FAQs
What types of air-conditioning systems do you install and service in Mascot?
Our Precision Engineering Heating & Air Conditioning team works with every major residential and light-commercial system used in the Mascot area, including high-wall split systems, multi-splits, fully ducted reverse-cycle units, VRV/VRF systems, packaged rooftop units and specialised server-room cooling. Whether you need a brand-new design and installation, a retrofit to replace ageing equipment, or routine maintenance on an existing unit, we have the licences, diagnostic tools and factory training to keep your preferred system running at peak efficiency.
How often should my air conditioner be serviced?
For home installations we recommend a comprehensive service every 12 months, ideally in early spring before the cooling season. Commercial sites with higher run hours or critical temperature requirements (e.g., server rooms, restaurants) should be inspected quarterly. Regular servicing includes cleaning indoor coils, flushing the condensate drain, checking refrigerant pressures, testing all electrical components, calibrating thermostats and verifying airflow. Preventive maintenance can reduce power consumption by up to 20 %, extend equipment life and keep manufacturer warranties valid.
Are your technicians fully licensed and insured in NSW?
Yes. Every technician who attends a Mascot job holds a current ARCtick refrigerant handling licence, NSW Restricted Electrical Licence and White Card. Precision Engineering Heating & Air Conditioning also maintains $20 million public liability insurance and workers’ compensation coverage. Copies of licences and insurance certificates can be provided on request, giving you complete peace of mind that your installation or repair meets all safety and regulatory requirements.
Can you improve the energy efficiency of my existing system without replacing it?
In many cases, yes. Our technicians can perform a detailed energy audit to identify quick-win upgrades such as zoning dampers, smart Wi-Fi controllers, variable-speed (EC) fan motors, refrigerant charge optimisation and duct sealing. We also offer chemical coil cleaning and airflow balancing, both of which can restore 5–15 % lost efficiency. If your compressor and heat-exchanger are still in good condition, these enhancements may delay a full replacement for several years while cutting running costs immediately.
How quickly can you respond to breakdowns in Mascot?
Because our depot is less than 10 minutes from the Mascot CBD, we guarantee same-day response for calls logged before 2 pm, and 24/7 after-hours emergency service for critical failures. Our vans carry the most common PCB boards, capacitors, contactors, sensors and refrigerants, allowing us to resolve 85 % of faults on the first visit. For parts we don’t stock, we have established relationships with Sydney wholesalers to source components overnight whenever possible.
Which air-conditioning brands do you recommend and what warranty do they carry?
We are authorised dealers for Daikin, Mitsubishi Electric, Fujitsu, Panasonic and ActronAir. These manufacturers consistently score highest in reliability studies and offer advanced inverter technology suited to Sydney’s climate. Standard residential warranties range from 5 to 7 years on parts and labour when installed and maintained by an authorised dealer—so your investment is protected. We can also supply commercial-grade equipment from Temperzone, Toshiba and Hitachi, each backed by comprehensive factory support and extended warranty options.
