Serving HVAC contractors, architects, builders, and homeowners in Ontario.
Company Focus
We design Heating, Ventilation, and Air-conditioning designs for Residential and Commercial buildings. Residential Design Protocol is F280-12. Commercial Design Protocol is Ashrae CLTD or RTS method for Commercial buildings. In all cases HRAI™ protocol is used.
Services & Rates
HVAC Installers - I work closely with installers to ensure the proper design protocols are used and that a design is correct for the building.
Value Added HVAC Design
- We work with the architect, contractor and installer to design an HVAC system that is successful. We interact with the various building inspectors and modify our designs to meet individual needs of each Building Department. This activity is included in the design price.
- Turnaround time can be a critical item in getting a building permit. I can deliver HVAC Designs in less than a week and sometimes overnight if the need is great and the design not too complex.
