A large share of comfort complaints in existing Berkeley homes trace back to sizing at installation, not a failing part. Assessment comes before equipment selection, every time.

We don't skip the parts that would cause problems at resale.
Two separate warranties, both in writing, both real.

Historic home with plaster walls that make duct modifications tricky. They found routes through existing chases instead of cutting into walls we wanted to preserve.
— 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
What people usually ask before installing.
Whoever installed the original system may well have guessed wrong on size, and copying that number just carries the error into the new equipment.
Most residential installs finish in one to two days depending on ductwork.
We take care of pulling and filing the paperwork ourselves so it's not one more thing on your plate.
A workmanship warranty backs the install.
Undersized ductwork gets caught during the assessment and corrected before the new system ever gets connected to it.
