Supply and installation of energy-efficient inverter split air conditioners for homes, offices and shops, correctly sized for the room and installed neatly with the pipes and drain properly finished.
Quick answer: As a rough guide: 9,000 BTU for a room up to about 15 m², 12,000 BTU for about 15–25 m², 18,000 BTU for about 25–35 m², and 24,000 BTU for about 35–50 m². Go one size up for rooms with high ceilings, lots of glass, west-facing windows or an open-plan layout.
Back-to-back installations from R1,650. That's when the indoor and outdoor units sit on opposite sides of the same wall. Longer pipe runs and extras are quoted upfront (see what affects the price).
Free aircon service 6 months after installation. Every aircon we install gets a free service six months later: filters, coil, drain line and a performance check, so it keeps cooling the way it did on day one.
Correct sizing is the most important part of an installation. An undersized aircon runs flat out and never cools the room properly. An oversized one switches on and off too often, which wastes power and leaves the room clammy. We work out the right size on site based on the room, ceiling height, windows and sun exposure.
For most Gauteng homes we recommend inverter units. They adjust their speed instead of switching on and off, so they use noticeably less electricity, run more quietly and keep a steadier temperature. Most inverter units can also heat the room efficiently in winter.
Use this table as a starting point. We confirm the right size during the site visit:
| Room size | Recommended size | Typical rooms |
|---|---|---|
| Up to about 15 m² | 9,000 BTU | Small bedroom, study, home office |
| About 15–25 m² | 12,000 BTU | Main bedroom, small lounge, office |
| About 25–35 m² | 18,000 BTU | Lounge, large bedroom with en-suite, small open-plan area |
| About 35–50 m² | 24,000 BTU | Open-plan living area, boardroom, small shop |
| Over 50 m² | Two units or a larger/commercial system | Large open-plan homes, offices, restaurants |
If the installation needs a new dedicated electrical circuit, it must be done by a registered electrician and certified with an electrical Certificate of Compliance (CoC). We'll tell you during the site visit if your installation needs this.
Quick answer: An inverter aircon costs a bit more to buy but uses less electricity, is quieter and holds a steadier temperature. A non-inverter (fixed-speed) unit is cheaper upfront but costs more to run if you use it often.
If you'll use the aircon regularly in summer or for heating in winter, an inverter unit usually pays back the difference through lower electricity bills. Most new units also use R32 refrigerant, which is more efficient and has a lower environmental impact than the older R410a.
Many estates and sectional title complexes in areas like Dainfern, Kyalami, Midstream, Waterfall and Silver Lakes have rules about where outdoor units can go and how they must look. Check with your HOA or body corporate before the installation. Some require approval, a specific position (often out of view from the street), or a cover for the outdoor unit.
Tell us about any estate rules when you book, and we'll plan the unit positions and pipe run to match them.
Quick answer: Installation is quoted per job. The price depends on the unit size and brand, the distance between the indoor and outdoor units, the wall type and access height, and whether a new electrical circuit is needed. Send us photos of the room and the outside wall on WhatsApp for a quick estimate.
Costs go up with longer pipe runs, installations high up on double-storey walls, concrete walls that need extra drilling, extra trunking for a neat finish, and condensate pumps where water can't drain by gravity. For typical price ranges, see our appliance repair cost guide.
If your aircon is over 10 to 12 years old, uses the old R22 gas, or needs a new compressor, replacing it with a modern inverter unit is usually better value than repairing it. The running cost savings add up quickly if you use it often. We can remove your old unit as part of the installation.
Hours: Monday to Saturday, 07:30 to 17:30. Most call-outs are handled the same day, subject to technician availability. For estates, send your access details when you book and we'll arrange gate entry.

This Samsung outdoor unit sat on a flat rooftop in Kempton Park, exposed to full sun, rain and wind all year. When we opened it up, the rust had gone right through the casing corners, the top and side panels, and the internal support frame around the electrical box. At that point, patching the rust isn't worth it: the panels, frame and brackets keep failing, and the coil and electrics are next. We replaced it with a new outdoor unit that has a blue anti-corrosion treated coil, which stands up far better to an exposed rooftop. Tip: for rooftops, pool areas and other exposed spots, choose an outdoor unit with a blue coated coil and coated or galvanised brackets, and have it serviced every year. Read our guide to rusted aircon outdoor units.
Not every aircon goes on a house. In Randfontein we installed an Alaska inverter split aircon on a trailer unit built from insulated panels. A trailer brings its own challenges: the panels are thinner than a brick wall, the whole unit gets towed and vibrates on the road, and everything has to stay within the trailer's height. We mounted the outdoor unit on sturdy brackets fixed through the panel frame on the end wall, fitted the indoor unit inside, and ran the pipework, drain and cable neatly down the outside. We secured everything for travel, vacuumed the system and tested it cooling. Tip: on trailers, mobile kitchens, site offices and containers, ask your installer how the units are fixed to the frame, not just to the panel. Road vibration loosens weak mounts over time.
This customer works from a home office in Essexwold, and the room was getting too hot to work in comfortably. We installed a Unitherm split aircon high on the wall, between the window and the cornice, where it blows across the whole room without pointing straight at the desk. Because it's a working office full of paperwork and electronics, we kept the mess to a minimum. While one technician drilled the hole through the wall for the pipes, the other held a vacuum right at the drill bit to catch the dust before it could spread. We then fitted the mounting plate and indoor unit, ran the pipes, drain and cable outside to the outdoor unit, vacuumed the system, released the gas and tested it. The office was cool and ready to work in the same day. Tip: in a home office, mount the aircon so the airflow doesn't blow directly onto your chair or desk. Across the room, or above a window, is usually most comfortable.
We installed a ceiling cassette aircon in a commercial building in Kempton Park that was being fitted out. A cassette unit sits in or under the ceiling and blows air out in four directions, so it cools a large open-plan space more evenly than a wall unit, and it keeps the walls free for shelving, screens and displays. We hung the cassette on threaded rods anchored into the concrete slab, levelled it so the condensate drains properly, and ran the insulated copper pipes and drain neatly across the ceiling to the outdoor unit. We worked alongside the other contractors on site: electricians were busy with the lighting while we did the aircon. Tip for businesses: if you're renovating or fitting out a space, bring the aircon installer in early, before the ceilings and lighting are finished. Pipe routes, drains and power are much easier and neater to plan at that stage.
We installed two IQ split aircons in this Rivonia double-storey home. With no space for the outdoor units at ground level, both went high on the walls on sturdy brackets, one between the upstairs and downstairs windows and the other near the gutter line on the first floor. Working at height takes the right ladders and a careful setup, and the brackets have to be anchored properly into the wall to carry the weight of the unit and its vibration for years. We ran the pipes, drains and cabling neatly, vacuumed both systems, released the gas and tested each aircon. Tip: mounting an outdoor unit high on a wall keeps it out of the way and safe from knocks, but make sure it can still be reached for servicing. Tell your installer if you'd prefer a spot that's easier to get to.
With summer on the way, this Hyde Park customer wanted the home cooled before the real heat arrived. We installed three split aircons: two Goldair units and one Samsung. The outdoor units went on galvanised wall brackets along the side of the house, lifted off the ground, with space around each for airflow. Two of them sit side by side under a window, and the third is around the corner near the patio. We ran the copper pipes and cabling neatly along the wall, connected the condensate drains to the existing downpipes so water doesn't pool on the paving, vacuumed each system, released the gas and tested all three units. Tip: if you're installing more than one aircon, plan where the outdoor units go first. Grouping them on a shaded side wall, with enough space between them, keeps the house looking tidy and helps every unit run efficiently.
We installed a new Unitherm split aircon in this Kempton Park entertainment room. The indoor unit was mounted high on the wall so it cools the whole room evenly, with the pipe work run neatly in trunking. The outdoor unit went on wall brackets outside, off the ground and with space around it for airflow. After connecting, we vacuumed the system, released the gas and tested it cooling. Tip: keep the outdoor unit clear of plants and clutter. It needs free airflow to get rid of heat, and a blocked unit cools poorly and costs more to run.
We installed a new Unitherm split aircon in this Pretoria West home. The indoor unit was mounted high on the wall and levelled so the condensate drains properly, and the outdoor unit was set up outside with the copper pipes, drain and cabling run neatly between the two. Once connected, the system was vacuumed, the gas released, and the aircon tested on cooling and heating. Tip: a level indoor unit matters. If it tilts the wrong way, water can drip from the front instead of running out of the drain pipe.
A new Logik split aircon installation in Centurion. We mounted the outdoor unit on wall brackets beside the window and ran the pipework and cabling down the wall in neat white trunking, so the installation looks tidy from outside. The system was pressure-tested and vacuumed before the gas was released, then tested on cooling. Like every aircon we install, it gets a free service six months later.
A back-to-back installation in Midrand: the indoor unit is mounted on the inside of the same wall as the outdoor unit, so the pipes go straight through the wall. It's the quickest and most affordable type of installation, and our back-to-back installations start from R1,650. We mounted the Unitherm outdoor unit on wall brackets below the balcony, ran the drain pipe and cabling neatly down the wall, and tested the system before handing over.
The client wanted two rooms cooled: one with a brand-new Samsung inverter split, and one with a second-hand Samsung unit they already owned. Before reinstalling the used unit, we checked it for damage, corrosion and leaks and made sure the indoor and outdoor units were a matched pair. We mounted both outdoor units on wall brackets, one above the other, ran the cabling and pipework in neat trunking, and pressure-tested and vacuumed each system before releasing the gas. Both aircons were tested and cooling properly before we left. Tip: a second-hand aircon is usually worth reinstalling, as long as it's checked first and installed as carefully as a new one.
Yes. We check it first for damage, corrosion and leaks, make sure the indoor and outdoor units are a matched pair, then install it the same way as a new unit: pressure-tested, vacuumed and tested before we leave. We recently installed a second-hand Samsung inverter alongside a brand-new one in Midrand.
Installation is quoted per job, based on the unit size and brand, the pipe length between the indoor and outdoor units, the wall type and access height, and whether a new electrical circuit is needed. Send us photos on WhatsApp for a quick estimate.
A 9,000 BTU unit suits most bedrooms up to about 15 m². A main bedroom of 15 to 25 m² usually needs a 12,000 BTU unit. Go one size up if the room gets a lot of afternoon sun or has a high ceiling.
A standard single split unit installation is usually completed in one day. Multiple units, long pipe runs or commercial systems take longer.
For most homes, yes. Inverter units use less electricity, are quieter and keep a steadier temperature. If you use the aircon regularly, the lower running cost usually makes up for the higher purchase price.
Yes. Most modern inverter split units have a heat mode and heat a room efficiently, often using less power than a standard electric heater.
Often, yes. Many estates and complexes have rules about where outdoor units can go and how they must look. Check with your HOA or body corporate before the installation.
