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.

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.

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 use our cooling calculator.

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 3-5 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.

Heating and Air Conditioning equipment should be serviced at least once a year. The best scenario is to have the heating system checked in the Fall and the air conditioning checked in the Spring. Oil-fired equipment should definitely be cleaned and serviced annually.

Annual servicing includes cleaning the system, checking for any problems or potential problems and adjusting for Peak efficiency. The benefits include:

We get asked this question all the time. And having the HVAC system properly sized is extremely important.

A system that is too large will cool or heat your house quickly, but you may not feel comfortable. That's because it will satisfy the thermostat before it can adequately remove sufficient moisture from the air during the cooling mode, leaving you feeling sticky and humid. This could even lead to moisture and mold problems. And, the stress of short-cycling (too many starts and stops) will shorten the life of your equipment and increase your heating and cooling bills.

On the other hand, a system that is too small just cannot get the job done, especially in extreme weather conditions. The air conditioner will run constantly in the summer and the furnace will do the same in winter.

But a correctly sized system isn't just based on the size of the structure. Many factors go into determining the size of the system. Including type of house and walls, type and size of windows, insulation, basement and attic conditions, house orientation, and so on. A Salesman must visit the house and take detailed measurements and notes while conducting the survey.
