Common questions
Booking air con & heating on Knockr
How much does air conditioning service cost in Australia?
A standard residential split-system service on Knockr runs $150–$250 AUD including filter clean, coil clean and refrigerant check. Fault diagnosis is typically $120–$200. New installations (2.5–5kW split system supplied and installed) run $900–$1,800 depending on the brand and installation complexity.
How often should I service my air conditioner?
Most manufacturers recommend a professional service every 12 months for residential systems and every 6 months for commercial or heavily-used systems. A clean, serviced system uses up to 25% less electricity than a dirty one.
Why is my air conditioner not cooling?
Common causes include a dirty filter (clean or replace it), low refrigerant (requires a licensed tech), a frozen evaporator coil, or a faulty compressor. Post a request on Knockr and a technician can diagnose the issue in person.
Do I need a licensed tech to add refrigerant?
Yes — handling refrigerants requires an ARC Refrigerant Handling Licence under Australian law. All Knockr HVAC technicians are ARC-licensed for refrigerant work.
Can Knockr help with ducted air conditioning?
Yes. Filter-and-return servicing and minor repairs are available through Knockr. Full ducted system replacements and new duct runs typically require a site inspection first — post a request and a qualified technician will come to assess.
