Questions to Ask Your Tradie

1. Are you experienced with evaporative/air coolers and Legionella-control guidelines?

2. Is the quote inclusive of call-out, labour, cleaning chemicals, replacement pads and VAT?

3. Will you supply a hygiene certificate or written service record?

4. How often should pads or filters be replaced and what do they cost?

5. Do you test pumps, float valves and fans and guarantee repairs for 12 months?

6. What extra charge applies for weekend visits or if a new pump/motor is needed?

7. Can you remind me when the next seasonal service is due?
   

How to Avoid Surprises

• Reserve on-street parking close to the property for the engineer’s van.

• Empty and unplug the cooler before arrival; clear space around the unit.

• Provide safe ladder or loft access if the unit is stored high between seasons.

• Check that an outdoor drain or suitable sink is available for dirty water disposal.

• Notify the tradie about pets, smoke alarms or sensitive electronics near the work area.

• Confirm that service chemicals are low-odour if anyone at home has allergies.
