We searched lots of ventilation companies and finally made the right choice to pick BDVair. Bruce came and assessed our home, explained clearly what we needed and why. The house was a challenge under very limited roof space and on the day it was very hot. Thanks to Bruce and Gabrielle’s quick response and working under challenges, our house is now cooler and dryer at night time.
We would highly recommend BDVair and wish them all the best in the industry.”
