If you’re currently looking for a new heating system, you might be more than a little overwhelmed by the choices you have available. Amid the sea of different models, fuel types, and other configurations, it can be all too easy to gloss over things that should really not be ignored. One of those things is efficiency ratings. Before you settle on a new heating system, whether it’s a furnace or a heat pump, you need to know the efficiency ratings and what they mean. Otherwise, you may find yourself with a system that doesn’t meet your heating needs properly.
