FAQ
How much is the HVAC Stack?
$13 per month after a 14-day free trial. Cancel anytime. Includes the estimate builder, job tracker, invoice generator, daily log, sub list, and document storage. Trade-specific fields include equipment model, tonnage, refrigerant type, EPA 608 cert #, and warranty info.
What HVAC-specific fields are built into estimates?
Estimate templates capture equipment model, tonnage, refrigerant type, EPA 608 cert # for the tech assigned, and warranty info (parts/labor term). Labor line items track tech hours separate from material line items.
Can I track refrigerant usage per job?
Yes. Each estimate and log entry can capture refrigerant type and quantity (lbs). Useful for compliance audits and EPA recordkeeping.
Do technicians need their own account?
No. The sub & crew list has a tech roster with EPA 608 cert #s, and you assign them to jobs directly. Customers see only their own estimator / installer.
Can I attach commissioning sheets and OEM warranty docs?
Yes. Document storage accepts PDFs and photos per job — commissioning sheets, OEM warranty registrations, refrigerant tracking logs, and before/after photos all live next to the job record.
