In the hot months, demand for installation and repairs doubles within days, and a company taking requests by phone loses half of them in the rush. A request page that captures the address, unit type and fault means every job arrives complete, even when the lines are busy.
Annual maintenance contracts are the steady income that carries you through winter. But a contract whose visits are forgotten turns into a complaint, and the customer will not renew. When each contract has its dates and the system warns you before every visit, renewals almost take care of themselves.
A technician who arrives knowing the unit model and its last service, carrying the right part, finishes on the first visit. That saves trips and makes customers feel they are dealing with a company, not a lone technician.
