Summer is here but is your AC ready for the heat?

Sydney summers are known for their intensity, and if your air conditioner struggled last year, now is the ideal time to consider an upgrade. A modern, energy-efficient system will keep your home or business comfortable through the hottest months, while helping you lower running costs and avoid breakdowns when you need cooling the most.

At On Call Air Conditioning & Refrigeration, we specialise in delivering reliable, high-quality installations across the Hawkesbury, Greater Western Sydney and Metropolitan Sydney. Our experienced team ensures that upgrading is simple, efficient and tailored to your needs.

Why Upgrade Now?

Improved cooling performance

If your current system is slow to cool, struggles on high-temperature days or leaves rooms at uneven temperatures, it may no longer be meeting the demands of Sydney’s climate. Newer units are designed for stronger, more consistent cooling output.

Lower energy usage and long-term savings

Older units often work harder than necessary, resulting in higher power bills. Modern air conditioners use the latest inverter technology, offering significant reductions in energy consumption, especially during extended periods of heat.

Avoid costly summer breakdowns

The hottest days put the most strain on older systems. Replacing an ageing unit now helps prevent inconvenient failures and reduces ongoing repair costs during the busiest cooling season.

Better comfort with modern features

New systems generally run quieter, respond faster and offer advanced temperature control options that make day-to-day living more comfortable and efficient.

Save with the NSW Energy Savings Scheme (ESS)

Is your air conditioner more than 10 years old? An older system can be expensive to run and may not include the latest energy-saving technology. Upgrading now allows you to take advantage of the NSW ESS rebates of up to $2,000 for eligible installations.

With the ESS, you can reduce your upfront cost while benefiting from lower energy bills long-term. On Call Air Conditioning & Refrigeration manages the entire process for you, including assessment, eligibility checks, system selection, installation and all required paperwork. Your upgrade becomes completely stress-free and fully compliant.
