Aircon installation in Johannesburg: how it works

A good aircon installation starts long before the drill comes out. With 15 years of experience in the trade, our team follows the same proven process on every job, from a single bedroom unit to a full office fit-out:

  1. Site assessment: we measure the room, check sun exposure, ceiling height and how many people use the space, then recommend the right BTU size.
  2. Positioning: we agree on where the indoor and outdoor units go so the airflow is even, the noise stays away from bedrooms and the outdoor unit can breathe.
  3. Electrical supply: larger units get a dedicated circuit and isolator, installed by our own electrical team.
  4. Installation: wall brackets, insulated copper piping, a correctly sloped drain line and neat trunking that matches your walls.
  5. Vacuum and commissioning: the system is vacuumed to remove moisture, gas pressures are checked and the unit is tested on cooling and heating.
  6. Handover: we show you how to use the remote, clean the filters and get the best efficiency from your new aircon.

What affects the cost of an aircon installation?

Every site is different, which is why we quote after seeing photos or visiting. The main factors are:

  • The size and type of unit (standard split, inverter or multi-split)
  • The distance between the indoor and outdoor units, which determines the length of piping
  • Wall type and access, including high walls, rooftops or units that need ladders and scaffolding
  • Whether a new electrical circuit is required
  • The number of units installed at the same time

We always send a clear, itemised quote so you know exactly what you are paying for, with no surprises on the day.

Residential and commercial air-conditioning

For homes we install quiet, energy-efficient inverter units in bedrooms, lounges and home offices. For businesses we handle offices, boardrooms, shops, restaurants, clinics, schools and server rooms, where reliable cooling keeps staff productive and equipment safe. Commercial clients can add a maintenance plan so every unit is serviced on schedule.

Signs your aircon needs servicing or repair

  • The room takes much longer to cool down than it used to
  • Water is dripping from the indoor unit
  • A musty or burning smell when the unit switches on
  • Rattling, buzzing or grinding noises
  • Ice forming on the copper pipes
  • The unit trips the breaker or shows an error code
  • Your electricity bill has gone up for no clear reason

Catching these problems early usually means a smaller repair bill and a longer life for your aircon.

FAQ

Air-Conditioning Questions

How often should an aircon be serviced?

Residential aircons should be serviced at least once a year, and commercial units every 3–6 months depending on usage.

What size aircon do I need?

It depends on room size, sun exposure and occupancy. As a guide, a 12,000 BTU unit suits most bedrooms and small offices. We confirm the right size when we quote.

Is an inverter aircon worth it?

Yes. Inverter aircons adjust compressor speed instead of switching on and off, so they use significantly less electricity and run quieter.

Do you install aircons I buy myself?

Yes, we can install units you have already purchased, provided all parts are included.

How long does an aircon installation take?

A standard split aircon installation usually takes 3 to 5 hours. Multi-unit or commercial installations can take one or more days depending on the number of units and access.

Can an aircon also heat in winter?

Yes. Most modern split and inverter aircons have a heat-pump mode that warms the room efficiently in winter, often using less electricity than a heater.

Where should the outdoor unit be installed?

It should be on a solid wall or level surface with space around it for airflow, out of direct heavy rain where possible, and as close to the indoor unit as practical to keep piping short.

Do you service aircons in Zimbabwe?

Yes. We take on air-conditioning projects across Zimbabwe, including Harare and Bulawayo. Contact us with the site details for a quote.
