What to Expect During Furnace Installation in Coeur d'Alene

A furnace installation is a full-day project for most Kootenai County homes. Here is the complete sequence.

Pre-Install Assessment

Before installation day, a technician assesses the site: gas line size and connection point, venting configuration, electrical supply, and space access. This eliminates day-of surprises and confirms whether any additional work is needed.

Installation

Day

Equipment arrival and staging. New unit arrives with technicians. Most residential units require two people to move to the installation location.

Old unit shutdown. Gas shut off at the supply valve. Electrical disconnect opened. The old furnace is disconnected from gas, electrical, venting, and ductwork -- then removed.

New unit placement. Positioned, leveled, and secured. Ductwork supply and return connections made.

Gas connection. Gas line connected and pressure-tested for leaks before any ignition. No exceptions.

Venting. Standard 80% units connect to existing flue or B-vent. High-efficiency condensing units run new PVC exhaust and intake through an exterior wall, plus condensate drain.

Electrical. Control wiring to thermostat. 120V power at disconnect.

Startup and testing. Full test sequence: ignition, flame sensor, heat exchanger check, blower motor, thermostat communication, safety switches. CO levels checked at registers. Airflow verified across all zones.

Walkthrough. Filter location, emergency shutoff, error code reference, warranty details.

What Takes Longer

Crawl space access. High-efficiency venting conversion. Gas line upsizing. Ductwork modification.
