Harry was very thorough.  I would say a perfectionist with his programming and presentation of this to us.
The presentation of the system was very easy to follow. This proved invaluable as there were no major issues
after moving in. Harry addressed all our concerns and answered requests promptly.

Appointing the right technology consultant such as Harry and his team at Control Freq is just as important as choosing
the right Architect, Builder, Electrician and Plumber.
