Larger square footage also means multi-zone systems, longer duct runs, and AC or furnace equipment that has to be sized correctly to reach every room evenly — not a job for a generic, one-size-fits-all approach. A contractor who understands the scale of homes in this neighborhood, and the comfort expectations that come with them, makes a real difference.
