Questions from HVAC teams.
Visit the Help CenterCan I schedule recurring maintenance visits?
Yes. Create a recurring job and choose how often visits repeat. Each visit stays on that job, with its schedule and visit details.
Can I use my price book and offer optional items?
Yes. The price book prices the repair on the tech's phone, and an estimate can carry optional items the customer picks on the estimate itself, like duct sealing, UV lights, dehumidifiers and smart thermostats. Every unaccepted estimate stays in one list until the customer accepts or declines.
How do deposits and customer payments work?
Customers pay by card from the invoice you email them, straight into your own Stripe account. A deposit on a changeout is recorded against that invoice, and so are partial payments, cash and checks.
Can I mix residential and commercial work?
Yes. A commercial account keeps several properties, on the same records as your residential customers. Each invoice carries its own payment terms, such as Net 30. Warranty work is marked no invoice, with the reason, instead of being billed wrong.
What can I bring over from my current system?
Your customers come over from the app you use now or a spreadsheet, along with their jobs and invoices. You check a preview before anything is added, and everything you enter stays yours. See how switching works.
What does setup involve for my crew?
Create the account, add each person with a role, and they sign in on their own phones. The Help Center walks through each step, and the support page has chat, email and the support line when you want a hand.
