Keep project records in one place
HVAC change orders lose value when the backup is not organized.
Duct routes conflict with structure. Equipment locations shift. Controls are added after the original scope is approved. Access panels are required where none were planned. When field changes are not captured quickly, the extra labor and materials can become hard to bill and easy to dispute.
A Change Order System Built for HVAC Contractors
Doxlair gives your team a simple place to organize the change, reason, notes, project details, and documentation before the money slips through the cracks.
Capture Mechanical Field Changes
Document duct reroutes, equipment changes, access requirements, added runs, controls changes, and coordination conflicts as they are discovered.
Connect Supporting Details
Keep notes, equipment information, photos, and cost context tied to each change so billing is backed by organized documentation.
Score Each Change Order
Doxlair scores HVAC change orders and shows weak areas — equipment details, location, reason, materials, labor, and schedule impact — before you send.
