Furnace Ratings

In comparing gas furnace brands, you should consider things such as their warranty, efficiency, construction features, technology used, and their price.

With our gas furnace ratings, you can compare furnace models side by side using our Head To Head tool. You can compare over 250 models from more than 60 brands in thirteen categories such as warranty, efficiency, construction, availability, & where they are made. You can also read the individual reviews of each brand below. These ratings are for ducted split system gas furnaces. Our simple rating system gives each brand a color code and a star rating. If the card is green, then, that is one of the top picks from HvacRepairGuy. If the card is yellow, then, that would be a budget pick from HvacRepairgGuy. If the card is red, then, the brand is not recommended by HvacRepairGuy. With our gas furnace reviews, you can cut through the sales hype and find value. It truly is like you were taking a repairman shopping with you!
