will cool faster. An oversized unit short-cycles, wastes electricity, and doesn’t dehumidify properly. Use our aircon sizing BTU calculator to get the exact size for your room. Local Sandton aircon specialists can also do free site inspections to confirm requirements.
🔧 Labour Cost Breakdown for Aircon Installation
Labour costs vary significantly based on installation complexity. Understanding these differences helps you evaluate quotes accurately and avoid surprises. Here’s what local aircon installers typically charge for different scenarios.
| Installation Type | Labour Cost | Description | Typical Duration |
|---|---|---|---|
| Back-to-back | R1,500 – R2,500 | Indoor and outdoor on same wall | 2-3 hours |
| Standard installation | R1,800 – R3,500 | Up to 5m pipe run, ground floor | 3-4 hours |
| Long piping installation | R3,000 – R6,000 | 5-15m pipe run, additional labour | 4-6 hours |
| Double-storey installation | R3,500 – R7,500 | Second floor, scaffolding often required | 5-8 hours |
What Affects Labour Cost?
Distance between units: Longer pipe runs = more labour and materials
Wall type: Concrete or brick walls take longer than drywall
Accessibility: Second-storey installations need scaffolding (R3,000-8,000 extra)
Electrical requirements: New circuits add time and cost
Roof type: Tile vs corrugated iron affects outdoor unit mounting
Obstructions: Cupboards, beams, or limited space increase difficulty
Always ask for a detailed breakdown when comparing quotes from Pretoria aircon installers or specialists in your area. Some may quote lower labour but charge more for materials.
🧱 Back-to-Back vs Extended Installation Cost
The placement of your indoor and outdoor units is the single biggest factor affecting installation cost. Here’s how the two main configurations compare.
Back-to-Back Installation
Cheapest option
Indoor and outdoor unit placed on the same wall, directly opposite each other. The pipe run is minimal (typically under 1 metre).
Cost: R1,500 – R2,500 labour
✓ Minimal pipework
✓ Fastest installation
✓ Lowest labour cost
✗ Not always possible due to wall layout
Extended Installation
Outdoor unit placed away from indoor unit – around corners, across rooms, or on different sides of the building.
Cost: R3,000 – R7,500 labour
✗ Longer pipe runs (extra cost)
✗ More trunking required
✗ Longer installation time
✓ Necessary for many townhouses and apartments
⚠️ Important: Many quotes assume back-to-back installation. If your installer arrives and finds extended installation is needed, they may charge extra on the spot. Always confirm the configuration during the site inspection and get it in writing. Free inspections are available from certified installers in your area.
📏 Copper Pipe Cost Per Metre and Electrical Installation
Most installers include only 3 metres of copper piping in their base price. Additional piping is charged per metre and can significantly increase your total cost if the units are far apart.
Additional Piping Cost (Beyond 3 metres)
| Item | Price Per Metre | Notes |
|---|---|---|
| Copper pipe (pair) | R250 – R450 | Includes insulation, both liquid and suction lines |
| Trunking / ducting | R150 – R300 | Conceals pipes, colour-matched available |
| Electrical cable | R80 – R150 | Interconnection cable between units |
| Drain pipe | R50 – R120 | Insulated drain line for condensate |
⚡ Electrical Installation Cost
Air conditioners require a dedicated power supply with an isolator switch at the outdoor unit. This is often a separate cost not included in standard installation quotes.
| Electrical Item | Cost | Requirements |
|---|---|---|
| Isolator switch | R600 – R1,200 | Required within 2m of outdoor unit |
| Dedicated breaker | R800 – R2,000 | In distribution board, separate circuit |
| Electrical labour | R800 – R2,500 | Running cable, installation, testing |
| Surge protection | R1,500 – R3,000 | Recommended for inverter units |
Electrical installation must comply with regulations from the Department of Mineral Resources and Energy and Eskom guidelines. Only certified electricians should perform this work.
Example calculation: For a 12000 BTU installation with 8 metres total pipe run (5m extra), additional piping cost = 5 × R350 = R1,750. Plus electrical R2,500 = R4,250 extra beyond the base installation. Always ask your Cape Town aircon installer for a detailed breakdown.
📍 Installation Cost by City (2025)
Prices vary significantly across South Africa due to labour rates, demand, and regional requirements. Here’s what you can expect to pay for standard installation (labour only) in major centres.
Johannesburg
Average installation labour: R1,800 – R4,500 per unit
Joburg experiences extreme summer heat (often 32°C+), driving high demand for aircon installation. The competitive market keeps prices reasonable, but availability can be tight during peak season (October–February).

⚠️ Hidden Installation Costs to Watch For
Many homeowners discover additional costs only after work has begun. Here are the most common hidden charges and how to avoid them.
Copper piping extra
Most quotes include 3m only. Each additional metre costs R250-450. For long runs, this can add R2,000-5,000.
Electrical upgrades
Isolator, breaker, and dedicated circuit often excluded. Budget R1,500-4,000 for full electrical work.
Wall drilling
Concrete or reinforced walls may need core drilling – add R500-1,500 per hole.
Concrete cutting
For floor-standing units or through concrete slabs – R1,000-3,000 extra.
Roof brackets
If outdoor unit goes on tiled or corrugated roof – R800-2,000 for custom brackets.
Scaffolding
Second-storey installations – R3,000-8,000 if not included.
Gas refill
If existing system is moved, gas may need topping up – R800-2,000.
Removal & disposal
Removing old unit – R500-1,500 depending on access.
These extras can add R2,000 – R8,000 to your total installation cost. Always ask for a comprehensive quote that includes all potential charges.
How to avoid hidden costs: Insist on a site inspection before quoting. Reputable free inspection services mean the installer sees your actual installation conditions and can quote accurately. Never accept a quote based on photos alone – they always miss something.
💡 Inverter vs Non-Inverter Installation Cost Difference
Inverter air conditioners are increasingly popular in South Africa due to loadshedding and electricity costs. But how does installation differ?
| Item | Non-Inverter | Inverter | Difference |
|---|---|---|---|
| Unit price (12000 BTU) | R5,500 – R8,500 | R7,500 – R12,000 | +R2,000-3,500 |
| Installation labour | R1,800 – R3,500 | R1,800 – R3,500 | Same |
| Electrical requirements | Standard | May need surge protection | +R1,500-3,000 if added |
| Total installed | R7,500 – R12,000 | R10,500 – R16,000 | +R3,000-4,000 |
Key point: Installation labour is identical. The cost difference comes from:
- Higher purchase price of inverter units
- Potential need for surge protection (recommended for sensitive electronics)
- More complex PCB boards that require careful handling
However, inverter units save 30-50% on electricity costs and run better during loadshedding due to soft-start technology. Read our detailed inverter vs non-inverter comparison for payback calculations.
Important for inverter installations: Ensure your installer has experience with inverter units. They require proper vacuuming and correct refrigerant charging – mistakes can damage the expensive compressor PCB. Always verify installer certification through SAQA registered qualifications.

❓ Frequently Asked Questions
How much does AC installation cost in South Africa?
Average installation labour costs range from R1,800 – R4,000 per unit. Total installed cost (unit + labour) ranges from R6,500 for a small 9000 BTU unit to R30,000+ for large 24000 BTU systems. For a full 3-bedroom home, budget R40,000 – R65,000. Get free quotes from local installers for accurate pricing in your area.
How long does aircon installation take?
Typically 3–5 hours for a standard single unit installation. Back-to-back installations can be done in 2-3 hours, while complex extended runs or double-storey installations may take 5-8 hours. Multiple units are usually installed over 1-3 days depending on access and complexity.
Is installation included in the aircon price?
Usually no. Aircon prices quoted by retailers are for the unit only. Installation is sold separately by the retailer’s installers or third-party contractors. Always confirm whether quoted prices include installation – many online deals exclude it, leading to surprise costs.
Is professional installation required?
Yes, absolutely required for three critical reasons: 1) Warranty validity – most manufacturers void warranties if installed by unqualified persons, 2) Safety – refrigerant handling and electrical work require certification under SANS 10147, and 3) Performance – improper installation reduces efficiency and lifespan. Learn how to choose a qualified installer.
What size aircon do I need for a bedroom?
For standard bedrooms: 12-18m² needs 9000 BTU, 18-25m² needs 12000 BTU. Use our BTU calculator for exact sizing based on ceiling height, sun exposure, and insulation. Local free inspections can confirm requirements.
Do I need an electrical certificate for aircon installation?
Yes – any new fixed wiring requires an Electrical Certificate of Compliance (COC) under South African law. Your installer should provide this for the electrical work performed. This is your legal protection and required for insurance purposes.
Can I install an aircon myself to save money?
Not recommended and potentially illegal. Refrigerant handling requires certified technicians under F-Gas regulations. Electrical work must comply with regulations. DIY installation voids warranties, risks damaging expensive equipment, and can be dangerous. Professional installation costs R1,500-4,000 – worth it for safety and warranty protection.
How much does copper piping cost for aircon?
Additional copper piping beyond the included 3 metres costs R250 – R450 per metre (pair of insulated pipes). For a 10-metre total run (7m extra), budget R1,750 – R3,150 extra. Always confirm included pipe length in your quote.
What’s the difference between back-to-back and extended installation?
Back-to-back means indoor and outdoor units on the same wall – cheapest at R1,500-2,500 labour. Extended installation means units are separated (around corners, different walls) costing R3,000-7,500 labour plus extra piping. Your site inspection determines which is possible.
Do aircon installers charge for quotes?
Most reputable local aircon installers offer free quotes, especially for standard installations. ServiceLink SA’s free inspection service connects you with certified installers who provide no-obligation quotes. Always confirm before booking.
❌ Common Mistakes When Installing Aircons
After 21+ years in the construction and digital industry, our team has seen thousands of aircon installations. Here are the most common mistakes homeowners make – and how to avoid them.
Wrong size unit
Oversized units short-cycle, waste electricity, and don’t dehumidify properly. Undersized units run constantly and wear out faster. Always calculate correctly.
Cheapest quote only
The lowest quote often excludes essential items (piping, electrics, isolators). Compare like-for-like specifications, not just price.
Poor outdoor unit placement
Units placed in direct afternoon sun, blocked by plants, or without adequate airflow struggle to cool and consume more electricity.
Skipping vacuum pump
Some installers skip proper evacuation. Moisture in the system destroys the compressor within months. Always confirm they use a vacuum pump.
No electrical certificate
Electrical work without a COC is illegal and invalidates insurance. Insist on certification.
Ignoring maintenance
Filters clogged, coils dirty, drains blocked – all reduce efficiency. Follow our maintenance checklist.
Expert insight from ServiceLink SA Technical Team: “We’ve seen installations fail because homeowners didn’t verify installer credentials. Always check for SAQA-registered refrigeration qualifications and ask for proof of insurance. A small extra effort upfront saves thousands later.”
