Bryant 135SANLegacy™ Line Single-Stage

Yes, the Bryant 135SAN is designed specifically for Puron Advance® (R-454B) refrigerant. This next-generation refrigerant has 78% lower global warming potential (GWP) than R-410A, meeting upcoming environmental regulations. R-454B is classified as A2L (mildly flammable) with enhanced safety features built into the 135SAN's design. For Portland homeowners, this means your system is future-proofed against refrigerant transitions, avoiding costly conversions when older refrigerants are phased out. The 135SAN achieves 16.5 SEER2 efficiency with R-454B while maintaining single-stage reliability.

Portland's wet marine climate can be tough on outdoor HVAC equipment. The Bryant 135SAN's DuraGuard™ protection includes a louvered coil guard that shields the aluminum fin coil from physical damage while allowing proper airflow, plus a powder-coated finish on all metal surfaces to resist corrosion from rain and moisture. This is especially important in Portland where units may be exposed to coastal air, frequent rain, and high humidity. DuraGuard protection extends system life by preventing premature corrosion of the coil and cabinet, protecting your investment and maintaining efficiency over the unit's 15-20 year typical lifespan.

The Bryant 135SAN (Legacy series) and 146SAN (Preferred series) both offer 16.5 SEER2 efficiency with single-stage operation, but differ in key features. The 135SAN uses Puron Advance® (R-454B) refrigerant, while the 146SAN uses R-410A. The 146SAN includes InteliSense remote monitoring technology and quieter 67 dB operation, while the 135SAN operates at 71 dB without remote monitoring. The 135SAN focuses on reliable, straightforward single-stage cooling with future-ready refrigerant at a lower price point. For Portland homeowners who prefer the new refrigerant technology and don't need remote monitoring, the 135SAN offers excellent value.
