Imagine a scorching summer afternoon in Mornington Peninsula – the shores are stunning, but your commercial air conditioning is working overtime. You watch the bill climb and think, “There’s got to be a smarter way!” You’re not alone. Across Victoria, businesses find cooling costs can skyrocket, especially when HVAC (heating, ventilation and air conditioning) makes up nearly half of energy use.
But don’t sweat it – with a few savvy tweaks, those costs can plummet. In this guide I’ll walk you through everything from thermostat tricks and ceiling fans to government rebates, all in plain Aussie-English. Whether you’re managing an old unit or planning a commercial AC installation, by the end you’ll know exactly how to keep cool and keep cash in your pocket.
As any café chef juggling ovens and coolers will tell you, commercial kitchens run hot. Smart AC use in places like this boosts comfort without burning dollars.
1. Know Your Cooling Costs
First up, let’s get real about the numbers. In many workplaces, HVAC can gobble up around 50% of your energy bills. Yikes! That means for every dollar you spend on power, half might be just to keep things cool. The good news is that many of those dollars can be saved. One quick win: thermostat settings. Business Victoria recommends 24°C in summer (20°C in winter) for comfort and efficiency.
Believe it or not, each 1°C you raise the summer set-point can cut AC costs by about 10%. It’s like an invisible 10% off coupon – and honestly, a 1°C change is almost undetectable on your skin. Think of it this way: setting the thermostat at 25°C instead of 24°C for a day could slice 10% off that day’s cooling bill! (I’ve done the math and that adds up fast.)
Track and Audit Usage
To save smart, first track how much you’re using. Get a handle on your energy bills or install submeters for the AC circuits. Mornington businesses often find they blow cold air all night – or run every zone at once – without realising the cost.
Simple data from your utility bills can show if summer usage spikes are really peaking as you’d guess. Once you spot patterns, you can target fixes. Even better, consider an official energy audit. In Victoria, trained assessors (many recommended by the Energy Efficiency Council) can pinpoint where your biggest wastage is – and they often know local Mornington grants and rebates too.
Quick Checklist:
- Review last 12 months of energy bills to spot peak usage.
- Have someone (an “energy champion”) watch your energy data – it pays off.
- Ask your distributor for time-of-use and demand charges info (some businesses pay extra for peak loads).
2. Master Your Thermostat
This is the low-hanging fruit. You control temperature, you control costs. Aside from the 24°C summer tip, consider these strategies:
- Gradual Adjustment: Try bumping your setpoint up half a degree at a time. You’ll hardly notice going from 24°C to 25°C, but that tiny bump can shave a bundle off energy use.
- Night vs Day: If your AC supports scheduling, dial it up or off overnight. The cool Peninsula sea breezes can often carry away heat at night – so run the AC less then, and use the chillier air to pre-cool the building before morning.
- Zoning: Make sure unused rooms or zones aren’t air-conditioned. Install zoning controls or simply close vents and doors where possible. No point cooling an empty storeroom!
- Smart Thermostats: Consider a programmable or “smart” thermostat. These let you set different temps for work hours vs weekends. (One Aussie blog notes programming your HVAC can save energy, though we’re paraphrasing common advice here.)
- Fans for Wind-Chill: Run ceiling or pedestal fans to complement the AC. Fans only use about 30–50 watts, whereas an AC unit might use 2000+ watts. The breeze makes you feel cooler, so you can raise the thermostat without feeling hot. In fact, combining fans with your AC can cut air conditioning costs by around 40%. (A full nerdy stat: raising the AC a few degrees and letting fans blow will leave you comfortable and your meter running cooler.)
Consider this table summarizing some energy-saving moves:
| Smart AC Move | Rough Energy Benefit |
|---|---|
| Increase thermostat by 1°C (summer) | ~10% reduction in cooling costs |
| Use ceiling fans with AC | Allows ~4–7°C higher set-point; ~40% less AC usage |
| Regular maintenance | Prevents efficiency drop (clean filters, avoids ~10% loss) |
| Add shading & insulation | Reduces heat gain, easing AC workload |
Applying one or two of these moves can make a noticeable dent in bills – like finding loose change in the couch cushions of your P&L statement.
3. Keep Your System Shipshape
An AC is a machine, and machines need TLC. Regular maintenance is non-negotiable for peak efficiency. Dusty coils or blocked filters force the compressor to work overtime, wasting power. Get HVAC pros to:
- Clean or replace filters monthly (especially critical if your shop is dusty or near the bay breeze).
- Flush condensate lines and clean coils at least yearly (clogged coils are like treading water).
- Check refrigerant levels – leaks not only cut performance but might even incur fines (and costly refills).
- Confirm fans, belts and motors are in good nick; sometimes adjusting a fan speed cuts power draw with no loss of comfort.
If your unit is ancient (say 10+ years), consider upgrading. Today’s inverter-driven chillers can be 30–50% more efficient than a 1990s throwback. Even if a new system costs more upfront, Victorian businesses in the Victorian Energy Upgrades program have saved big. For example, in 2018 about 17,000 businesses took part in government-backed upgrades and each is on track to save roughly $3,700 per year on average. That’s real money — imagine funding a new espresso machine with those savings!
Choosing energy-efficient AC: Look for high energy ratings. In Australia, check the Energy Rating Label: more stars or a high Coefficient of Performance (COP) means a cooler running bill. Premium brands or government-certified models may cost more, but incentives can knock off the price.
For instance, the Victorian Energy Upgrades (VEU) program offers discounts on qualified heating and cooling systems. Small businesses can save up to $500 per year (and large ones up to $74,000) by going electric and efficient via VEU. The state’s program will literally pay you back with rebates on new energy-saving AC units. Talk about a no-brainer.
(Quick tip: If financing is tight, the Environmental Upgrade Finance (EUF) scheme can be a secret weapon. It lets building owners fund green upgrades through council rates – and Mornington Shire is one of many councils on board. The upgrade pays for itself out of the energy savings over time. Worth a look!*)
4. Plug the Leaks (Literally)
This might not sound sexy, but sealing your building envelope is crucial. Every gap around windows, doors or vents is like a tiny money-printing machine (for the energy retailer). Effective draught-proofing and insulation can slash your cooling load by 10–20% or more (some businesses report that big effect from good sealing).
By adding or upgrading insulation in roofs and walls, and installing external shading (like awnings or blinds), you reduce the heat pouring in. Even tinted or reflective window films make a dent. Business Vic underscores this: draught-proofing, insulation and external shading “can help cut costs while improving indoor temperature”.
In practical terms, on a hot Peninsula day, proper shading on the sun-facing side of your building could shave several degrees off the heat load, letting you dial back the AC.
Don’t forget simple habits too: keep doors and windows closed when the AC is on. In office or retail spaces, use door closers or air curtains where doors open a lot (for example, on hot days many shops manually prop the door open and pay for it).
Also, check that vents and ducts are in good order. Leaky ducts (often in the ceiling) can dump cold air into unused crawl spaces or walls – a waste. If you suspect leaks, a pro can perform a pressure test. Fixing holes and gaps means every kW of AC power you generate ends up cooling people, not the roof.
5. Embrace Smart Tech and Habits
Modern buildings can be surprisingly “dumb” about comfort. You can add brains:
- Programmable Timers: Hook your AC to timers or a building management system. Set it so the system only runs during business hours, or gradually ramps down overnight. We’ve seen cafes and shops waste money by leaving AC blasting at 3 am for no reason. A $10 timer or a smart controller can easily prevent that.
- Occupancy Sensors: In some offices or meeting rooms, install motion sensors. If a room is empty, the AC can reduce output or shut off. Every Aussie knows the feeling of an air-conditioned empty meeting room – sensors stop that waste.
- Maintenance Alarms: Use smartphone-connected thermostats that remind you (and your landlord?) when it’s time for a check-up. An ounce of prevention here is heaps of cure.
- Ceiling and Pedestal Fans: We mentioned these earlier because they are such a winner. A gentle fan breeze can make a space feel 3–5°C cooler. The beauty is in the numbers: a typical fan draws only ~30–50W, whereas an AC often guzzles 2000+ W. That’s like comparing a lightbulb to a hair dryer! I once ran the AC less in a busy studio by strategically placing big floor fans; staff stayed happy and the metered load dropped. Bottom line: when people feel that wind-chill effect, you can dial the AC up a bit without complaint.
- Regular Training: Finally, get everyone on board. Train staff to turn off the AC if it’s cool outside or windows are open, and make sure the person who leaves last knows to switch off everything. A little friendly signage (e.g. “Close the door, save our dough!”) can set the right vibe.
6. Tap Into Incentives and Support
Why fight it on your own when government programs exist to lighten the load (and the bill)? In Victoria, both state and federal schemes are goldmines for savvy business owners:
- Victorian Energy Upgrades (VEU): As mentioned, this program rebates efficient appliances. It covers heating and cooling equipment, meaning many air conditioners are eligible. Find an accredited provider (local electricians or HVAC firms often are) to install a qualifying unit, and you’ll pay less upfront. According to Energy Vic, businesses that upgraded through VEU saved on average $3,700 each year.
- Energy Upgrades Vic: Another angle of the VEU is tailored incentives for big projects (called “custom upgrades”). If your business is large or your AC needs revamp, this could net an even higher rebate.
- Small Business Tax Break: The ATO’s Small Business Energy Incentive lets you deduct 20% of the cost of energy-efficient equipment (including air conditioners and fans). That’s like getting a 20% rebate via tax. In a nutshell: if you spend $10,000 on new AC systems (that qualify), you can claim an extra $2,000 off your taxable income.
- Clean Energy Finance: If you’re ready to go big (think rooftop solar or a battery with your AC), agencies like ARENA and the Clean Energy Finance Corporation (CEFC) have financing and grants. Plus, Solar Victoria has rebates for solar panels that effectively power your AC. Why not offset your cooling cost with daylight?
- Local Programs: The Mornington Peninsula Shire and nearby councils sometimes run workshops or audits for businesses. For example, community energy groups (like Repower Mornington Peninsula) offer advice on greening businesses. It’s worth checking the Shire’s website or local business networks for the latest green business initiatives.
In short: You’ve already spent big money on AC to keep customers and staff comfortable. Don’t throw it away! The government will help fund the green, efficient path.

FAQs – Commercial Air Conditioning
What’s the most cost-effective way to reduce commercial air conditioning bills in Mornington Peninsula’s summer?
Start with adjusting the thermostat. Setting your system to 24–25°C instead of 21–22°C can reduce cooling costs by up to 10% per degree. Pair this with ceiling fans and zoning strategies to cut costs further. For many local businesses, simply programming the AC to match business hours and shutting off after close can lead to noticeable savings.
Is ducted or split system air conditioning more efficient for commercial spaces?
It depends on your layout. Split systems are often better for smaller or individual zones (like shops or clinics), offering control and energy savings in specific areas. Ducted systems, on the other hand, are ideal for large open-plan areas or multi-room operations. If not zoned properly, though, ducted systems can waste energy cooling empty spaces, so efficiency depends heavily on design and use.
How often should commercial air conditioning systems be serviced to maintain efficiency?
At least once a year, but ideally quarterly if you’re in a high-use or coastal area like Mornington Peninsula, where salty air and dust can clog filters and coils. Regular maintenance keeps systems running efficiently and avoids energy waste — dirty filters alone can reduce efficiency by 10–15%.
Are there government rebates to help Mornington Peninsula businesses upgrade to energy-efficient AC systems?
Yes! Through the Victorian Energy Upgrades (VEU) program, businesses can access discounts and rebates on approved energy-efficient heating and cooling systems. These upgrades often pay for themselves in under a year through reduced energy bills — and many Mornington-based installers are already VEU-accredited.
