What Centrotech (pty) Ltd does
Centrotech (Pty) Ltd is a Johannesburg-based air conditioning and HVAC services contractor founded in 1983 by Managing Director Keith Forrester. The company specializes in cooling requirements for server rooms and data centres, which constitute approximately 80% of its workload, with the balance covering general commercial air conditioning, VRV installations, chilled water piping, chiller installations, and thermal insulation. It serves government institutions, South African universities, banking institutions, and corporate clients across the Gauteng region, with named project evidence including chilled water circuit installation for the South African Police Service (SAPS) and a dry cooler installation for BMW.
The company's underlying technology is mechanical HVAC rather than software or digital, spanning chilled water systems, VRV (Variable Refrigerant Volume) systems, precision cooling for server and UPS rooms, and thermal insulation of chilled water piping. Centrotech is an accredited service provider for eight major equipment manufacturers: Airedale, Carrier, Samsung, Climaveneta, Emerson, Bluebox, Stultz, and Daikin. It holds BEE Level 3 and cidb 4ME certifications, which are required or strongly preferred for South African public sector and construction procurement.
The business model combines one-time project-based HVAC installation revenue with recurring maintenance revenue under tailored Service Level Agreements (SLAs). SLAs specify equipment, maintenance frequency, planned service summaries, and maintenance history tracking, and include a 24/7 callout commitment with a stated two-hour average response time. Go-to-market is direct and sales-led, relying on long-standing relationships, referrals, and demonstrated service expertise rather than marketing or channel partners. The firm remains privately held and founder-led, with no evidence of external investment, M&A activity, or expansion beyond the Johannesburg/Gauteng market.
