Recommendations & Guidance

Recommendations

  • Always complete an air seal verification at Rough – to ensure a successful blower door test result at final

 

Basic Guidance

Preparing Site for Duct Blaster Testing:  Please ensure that the following steps have been completed before our scheduled site visit:

  • Install all ducts and air handlers
  • Inspect for missing / disconnected ducts
  • Seal floor supply covers to subfloor with tape or mastic

Preparing Site for Blower Door Testing:  Please ensure that the following steps have been completed before our scheduled site visit:

  • Ensure that all caulking and sealing of interior trim, lighting, and exhaust fans (to drywall) has been completed.

 

Other Good Practices that we Recommend

Design

  • ACCA Manual J, D, and S review -   to verify that HVAC ducts and equipment are properly designed, and sized.

Rough

  • Exhaust duct size and installation quality verification - to ensure that exhaust fans will perform to the design specifications (ASHRAE Standard 62.2).
  • HVAC supply and return duct sizing verification – to minimize the risk of hot and cold rooms

Final

  • Exhaust air flow testing - to ensure that exhaust fans will perform to the design specifications (ASHRAE Standard 62.2).
  • Supply air flow testing – to minimize the risk of hot and cold rooms.
  • Static pressure testing – to verify that HVAC system is operating efficiently.
  • Room air balance testing -  to verify that each bedroom has sufficient supply and return air flow.
