HVAC software for crews that work in the field
HVAC contractors use FieldSub to schedule service and install jobs, keep customer history attached to each property, and get paid faster with clear field-to-office handoffs.
Why hvac teams choose FieldSub
- Estimate from the field with photos and notes attached to the job
- Schedule crews and keep office ↔ site updates in Spanish or English
- Invoice with closeout proof already attached — get paid faster
Installs and service calls on one calendar
A two-day install and a forty-minute no-cool call live on the same schedule. Assign the install crew as a crew and the service tech as a person, and each sees only their own day, in Spanish or English, with the property's history attached.
Quote the system, not just the box
Equipment, line set, pad, disconnect, permit and labor go in as line items with your pricing, so the homeowner sees a complete number and you keep your margin visible. Send it from the driveway; approval comes back to your phone.
Every property remembers its equipment
Photos of the nameplate and the install stay on the property record, so the next tech knows what is on the roof before climbing up. Invoices sync to QuickBooks, and clients pay online through the QuickBooks pay link or from a recorded check.
Built for bilingual field operations
FieldSub is Spanish-first field service software for hvac subcontractors and growing crews in the U.S. Run the office in English, the site in Spanish — or the other way around — without losing the job record.
