Feedback from completed installation projects.

— I. Constantinou, homeowner
Home office recording setup needed a quiet system, and they specifically sized and placed equipment to keep noise down in that room.
— U. Nnamdi, remote worker
Multi-generational household with very different temperature preferences upstairs versus down. Proper zoning during install solved an argument that had been going on for years.
— E. Malinowski, homeowner
Basement apartment conversion needed its own independent system separate from the main house, and they designed the whole thing around that specific requirement instead of trying to tie into the existing ductwork.
— F. Castellucci, homeowner
