We provide residential mechanical design services for heating, cooling and ventilation. A properly sized designed system helps mechanical contractors, builders and home owners improve comfort, efficiency, durability of equipment and improves air quality.
Our HVAC designs provide the proper documents for building permit applications, covering Sections 9.32, 9.33 and 9.36 of the National Building Code.
Why is it important to have a properly sized HVAC design from a certified design expert?
Maximum efficiency of the HVAC system.
Proper distribution of heating or cooling at all times of the year alleviating the problem of rooms that are too hot or too cold.
Heat loss calculations
Heat Loss/Heat Gain Calculations
Block load heat loss/heat gain calculations for new and replacement equipment provides proper equipment sizing for heating and air conditioning systems as required in section 184.108.40.206.1 of the National Building Code. This allows for proper sizing of the furnace and air conditioner units. When this equipment is sized properly, the house is more comfortable for the occupants and more efficient, resulting in less energy usage and lower utility costs.
Room by Room Calculations
Room by room heat loss/heat gain calculations for design of distribution systems is required in section 220.127.116.11.1 of the National Building Code. Going into this level of detail ensures comfort levels are even throughout the entire home. It ensures the proper amount of warm or cool air is supplied to each room, allowing for consistent temperatures and comfort levels regardless of where you are in the home.
Duct Design for forced air heating and cooling systems as set out in Section 18.104.22.168.1 of the National Building Code. We use the HRAI Digest method. Duct design ensures the proper amount of air actually reaches each part of the home as calculated in the room by room calculations. Regardless of where you are in the home, temperature and comfort levels are maintained.
Mechanical Ventilation Design
Mechanical Ventilation Design is required by Section 9.32 of the National Building Code. This provides the removal of stale air from the home and replaces it with an equal amount of fresh air to ensure a healthy environment for the homes occupants.
