The range
What is in the Rinnai range?
Rinnai is a Japanese company best known in Australia for gas heaters and hot water systems. Its Australian range also includes reverse cycle split systems and ducted air conditioning, and ducted gas heating that can be paired with cooling. Rinnai is not on our current list of supplied brands, so this page is a guide, not a dealer listing.
On the Gold Coast, winters are mild enough that most homes heat with reverse cycle air conditioning rather than gas, so the cooling side of a system usually matters most. A reverse cycle system heats and cools from the same unit using electricity.
If you are choosing a new reverse cycle system, we can quote a comparable split or ducted system from a brand we supply, such as Daikin, Fujitsu or Panasonic.
Systems
Which Rinnai system suits your home?
Rinnai suits households that already have Rinnai gas appliances and want one brand, and buyers in cooler areas where gas heating is common. On the Gold Coast and in the Tweed, a reverse cycle system from any major brand usually covers both summer cooling and winter heating.
Supply
Can Frost Solutions supply Rinnai?
Rinnai is not on our current list of supplied brands. Call us and we will tell you straight whether we can quote it for your job. If not, we will recommend a comparable system from a brand we supply and explain the differences, so you can decide with the full picture.
The brands we currently supply and install are Daikin, Mitsubishi Heavy Industries, Samsung, Hisense, Fujitsu, Mitsubishi Electric and Panasonic.
Warranty
What warranty comes with a Rinnai system?
Rinnai sets its own manufacturer’s warranty, and the terms differ by product and by whether the unit is in a home or a business. We confirm the manufacturer’s terms for the exact model in your written quote. Every system we install also carries our own warranty, listed below.
- 10-year workmanship guarantee. Covers the gas (refrigerant) charge and call-outs.
- 10-year duct and pipework warranty. On the ductwork and pipework we install.
- 5-year parts and labour on units. Indoor and outdoor units. Hisense units carry 5+2 years.
- 5-year zonetouch controller warranty. On the ZoneTouch zone controller.
Warranties apply once the job is paid in full. Full details on our warranty page.
Before you buy
What should you check before choosing Rinnai?
Check four things before you settle on any brand: how you use each room, where the outdoor unit can go, how exposed the house is to salt air, and whether your switchboard can take the load. Our free on-site inspection covers all four, so the quote you get is the job we do.
- Supply. Rinnai is not on our current supplied-brand list, so ask us first whether we can quote it or a comparable system.
- Gas or electric. Reverse cycle heating avoids a separate gas heating system in most Gold Coast homes.
- Solar. If you have or plan rooftop solar, running reverse cycle air conditioning during the day can make good use of it; see solar and batteries.
- Gas work. We are air conditioning and electrical contractors; gas appliance work is outside this guide.

Good questions
Rinnai questions
Do you install Rinnai air conditioning?
Rinnai is not on our current list of supplied brands. Call 1300 101 100 and we will tell you whether we can quote it, or recommend a comparable reverse cycle system from a brand we supply. See all air conditioning brands.
Do I need gas heating on the Gold Coast?
Most Gold Coast homes heat with reverse cycle air conditioning, which heats and cools from one system. Gas heating is more common in colder climates. See ducted air conditioning for whole-home reverse cycle.
Can you replace an old Rinnai split system?
Yes, we remove the old unit and install a new reverse cycle system, checking whether pipework and wiring can be reused. See air conditioning replacements.
What warranty comes with Rinnai?
Rinnai sets its own manufacturer warranty, which varies by product. Any system we install also carries our 10-year workmanship guarantee once paid in full. See our warranty.

From my initial phone call to the pre-check and installation, all correspondence and actions were clear and understandable (for someone who is non tech savvy).. Shout out to Paul (Senior Technician) ... He was also clear when showing me how to use the air-con, and info on future servicing and cleaning when needed. Thanks Frost Solutions Team, I highly recommend you to anyone needing a new aircon :)

Wow! Frost Solutions is possibly the best all round company I've worked with for a long time. The admin staff, sales and tradesmen-installers were all very polite, efficient and easy to communicate with. From the time I phoned to organise a quote to the full install was only an about a week ...

Incredible service from start to finish! ... We had some extenuating circumstances that caused a number of delays at our end, and a significantly sloping site, but the crew from Frost were super accommodating, kept in touch but we're never pushy to get "the sale". ... We would highly recommend Frost.

Thank you Frost Solutions. Liam and Henry arrived before the booked time, a very good first impression. Both lads did a very professional job installing our Air con. The wife and I most definitely recommend the superb service of Frost Solutions.
