HRAI’s 3-day Residential Mechanical Ventilation Installation certification training program is designed for Contractors, Installers and other Building Professionals currently involved with designing and installing mechanical ventilation systems for the residential sector. Based on Canadian Building Codes and the CSA F-326 Standard “Residential Mechanical Ventilation Requirements”, this course, which includes the 300 page HRAI Residential Mechanical Ventilation Manual, covers the installation and commissioning of all types of mechanical ventilation systems with or without heat/energy recovery, house as a system principles and basic ventilation system design. Graduates of this course will be eligible to attend the Residential Mechanical Ventilation Design –Level II Course.
Detailed information on:
- Mechanical System interaction
- Ventilation capacity
- Ventilation air distribution
- Exhaust-type systems
- Balanced systems
- HRV and ERV systems
And an overview of:
- System design and layout
- Duct layout and sizing
- Grille and diffuser sizing
- Control system selection
- Combustion appliances
- Depressurization testing
- Air flow measurement
- System start-up
This 3-day course is based on the National Building Code and the CSA F-326 Ventilation Standards. The curriculum expands on the design material that is contained in the Residential Mechanical Ventilation Installation Course, and covers detailed design methods for depressurization prediction (design), depressurization testing, duct design (ventilation systems), and outdoor air connections to forced warm air systems. Learn how to design R-2000 Ventilation Systems, Systems for Baseboard Heated Houses, Systems for Forced Warm Air Houses, Exhaust Only Systems, NBC "Code Minimum" Systems, and Systems for houses with "spillage susceptible" combustion appliances. The Residential Mechanical Ventilation Installation course is a prerequisite for this course.
This course is designed for contractors and building professionals interested in developing opportunities in the growing residential ventilation market, in addition to those currently involved with designing and installing residential mechanical ventilation systems, including energy recovery ventilators. The course covers the fundamentals of air quality assessment, system requirements, and focuses specifically on system design and installation. Course participants receive the complete HRAI Residential Mechanical Ventilation Manual, as endorsed by the Home Ventilating Institute (HVI). Those who achieve 75% or higher on the exam will obtain HRAI certification. This course qualifies for 16 hours of continuing education credits towards NATE recertification, and is "BPI-Recognized" training and qualifies for 16 hours of continuing education hours for individuals certified as a BPI Heating Specialist.

This 4-day course is based on the new CSA F-280-12 "Determining the Required Capacity of Residential Space Heating and Cooling Appliances" nationally recognized standard which is referenced by all Canadian Building Codes. The course covers basic principles of heat transfer as an introduction to calculate the heat loss and heat gain in building envelopes. These principles are applied to the study of above grade heat loss and heat gain and to below grade heat loss from foundations. The course also incorporates heat loss and heat gain due to air leakage and ventilation. Internal heat gains such as people and plug loads are also included while window shade analysis rounds out the process in performing the overall heat loss and gain calculation methodology. Linked to the new standard are two Microsoft Excel® spreadsheets which are required in order to obtain necessary envelope air leakage rates and foundation loads. Please note: these spreadsheets will be covered within the course but will not be provided to each participant. They are available for purchase through CSA as part of the Standard.
This revised 4-day course builds on the knowledge and skills acquired in the Residential Heat Loss & Heat Gain course. The updated curriculum covers the proper design of residential air distribution systems in the following topic areas: layout and design of duct systems, sizing of supply and return air ducts including the proper selection of supply and return registers and grilles, C.F.M. calculations, external static pressure, and sheet metal fittings. Improvements to the course include updated equipment specifications and worksheets that reflect a modified design procedure. New examples using many types of equipment provide participants with real world installation options.
This course will be invaluable to persons installing and designing new or modifying existing air distribution systems in residential buildings. HRAI recommends that individuals interested in attending this course have prior knowledge of Residential Heat Loss & Heat Gain Calculations.
This 2-day course will take the student through the basic theory, design selection, installation and commissioning of Integrated Combination Systems, which use domestic hot water heaters in conjunction with pre-packaged air handlers for residential space heating and potable hot water. HRAI recommends that individuals interested in attending this course have prior knowledge of residential Heat Loss & Heat Gain and Air System Design.
This 2-day course will instruct participants on the proper commissioning (start-up) of residential HVAC air and water systems. The course will cover the following topics: flows and pressures within a forced air or hydronic system, ventilation system commissioning and house depressurization. This course will be invaluable to those installing, servicing and commissioning new or existing residential mechanical systems. HRAI strongly recommends that individuals interested in attending this course have prior training in residential Mechanical Ventilation, Heat Loss & Heat Gain and Air System Design.
This 4-day certification program shows how to design basic residential radiant hydronic heating systems. It includes: converting heating load calculations into water flow rates and fluid temperatures, pipe sizes, flow velocities, head losses, surface temperatures, floor coverings, tube spacing and controls. Equipment selection includes boilers, circulators, valves, air separators and expansion tanks. This course will be invaluable to persons installing and designing new or modifying existing hot water radiant heating systems in residential buildings. HRAI strongly recommends individuals attending this course have prior knowledge of residential Heat Loss & Heat Gain Calculations and experience in calculating friction losses in ducts or pipes.
This 2-day program explores the numerous elements which influence IAQ in residential buildings and will introduce participants to the terms of Indoor Environmental Quality (IEQ) and its effects on health and wellness. The Prevention, Correction and Avoidance (PCA) approach to IAQ is detailed through instruction on the building sciences for cold climates including various options in HVAC equipment and systems. The program reviews the ASTM Standard D-7297-06, Standard Practice for Evaluating Residential Indoor Air Quality Concerns including a look at various instruments and instrumentation used by investigators.
Successful participants receive a wall certificate recognizing them as "qualified" by HRAI and will be asked to sign an Agreement that details their obligations under the Qualification Program. This course is not termed a Certification Program and is not included in the SkillTech Certification Wallet Card.
