What HVAC Service Manager does
HVAC Service Manager is an offline field service app for HVAC contractors, heating and cooling technicians and installers. It assigns a technician to each job, prints work orders with labor and parts, keeps each unit's serial number and warranty on file, flags maintenance agreement renewals, tracks van stock, and turns estimates into jobs and invoices. It runs offline on one computer, laptop or tablet, with records kept on that device.

Questions
Something else? Email us and we'll answer before you buy.
Can technicians use it on a tablet or laptop in the van?
Yes. It runs with no internet, so a technician can look up a customer’s equipment and fill in a work order with no signal. Each device keeps its own records, so use a backup file to move them between machines.
Does it record refrigerant added or recovered?
Not as a separate log. The equipment record holds the refrigerant type and capacity, and the work order has free-text fields for the diagnosis and the work performed, which is where technicians usually note charge and recovery figures.
Can I put my company name and license number on invoices?
Yes. Open Settings and fill in your business name, phone, email, address, tax number and contractor license. They appear on work orders, estimates and invoices, along with your invoice, estimate and job number prefixes.
How do I move everything to a new office computer?
On the old machine open Settings → Your data & backups and click "Download a backup (.json)". On the new one, open the app and click "Restore from a backup", then pick the file.
Can I track parts on the vans?
Yes. Parts & inventory holds cost, selling price, where each part is stored and the minimum stock level, and flags anything at or below it so you know what to reorder.
Can several people use it at the same time?
No. It is made for one person on one device, and records do not sync between devices. To move to another device, save a backup and restore it there.
Can customers book or pay online through it?
No. It runs offline on your own device, so there is no booking page for customers and it does not take card payments. You record bookings and payments in it yourself, including ones taken by phone, card reader or another website.
