HVAC Rough-In Checklist
HVAC Rough-In Checklist
Quick Summary
An HVAC rough-in checklist helps crews verify that ductwork, equipment locations, refrigerant lines, drains, and ventilation components are installed correctly before finishes are installed. It helps identify coordination issues, installation errors, and missing components early in the project. This checklist is useful for HVAC contractors, foremen, installers, and project managers working on residential or commercial jobs.
When to Use This Checklist
- Before HVAC rough-in work begins.
- During ductwork and equipment installation.
- Prior to rough-in inspections.
- Before insulation and drywall installation.
- After layout changes or field revisions.
- As part of internal quality control reviews.
Before You Start
- Review approved HVAC plans, specifications, and equipment schedules.
- Verify framing and structural work are ready for rough-in.
- Confirm equipment locations and clearances.
- Verify ductwork, fittings, and materials are onsite.
- Coordinate installation routes with plumbing, electrical, and framing trades.
- Review inspection requirements and project milestones.
- Inspect materials for damage before installation.
- Verify access to attic, ceiling, mechanical room, or crawlspace work areas.
Safety Checks
- Inspect ladders, lifts, and access equipment before use.
- Verify power tools and cutting equipment are in safe condition.
- Maintain clear work areas free of duct scraps and debris.
- Use proper lifting methods when handling HVAC equipment.
- Verify workers are using required PPE.
- Identify overhead work hazards and confined access areas.
- Coordinate work activities with nearby trades.
Tools, Equipment, and Materials
- Ductwork, fittings, and connectors.
- Air handlers, furnaces, or HVAC equipment.
- Refrigerant line materials and fittings.
- Condensate drain piping and accessories.
- Supports, hangers, and mounting hardware.
- Layout, measuring, and cutting tools.
- Project drawings, equipment schedules, and inspection forms.
HVAC Rough-In Checklist
- Verify HVAC layout matches approved plans.
- Confirm equipment locations and service clearances.
- Inspect ductwork routing for proper placement.
- Verify supply and return duct locations.
- Confirm duct connections are secure and properly sealed.
- Inspect duct supports and hanging systems.
- Verify refrigerant line routing and protection.
- Confirm condensate drain installation and slope.
- Inspect equipment mounting and support structures.
- Verify thermostat and control locations.
- Check for conflicts with plumbing, framing, or electrical systems.
- Confirm required penetrations are complete and properly located.
- Inspect work for damage, missing components, or installation defects.
- Document field changes and approved revisions.
- Complete internal quality control review before inspection.
Documentation Needed
- Approved HVAC drawings and specifications.
- Equipment schedules and submittals.
- Inspection reports and approvals.
- Photos of completed rough-in work.
- Field revision and change documentation.
- Quality control and punch list records.
Common Mistakes to Avoid
- Installing ductwork without verifying layout dimensions.
- Poor coordination with other trades.
- Improper equipment clearances.
- Loose or poorly sealed duct connections.
- Improper condensate drain routing or slope.
- Failing to document field changes before inspection.
End-of-Day / Final Review
- Ductwork and equipment rough-in have been completed for the scheduled area.
- Supports, connections, and routing have been verified.
- Work areas have been cleaned and organized.
- Photos and project documentation have been completed.
- Outstanding deficiencies have been corrected or documented.
- The HVAC rough-in is ready for inspection or the next phase of construction.
