Question 1

How much does aircon installation cost in Sandton in 2026?

Accepted Answer

In Sandton, a 9,000–12,000 BTU midwall split unit costs approximately R8,700–R11,800 fully installed (unit + back-to-back installation). An 18,000–24,000 BTU unit runs R14,600–R21,600. Long pipe runs, trunking, core drilling, or extra electrical work add to the cost.

Question 2

How much does it cost to service and re-gas an aircon in Sandton?

Accepted Answer

A service plus re-gas for a standard split unit in Sandton typically costs R1,200–R1,700. A clean/service only (no gas) is around R600–R950. If a unit keeps losing gas, there's a leak that must be repaired — repeated re-gassing alone is not a fix.

Question 3

Do aircon technicians in Sandton need to be registered?

Accepted Answer

Yes. Anyone handling refrigerant gas — installing, re-gassing, or decommissioning an air-conditioner — must by law be SAQCC Gas registered and carry a valid card. All aircon technicians on FlowLeads in Sandton are pre-verified for SAQCC Gas registration and public liability insurance before acceptance.

Question 4

How often should I service my air conditioner in Sandton?

Accepted Answer

At least once a year, ideally before summer. Regular servicing — cleaning filters and coils, checking gas pressure and drainage — keeps your unit efficient, lowers your electricity bill, and prevents expensive compressor failures. Homes in dusty areas or with heavy use may need servicing twice a year.

Question 5

Why is my air conditioner not cooling?

Accepted Answer

Common causes are low refrigerant (a leak needing repair + re-gas), clogged filters or coils restricting airflow, a failing capacitor or compressor, or a blocked drain. A registered technician will diagnose the actual fault before quoting, rather than simply re-gassing a unit that keeps losing gas.

Question 6

What size aircon do I need for a room in Sandton?

Accepted Answer

As a rough guide: 9,000 BTU suits a small bedroom/office (up to ~18 m²), 12,000 BTU a standard lounge/bedroom (up to ~25 m²), 18,000 BTU a large open-plan room (up to ~40 m²), and 24,000 BTU+ very large spaces. Sun exposure, ceiling height, and insulation also matter — a technician confirms the correct size on site.
