Bigger is not automatically better
Oversized equipment can create comfort and humidity problems. A contractor should explain sizing using home characteristics, not only square footage.
What to ask
Ask whether the contractor performed or estimated a load calculation, checked duct capacity, and considered insulation, windows, ceiling height, and climate.
These ranges are educational estimates only. Final contractor pricing depends on your home, system, equipment, local labor, permits, and project details.
