HVAC Scope of Work Template
Download an HVAC scope of work template to define equipment, ductwork, piping, controls, testing, trade responsibilities, exclusions, scheduling, and closeout requirements.
Define HVAC Responsibilities Before Work Begins
An HVAC scope of work gives contractors, subcontractors, owners, and project teams a clear description of the mechanical work included in a project. It defines equipment, ductwork, piping, controls, insulation, testing, trade responsibilities, schedule requirements, exclusions, and closeout deliverables before crews mobilize.
This HVAC Scope of Work Template is designed for HVAC subcontractors, mechanical contractors, sheet metal contractors, refrigeration contractors, controls contractors, general contractors, estimators, project managers, superintendents, and owners preparing or reviewing HVAC agreements.
What Is an HVAC Scope of Work?
An HVAC scope of work is a detailed description of the labor, equipment, materials, services, coordination, and deliverables required for a heating, cooling, ventilation, refrigeration, or controls project. It establishes the boundaries of the HVAC contractor’s work and identifies the drawings, specifications, addenda, approved submittals, assumptions, allowances, exclusions, and acceptance requirements that apply.
A complete scope may address demolition, rooftop units, air handlers, furnaces, boilers, chillers, heat pumps, ductwork, dampers, diffusers, refrigerant piping, hydronic piping, condensate drainage, controls, insulation, rigging, testing, balancing, startup, commissioning, training, and closeout. It should also define interfaces with electrical, plumbing, roofing, structural, firestopping, controls, ceiling, drywall, and commissioning work.

| Testing and Commissioning | Lists pressure tests, leak tests, startup, air balancing, hydronic balancing, controls testing, commissioning, and final reports. |
| Schedule and Shutdowns | Records release dates, long-lead items, phasing, shutdown windows, work hours, milestones, and coordination requirements. |
| Closeout and Warranty | Defines equipment labeling, record drawings, O&M manuals, training, warranties, punch-list work, and final turnover. |
| Exclusions and Work by Others | Clarifies electrical power, structural steel, roofing, curbs, patching, firestopping, controls, utilities, and other excluded work. |
How to Use the Template
- Enter the project, HVAC contractor, customer, contract information, work areas, and governing documents.
- Separate the scope by HVAC system, building, floor, room, zone, phase, or bid package.
- Define demolition, shutdown, temporary HVAC, and existing-system protection requirements.
- Describe equipment, ductwork, piping, insulation, supports, controls, and accessories.
- Assign responsibility for curbs, roof penetrations, structural supports, power wiring, condensate connections, and firestopping.
- Identify equipment manufacturers, capacities, accessories, installation methods, and labeling requirements.
- List required submittals, inspections, startup procedures, tests, balancing, commissioning, and acceptance criteria.
- Document lead times, release dates, crane dates, shutdown windows, work hours, access, and coordination milestones.
- Separate included work, allowances, alternates, unit prices, exclusions, and work by others.
- Review the completed scope against the estimate, proposal, and final agreement before approval.
An HVAC subcontractor is awarded the mechanical package for a two-story clinic renovation. The scope includes selective demolition, two rooftop units, VAV boxes, supply and return ductwork, exhaust systems, refrigerant piping, condensate drainage, duct insulation, controls rough-in, startup, air balancing, commissioning support, equipment labeling, and record drawings. Electrical feeders, structural roof reinforcing, roofing repairs, firestopping, and final BAS programming are identified as work by others unless added by written change order.
Best Practices for HVAC Scopes of Work
- Organize the scope by HVAC system and project area.
- Reference the latest drawings, specifications, addenda, and approved submittals.
- Identify equipment manufacturers, capacities, accessories, and control requirements.
- Define who provides curbs, roof penetrations, structural supports, power, and controls wiring.
- Assign responsibility for crane use, rigging, hoisting, delivery, and storage.
- Document insulation, firestopping, access-door, sealing, and labeling requirements.
- Define shutdown, temporary HVAC, occupied-space, and infection-control requirements.
- List startup, test and balance, commissioning, training, and closeout obligations.
- Separate included work, allowances, alternates, exclusions, and work by others.
- Preserve revisions and written approvals when the scope changes.
Common HVAC Scope of Work Mistakes
- Using broad language such as “complete HVAC work” without system details
- Failing to identify drawings, specifications, addenda, and equipment schedules
- Leaving curbs, roofing, structural supports, and electrical power undefined
- Omitting crane, rigging, hoisting, and equipment-delivery responsibilities
- Failing to define controls, BAS, and control-wiring boundaries
- Leaving insulation, sealing, firestopping, and access-door responsibilities unclear
- Omitting shutdowns, temporary HVAC, or occupied-space requirements
- Failing to include startup, balancing, commissioning, and training
- Ignoring long-lead equipment and material-release milestones
- Changing the scope without a documented revision or change order
Frequently Asked Questions
What is the purpose of an HVAC scope of work?
It defines the HVAC contractor’s systems, equipment, responsibilities, work limits, installation requirements, coordination duties, deliverables, exclusions, and acceptance criteria before work begins.
Should HVAC systems be listed separately?
Yes. Separate heating, cooling, ventilation, air distribution, hydronic systems, refrigerant systems, controls, exhaust, makeup air, temporary HVAC, and specialty systems where applicable.
How should equipment responsibilities be described?
Identify who furnishes, receives, stores, rigs, sets, connects, starts, tests, commissions, and warrants each equipment item.
Who provides roof curbs and structural supports?
The agreement should assign these responsibilities explicitly. Depending on the project, they may be included in the HVAC scope or assigned to roofing, structural, or general-contracting trades.
How should controls and BAS integration be handled?
Define responsibility for control panels, sensors, actuators, control wiring, programming, sequences, graphics, network integration, startup, testing, and final commissioning.
What testing should be included?
Depending on the project, testing may include duct leakage, pressure testing, refrigerant leak testing, hydronic flushing, airflow testing, air balancing, hydronic balancing, controls testing, equipment startup, and functional performance testing.
What should be listed as work by others?
Common examples include electrical feeders, disconnects, roof curbs, roofing repairs, structural steel, concrete pads, patching, firestopping, BAS programming, utility work, and hazardous-material removal.
When should the HVAC scope be revised?
Revise it when drawings, equipment, quantities, controls, shutdown requirements, schedule, testing, or trade responsibilities change. Preserve the prior version and document approval.
