Keeping your home warm in winter and cool in summer

Posted September 25, 2015

Perth is a land of extremes. In the winter it’s not uncommon to get temperatures of below 5 degrees, while in the summer, we can often experience 40 degrees or even higher. These temperature extremes make it absolutely crucial that you can keep your home warm in the winter and cool in the summer, all without running your energy costs through the roof.

Most homes in Perth rely on reverse-cycle air conditioning units in order to fight the good fight between excessive heat and cold. These air con units are made to take warm air from the outside and make it cool in the summer and then do the reverse in the winter, making these units super-efficient when it comes to only having one primary heating and cooling system.

Many of these air con systems have fairly advanced features, though this depends on the design of your home and your climate control requirements. Central air units feature ducting through the interior walls of your home that terminate in vents, which will typically blow either hot or cold air out of an exit port on a wall or a ceiling. Meanwhile the system itself is usually fitted with sensors to monitor the temperature in different regions of the home; these sensors transmit data back to a wall-mounted controller that keeps the system working how you tell it to.

When it comes to either heating or cooling an entire house, efficiency is a crucial component to any system. Thankfully modern air con units are highly efficient; in fact, a minimum of three kilowatts of cooling or heating capacity are typically produced from just one kilowatt of electricity these units consume. Ducted systems are constructed to be thermally efficient, which makes sure that the air traveling from the unit to the room it’s destined for doesn’t cool down or heat up before it gets there. Meanwhile, split-system and window units are required to have clear energy efficiency star ratings on them, making it easy to if you’re in the market for one.

Of course there are other ways to ensure your system efficient. Draw the shades during hot days and cold nights helps to keep heat where it should be, either in or out. Keep your doors and windows closed while your system is running. Meanwhile, start your unit early to get a jump on the day.
