Carrier Infinity 98 with Greenspeed 59MN7
The main comparison is modulation versus the two-stage Infinity alternatives. Ask the contractor what heating-demand pattern justifies the additional control range in this home. A higher tier should solve an identified comfort requirement, not merely occupy the top row of a brochure.

Exact cabinet drawing was not verified for this profile. Use the manufacturer sources below and request the selected model’s current dimensional sheet before ordering.
What distinguishes this family
Ask for the minimum as well as maximum delivered heat of the selected configuration. A modulating furnace can still be poorly matched if its minimum usable output exceeds the load for long periods. Have the installer explain the chosen size in relation to the written heat-loss result rather than choosing the largest cabinet available.
The control and installation decision
Before paying for Greenspeed-related functions, identify the required Infinity control and every retained outdoor component. Request a written account of which functions will be available immediately and which would require a future equipment change.
Size and evidence to obtain
For the 59MN7, 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 59MN7 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.
