Aer-Mart is a leading Air Conditioning company based in Johannesburg, South Africa. As an authorised supplier of Samsung / Alliance / LG and Midea Air Conditioners Aer-Mart Air Conditioning offers a wide range of the best quality air conditioners.

Room size is dependent on the square meterage of the space. You can determine the size of your unit by multiplying the length x width of the room, then multiply this figure by roughly 600 Btu’s per m2. Each size unit on the website specifies the square meterage of the space it caters for.

E.g. A room size of 20m2 (5m across by 4 meters wide) will require a 12000btu size aircon. A room size of 40m2 (10m across by 4m wide) will require a 24000btu size aircon and so on.

The cost of the back-to-back aircon installation (i.e. indoor unit located on the other side of the wall opposite the outdoor unit) with available plug point for the 9000btu and 12000btu is R2500.00 (incl. VAT). The cost of the installation for the 18000btu and 24000btu is R2700.00 (incl. VAT)

The cost of this installation includes the following:

  • Up to 3metres of refrigerant piping, drain pipe and cable
  • Outdoor mounting bracket (if required)
  • Installation to a maximum height of 3metres above ground level
  • Drilling of one hole for piping
  • Holes will be filled but not painted

The installer will quote for all costs in addition to the 3metre back-to-back installation which will include but are not limited to the following:

  • Any required piping and cabling in addition to the piping and cabling referred to above, or electrical connection to the main switchboard
  • Travelling expenses in the event of the installation being out of a 30km radius from where the unit was bought
  • Any other extras, including but not limited to:
    • external isolators and additional electrical work required
    • any additional refrigerant piping, insulation, drain pipe and cable
    • trunking to cover piping

Please note costs of isolators are not included in the installation fee. Isolator switches are a regulation requirement and are not included in the cost of the installation. A qualified electrician must install an isolator at your own cost. He must install the isolator not more than 2metres from the condenser and within view of the condenser. The cost of this is in addition to the installation cost of the unit and must be paid directly to the electrician. Indoor and outdoor units must always be earthed.
