Bryant Evolution 98 modulating 987M
The 987M is the modulating Evolution family. Its Canadian page advertises up to 98.5% AFUE, while the current downloaded Canadian-market certification rows located for its prefix topped out at 98.3%. Treat this as a configuration-verification question rather than substituting either number indiscriminately.

What distinguishes this family
The appropriate comparison is the complete 987M system against a sized two-stage Evolution alternative. Ask whether the added modulation will address a measured comfort issue and obtain the minimum and maximum output of the proposed suffix. A family capacity range does not answer either question.
The control and installation decision
Have the dealer identify the supplied Evolution control and confirm which advertised features require it. Where data sharing or remote service is discussed, ask for consent settings and a description of the normal offline heating operation.
Size and evidence to obtain
For the 987M, 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 987M 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.
