Is $4,000 to add a separate hvac zone for a bonus room above the garage a fair price?

Project Details

We are building a house and will be finishing the bonus room above the garage to use as an office. The room has four outside surfaces including the floor over a cold garage and the roof above, which makes its heating and cooling needs more extreme than a standard bedroom.

Quote Details

Installation of a dedicated HVAC zone for the bonus room to ensure independent temperature control from the rest of the upstairs. - Create a separate zone for the bonus room and office space - Install necessary ductwork and dampers to isolate the zone - Provide independent thermostat control to handle the unique thermal load of the room
