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.
