The Importance of Updating Your Commercial Air Conditioning for Winter – Air Conditioning Perth

In the modern workplace, comfort is more than a luxury—it’s essential for productivity, focus, and the overall wellbeing of your team. As Perth heads into the cooler months, large offices need to ensure their commercial air conditioning systems are not just functional, but performing at their best. An outdated or inefficient system can mean more than just cold fingers and low morale—it can impact health, energy usage, and even your bottom line.

At Dacs Air Conditioning, we understand how crucial it is to keep your workplace running smoothly through the winter season. Whether you manage a large office building, a corporate headquarters, or a multi-storey facility, now is the time to assess, service or even update your commercial air conditioning system. Winter is the perfect opportunity to address your HVAC needs and unlock the many benefits of upgrading or servicing your system.

Air conditioning isn’t just for summer. In large office environments, a reliable heating system is critical for maintaining a consistent and comfortable indoor climate. Unlike homes, offices must cater to a variety of comfort levels and expectations across open-plan spaces, private offices, meeting rooms, and communal areas. If the system isn’t properly zoned, serviced, or designed to handle the demands of a commercial space, employees can quickly become distracted, unwell or uncomfortable. Cold spots, noisy vents, dusty air, and breakdowns can all chip away at efficiency and morale. A robust, modern air conditioning system makes sure your office continues to hum along, no matter how chilly it gets outside.

Older systems often struggle to distribute heat evenly across large or multi-level buildings. Staff working in one corner might be rugged up in jackets while others are opening windows to cool down—far from ideal. Upgrading to a zoned or modern ducted system with smart controls ensures each area gets the right level of heating at the right time, keeping everyone comfortable and productive.

Commercial buildings consume a lot of energy, and heating systems are one of the biggest culprits—especially if they haven’t been updated in years. Modern systems are designed with energy efficiency in mind, using inverter technology, variable speed fans, and smart thermostats to minimise energy use. Over time, the savings on power bills can be substantial.

In winter, windows tend to stay closed, which means we rely on HVAC systems to keep air circulating. An older or unmaintained system can become a breeding ground for dust, mould, and bacteria—all of which are blown through the building. This can contribute to staff illness, allergy flare-ups and even increased sick leave. Upgrading your system or giving it a comprehensive service ensures cleaner, healthier air for your team.

When a heating system fails in the middle of winter, it’s not just a comfort issue—it can bring productivity to a standstill. Staff can’t focus, meetings get disrupted, and workplace safety may even be compromised. New systems are more reliable, and regular servicing drastically reduces the risk of downtime. For busy office environments, that peace of mind is invaluable.

Today’s commercial air conditioning systems often come with smart control features, including remote access, automated scheduling, and integration with building management systems. This not only makes climate control more efficient but also allows facility managers to respond to issues faster and monitor performance in real time.

It’s no secret that a comfortable work environment can improve staff satisfaction. If employees are constantly adjusting thermostats, bringing in personal heaters, or complaining about stuffy air, it can contribute to low morale. Creating a warm, fresh-feeling space in winter helps show that you value your team’s wellbeing.

Not sure if your office air conditioning system is due for an update? Here are a few signs to watch for: uneven heating or cold spots in certain areas, loud or rattling noises from vents or units, rising energy bills despite no major changes in office use, poor airflow or delayed temperature response, frequent repairs or ongoing issues with controls, and system age exceeding 10–15 years. Even if your system is still running, these symptoms could point to inefficiency or wear that’s costing you in the long run.

There are also excellent ways for businesses to track energy savings after updating their HVAC systems. The most straightforward method is comparing energy bills before and after the upgrade, focusing on kWh usage. Installing smart energy monitoring systems or integrating with a Building Management System (BMS) allows for real-time tracking of energy consumption, with some platforms even offering alerts for irregular usage. Many new commercial HVAC units also feature built-in diagnostics and data logging, providing detailed reports on system performance. An independent energy audit before and after the upgrade can also professionally assess savings and confirm your return on investment. Additionally, documenting reduced operational downtime and maintenance costs helps highlight efficiency improvements. Some manufacturers and government bodies offer tools or rebates based on system performance, giving you verifiable savings. And of course, fewer comfort complaints from your staff is always a great sign you’ve made the right move.

Pros of upgrading or servicing your system include keeping staff comfortable and productive, improving energy efficiency, supporting better air quality, avoiding disruption from mid-winter breakdowns, modernising the building, integrating smart technology, and demonstrating a proactive business approach. The main considerations include initial cost and installation timing, but these are often outweighed by long-term savings and increased workplace reliability.
