Energy-Efficient Heating and Cooling Systems

That really depends on your space, lifestyle, and energy goals. But some of our most popular and reliable options include Rinnai systems for all-round performance, Emerald for larger properties and double stories, and Mitsubishi Electric for quiet comfort. We also offer trusted brands like Panasonic, Midea, and Daikin and HiSense. Our team can help you find the perfect fit based on your home and budget.

Energy-efficient systems, like Rinnai heating and cooling and Emerald heating and cooling, use inverter technology that adjusts based on demand, reducing electricity consumption and lowering long-term energy costs.

Yes — that’s exactly what these systems are built for. Whether you’re facing scorching summer heat or freezing winter mornings, modern units like Rinnai heat pumps, Emerald, and Mitsubishi Electric systems are designed to perform in a wide range of Aussie conditions.

In really cold weather, you might notice your system going into something called a defrost cycle, especially if you’re using a reverse cycle air conditioner. This is totally normal. It’s just the system clearing ice buildup from the outdoor unit to keep things running smoothly.

You might hear a bit of hissing or rattling, or notice it cycling on and off — nothing to worry about. Just make sure the fan setting is on “auto” so it doesn’t blow cold air indoors during the cycle. When it’s all clear the system will start heating again.

Rinnai heating and cooling systems are our #1 seller among Carbon Savers customers and for good reason. As a trusted Japanese brand, they deliver premium quality at a more affordable price point, giving you excellent bang for your buck.

They’re known for being super energy-efficient, offering reliable temperature control with dual functionality, and using environmentally friendly refrigerants. The compact design integrates easily into any home, and with Wi-Fi connectivity, you can control your comfort from anywhere.

They strike that perfect balance between performance and sustainability, making them a solid choice for homeowners who want comfort they can count on (without the big power bills).

Emerald heating and cooling systems are a great choice if you’re looking for smart, energy-efficient climate control without the premium price tag. As a trusted Australian brand, they offer great rebates and exceptional value that’s hard to beat.

They’re especially perfect for double-story or larger homes – in fact, they’re the only systems that provide equal airflow upstairs and downstairs, ensuring consistent comfort throughout larger spaces.

With quiet technology and flexible installation options, they work brilliantly in both residential and commercial settings. Emerald systems are particularly popular with homeowners who want affordability without sacrificing reliability, energy efficiency that reduces long-term costs, and a peaceful living environment – all from a brand that understands Australian conditions.

Honestly, these systems are built tough, so if something’s off, you’ll usually notice. That said, a quick spring cleaning once a year (like clearing vents and wiping filters) goes a long way in keeping things running smoothly.

Think of it like your car – sure, it’ll probably still get you from A to B even if you skip a few services, but you’ll get the best performance, efficiency, and lifespan when you look after it properly. Your heating and cooling system is the same. If you stay on top of the basics, your system won’t demand much, but booking a professional service every couple of years will keep everything in tip-top shape, prevent long-term buildup, and help you avoid those unexpected breakdowns that always seem to happen on the hottest or coldest day of the year.
