Quotes and booking

Getting a quote and booking

Is the quote free?

Yes. We give free, no-obligation on-site quotes. We look at your home, talk through how you use it and send you a written quote. Book a free quote.

How long is a quote valid?

21 days (3 weeks). After that the price may be revised to current pricing and availability. Ducted quotes are subject to a final site inspection, and any change in scope found at that inspection is agreed with you before we go ahead.

What happens after I accept a ducted quote?

We contact you to book the site inspection and installation date. Before the install we ask for the next payment so we can order your unit. The balance is due on completion of the installation.

What happens after I accept a split system quote?

We order the unit and organise an exact date and time. On the day our technicians walk through the house with you to agree where each unit goes, then install and commission the system and clean up before they leave.

How much is the deposit and how can I pay?

For ducted systems we take an upfront payment of up to 50%, which covers the deposit, quoting and planning time and ordering your unit and materials. Final payment is due on completion. We accept card or bank transfer. Your quote shows the exact stages. See our terms and conditions.

Can I pay off a new system?

Finance options are available for new systems. See our finance page for current details, or ask us when we quote.

What if I need to cancel or move my install?

Tell us as early as you can. We would much rather rebook your job for another time. If a job is cancelled completely with less than 48 hours’ notice, 50% of the deposit may be forfeited, although we can waive this.

Choosing a system

Choosing the right system

How do I know which type of air conditioning I need?

It mostly comes down to how many rooms you want to cool and how the house is built. A split system suits one room. A multi-head system runs several rooms from one outdoor unit. Ducted air conditioning covers the whole home through ceiling outlets. We recommend one at the free quote.

Which brands do you install?

We supply and install Mitsubishi Heavy Industries, Daikin, Samsung, Hisense, Fujitsu, Mitsubishi Electric and Panasonic, with ZoneTouch or AirTouch 5 controls on ducted systems.

What is the difference between ZoneSwitch and AirTouch 5?

Both run your zones. A ZoneSwitch (ZoneTouch) wall controller turns each zone on or off at one set temperature. AirTouch 5 has a sensor in each room, so each zone holds its own temperature, and you can control it from a touch screen, phone or tablet over Wi-Fi.

Can I have ducted air conditioning with a tight roof space?

Often, yes. Some ducted indoor units are slimmer than others, and Mitsubishi Heavy Industries makes splittable indoor units that can go into tight roof spaces. We check the roof space at the free quote and choose a unit and layout that fits.

Can you put ducted air conditioning in a home with raked ceilings?

Usually. Where there is no roof space above a raked ceiling, air can often be supplied from a neighbouring roof space through a wall (side) grille instead of a ceiling outlet. Every house is different, so we confirm the options on site.

Can I keep my existing ductwork when I replace a ducted system?

Sometimes. We assess the ductwork when we quote and replace only what needs replacing. Old, damaged or poorly insulated ducting is usually worth replacing at the same time. See ductwork replacement and repairs and air conditioning replacements.

What is R1.5 insulated ducting?

Ducting with more insulation than standard R1.0 ducting. It loses less heat along the way, so rooms reach temperature faster, there are fewer hot and cold spots and the system does not work as hard. We offer it as an upgrade on ducted systems.

I live near the beach. Do I need rust protection?

It is worth considering. Salt air corrodes outdoor units. Our optional treatment takes the outdoor unit apart and applies three coats of HVAC Action rust protection to the panels and circuit board before installation. See corrosion protection.

Can a ducted system help with air quality?

Yes. We can fit a Fresh-Aire UV APCO-X Ultra in the return air. Its UV-C lamps shine on the cooling coil and the air passing it, and a carbon matrix reduces household odours. The lamps are replaced about every 3 years. See air filters and sanitisers.

Running and servicing

Running, cleaning and fixing your system

What is the best temperature to run my air conditioner?

For efficient cooling we recommend turning the system on in the morning, setting it to 22°C and leaving it to run all day, rather than starting it in the heat of the afternoon. Cooling only the zones you are using saves more.

How often should I have my air conditioner cleaned?

We recommend having your air conditioning system cleaned every 6 months. Washable filters can be rinsed in between. Regular servicing is also part of keeping your warranty in order. See air conditioning maintenance.

Why is my air conditioner leaking water?

The usual causes are a blocked condensate drain, a dirty filter or coil, or a drain without enough fall. Turn the system off, catch the drips and call us. See leak repairs.

Why isn’t my air conditioner working properly?

Check the mode, the remote batteries, the circuit breaker and the filters first. If it still is not cooling or heating, call 1300 101 100 and we will check it. See air conditioning repairs and common air conditioning problems.

Warranty and licences

Warranty, licences and our team

What warranty do I get with a new installation?

A 10-year workmanship guarantee covering the gas (refrigerant) charge and call-outs, a 10-year warranty on duct and pipework, 5 years parts and labour on units (Hisense 5+2 years) and 5 years on the ZoneTouch controller. Warranties apply once the job is paid in full. Warranty details.

Can not servicing my system affect the warranty?

Yes. You need to have the system maintained and serviced as we recommend. Not doing so may void the warranty. We can do the servicing for you.

Are you licensed?

Yes. QBCC 15409367, ARCtick AU064493 for refrigerant handling and Queensland electrical 1505904. NSW electrical work is done by our NSW-licensed electrician.

Do you use subcontractors?

No. An in-house licensed team: 3 office staff and 9 field technicians, with our own electricians and no subcontractors. Meet the team.

Do you do electrical work?

Yes. Our own licensed electricians handle the electrical side of your installation and other electrical work. We test everything and give you an electrical safety certificate. See electrical services.

Your property

Your property, approvals and the install

Who arranges body corporate approval?

The owner or customer arranges any body corporate approval before the install. Council, building or body corporate approvals are not included in our quotes.

What if my house has asbestos?

Accepting a quote confirms that, as far as you know, the property does not contain asbestos. If asbestos is found during the install, work stops in that area. Testing sheeting and cutting any penetrations through it is organised and paid for by the customer.

Will I need patching or painting after a split system is replaced?

Sometimes. A new unit may be a different size from the old one, leaving marks or holes on the wall. Plastering and painting are not included unless your quote says so.

Are switchboard upgrades included?

Only if they are on your quote. Switchboard upgrades or changes to the main power supply are quoted separately when needed. We check your switchboard during the free on-site quote.

    I have just had a total of 5 aircons fitted up by the boys at Frost. 4x brand new installs to each bedroom, and a new replacement for the lounge. I cannot fault anything. Their communication, punctuality, price and workmanship have all been superb throughout the entire process. Trouble and stress free. Its easy to see why they have so many 5star reviews. True professionals. Thanks again.

    Absolutely fantastic experience with Frost Solutions! I recently had a ducted air-conditioning system installed and honestly, from the very first conversation through to the finished installation, the whole process was seamless. ... The installation itself was done to a really high standard, the team worked efficiently and left everything clean and tidy. ... Great people, great communication, great workmanship and a great result.

    Couldn't recommend Frost Solutions highly enough. We recently had them install a 16kW Daikin ducted system with 8 outlets, 6 independent zones, AirTouch 5, multiple upgrades and a 5 year service plan. ... Another big positive is that Frost Solutions have their own electrical team as part of the installation. ... the entire experience was seamless.

  • ★★★★★

    Frost Solutions installed ducted air conditioning in my home today and I couldn't be happier. The team were professional, friendly, punctual, and down to earth. ... left the house spotless ... I also really appreciated the follow-up call from the office later in the day to check I was completely satisfied ... They're a local business with local staff, and the value was extremely competitive for the quality of service and workmanship provided.

  • ★★★★★

    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 :)

    Sue Google review, about Jun 2026

  • ★★★★★

    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 ...
