FAQs
What types of commercial chillers do you supply and install in Mascot?
We provide, install and service both air-cooled and water-cooled chillers ranging from 20 kW packaged units to multi-megawatt central plant systems. Each chiller is selected to match the building load profile, available space, local water restrictions and energy-efficiency targets that apply in Mascot and the wider Sydney area.
How do I determine the correct capacity for my building’s chiller?
Our engineers perform a detailed heat-load calculation that factors in building size, occupancy levels, equipment heat gain, local climate data for Mascot and any future expansion plans. We then recommend a chiller with enough capacity to meet peak summer demand while operating efficiently during part-load conditions, often pairing the main unit with variable-speed drives or multiple compressor circuits for better turndown.
What routine maintenance does a commercial chiller require?
To maximise reliability and lifespan, we recommend quarterly inspections that include condenser/evaporator coil cleaning, refrigerant charge checks, water-treatment testing, vibration analysis and verification of safety controls. Annual tasks add oil sampling, tube brushing for water-cooled units and recalibration of sensors. Our Mascot-based technicians log all readings so trends can be detected before they become costly breakdowns.
Can upgrading my chiller reduce operating costs and carbon emissions?
Yes. Modern chillers use high-efficiency magnetic-bearing compressors, low-GWP refrigerants and advanced control algorithms that can cut energy consumption by 30–50 % compared with units installed more than 10 years ago. In Mascot, these savings are amplified by high electricity tariffs, and you may qualify for NSW Energy Saving Scheme (ESS) incentives that lower upfront costs while shrinking your carbon footprint.
How long does a typical chiller replacement take from order to commissioning?
For most mid-size commercial buildings in Mascot, allow 10–14 weeks: 2–3 weeks for detailed design and equipment selection, 4–6 weeks for factory lead time, and 2–3 weeks for on-site works—including demolition, crane lifts, piping, electrical tie-ins and controls integration—followed by performance testing and final commissioning. We can provide temporary cooling solutions to keep tenants comfortable during the change-over.
Do you offer 24/7 emergency service for chiller and HVAC breakdowns?
Absolutely. Our Mascot service team is on call 24 hours a day, 365 days a year. Technicians carry common spare parts and diagnostic equipment, enabling us to resolve most faults on the first visit. We also maintain direct access to OEM inventories for rapid procurement of critical components, minimising downtime for your tenants or process cooling operations.
