Alair Air Conditioning is a full-service air conditioning company working across Johannesburg. Our clients include homeowners in the northern suburbs, corporate offices in Sandton and Rosebank, and restaurants, retailers and industrial premises throughout the city. We supply and install new systems, repair faulty units, and service existing air conditioners so they run reliably and efficiently.
Johannesburg’s hot summer afternoons and cold, dry winters mean an air conditioner gets used in both seasons. A properly sized inverter system handles both, keeping homes and workplaces comfortable while keeping electricity costs under control.
Aircon Installation in Johannesburg
Residential installations
For houses, townhouses and apartments, we typically install:
- Midwall split units for individual rooms
- Ducted hideaway systems for concealed whole-home cooling
- Window wall units where a split system isn’t practical
For estates and sectional title complexes, we plan outdoor unit placement and pipe routing to meet body corporate and HOA rules. We can also supply the specifications you need for approval.
Commercial installations
Offices, retail spaces and hospitality venues each have their own cooling demands, driven by occupancy, equipment heat, glass frontages and opening hours. We install:
- Cassette units for offices with suspended ceilings
- Underceiling units for open-plan spaces, shops and restaurants
- Floor standing units for halls, showrooms and large rooms
- HVAC package systems for larger commercial and industrial buildings
Before we recommend anything, we assess the space and calculate the cooling load, so you don’t overspend on capacity or end up with a system that can’t keep up.
Aircon Repairs in Johannesburg
We repair all major air conditioner brands across Johannesburg, from single split units in homes to high-capacity commercial systems.
Common faults we repair:
- Poor cooling or heating
- Temperature swings and inconsistent performance
- Water leaks and condensation problems
- Error codes, control board and electrical faults
- Compressor and fan motor failures
- Refrigerant leaks and regassing
- Noise and vibration
- Units that fail after power outages or storm surges
Our repair process:
- Assessment: we check the system and discuss the symptoms you’ve noticed.
- Diagnosis: we test the unit to find the actual cause, not just the symptom.
- Quotation: you get a clear, upfront price before any work starts.
- Repair: we fix the fault using quality replacement parts.
- Testing: we check performance and efficiency before sign-off.
If an older unit isn’t worth repairing, we’ll tell you honestly and quote on an energy-efficient replacement.
Aircon Servicing in Johannesburg
Dust, pollution and airborne debris build up in air conditioners, particularly in busy urban areas and near main roads. The result is higher energy consumption, weaker cooling, poorer air quality and a greater risk of breakdown.
Our aircon service includes:
- Filter cleaning or replacement
- Indoor coil and outdoor condenser cleaning
- Drain line and drip tray clearing
- Refrigerant pressure checks
- Electrical and component inspection
- A full performance test
Recommended service intervals:
- Homes: once a year
- Offices and retail: every six months
- Restaurants, server rooms and high-use systems: every three months
We offer planned maintenance contracts for offices, retail chains, property managers, schools and multi-site businesses across Johannesburg. Scheduled servicing means fewer emergency call-outs and more predictable costs.
