ENERGY STAR® Qualified
Advanced RPJ Heat Exchangers
The modulating gas valve enables the furnace to operate at varying levels rather than full power all the time. This ensures consistent indoor temperatures, quieter operation, and lower energy consumption. When additional heat is needed, the system gradually increases output in fine increments for optimal comfort.
The ION System Control is more than just a thermostat—it’s a full home comfort management system. It offers control over:
Temperature
Humidity & dehumidification
Ventilation
Indoor air quality
The ION control is Wi-Fi enabled, allowing remote adjustments from any internet-connected device. Its intuitive touchscreen and user-friendly interface make managing home comfort simple and convenient.
KeepRite provides some of the best warranties in the industry. The G9MAE includes:
No Hassle Replacement™ Limited Warranty: 10 years (replacement unit if a major component fails, as detected by the ION system).
10-Year Parts Limited Warranty
Lifetime Heat Exchanger Limited Warranty
Important: You must register your furnace within 90 days of installation to receive the full warranty coverage. Unregistered units receive reduced terms.
G9MAE vs. ProComfort Series G9MXT
The G9MXT is slightly less efficient at 96% AFUE and lacks the ION System Control. While it remains a strong performer, the G9MAE offers higher energy efficiency and smarter home integration—ideal for homeowners seeking top-tier performance.
G9MAE vs. ProComfort Deluxe Series G9MVE
Both models share similar technology, but differ in their control systems:
G9MAE: ION System Control (modern touchscreen, “Touch-N-Go” quick settings).
G9MVE: Observer Communicating Wall Control (simple 4-wire installation).
Both are Wi-Fi enabled with intelligent diagnostics, so the choice depends on personal preference for design and interface.
G9MAE vs. Performance Series N9MSB
The N9MSB is an entry-level model with 92.1% AFUE, making it less efficient and feature-rich. It lacks modulating gas valves and advanced controls. While it’s more affordable upfront, the G9MAE delivers far greater long-term energy savings and comfort.
