EFFICIENT CLIMATE CONTROL

What are reverse cycle ducted systems?

Reverse cycle ducted systems offer efficient climate control for your entire home by heating and cooling through a network of ducts. These systems consist of an indoor unit, which distributes air via ducts, and an outdoor unit that manages heat exchange, providing year-round comfort.

The ducted design means conditioned air is evenly distributed through ceiling or floor vents, maintaining a consistent temperature throughout every room in your home.

DUCTED VS SPLIT SYSTEMS

Ducted vs split system: which is right for your Perth home?

A ducted system is the best choice when you want discreet, whole-home climate control with even temperatures in every room. If you only need to heat or cool one or two spaces, a split system is often the more cost-effective option.

Not sure which way to go? We'll assess your home's size, layout, and how you use each room, then give you honest advice — not the most expensive option. Plenty of Perth homes end up using a combination of both.

DUCTED AIR CONDITIONING COST

How much does ducted air conditioning cost in Perth?

There's no one-size-fits-all price — the cost of a ducted reverse cycle system depends on a few things:

  • The size of your home and how many rooms need conditioning
  • The number of zones you want to control independently
  • The brand and energy efficiency of the unit (we install trusted brands like Daikin and Panasonic)
  • The complexity of the ductwork and any electrical or switchboard upgrades required

Because every home is different, we give you a free, no-obligation quote with clear, upfront, fixed pricing and no surprises. Flexible finance options are available to spread the cost into easy instalments.

WHAT TO EXPECT

Our ducted air conditioning installation process

It starts with a free in-home assessment, where we measure your space, talk through your zoning needs, and recommend the right system. Once you're happy with the quote, we book the installation at a time that suits you.

Our licensed team fits the indoor unit, runs the ductwork, installs the ceiling vents, and connects the outdoor unit — typically over one to three days with minimal disruption. We test every zone before we leave and back the work with a workmanship guarantee, then keep it running with annual servicing and repairs.

Frequently Asked Questions

Otter Air has developed a reputation amongst our clients as being honest, reliable, efficient and provide a professional service that delivers what we promise.

How much does ducted air conditioning cost in Perth?

Most Perth ducted installs land in the $12,000-$15,000 band. Smaller homes can start around $8,000; larger executive homes can push past $22,000. The biggest variables are home size, number of zones, and whether the switchboard needs upgrading.

Do I need three-phase power for ducted?

Almost never. Residential ducted systems up to 18kW run fine on single-phase supply. In 10 years installing across Perth we've only needed three-phase once.

How long does a ducted installation take?

99% of ducted installs in existing Perth homes are completed in a single day. Two installers, one full day on site. Larger jobs or new-build installs can stretch over two days.

Can I control different zones independently?

Yes. Modern ducted systems use a wall controller with zone control, so you only cool the rooms you're using. Properly zoned, a ducted system often runs cheaper than two splits going at once.

Which brands do you install?

Panasonic is our top pick for most Perth homes - premium quality at a sharper price, and the only brand offering nanoeX air purification in its ducted range. Daikin and Mitsubishi Electric are also premium; Midea is the value option. We can source any major brand on request.

What size system do I need for my home?

A rough rule for Perth's climate: 140-160W per square metre of conditioned space. A 200m² home typically needs 14-16kW. We do a proper load calculation at every free quote considering insulation, window orientation, and room usage.

A real Perth job

Ducted replacement after a mid-summer breakdown

This customer's old Mitsubishi ducted system cut out in the middle of summer. We replaced it with a new Panasonic ducted system and added an Advantage Air MyPlace IQ controller, wiring it into the home's existing control system so it runs alongside their other air conditioner from a single interface. Back up and running — and quieter — before the next heatwave.
