01 / HVAC engineering
Comfort is the outcome. Coordination is how the system gets there.
An HVAC system must respond to occupancy, internal loads, outdoor conditions and the physical limits of the building. 4MS brings those inputs together into a practical system strategy and clear documentation.
Ventilation
Outdoor air, exhaust and make-up air coordinated for occupied and specialized spaces.
Constructability
Equipment and duct routes developed within real ceiling, roof and service-space constraints.
Operation
System zoning, access and control intent considered as part of the building design.
02 / Capabilities
HVAC design from loads to air distribution.
The design scope is shaped around the building, occupancy, existing equipment, project constraints and approval requirements.
System foundation
Load Calculations & Equipment Sizing
Heating and cooling demand evaluated to support appropriate system and equipment decisions.
Indoor environment
Heating & Cooling
System approaches and distribution layouts developed around comfort and building use.
Air quality
Ventilation & Outdoor Air
Outdoor-air requirements and delivery coordinated with occupancy and system operation.
Specialized air
Exhaust & Make-Up Air
General and specialized exhaust coordinated with replacement air where applicable.
Distribution
Ductwork & Air Devices
Supply, return and exhaust routes aligned with ceilings, structure and other services.
Documentation
Permit & Construction Drawings
Coordinated HVAC drawings prepared for review, pricing and construction workflows.
03 / Airflow strategy
Follow the air through the building.
Good HVAC design considers the complete path—from outdoor conditions and equipment through distribution, occupied zones, return and exhaust. Each part affects comfort, ventilation and system performance.

Project inputs
Review drawings, use, occupancy, equipment and existing information.
- 02
Loads & ventilation
Assess heating, cooling, outdoor air and exhaust requirements.
- 03
System selection
Establish an approach suited to the space and project constraints.
- 04
Layout & coordination
Develop equipment, ductwork and air-device layouts with other disciplines.
- 05
Documentation
Prepare permit-ready and construction-focused HVAC drawings.
- 06
Project support
Assist with applicable review comments and construction questions.

07 / Common questions
HVAC design FAQs.
Not sure what the project requires? Start with the floor plans, intended use and any available information about the existing system.
Do I need HVAC drawings for a commercial renovation?+
Requirements depend on the project scope, building and authority. A scope review can clarify whether mechanical drawings and calculations are likely required.
Can you review an existing HVAC system?+
Available drawings, equipment information and site conditions can be reviewed to understand how an existing system relates to the proposed use.
Do you design restaurant exhaust systems?+
Restaurant projects can include kitchen exhaust, make-up air, equipment coordination and related mechanical calculations where applicable.
Can you prepare HVAC permit drawings?+
Yes. 4MS prepares permit-ready HVAC documentation and can support responses to applicable municipal comments. Approval remains with the authority.
Can you coordinate with architects and contractors?+
Yes. HVAC documentation can be coordinated with architects, contractors and other engineering disciplines.
