Get HVAC approvals signed without adding another monthly platform.
Use the estimates, service agreements and authorization PDFs your HVAC business already has. PocketESign adds the signing workflow: fields, secure link, status tracking and completed record.
The document already exists. The approval is the missing step.
HVAC work can move from diagnosis to approval quickly: an equipment change, inaccessible ductwork, a failed component or an owner request can alter scope while the technician is still on site. The useful part of e-signature software is not a giant CRM — it is making the written approval easy to send and easy to retrieve later.
Estimate or proposal approval
Capture customer acceptance before ordering equipment or scheduling installation.
Additional-work authorization
Document work discovered after diagnosis, including price and scope changes.
Service agreement
Send maintenance or recurring-service terms without printing and scanning.
Equipment / option acknowledgement
Record the selected equipment, efficiency tier or optional upgrade the customer approved.
No CRM migration required.
Seasonality makes recurring software especially awkward. If your signing volume rises during heating or cooling peaks and drops afterward, PocketESign credits stay available instead of turning into another monthly bill.
PocketESign is intentionally not dispatch, inventory, invoicing or HVAC estimating software. If you already have those tools — or simply work from PDFs — it supplies the missing signature layer without asking you to migrate the rest of your operation.

Practical questions before you send.
Can an HVAC customer sign from a phone?
Yes. Recipients open a secure signing link in their browser and do not need a PocketESign account.
Can I use my existing HVAC estimate or service-agreement PDF?
Yes. Upload the PDF you already use, then place signature, date, text, initials or checkbox fields visually.
Do I need a monthly plan for seasonal HVAC volume?
No. PocketESign uses one-time credit packs and unused credits do not expire.
Keep the document you trust. Make the signature easier.
