Q: How often should I service my air conditioner?

A: For residential homes, we recommend a full service once a year. For commercial properties (offices, restaurants, shops), a service every 3 to 6 months is ideal to maintain performance and air quality under heavy use.

Q: What are the signs my aircon needs a repair or service?

A: Look out for these common warning signs:

  • Poor Cooling: The unit is on, but the air isn’t cold.

  • Weak Airflow: The fan is running, but very little air is coming out.

  • Bad Smells: A musty or mouldy smell indicates a need for a deep clean.

  • Strange Noises: Grinding, squealing, or banging sounds are not normal.

  • Water Leaks: Dripping water from the indoor or outdoor unit.

  • High Electricity Bill: A sudden spike in your bill can mean your unit is working too hard.

Q: Why is my air conditioner leaking water?

A: The most common reason is a clogged drain pipe. Dust, algae, and dirt can build up and cause a blockage, forcing the condensation to overflow back into your room. Our service includes a full flush and cleaning of the drain line to fix and prevent this.

Q: What is the difference between an Inverter and a Non-Inverter aircon?

A: An Inverter aircon is more modern and energy-efficient. It varies its compressor speed, using only the exact amount of power needed to hold the temperature. A Non-Inverter (fixed speed) unit’s compressor turns on at 100% power and then switches off completely, which uses more electricity. Inverters are quieter, more efficient, and save you money in the long run.

Q: How long should my air conditioner last?

A: A well-maintained air conditioner can last anywhere from 10 to 15 years. Regular annual servicing is the single best way to ensure your unit reaches its maximum lifespan.

Q: Do you service all brands?

A: Yes. Our technicians are trained and equipped to service and repair all major air conditioner brands, including Samsung, LG, Daikin, Alliance, Midea, York, Carrier, Jet-Air, Trane, and many more.

Q: How much does a standard aircon service cost in Johannesburg?

A: A standard service for a residential split-unit air conditioner in Johannesburg typically costs between R700 and R2,500. This service includes a full clean of the indoor and outdoor units, cleaning filters, checking gas levels, clearing drain pipes, and testing the unit’s performance.

Q: What is the average price for aircon installation in Johannesburg?

A: A standard “back-to-back” installation (where the indoor and outdoor units are on the same wall) has a typical price range:

  • 9,000 to 18,000 BTU Units: R1,800 – R3,000 excluding the unit cost.

  • 24,000+ BTU Units: R2,200 – R3,500 This cost is for labour and basic materials (e.g., 3-4 meters of piping). More complex installations requiring extra piping, trunking, or work at heights will cost more. Excluding the unit cost.

Q: How much does it cost to re-gas an aircon?

A: If your aircon is not cooling and needs a re-gas, the cost in Johannesburg is usually between R800 and R1,500. This price can depend on the type of refrigerant and the amount needed. Important: A simple re-gas is a temporary fix. Our technicians will always perform a leak test first to find and repair the source of the leak.

Q: How much does a new air conditioner unit cost? (Unit Only)

A: The price depends on the size (BTU) and the type (Inverter or Non-Inverter). Inverters are more expensive to buy but save you significant money on electricity.

Here are typical unit-only price ranges:

Aircon Size Non-Inverter (Unit Price) Inverter (Unit Price)
9,000 BTU R6,000 – R7,500 R7,500 – R11,000
12,000 BTU R6,500 – R8,000 R8,000 – R12,500
18,000 BTU R9,000 – R11,500 R11,000 – R15,000
24,000 BTU R12,000 – R15,000 R15,000 – R20,000+
Q: What is the total cost for a new aircon and installation?

A: You can get a good estimate by adding the unit price and the installation cost. For example, a standard 12,000 BTU non-inverter unit (R7,000) with a back-to-back installation (R2,000) would cost around R9,000. A 12,000 BTU Inverter model fully installed would likely start from R10,000 to R14,500, depending on the brand.

Q: Is an Inverter aircon worth the extra price in South Africa?

A: Absolutely. An inverter aircon can be 30% to 50% more energy-efficient than a non-inverter. With high electricity costs, an inverter unit often pays for the price difference in savings within 1-2 years. They are also much quieter and perform better during power fluctuations (loadshedding).
