Time on Site

 

Most assessments take 1–2 hours on site for a single split system; longer if there are multiple indoor units, restricted access to the outdoor unit or the engineer needs to trace a refrigerant leak or dig out service history

 

Questions to Ask Your Tradie

 

• are you f‑gas certified and insured to work on my system

• will you provide a written report with photos and measured readings after the visit

• what does your call‑out fee cover and how do you charge for additional labour or testing

• do you need roof or loft access and can you provide safe working‑at‑height equipment if required

• will checks for refrigerant levels or leaks incur extra charges and how are any refrigerants handled/disposed

• can you give a ballpark cost for common follow‑up repairs so I can budget

 

How to Avoid Surprises

 

• clear space around indoor and outdoor units so the engineer can work safely

• leave access to the consumer unit, isolator and thermostat and bring any previous service records

• reserve close parking or advise of access restrictions so engineers can bring ladders/test kit

• secure pets and inform the engineer of restricted areas or landlord/managing‑agent rules

• advise the engineer beforehand of known issues such as noises, recent leaks or intermittent faults
