So you’re planning on heating and cooling installation Melbourne, and you’ve settled on choosing a ducted HVAC for your home.

If you ask us, you’ve made the right call! Ducted HVAC is the most powerful choice, with the widest coverage area and the most powerful heating and cooling.

Of course, it’s also the most expansive and complex of your options too.

And as the most complicated type of heating and cooling installation, there are a whole range of different considerations and factors that go into ducted HVAC installation.

What sorts of things are we talking about?

What is important when designing a heating and cooling system?

Choosing the right size and system

You’d think that a more powerful system would be the simple choice, right?

However, that’s not the case – in fact, an oversized system can actually cause more problems than it solves!

That’s because air conditioning systems accumulate the most wear-and-tear upon starting up and powering down. All the time in between is surprisingly gentle on your system.

A large system reaches its target temperature sooner, and shuts down. Then the temperature naturally rises throughout the day and it boots up again to restore your comfort, before shutting off again.

Rinse and repeat until your system is worn-out and in need of ducted reverse cycle air conditioning service and repairs.

A larger system powers up and down more frequently, which wears it out faster. The best way to avoid this (besides regular servicing) is to choose one that’s perfectly sized for your home.

Energy efficiency

Everybody’s worried about their quarterly electricity bill. And air conditioners are energy-hungry appliances – that’s why it’s so important that you choose one that’s as energy efficient as possible.

Luckily, today’s systems have kept up with the increasingly loud cries for energy efficiency, with technology like VRV/VRF filtering their way down from commercial systems into residential ducted systems.

And with that comes reductions of over 50% on your air conditioning-related expenses!

Turning your ducted heating and cooling system on doesn’t mean that the entire house needs to be cooled.

With gates built into your ductwork, our team can create zones and give you the power to only cool the sections of your home that need it.

And unlike installing multiple split systems, this particular method allows you to control your comfort from a single central thermostat.

If you’ve decided on zoning, it’s important that you choose a system that can scale up or down depending on how many zones you have and how large they are. And that’s something that our experienced team can help you out with!

All your (other) HVAC questions, answered

Can you install your own HVAC system?


HVAC systems are big and complex, and often involve electrical work and cutting open parts of your ceiling to install ductwork.

Not only that, but refrigerants have the potential to burn, meaning it can only be handled by someone with a proper license.

What is the average life of a HVAC system?

The average lifespan of a HVAC system is around 15 years, give or take

Of course, this assumes constant use – if you’re gentler on your system or use alternatives when the temperature isn’t too unbearable, your system can last much longer.

And if you keep up with your system’s maintenance needs, you can stretch this out even further!

What is the most efficient heating and cooling system, and how can I make my heating and cooling more efficient?

As we mentioned above, VRV/VRF technology is one of the best ways to make your home heating and cooling more energy-efficient.

However, they aren’t the only ones.

You can also reduce your energy usage with a number of other low-tech techniques, such as by hanging a wet towel in front of an open window, using fans or using your air conditioning strategically (such as letting nature take over when the evening starts cooling down).

What’s the most reliable HVAC system?

If you ask us, there’s no such thing as a “most reliable” system or brand, since your system’s lifespan and reliability will also depend on how you use it and how frequently you get your system maintained.

We do rely on a network of brands, and we choose them for their durability, efficiency, technology, and ongoing support system.

That’s why we here at Alpha Air work exclusively with Daikin ducted heating and cooling and 

Mitsubishi reverse cycle ducted air conditioning.

These are large brands that have proven records of reliability – whichever one you choose, you’re getting a system you can trust!

I have an existing HVAC system – how much of that can be integrated into my new system?

It’s hard to answer this question, as in many cases it will depend on the specifics.

That having been said, as a general rule, we will often be able to reuse much of your existing infrastructure, including in many cases your existing ducts themselves.

Whenever possible, our team will endeavour to incorporate existing ducts and vents into your new system, bringing down the amount of work that needs to be done and reducing how much you’ll need to pay.

How long will installation take?

A lot of people assume that installing ducted reverse cycle air conditioning in Melbourne can take days, and even weeks.

Not so with Alpha!

This in-depth process ensures that we have a course of action and all the right equipment for the big day, and allows us to complete the job in a single day!
