Furnace Installation & Replacement

High-efficiency furnace replacement, sized for the home

About Furnace Installation

A new furnace should be sized using a load calculation rather than matched to the old unit. Efficiency is measured by AFUE — the percentage of fuel converted to usable heat. High-efficiency condensing furnaces typically require different venting and a condensate drain, which affects installation.

Typical Furnace Installation Process

1
Home Assessment
The home, ductwork and venting are evaluated and a load calculation is performed.
2
System Selection
Options are compared by capacity, AFUE efficiency and features such as variable-speed blowers.
3
Installation Day
The old furnace is removed and the new one installed with any required venting changes.
4
Testing & Commissioning
Gas pressure, combustion, temperature rise and safety controls are verified.
5
Walk-Through
The homeowner is shown filter location, thermostat operation and maintenance needs.

Frequently Asked Questions

Consider replacement if the furnace is approaching the end of its typical lifespan, needs frequent repairs, or heating bills are rising. A cracked heat exchanger is a safety concern that usually means replacement.
