FAQs
Which type of cooling system works best for Mascot’s warm, humid summers?
For most homes and small businesses in Mascot, high-efficiency inverter split systems or fully-ducted reverse-cycle systems deliver the best comfort. Both handle temperatures above 30 °C and coastal humidity well, while inverter technology automatically slows the compressor once the set temperature is reached, saving up to 30 % on running costs compared with fixed-speed units.
Why is mechanical ventilation important for indoor air quality?
Modern buildings are sealed tightly to keep conditioned air inside, but that also traps contaminants such as CO₂, dust, and volatile organic compounds (VOCs). A balanced mechanical ventilation system—often called HRV or ERV—exchanges stale indoor air with filtered outdoor air while recovering up to 80 % of the outgoing heat or cooling. The result is lower humidity, fewer allergens, and fresher air with minimal energy loss.
How often should I service my air-conditioning and ventilation equipment?
We recommend a professional tune-up at least once a year before the peak summer season. During a service, our technicians clean coils, check refrigerant pressures, test electrical components, and calibrate thermostats. Washable pre-filters should be cleaned monthly; disposable filters typically need replacing every 2–3 months, or more often if you have pets or allergies.
What is the difference between ducted and split-system air-conditioning?
Split systems have an indoor wall-mounted head and an outdoor condenser. They are cost-effective for single rooms or open living areas. Ducted systems conceal a central indoor unit in the ceiling and distribute air via ducts to every room, giving whole-home climate control, zoning, and a neater aesthetic. Up-front costs are higher for ducted installs, but they add value and can be more efficient for larger homes.
Can upgrading to an energy-efficient unit lower my electricity bill?
Yes. Replacing a 10-year-old air conditioner with a new 5-star-rated inverter model can cut cooling costs by 30–50 %. Look for key features such as variable-speed compressors, R32 refrigerant, and Wi-Fi-enabled smart thermostats. For large premises, adding demand-based ventilation control or installing a heat-recovery ventilator can further reduce energy use without compromising air quality.
Do you provide 24/7 emergency repairs in Mascot?
Absolutely. Our Mascot technicians are on call day and night for breakdowns, gas-smell alerts, or critical ventilation failures. We carry common spare parts in our service vans and aim to restore cooling or heating on the first visit whenever possible. Call our emergency line on 1300 XXX XXX for immediate assistance.
