We sell air conditioning units for use in domestic premises, offices, shops, food processing areas, factories, computer rooms and restaurants.

Air conditioning systems work by moving heat from inside your premises to the outside. In a central air conditioning system air is drawn into the ductwork system through the return air system. Installed in the return air ductwork is an evaporator coil. This coil is connected to the condensor, the unit that is outside your home, by copper tubing.

The refrigerant is then pumped from the condenser to the evaporator coil. As the refrigerant passes through the inside of the evaporator coil, warm air from inside your home passes over the outside of the coil. Because the refrigerant is cooler than the warm air, the refrigerant absorbs heat from the air. The refrigerant is then sent outside to the condenser unit. When the warmed refrigerant is in the condenser unit it is compressed by the compressor; the compression of the refrigerant causes it to boil. As the refrigerant boils it gives off the heat it picked up from inside your home. The refrigerant is then passed through the coil in the condenser unit where it gets cooled again and is ready to go back inside to pick up more heat from your home.

As this whole process is going on, the temperature and relative humidity in your premises are both lowered. The relative humidity level drops because cooler air cannot hold as much moisture. As the air cools, it gives up some moisture and it gets collected in the base of the evaporator coil and is then drained away. See here .

The purchase price of Air-conditioning units are now more affordable to the general public - a single system can now be purchased for as little as R2400.00 incl VAT for a profitable system. Get the prices here

In most circumstances, a single or twin split application can be installed in one day, with minimum disruption.

The benefits of Air Conditioning are to give a comfortable environment at work or at home throughout the seasons, Spring, Summer, Autumn and Winter. An Air Conditioning unit can have two functions - heating and cooling. With an auto changeover switch on most new units, you set the temperature and the unit will cool or heat as required automatically.

An anti-fungus filter is used - this catches allergy-causing mites, smoke particles and odours, making the air in your environment clean and fresh.

A quick and easy rule of thumb to use for sizing an air conditioner for a room or house is the square foot method. This formula is used only for a quick approximate and is based on certain guidelines regarding insulation R values, shading, ceiling height, construction materials, windows, doors, purpose of use and occupancy. In layman's terms, 400 square feet of residential living space in a desert climate requires 1 ton of cooling capacity based on adequate insulation, 8' ceiling height and tight windows and doors. To calculate your requirement using this method divide your total square footage of living space by 400. The resulting answer is the number in tons of air conditioning capacity required.

Air conditioning is a matured technology so most of the popular brands work well. Many of them use parts made by the same manufacturers. So, the main considerations are the price, warranty, attractiveness, noise, etc. Some manufacturers offer a 3 year warranty on all parts while others offer only 1 year. Some units are unattractive and will not compliment your landscaping. Whatever you decide, the most important consideration is the contractor you use. You may buy the best system in the world but if it is not properly installed, you will actually be buying nothing but a big headache for years to come. For your protection, make sure you use a specialised contractor.But then again, if you buy on of the ' cheapie's ', you might find that in 2 years time, you can't get spares, not even a replacement remote control. So it might be safer to stick to known brand names.

Yearly preventative maintenance is a wise thing to do. Properly maintaining your system will save you money on your energy bills and will help your system perform at peak efficiency. A properly maintained system also lasts longer which is important due to the expense of replacement. During a preventive maintenance, certain parts that can cause trouble when dirty, are cleaned to keep the system running smoothly and efficiently. A maintenance service also includes inspection of your system so problems can be discovered before serious damage occurs and you find yourself without air conditioning in the middle of summer or winter when you need it the most.
