AFUE: Up to 97% ENERGY STAR ®: Yes Burner Type: Dual-Stage Blower Type: Multi Speed ECM Motor Price: $4,500 to $5,500 BTU Output: 60,000 to 120,000 Best For: Homeowners wanting premium comfort without ultra-premium pricing
Most homeowners researching the KeepRite G97CTN review never realize how uneven their heating is until they use a modulating-style comfort furnace.
Many older furnaces operate with aggressive ON/OFF heating cycles that create temperature swings, loud airflow, dry winter air, and rooms that never feel consistently comfortable.
The KeepRite Ion™ G97CTN was built for homeowners who want noticeably smoother comfort and quieter heating without paying luxury-tier furnace pricing.
That is what makes this furnace stand out in the KeepRite lineup.
Instead of focusing only on AFUE numbers, the KeepRite G97CTN review conversation is really about overall comfort quality:
steadier temperatures
quieter airflow
improved efficiency
better humidity balance
more controlled heating cycles
For many homeowners, those upgrades become more noticeable than efficiency ratings alone during long Canadian winters.
Limited Inventory Notice: The KeepRite Ion™ G97CTN has been marked by the manufacturer as having limited inventory availability. However, select distributors and HVAC contractors may still have remaining stock available for installation.

What Makes the KeepRite G97CTN Different?
Most budget furnaces heat homes in large bursts.
The G97CTN works differently.
Its dual-stage gas valve and variable-speed ECM blower adjust heating performance based on actual comfort demand rather than operating at maximum output all the time.
That creates:
quieter heating cycles
smoother airflow
more balanced room temperatures
fewer hot and cold spots
less temperature fluctuation
This is one reason many homeowners upgrading from older single-stage furnaces immediately notice the comfort difference.
What Does Two-Stage Heating Actually Feel Like?
This is one of the most important things homeowners researching the KeepRite G97CTN review want to understand.
A standard furnace typically feels like:
full heat → OFF → full heat → OFF
A two-stage furnace like the G97CTN behaves more gradually.
Most of the time, it runs at lower heating capacity to maintain stable temperatures efficiently. When outdoor temperatures drop significantly, the furnace automatically increases output to maintain comfort.
The result is:
more even warmth
quieter operation
reduced airflow noise
improved overnight comfort
less overheating near vents
For many homeowners, this creates a “premium comfort” feeling without stepping into ultra-high-end modulating furnace pricing.
⚙️ Performance and Efficiency
With an AFUE rating of up to 97%, the KeepRite G97CTN converts nearly all consumed fuel into usable heat.
That means lower wasted energy and reduced heating costs during winter.
The combination of:
dual-stage heating
variable-speed airflow
intelligent system controls
helps the furnace maintain stable indoor comfort while improving operating efficiency.
The variable-speed ECM motor also improves airflow consistency compared to older PSC blower motors commonly found in aging furnaces.
🌟 Key Features
Variable-Speed ECM Motor
The ECM blower continuously adjusts airflow to improve:
comfort consistency
humidity control
quiet performance
energy efficiency
Compared to older fixed-speed motors, airflow feels smoother and less aggressive.
Dual-Stage Heating
The furnace operates at lower heating output most of the time to reduce cycling and improve efficiency.
When additional heat is required during colder weather, the system automatically increases capacity.
Quiet Operation
The insulated cabinet and soft-mounted blower system help reduce vibration and operational noise.
This is one reason homeowners comparing:
KeepRite QuietComfort® 97 G97VTN Review
KeepRite QuietComfort 96 G96VTN Review
often also consider the G97CTN.
Smart Wi-Fi® Control
When paired with the Ion™ Black System Control, homeowners can:
monitor system performance
adjust temperature remotely
improve scheduling efficiency
receive intelligent diagnostics
Dual Fuel Capability
The G97CTN can integrate with compatible heat pump systems for improved efficiency during changing seasonal temperatures.
This setup can help reduce gas usage during milder weather conditions.
💡 Benefits of the KeepRite G97CTN
Premium Comfort Without Luxury Pricing
The G97CTN targets homeowners who want advanced comfort features without paying the extreme pricing associated with some ultra-premium communicating systems.
Better Temperature Consistency
The variable-speed airflow and two-stage heating help reduce:
hot and cold spots
temperature swings
harsh heating cycles
Lower Operating Costs
Higher efficiency means less wasted fuel and lower long-term winter heating expenses.
This becomes especially important in colder Canadian climates with long heating seasons.
Improved Indoor Air Quality Compatibility
The system works with:
humidifiers
advanced filtration systems
air purifiers
allowing homeowners to improve overall indoor comfort beyond heating alone.
