Refrigeration Service

The owner is liable for any cost incurred for the maintenance of the air conditioner, as the product warranty does not cover any of these costs.


Typically, air conditioning units are covered under warranty for 3 years to 10 years depending on the manufacturers. This means the manufacturer will pay to fix your AC if it stops working during that time. It is important that the units are serviced to remain under warranty and also perform as expected. The manufacturers will require proof of the bi-annual (once in six months) service reports if the air conditioning unit develops technical faults requiring replacement of parts under warranty. In high corrosive areas once every three (3) months cleaning cycle is required. A detailed warrantee specification is available upon request.

The warranty only remains in effect if you adhere to its terms and conditions.

Heating Services – Heat Pumps

Why Heat Pumps?

Heating geyser water is typically the largest cost of energy in home today. An average South African family will spend R5000 (as at December 2013) or more to heat water every year! The Geyser Heat pump is a heat pump that is designed specifically to heat your geyser water using hardly any energy. The Geyser Heat pump is connected to any existing electric, gas, oil, or propane water geyser in any home or business.

It makes use of a renewable energy source – the ambient air temperature in a garage, roof, basement or utility room is drawn in through the condenser to heat the water. The Geyser Heat pump is up to 370% efficient as compared to 60-95% for traditional water heating systems.

This means that for every 1 unit of energy required to operate The Geyser Heat pump, 3.7 units of energy are generated from the ambient air to heat the water. In laymen’s terms this means for every R1,00 you spend on electricity you get R3,70 worth by using renewable energy source.


Refrigeration Service

In certain cases up to 3 geysers can be heated with one heat pump. While Kwikot geysers are recommended, most geyser types can be used. Oil, gas, or propane usage is significantly reduced which means lower running costs, fewer emissions, smaller carbon footprint, and a safer and healthier environment for all.


  • Highly efficient (up to 370%)
  • Fail safe design ensures hot water at all times
  • Various models suitable for any size geyser
  • Engineered for safe and easy installation
  • Virtually maintenance free
