Alair Air Conditioning supplies, installs, repairs and services air conditioners across Midrand. Our work ranges from estate homes in Kyalami and Carlswald to townhouses in Noordwyk and office parks in Waterfall and Samrand. Whether you’re building, renovating, replacing an old unit or keeping an existing system in good shape, we handle the full job.
Midrand is one of Gauteng’s fastest-growing areas, with new housing developments, glass-fronted office buildings and commercial parks going up constantly. Modern buildings like these trap a lot of heat, especially with large windows facing north or west. The right air conditioning system keeps them comfortable year-round, cooling on hot summer afternoons and heating on cold Highveld mornings.
Aircon Installation in Midrand
Existing homes and townhouses
Before we recommend anything, we assess the room size, window area, sun direction and insulation. That way the unit we install has the right capacity for the space.
- Midwall split units: efficient, quiet cooling and heating for bedrooms, living areas and home offices
- Ducted hideaway systems: concealed cooling for multiple rooms, popular in larger estate homes
- Window wall units: for smaller rooms where a split system isn’t practical
Midrand’s estates and sectional title complexes usually have rules about outdoor unit placement and visible pipework. We plan installations to comply with those rules and can supply the details your HOA or body corporate needs for approval.
New builds and renovations
The best time to plan air conditioning is before the walls are plastered and the ceilings go in. When we’re involved early, we can:
- Pre-pipe during construction, running copper piping, drainage and electrical supply inside walls and ceilings
- Plan ducted systems into the roof space and ceiling design from the start
- Position outdoor units so they’re hidden, well ventilated and easy to service
- Size the system from the building plans, before the space is finished
This avoids surface-mounted trunking, patching walls later and awkward compromises on unit placement. We work alongside homeowners, builders, architects and developers to fit air conditioning into the build schedule. Once construction is complete, we return to install the units and commission the system.
Offices and commercial buildings
- Cassette units: for offices and meeting rooms with ceiling boards
- Underceiling units: for open-plan offices, retail and restaurants
- Floor standing units: for boardrooms, training rooms and large spaces
- HVAC package systems: for larger commercial buildings
Aircon Repairs in Midrand
Our technicians repair all major air conditioner brands in Midrand, whoever installed the system. Contact us if your unit:
- Isn’t cooling or heating properly
- Is leaking water inside
- Is displaying an error code
- Won’t start, or keeps cutting out
- Is noisier than usual
- Has frozen pipes or coils
- Gives off an unpleasant smell
We diagnose the problem before quoting, so you know what’s wrong and what the repair involves. Common causes include refrigerant leaks, blocked drains, capacitor or fan motor failure, and control board faults. If the unit is old and a repair doesn’t make financial sense, we’ll quote on an energy-efficient replacement instead.
Aircon Servicing in Midrand
Construction dust from ongoing development, along with pollen and everyday debris, builds up quickly in aircon filters and coils. A dirty unit uses more electricity, cools less effectively and is more likely to break down.
Each Alair service includes:
- Cleaning or replacing filters
- Cleaning the indoor coil and outdoor condenser
- Clearing the drain line and drip tray
- Checking refrigerant pressures
- Inspecting electrical components
- Testing performance in cooling and heating modes
Service frequency:
- Homes: once a year, before summer
- Offices and retail: every six months
- Server rooms, restaurants and high-use systems: every three months
Maintenance contracts are available for office parks, property managers, estates and businesses running multiple units.
