Upgrades for existing commercial HVAC & Pool Heating
Expert upgrades for safer, smarter, and more efficient commercial climate systems.
Upgrading your HVAC or pool heating system doesn’t just improve performance — it reduces risk, lowers energy costs, and extends the life of your infrastructure. At Image Air Conditioning, we deliver practical, efficient upgrade solutions tailored to commercial and government facilities across NSW. Whether you’re replacing ageing systems, switching from gas to electric, or addressing compliance or temperature stability concerns, we provide advice, design input, and hands-on delivery to ensure your upgrade is done right.
Smarter HVAC & Pool Heating Upgrades for Commercial Sites
When it comes to upgrading commercial HVAC or pool heating systems, performance and compliance go hand in hand. Whether you’re replacing ageing plant, transitioning from gas to electric, or addressing temperature instability, a well-designed upgrade can cut energy costs, reduce downtime, and simplify future maintenance.
At Image Air Conditioning, we understand how older systems can create hidden inefficiencies — from inconsistent airflow and outdated controls to overworked heating units and hard-to-service pipework. That’s why every upgrade we deliver is tailored to the site’s layout, energy targets, and long-term serviceability.
Many businesses operate seven days a week and simply can’t afford unexpected downtime. That’s why Mark Greentree takes a proactive, solutions-focused approach to upgrade works and system improvements. Through clear communication, direct consultation with on-site management, and careful planning, Mark develops tailored strategies to minimise disruption and maintain operational continuity. From after-hours staging to smart equipment sequencing and temporary service support, each solution is designed to reduce impact on your day-to-day operations without compromising safety, quality, or compliance.
We deliver HVAC & pool heating upgrades that:
- Replace inefficient or ageing equipment with modern, energy-saving solutions from trusted brands like Daikin, Fujitsu, EvoHeat, and Temperzone.
- Improve comfort and air/water temperature stability across the year
- Meet current WHS, electrical, recycling, and environmental standards
- Integrate smart controls, zoning, and variable speed flow control
- Simplify future servicing with improved access and commissioning features
Upgrading to advanced inverter heat pump technology can deliver dramatic improvements in energy efficiency. For example, the EvoHeat Evo CS-i Series commercial heat pump offers a Coefficient of Performance (COP) of up to 16 — meaning for every 1kW of power input, it can deliver up to 16kW of heat output. This translates into lower operating costs, reduced emissions, and a faster return on investment compared to gas or fixed-speed systems.
We also consider operational cost savings and long-term compliance benefits by aligning with government energy targets such as those outlined by
NSW Climate and Energy Action.
With over 35 years of experience, Mark Greentree personally reviews each site and upgrade specification, ensuring solutions are technically sound, practically built, and aligned with your operational needs. We collaborate with councils, engineers, facility managers, and builders to deliver upgrades that work — and keep working.
Whether you’re upgrading pool heating for a swim school, electrifying a high-rise system, or improving air quality in a public building, we’ll help you transition with confidence and compliance.

FAQ's
What types of upgrades does Image Air specialise in?
We specialise in high-efficiency HVAC and pool heating upgrades for commercial and government clients. Our focus includes replacing outdated gas-based systems with electric alternatives, integrating smart controls, improving airflow and thermal stability, and enhancing long-term serviceability. Each solution is designed by Mark Greentree to deliver energy savings, reduce maintenance needs, and align with WHS and environmental standards.
How do your upgrades improve energy efficiency?
We use the latest full inverter technology and advanced control systems to reduce energy use without compromising performance. For example, EvoHeat heat pumps offer a Coefficient of Performance (COP) of up to 16 — meaning 1kW of energy input delivers up to 16kW of output. Our systems operate intelligently, using zoning and variable speed control to adapt to load, further improving efficiency and cutting running costs.
How do you minimise disruption to business operations during upgrade works?
We understand that many commercial sites operate seven days a week and can’t afford unexpected downtime. Mark Greentree works closely with clients to minimise disruptions through clear communication, consultation with management, and tailored planning. Techniques may include after-hours work, staged upgrades, temporary service provisions, and careful sequencing of system shutdowns. These strategies ensure essential services remain operational while upgrade works are safely and efficiently delivered.
Why is serviceability such a big focus in your upgrade designs?
Many system failures and costly maintenance issues arise from poor access, tight layouts, or overly complex installations. Mark personally reviews every upgrade plan to ensure components are logically placed, safely accessible, and future-proofed for ongoing maintenance. This reduces risk, minimises future downtime, and ensures clients get the best return on their investment.
Are your upgrades eligible for government or council funding?
Yes, in many cases. We stay up to date with programs like the Community Energy Upgrades Fund and can design systems that align with grant or tender requirements. Our team can assist with technical input for submissions and ensure documentation supports funding criteria such as environmental targets and safety compliance.
What brands or equipment do you recommend?
We partner with EvoHeat, one of Australia’s most trusted manufacturers of high-performance heat pumps specifically engineered for commercial pool applications. Their systems deliver excellent energy efficiency, rapid temperature recovery, and advanced controls — making them ideal for councils, aquatic centres, schools, and high-use facilities.
EvoHeat’s commercial range supports both new installations and electrification upgrades, with a proven track record in demanding Australian conditions.
Learn more about EvoHeat’s commercial pool heater systems on their official website.
While we tailor every system to suit each site, EvoHeat remains our preferred brand due to their reliability, smart performance features, and strong service support across NSW.
Do you offer compliance documentation for tenders or WHS?
