Can Home AC Installation Increase Property Value?

Picture this: It’s a sweltering 34-degree summer afternoon on the Mornington Peninsula. The sea breeze is doing its best, but your house still feels like a toaster oven. Then you step into a neighbour’s place where crisp, cool air greets you like the lobby of a luxury hotel. What’s the difference? They’ve invested in home AC installation.

Now, here’s the kicker — when it comes time to sell, that neighbour’s property might not only feel more comfortable — it could also fetch a better price on the market. But is AC truly a value-adding upgrade, or just another expensive home improvement that makes you feel good but doesn’t pay off? Let’s unpack this in detail.

Why Comfort Is a Selling Point

Think about your own buying habits. If you’re touring homes in summer, you’re not just looking at the layout — you’re noticing how the space makes you feel. A house that’s hot, sticky, and stuffy feels like a burden. One that’s cool and breezy feels like home.

Comfort is emotional, and in real estate, emotion drives decisions. In Mornington Peninsula, where summers can be humid and winters get brisk, buyers want the assurance that their new home is liveable year-round. AC provides that reassurance.

It’s a bit like heated seats in a luxury car — you might survive without them, but once you experience the upgrade, it’s very hard to go back. Buyers know this too, which is why AC is increasingly seen not as a “nice-to-have” but a must-have.

The Numbers: Does AC Add Real Value?

Experts in property valuation suggest that air conditioning can increase resale value by 5–10%, depending on the type of system and the neighbourhood. On a $900,000 Mornington Peninsula home, that’s anywhere between $45,000 and $90,000 in added value.

But not all AC systems are created equal. Buyers place different value on different setups:

Type of System	Buyer Appeal	Impact on Property Value	Notes
Split-System AC	Moderate	Small boost in comfort/resale	Ideal for smaller homes or apartments
Ducted AC	High	Strong resale value increase	Preferred for larger family homes
Evaporative Cooling	Moderate	Moderate lifestyle benefit	Less effective in humid coastal air
Smart AC Systems	Very High	Adds tech appeal + value	Younger buyers love the “smart home” angle

This table shows one thing clearly: the type of installation matters. Ducted and smart systems are more likely to give you a noticeable bump in buyer interest (and property price) compared to single-unit splits.

Lifestyle Appeal in the Peninsula

Mornington Peninsula isn’t just about houses — it’s about lifestyle. Buyers here are often professionals moving from Melbourne, young families wanting coastal comfort, or retirees chasing relaxation. That means modern, comfortable, stylish homes are in high demand.

Air conditioning fits neatly into that picture. Just as a renovated kitchen or sleek bathroom creates a sense of luxury, a home with a reliable AC system feels “move-in ready.”

I’ve personally seen buyers walk away from beautiful homes because “it didn’t have cooling.” Why? Because for them, it wasn’t just a house — it was a lifestyle decision. And lifestyle, especially in coastal areas, is everything.

The Cost vs. Return Equation

Let’s not sugarcoat it: installing AC isn’t cheap. But when you break down the numbers, it often makes sense.

• Split system (single room): $1,200 – $3,500
• Ducted system (whole home): $8,000 – $15,000+
• Smart-enabled systems: Additional $500 – $1,000 upfront

So, is it worth it? Well, consider this: If your $900,000 property increases in value by just 5% thanks to AC, that’s $45,000 added. Even if you spent $12,000 on ducted installation, you’d still be ahead.

Plus, you’ll benefit while living in the home. Think lower stress, better sleep, and the joy of entertaining guests in comfort. In other words, AC isn’t just about the resale — it’s about enjoying your home now and cashing in later.

Energy Efficiency = Modern Buyer Magnet

Today’s buyers don’t just want cold air. They want cold air without the guilt trip of high energy bills. That’s where modern, energy-efficient systems make a real difference.

New AC units are designed to consume less power, and some come with zoning features that let you cool only the rooms you’re using. Smart systems even connect to your phone, so you can pre-cool your living room before you arrive home.

This isn’t just a convenience — it’s a selling point. In fact, government resources like Energy.gov.au highlight how high-efficiency appliances cut long-term costs, which is a huge drawcard for eco-conscious buyers.

My Take: The Intangible Value

Here’s what I’ve noticed: AC doesn’t just change the numbers on paper — it changes the way a home feels.

Step into a property with ducted AC and the vibe instantly shifts. It feels newer, sleeker, more premium. Buyers pick up on that. It tells them, this is a home where details matter.

In contrast, walk into a house without AC on a hot day, and suddenly all the other positives — fresh paint, polished floors, landscaped garden — fade into the background. Comfort (or the lack of it) steals the show.

The Emotional Edge in Negotiations

Let’s be blunt: real estate is emotional.

Imagine two homes for sale on the same street, both similar in price, size, and design. At the open home, one is cool, airy, and inviting. The other has guests fanning themselves with brochures.

Which one feels worth signing a contract for? Which one might spark a bidding war? Comfort tips the scales — and AC is the invisible feature that can make or break a negotiation.

Conclusion: Worth It?

So, does home AC installation increase property value? In Mornington Peninsula, the answer is a confident yes.

It adds comfort, improves liveability, makes your home feel more modern, appeals to eco-conscious buyers when energy-efficient, and — importantly — delivers a competitive edge in a market where lifestyle is everything.

Think of it not as an expense, but as a comfort upgrade today and a value boost tomorrow.
