Trane S9B1 Furnace Review
The Trane S9B1 Furnace Review is the brand’s most affordable natural gas furnace and the lowest in its efficiency lineup. With a 92% AFUE, it offers solid performance and Trane’s renowned reliability, but it may not meet the needs—or legal requirements—of all Canadian homes due to newer efficiency standards.
This review covers everything you need to know about the S9B1, including specifications, pricing, warranty coverage, and comparisons with other Trane models to help you determine if it’s the right fit for your home.
In a Nutshell
Average Installed Price: $4,500 – $5,500
AFUE: 92.1%
Operation: Single-stage
Blower Type: Constant torque ECM
ENERGY STAR® Certified: Yes
Heating Input: 40,000 – 120,000 BTU
Top Features
Durable stainless steel primary and secondary heat exchangers
Compact design ideal for tight spaces
Compatible with Trane CleanEffects™ air purification system
Dual-fuel ready (can integrate with an electric heat pump)
Fuel-saving ignition system with silicon nitride hot surface igniter
Superior multi-port burner design for quieter operation
Insulated cabinet and blower compartment for reduced noise and heat loss
Pre-painted steel housing for lasting durability
Bottom Line
The Trane S9B1 Furnace Review is a budget-friendly, single-stage furnace best suited for smaller to mid-sized homes or single-story layouts. Operating at full capacity when on, it isn’t as quiet or as energy-efficient as Trane’s higher-end models, but it’s reliable and built with durable, long-lasting components.
Its secondary heat exchanger extracts additional heat from exhaust gases—allowing it to use the same amount of fuel while generating more warmth. Meanwhile, the constant torque ECM blower motor delivers better efficiency, quieter performance, and longer life compared to standard PSC motors.
However, Canadian buyers should note that new federal regulations require gas furnaces to have a minimum 95% AFUE. The S9B1 doesn’t meet this standard, meaning it can only be installed if manufactured before July 2019.

Efficiency & Performance
AFUE: 92.1%
Burner Type: Single-stage
Blower: Constant torque ECM
ENERGY STAR® Certified: Yes
The Trane S9B1 Furnace Review may be entry-level, but it includes features to improve comfort and reduce costs. When paired with a Trane heat pump, it supports dual-fuel operation, automatically switching between gas and electric heat for maximum efficiency.
It’s also compatible with Trane CleanEffects™, which removes up to 99.98% of airborne particles as small as 0.3 microns—great for allergy sufferers or anyone seeking improved indoor air quality.
The built-in furnace control board provides self-diagnostic data, simplifying troubleshooting during maintenance and potentially lowering repair costs over time.

Comparable Trane Models

AFUE: 97.3%
Operation: Modulating, variable-speed
Average Price (Installed): $6,400 – $7,000
The XC95m meets modern efficiency standards, adjusts output in 1% increments for precise comfort, and includes ComfortLink™ II and Comfort-R™ technologies for humidity control and seamless communication with other Trane equipment.
2. Trane S9V2-VS (Mid-Tier Upgrade)
AFUE: 97%
Operation: Two-stage
Blower: Variable-speed Vortica II
The S9V2-VS offers quieter, more efficient heating and better temperature balance throughout your home. It’s also compatible with Comfort-R™ for improved summer dehumidification.
3. Trane S9X1 (Modern Equivalent)
AFUE: 96%
Operation: Single-stage
Blower: Constant torque ECM
Nearly identical to the S9B1 but compliant with current efficiency regulations, the S9X1 delivers better long-term savings and is the most comparable current Trane model.
Final Verdict
The Trane S9B1 is a dependable, cost-effective option for homeowners who don’t require ultra-high efficiency or advanced features. While it’s no longer compliant with current Canadian efficiency standards, its solid construction, secondary heat exchanger, and ECM motor make it a worthy choice for smaller spaces—if still available through local distributors.
