Make changes to insulation and heated floor area part of the sizing conversation.

Planning furnace work in Castlegar

For a Castlegar home that has been renovated, list the improvements before requesting a replacement. New windows, added insulation or a change in the space being heated can affect the design. Ask how those changes were considered instead of relying on the output of the old furnace.

For replacement, ask for the home’s current heating requirement rather than simply matching the old furnace. Share changes to insulation, windows, floor area and occupancy. A written sizing explanation helps you compare proposals that use different equipment capacities.

  • What has changed since the existing furnace was installed?
  • How was the required heating output calculated?
  • Which duct or return-air changes are included?

Choose the right kind of request

Furnace repair

Describe the fault, whether the home has heat, and any existing diagnosis. Confirm the diagnostic charge and appointment before expecting attendance.

What a repair should include

Furnace installation

For a new system, ask how the home was sized and what duct, fuel, electrical, venting and permit work is included.

Plan a complete installation

Furnace replacement

Compare a documented repair option with replacement, then include comfort goals, cooling needs, warranties and verified rebate conditions.

Questions for your Castlegar project

The exact property and proposed equipment determine the design. Discuss access, venting, fuel supply and dependable follow-up support alongside the initial installation.

  • Provide the address and any access or delivery constraints.
  • Ask for local design conditions to be reflected in the load calculation.
  • Confirm parts support, maintenance arrangements and any backup-heat strategy.

Confirm the current permit requirements for your exact property with the relevant authority and the qualified contractor. A municipal information link is a starting point; it is not a permit approval.
