Comparable Models by KeepRite

1. Lower Price Comparison: G9MVE vs. N9MSB

The N9MSB offers a more affordable upfront cost but sacrifices efficiency and features. With a 92.1% AFUE rating, it wastes about 3–4% more energy per dollar compared to the G9MVE. It also lacks smart controls like the Observer Wall Control.

  • Choose N9MSB: if you want a simple, budget-friendly furnace.

  • Choose G9MVE: if you value higher efficiency and modern features.


2. Feature Comparison: G9MVE vs. G9MXE

Both the G9MVE and G9MXE have similar efficiency levels (95–96%), but differ in functionality.

  • The G9MVE includes Wi-Fi connectivity and the Observer Communicating Wall Control for advanced remote operation and diagnostics.

  • The G9MXE, while efficient, comes with a more basic thermostat that handles only heat/cool and humidity functions.
    If you want smart home integration, the G9MVE is the clear winner.


3. Premium Tier Comparison: G9MVE vs. G9MAE

Both furnaces are part of KeepRite’s Deluxe Series, but the G9MAE takes efficiency and comfort to the next level.

  • G9MAE: Features a variable-speed blower and modulating gas valve, allowing it to fine-tune heating output from 35% to 100% capacity for ultra-consistent comfort.

  • Efficiency: 97–98% AFUE (compared to 95–96% for the G9MVE).
    If you want the quietest, most precise, and energy-efficient heating experience, the G9MAE is the superior—though pricier—option.
