Heat is the calendar. Perth summers are long, hot and dry, and a run of 40-degree days sends aircon repair calls up while pest activity and solar interest shift with the seasons. Termites are a real concern in Western Australia, so many owners book inspections.
Coastal houses along the northern and southern coasts, newer estates in the east and apartments near the river each bring different jobs. Solar is well established on Perth roofs, so a new quote competes with a lot of local advertising.
Aircon, electrical and plumbing work must be done by licensed people, and a page that shows your licence builds confidence. Distances are long, so a crew in Joondalup and one in Rockingham serve different customers.
