Carrier Infinity 97 59TN7
The 59TN7 illustrates why a comparison needs source notes. The manufacturer headline says up to 97.0% AFUE while one technical field on the reviewed page still says 96.7%. Use the current sheet and certificate for the quoted full model to settle the number.

What distinguishes this family
Compare this Infinity two-stage option with the 59TP7 on actual blower and control functions. An efficiency number alone does not capture that distinction. Ask the installer which comfort features require an Infinity control, whether it is included, and what the fallback operating arrangement is if a connected feature is unavailable.
The control and installation decision
Do not pay a large premium simply because one family label ends in 97. Require the incremental installed cost to be tied to a particular feature or documented rating. A salesperson can explain the difference without making unsupported predictions about years of service.
Size and evidence to obtain
For the 59TN7, request the rated input, rated output and cabinet dimensions from the exact product-data row. The complete suffix matters. Keep a photograph of the existing installation and a proposed layout with the written appraisal. A postal code supplies local context for that review, but it cannot identify the house’s heat loss, duct capacity or concealed installation conditions.
Cost and reliability judgement
The 59TN7 does not have a verified nationwide installed CAD price in this guide. Ask for a local itemized quote and compare equivalent work. Likewise, no controlled Canadian failure-rate ranking was found for this family. Review parts support, labour terms and commissioning evidence. When an otherwise comparable price remains substantially different without a clear written reason, obtain a second independent appraisal.
Cost, reliability & alternatives
No verified current national installed CAD price schedule was found. Compare an itemized local proposal for the exact model, controls, installation work, tax treatment and labour coverage. A large unexplained gap deserves an independent second opinion after scope is normalized.
No defensible comparative Canadian failure-rate ranking established.
