Include additions and changes in space use
For Vineyard heating and cooling projects, describe rooms added or repurposed since the equipment was installed. The important question is whether the present system and duct arrangement suit the current building.
For replacement, ask whether the proposal includes room-level load review, duct corrections and the controls needed for the selected equipment. For repair, keep the original symptom separate from optional improvements so authorization is clear.
For packaged units, bring changed floor plans and scope clarity into the scope discussion. Compare the existing fuel arrangement with suitable replacement choices. If a heat-pump conversion is considered, evaluate electrical requirements and the approved equipment configuration before relying on a rebate.
