FAQs
How do I know it’s time to replace rather than repair my existing HVAC unit?
Most heating and cooling systems last 10–15 years. If your unit in Mascot is within or beyond this age range, needs frequent repairs, has rising energy bills, or no longer keeps rooms at a stable temperature, replacement is usually the more cost-effective option. A free on-site assessment by our technicians will confirm whether repair or replacement makes better financial sense.
What types of HVAC systems can you replace in Mascot homes and businesses?
We replace all common residential and light-commercial systems, including split-systems, ducted reverse-cycle units, gas furnaces with add-on cooling, packaged rooftop units, multi-head/VRV setups, and heat-pump hot-water systems. We match new equipment to your property’s size, insulation level, and usage patterns to maximise comfort and efficiency.
How long will I be without heating or cooling during an HVAC replacement?
A standard like-for-like split or ducted change-out usually takes one full working day. We remove the old unit, upgrade any required electrical or refrigerant lines, install the new equipment, pressure-test, evacuate and charge the system, and commission it on the same day. For larger or more complex jobs (e.g., new duct layouts or commercial rooftop units) allow 2–3 days. We can provide temporary heaters or portable ACs at no cost if an overnight gap is unavoidable.
What does an HVAC replacement cost in Mascot and what factors affect the price?
For a typical Mascot home, a new high-efficiency split system starts around $4,000 installed, while a full ducted reverse-cycle change-out ranges from $7,500 to $12,000+. Key cost drivers are system capacity (kW), energy-efficiency rating, duct or electrical upgrades, crane access for rooftop units, and any smart-control add-ons. We give fixed-price written quotes so you know the total before work begins and offer 0%-interest payment plans for approved customers.
Are there government rebates or incentives available for new HVAC systems in NSW?
Yes. Under the NSW Energy Savings Scheme (ESS) you may be eligible for rebates when you replace an inefficient unit with a high-efficiency heat pump or inverter system. You can also claim federal Small-scale Technology Certificates (STCs) for qualifying installations, which we process on your behalf and apply as an instant discount. Manufacturers often run seasonal cash-back promotions as well.
What warranties and after-sales support do you provide with a new HVAC installation?
All equipment we install carries a minimum 5-year manufacturer parts and compressor warranty. Our workmanship is covered by a 12-month labour warranty, and you’ll receive a signed compliance certificate and commissioning report on completion. We also offer an optional planned maintenance program: two scheduled services per year, priority breakdown response, and discounted call-out fees to keep your new system performing at its peak.
