Concord 97G2EK
A Concord quote should name the actual branded unit and distributor even when another bidder offers an Allied sister brand. This is the two-stage option to examine when the buyer wants a simpler blower package while retaining staged combustion. The reviewed technical table includes a 30,000 BTU/h high-fire upflow/horizontal size, which makes the complete model choice more informative than a broad good-better-best label. Compare first-stage output, thermostat control and the proposed duct measurements. A technician should explain why the selected size is necessary rather than automatically match the old furnace input. Keep substitution approval separate from the initial price acceptance.

What makes 97G2EK worth comparing
A Concord quote should name the actual branded unit and distributor even when another bidder offers an Allied sister brand. This is the two-stage option to examine when the buyer wants a simpler blower package while retaining staged combustion. The reviewed technical table includes a 30,000 BTU/h high-fire upflow/horizontal size, which makes the complete model choice more informative than a broad good-better-best label. Compare first-stage output, thermostat control and the proposed duct measurements. A technician should explain why the selected size is necessary rather than automatically match the old furnace input. Keep substitution approval separate from the initial price acceptance.
Capacity and physical fit
30,000–110,000 BTU/h high-fire input in reviewed upflow/horizontal variants. 29,000–108,000 BTU/h high-fire output in reviewed upflow/horizontal variants. 33 in cabinet height; model-specific widths and drawing dimensions must be checked in the linked specification sheet.
Review the proposed installation
Use a same-scope comparison for 97G2EK: separate equipment, labour, vent route, condensate work, thermostat, filter cabinet, disposal and tax. Mark unresolved items as unknown instead of assigning them a zero cost. A remote assessment using postal context and photographs can help organize questions, but it cannot establish hidden site conditions or a fair maximum price. If a substantial price gap remains after the differences are explained, obtain an independent written second opinion.
The question that resolves the choice
The specific question to put to the installer is: Why was this exact size selected instead of the next smaller or larger documented option? Ask for the answer in writing, linked to the quoted 97G2EK model and the work included. If the explanation changes after the visit, retain both versions and identify the newly observed condition. This gives a second reviewer useful evidence and avoids comparing an early allowance with a final assessed price as though they were the same promise.
Read the efficiency number in context
The published 97% figure for 97G2EK is a family comparison point. Ask for the selected model’s own rating and keep that record with the proposal. It does not include every household energy expense, determine the price of fuel or establish the condition of the ducts. An operating-cost estimate should disclose its fuel-price and usage assumptions so a reviewer can reproduce the calculation rather than accept an unexplained saving.
Cost, reliability & alternatives
No universal Canadian installed price is asserted. Obtain dated CAD equipment and installed-scope amounts, tax treatment and local assessment; compare like-for-like written proposals.
No defensible comparative Canadian failure-rate ranking established.
