Answers to All Your Inquiries

What size HVAC system should I have?

Contrary to popular belief there, is no rule of thumb for sizing a system to a home. Depending upon the construction of your home, a medium size room (20–40m2) such as a Bedroom with ensuite or a small lounge requires between 2.5kW and 5kW. The only way to insure the size of the system you purchase will be large enough to cool your home, but not any larger than you need, is to have your home’s individual heating and cooling needs evaluated by a licensed professional.

How can I increase the efficiency and life of my home’s heating and cooling systems?

The most important thing you can do is clean and replace your filters frequently. Also, a system heats and cools more evenly when the blower is in the “on” position. The blower provides constant air movement throughout the home, and allows for better filtration. Finally, shades, drapes, shutters, or screens should be installed on windows that are exposed to extreme sunlight.

Should I get a Reverse Cycle or Evaporative System with Ducted Gas Heating System?

Even with the benefits of evaporative systems, homeowners now want to switch to reverse cycle air conditioners. The function of this type of AC is different compared to regular air conditioners. Reverse cycle is based on the concept of conventional electric heaters and coolers.

However, it does not have to create energy as conventional heaters do. Rather, it absorbs heat that comes from the air outdoors. Then, it will warm the air inside, making this machine incredibly energy-efficient. It is perfect for those who contend with the climate.

This type of air conditioning unit has a reversible refrigeration cycle, which means that it produces heat rather than cooling. You can think of it as two systems in one unit. These two systems work harmoniously together to give you a more comfortable living environment.

In cooling mode, this AC type works like the air conditioner you are used to. However, if you turn on reverse cycle for heating, it performs the following:

• The evaporator coil will switch its role to reverse the cycle. In this case, it will become the condenser coil, which will then allow the unit to produce heat.

• Meanwhile, the condenser unit, which is located outdoors, will switch its role as well. As a result, it will become the AC’s evaporator, causing it to discharge cold air instead. The air will be much colder compared to the air outside.

• A reverse cycle air conditioner is a great appliance to have whether in summer or winter.
