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.

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, which is exactly why hvac installation calls in Ellisville, MO get treated with urgency, not a next-available-Tuesday slot.
