Using Split System Air Conditioners in Winter

How Your Reverse-Cycle Aircon Keeps You Warm.

In Brisbane, air conditioning is generally associated with staying cool during our hot summers. The temperatures are too high for the ceiling fan to deal with, so in steps the split-system aircon to pump cold air into your home or office. 

Switch seasons to winter, and what many people forget is your reverse cycle aircon is also designed to keep you warm when there’s a chill in the air. Its technology allows you to choose between blowing out cold air or hot air. This makes a split system the perfect companion for year-round comfort. 

What’s more, it’s an energy-efficient and affordable way to stay warm if you do it right. 

How Reverse-Cycle Split Systems Work

In winter, your split system aircon works in the reverse way to in the summer. Here’s a rundown of each mode: 

Cooling Mode

When your aircon is in cooling mode, it draws in warm air through its internal unit. This air passes over a coil filled with chilled refrigerant in the outdoor unit. The refrigerant pulls the heat and moisture out of the air and sends it back into your living space as cooler, drier air. 

Heating Mode

The process flips around when you turn it to heating mode. The refrigerant in the outdoor unit is compressed, which raises its temperature. The system pulls warmth from the outside air, even in cold weather, and pumps it inside. The air blows across the refrigerant and picks up it’s heat before being pumped indoors. You get a nice, toasty living space to enjoy! 

The Benefits of Using Split System Air Conditioners in Winter

So why use your air con for heating? A few good reasons:

1. Energy Efficiency

Reverse-cycle split systems are among the most energy-efficient heating options available. For every unit of electricity they use, they can produce three to five units of heat. That’s a solid return, especially when you’re watching the power bill.

2. Consistent, Controllable Warmth

You’re in control of the warmth. The system works to maintain whatever temperature you feel is comfortable. There’s no overheating or excessive drying out of the air. 

3. Cleaner Air

Your split system aircon unit has internal filters that clean the air. Your warm air won’t have dust or allergens floating in it. Don’t forget, though that the filters require regular maintenance. 

4. Quiet Operations

No rattling fans or loud humming sounds will provide the soundtrack to your winter days. Split-system aircon units are very quiet which makes them ideal for workspaces or bedrooms. 

Tips for Getting the Most Out of Your Split System Air Conditioners in Winter

Heating and cooling your home is one of the most energy-intensive parts of modern life. There are a few tips you can follow to reduce the pressure on your electricity bills! 

• A sweet spot for your thermostat is between 18°C and 20°C. This is optimum for energy efficiency and comfort.
• Use timers and programs. Preheat your home before you wake up or get home from work, then let it rest.
• Close off rooms you’re not using and remember to turn off the split system when you’re done with a space. You don’t want to heat unoccupied areas.
• Shut curtains and blinds at night to keep warmth from escaping through the windows.
• Keep the filters clean. Dirty filters make your unit work harder, which reduces airflow and costs more.
  

Don’t Do This In Winter…

If your winter heating bill has jumped or your split system isn’t doing its job, one of these might be the culprit:

• Cranking the temperature up to 25°C+. This forces the system to work overtime and won’t actually heat the room faster. Be patient—steady and moderate is better.
• Leaving doors and windows open. Even just a little draft can make your system work harder to maintain temperature. Shut it all tight.
• Ignoring your filters. Clogged filters reduce airflow and can even damage your system. Give them a clean every few weeks during peak use.
• Not using the ‘HEAT’ mode properly. Make sure your system is set to heating mode—not AUTO or FAN. Heating mode gives you direct control over the temperature output.
