Most homes in hot climates have air conditioners. For some, air conditioning Canberra is a luxury. But for many, it’s a necessity. Given the cost of the equipment and the energy needed to run it, we want homeowners and businesses to learn about their ACs. These ten points should make you aware of your cooling system: Its functions, use and maintenance. In case you want to replace the unit, look for a competent HVAC expert.

How it works

Basically, air conditioners extract heat from the surrounding air and then blow that cold air into your home. This is made possible by the evaporator coil and refrigerant charge.

Ton of cooling

The term “ton” is not new in the air conditioning world. Its basic definition is delivering 12000 BTU. Small ACs are about 2 tons and large ones about 5 tons.

Common AC problems

Air conditioners are complex mechanical systems. They depend on multiple conditions to work properly. If there is extreme heat indoors or a reduction in airflow or the refrigerant leaks, the unit may not be able to function efficiently. If not fixed quickly, such problems could leave you with no cooling or expensive repair bills.

Filters’ role

Every air conditioning unit has a filter which cleans the AC and removes particles from the air. As the filter performs its job, it collects more and more particles. Consequently, airflow reduces and resistance increases. When this happens, it’s time to replace the filters.

Maintain the system

Routine maintenance like changing filters can be done professionally or as a DIY project. It’s good to remove debris and dirt from the coils at the beginning of each cooling season. Airflow and refrigerant problems require expert servicing.

Ducts matter

Duct leakage may lead to low production of cool air. Leaks often sap the energy out of an air conditioner. It’s even worse if the duct is positioned in garages, crawlspaces and attics. Exterior ducts should be well insulated. Insulation can be done by a professional contractor or a keen homeowner.

Increase energy efficiency

One of the best ways to improve efficiency is sealing leaky ducts. It also helps to clean evaporator coils, replace dirty filters, clear debris and maintain the right airflow. If you are replacing the AC, consider buying high-efficiency equipment. Higher efficiencies are quite cost-effective.

Lighten your load

To boost the performance of your air conditioner, reduce the amount of work it has to do. Simply improve your building by reducing air leakage, shading windows or increasing insulation levels. However, that may require substantial investment and time. Reducing internal load is simpler and cheaper. Just shut off unneeded lights, equipment and electrical appliances.


An ideal AC should clean, cool, heat, ventilate, moisten and dehumidify. Ventilation is important. Without it, contaminants accumulate indoors leading to significant comfort and health problems. Experts recommend that there be sufficient ventilation to freshen the indoor air every four hours.

Heat and Humidity

In hot, humid climates, lack of humidity control can lead to mould growth and other moisture-related issues. Modern air conditioners cool and dehumidify. This is part of controlling temperature and reducing moisture.
