What a furnace installation should cover.

The furnace cabinet is only one part of the project. Proper replacement planning includes the home, connected ductwork and AC coil, airflow, venting, utilities, controls, access, and startup testing.

When to call

When homeowners consider furnace replacement.

Furnace sizing and airflow work together

A new furnace should match the home's heating needs and the duct system's ability to move air. Oversizing or ignoring airflow can contribute to noise, short cycling, uneven comfort, and avoidable operating problems.

Review the equipment connected to the furnace

In many homes, the central AC coil, blower, thermostat, ductwork, venting, and electrical connections interact with the furnace installation. Compatibility and condition should be checked before equipment is selected.
