The Base 80 gas furnace features 80% Annualized Fuel Utilization Efficiency (AFUE) and because of its small size, it can fit in the tightest of installations.
This is Harker’s expert opinion on the product as a whole. Intangibles such as durability, ease of repair/install, and value are taken into consideration. We want to make it clear that we do not offer any bad products. Not every product can be used in every situation, so sometimes a 3-star product will be a better fit than a 5-star. All star ratings are pure opinion.
