HVAC fab shop software in 2026: a buyer's checklist
By Field to Fab Team
There are a lot of options for HVAC fab shops who want to retire the spiral notebook on the magnetic clipboard. Most are bad. The market is full of generic project tools that were not built for sheet metal, and a smaller number of legacy installs that were built for it 20 years ago and never updated. Here is the short list of questions that separates real tools from sales decks.
Does it run on a phone in a basement with no signal? Trades software that breaks the moment connectivity drops is a non-starter. Look for a real PWA with an offline banner, an installable home-screen icon, and a measurement form that does not POST every keystroke.
Does it understand sheet-metal geometry, or did somebody just bolt a CAD viewer on a generic CRM? Ask the vendor to render a 12 x 8 rect elbow with a 6 in throat. If they cannot do it natively without uploading a DWG, walk away.
Does the cut-sheet PDF look like something a brake operator can read? Ask for a real example. If the answer is a screenshot of a Kanban card, walk away.
Is the data isolated per shop at the database level? RLS is the table stakes here. "Trust us" is not isolation. Anything less than database-level multi-tenant isolation puts your shop's measurements one bug away from a competitor's read query.
Can you export everything? If the vendor disappears tomorrow, can you get your orders, photos, and measurements back as files? The right answer is yes, in CSV or JSON, no support ticket required.
Does the pricing scale with shops or with seats? Per-seat pricing punishes you for putting more Field Foremen in the field — exactly the wrong incentive. Look for per-shop pricing.
