HOMEOWNER FAQS
Frequently asked questions
Can a new furnace use the existing ductwork?
Sometimes, but the contractor should verify that supply and return ducts can handle the required airflow without excessive noise or pressure.

Startup should confirm airflow, temperature rise, fuel or electrical operation, venting, safety controls, thermostat function, and manufacturer requirements.
