Ductwork gets evaluated as part of the install, since a new system on old, undersized ducts underperforms.
Written estimates cover equipment, labor, and any necessary duct modifications together.
If you're dealing with an old system finally beyond economical repair, a home addition that needs its own conditioned zone, or a builder-grade unit that's never kept up with the house, you already know an oversized or undersized system installed without a real load calculation will short-cycle, run inefficiently, or never keep the house comfortable — for its entire lifespan.
