Sound familiar?
Running a HVAC business is hard enough
The heatwave phone melts
The first hot week of the year and every phone line rings at once. Missed calls are jobs your competitor takes.
Maintenance plans slip
Annual services promised at install are forgotten by everyone, and the recurring revenue quietly evaporates.
Wrong unit, wrong parts
Arriving without knowing the system model means a diagnosis visit plus a parts trip. Two visits, one invoice.
Service call booking
The rush books itself
Customers book service calls online with the unit details on the intake form. The WhatsApp assistant absorbs the seasonal flood and your calendar fills in real time.
- Online booking for service calls
- Unit details and photos at booking
- WhatsApp AI handles the enquiry rush
Maintenance plans
Recurring services that never slip
Put every maintenance contract on a recurring schedule. Customers get reminders, you get a predictable base load, and the recurring revenue stops leaking.
- Recurring bookings per contract
- Automatic reminders before visits
- Contract history per customer
Prepared visits

Model numbers, install dates, and past services live on the customer record. You arrive with the right gas and the right parts, and one visit closes the job.

Can I run annual maintenance contracts?
Yes. Set each contract as a recurring booking at its cadence. Customers get reminded before each visit and the work lands on the assigned technician's calendar automatically.
Can customers tell me their unit model when booking?
