Crew was prompt and courteous. Haphazard identification of air inflow, although I pointed out some concerns following an infrared study I had done. Had to complete insulation myself, even tho' concerns were pointed out and access was easy. Quoted airflow readings differed from their device display. Final airflow percent reduction was calculated incorrectly. Remember that windows, doors, panels, fireplaces and aircon / HRV may all affect starting and ending airflow measurements, and hence what you pay.
