Bryant 935SALegacy™ 95 Ultra-Low NOx Gas Furnace

The 935SA is unique because it combines 95% AFUE high efficiency with California Air Resources Board Ultra-Low NOx certification. Most 95% furnaces prioritize efficiency alone, but the 935SA uses advanced burner technology to achieve both high efficiency AND 85% lower nitrogen oxide emissions. This makes it ideal for Portland homeowners who want maximum gas savings without compromising air quality. While other 95% Legacy models like the 916S offer similar efficiency, only the 935SA provides Ultra-Low NOx certification for California compliance and cleaner combustion.

Yes, as a condensing furnace, the 935SA requires PVC venting and a condensate drain - different from 80% furnaces that use metal B-vent chimneys. The 935SA extracts so much heat that exhaust gases cool below the dew point, creating water condensation that must be drained. This means your installer will run PVC piping for exhaust (not metal flue) and install a condensate pump or drain line. While installation is more complex than non-condensing 80% models, the 95% efficiency and Ultra-Low NOx emissions make it worthwhile for environmentally-conscious Portland homeowners.

The 935SA occupies a unique position in Bryant's lineup: it's the only Legacy series furnace offering both 95% AFUE efficiency and Ultra-Low NOx certification. The 830SA offers Ultra-Low NOx at 80% AFUE, while the 916S offers 97% AFUE without Ultra-Low NOx certification. If you want BOTH high efficiency (95%) AND cleanest emissions, the 935SA is your Legacy series choice. For even higher efficiency with Ultra-Low NOx, you'd need to step up to Preferred or Evolution series models, which cost significantly more.
