June 10, 2025Canberra winters are no joke. With frosty mornings, sub-zero nights, and icy winds, heating your home efficiently is more important than ever. Whether you’re looking to cut down on energy bills or simply stay warm without blowing the budget, here are 7 practical heating tips to help you get through the season — including how to access interest-free finance through the ACT Sustainable Household Scheme.
1. Choose the right heating system for your home
Canberra homes vary greatly in size and structure, and so do their heating needs. A ducted system is a great solution for larger homes or families looking to heat multiple rooms evenly and at once. It’s discreet, efficient, and ideal for those who want full-home comfort with a single system.
On the other hand, a reverse cycle split system is perfect for smaller spaces, apartments, or rooms where targeted heating is more practical. It’s also a more cost-effective option for zoned or supplemental heating.
At Delta, we install both ducted systems and split systems, helping Canberra households choose the right system for their home layout, budget, and long-term energy efficiency.
2. Make use of the ACT Sustainable Household Scheme
Upgrading your old heating system doesn’t have to be a financial burden. Through the ACT Sustainable Household Scheme, eligible Canberra homeowners can access 0% interest loans to purchase and install energy-efficient heating systems.
Delta Air Conditioning & Heating is a registered supplier under the ACT Government’s Sustainable Household Scheme, which is administered by Brighte Finance. Through this initiative, eligible Canberra homeowners can access 0% interest loans of up to $15,000 to upgrade to energy-efficient heating and cooling systems. There are no upfront costs, and repayments are made over time with zero interest—making it easier for households to invest in cleaner, smarter solutions without financial strain.
That means you can install a brand-new ducted or split system with no upfront payment and interest-free repayments. It’s a fantastic opportunity to improve your home’s efficiency, reduce running costs, and contribute to a more sustainable Canberra.
Delta is proud to support customers through this process — we’ll help you choose the right system and provide everything you need to take advantage of the scheme.
3. Don’t underestimate insulation and sealing
Even the most efficient air conditioning system will struggle to heat your home if the warmth is escaping through cracks, gaps, or uninsulated areas. Canberra’s cold, dry winters make it especially important to seal up your home properly.
Simple changes can make a big difference:
- Add weather strips to doors and windows.
- Use draft stoppers under internal doors.
- Insulate your ceiling or top up older insulation batts.
- Close off unused rooms to keep heat where it’s needed.
Combining good insulation with an efficient heating system means less energy use, quicker warmth, and lower energy bills.
4. Set your thermostat efficiently
Did you know that every degree above 20°C can increase your energy usage by up to 10%?
To balance comfort and energy savings, aim to keep your thermostat between 18–20°C. It’s a small adjustment that can make a big difference over the course of winter.
With modern systems like Daikin or Mitsubishi reverse cycle air conditioners, you can enjoy precise temperature control, timer functions, and Wi-Fi connectivity-allowing you to adjust your heating from anywhere, even when you’re not home.

5. Use Zoned Heating When You Can
If you’re using a ducted system, zoning is one of the smartest ways to cut energy use and improve comfort. Instead of heating the entire house, you can direct warmth to specific areas – like the living room in the evening or bedrooms at night.
This helps reduce wasted energy and makes your system work more efficiently. Delta offers systems with advanced zoning control that can be tailored to your daily routine, helping you keep energy costs down while staying comfortable.
6. Service Your System Before Winter Hits
Your heating system works hard during winter, and like any appliance, it needs regular servicing to perform at its best.
Dusty filters, worn parts, or outdated components can:
- Reduce heating performance
- Drive up power usage
- Increase the risk of breakdowns when you need it most
Before the cold weather kicks in, book a professional service with Delta. We offer comprehensive servicing for all major brands to ensure your system is running cleanly, quietly, and efficiently through the colder months.

7. Upgrade to an Energy-Efficient System
If your current system is more than 10 years old, it could be using far more energy than necessary and struggling to keep your home consistently warm. Upgrading to a modern, energy-efficient system is one of the best ways to reduce your heating costs and improve overall comfort.
At Delta, we supply and install a range of advanced systems from trusted brands like Daikin, Mitsubishi, LG, Hisense and more; that are known for their reliability and performance in Canberra’s extreme climate.
Daikin systems are engineered for Australian conditions and offer:
- Energy-efficient inverter technology that reduces running costs
- Whisper-quiet operation, perfect for bedrooms and living areas
- Smart features including Wi-Fi control and air purification filters
We also install Mitsubishi models equipped with:
- Plasma Quad Plus filters for cleaner air (removes allergens, dust, and bacteria)
- Precise temperature control and zoning compatibility
- Durable performance even in sub-zero Canberra mornings
Whether you need a ducted solution for whole-home comfort or a split system for targeted heating, we’ll help you find the right system to suit your home and budget — and show you how to apply for a 0% interest loan through the ACT Sustainable Household Scheme.
