In order to help homeowners shop for furnaces and air conditioners, we developed our own proprietary algorithms which weigh a range of criteria and factors to provide an easy-to-compare grade (e.g. B-, A+, etc).
Warranty Grade: It can be difficult to know which brands and models offer the best warranty coverage, particularly because a lot of the key details are hidden in dense warranty documents filled with hard to understand legalese. Thankfully for you, we’ve carefully studied them and created this grading system to account for things like the length AND quality of their guarantee, coverage restrictions and more!
Overall Grade: This grade weighs key factors like efficiency, ENERGY STAR certification, comfort, noise level (for A/Cs), our warranty grade, and more.

Comparable models by Tempstar
Model Comparison by middle-tier – Tempstar N9MSB versus Tempstar N9MSE
The N9MSB and the N9MSE are very similar furnaces. Almost identical in terms of features, the big difference comes when you consider their respective AFUE ratings. The AFUE rating shows how efficient your furnace is, with the respective percentage being equivalent to how many cents in every dollar actually goes towards heating your home. The N9MSB has an AFUE rating of 92%, whereas the N9MSE has a rating of 95%. This means that the N9MSB will cost less up-front but cost more in terms of wasted energy over time. For many, it may be worth a little extra outlay at purchase to have the more efficient N9MSE.
Model Comparison by features – Tempstar N9MSB versus Tempstar F9MAE
If you’re looking to upgrade on features, the F9MAE includes Tempstar’s latest technology. For example, the F9MAE comes equipped with the WI-FI enabled Ion System Control, a sophisticated control centre for your furnace that you can access from any compatible device that’s internet enabled! It also features a modulating operation as opposed to the N9MSB’s single-stage operation, which means that it can operate at a lower stage to save energy but when needed, can smoothly increase the heat in-line with any temperature drops!
Model Comparison by premium tier – Tempstar N9MSB versus Tempstar F9MVE
The Tempstar F9MVE is one of Tempstar’s premium furnace offerings. It beats the N9MSB’s AFUE rating sitting at 96.5% and has a host of other features. For example, the F9MVE features a two-stage gas valve as opposed to the N9MSB’s single-stage operation. Put simply, this means that the F9MVE can operate in low fire and high fire modes instead of one heating mode when the thermostat kicks in. This eliminates unwanted temperature swings in your home, ensures a more even heating across your home and helps keep energy costs down even further.
