The season is decided in April. Becoming visible in July means arriving in the week when everyone is booked out and nobody is searching any more.
People search a unit and a price, not a company. A page per installation type — single split, multi-split, ducted — with a price range and the time on site answers the query exactly as typed.
Servicing is the counterweight to the summer peak. A dedicated page for maintenance contracts fills February and November, when the phone otherwise does not ring.
