Sure Comfort S962V
S962V is the Canadian Vantix two-stage option with constant-CFM airflow and EcoNet-related features. It should be distinguished from the older S96T constant-torque family. Similar efficiency labels can conceal a meaningful difference in blower control and the controls package being sold.

Manufacturer pictures & technical drawings
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.
Capacity and installation fit
Ask for the exact full-model submittal and the selected input and heating output. Four-way multi-position capability does not establish which orientation will be used at the property. The quote should show the furnace, filter, connected coil if present and the service space that remains after installation.
Compare the proposal, not just the badge
The upgrade comparison should identify the thermostat and commissioning included with S962V. A proposal may say EcoNet enabled without including every remote or communicating function. Require a current Canadian warranty certificate and a separate labour commitment; neither is a substitute for evidence about comparative failure rates.
Evidence to request before purchase
For the S962V, keep the complete suffix and the dated specification with the quotation. Have the installer identify the selected heating output, installation orientation and control arrangement in writing. A family maximum is not necessarily the rating of the unit supplied. Ask for the completed startup record and the current Canadian warranty certificate, including labour exclusions. This profile does not assign a failure-rate score or convert a warranty promise into evidence of longer life.
Cost, reliability & alternatives
No current Canadian installed-price schedule from the manufacturer was verified. Seek itemized quotes for the exact Vantix family, including the selected controls and local support arrangement.
The Canadian pages provide equipment features and warranties, but not comparable Canadian field-failure rates. No reliability ranking against related Paloma Rheem brands is justified from those materials alone.
