What Size Should My Replacement Furnace Be?02/29/2016 What Size Should My Replacement Furnace Be? If you’re looking for a replacement furnace or will be soon, the first step is to identify what size of system will work properly for your home. Having a correctly sized system is important to its efficiency and the comfort level of your home. With a bit of research, you’ll find the perfect furnace for your needs. When replacing your system, bigger isn’t always the best. You will waste a lot of energy and money if you install a system that is larger than necessary. A system that is too large won’t have to run as long, so it’ll be frequently cycling on and off, which means extra wear on your system and can reduce the life of your system. An oversized system will not only cost more money up front, but it will cost you more over time as well. This is a decision you’ll want to dodge. Then there are the challenges with a system that is smaller than necessary. If your system is too small, it will run more frequently to try to heat your house, and it won’t be able to get the job done despite its exertion. A system that is too small will work harder, which will shorten the system’s life span. Plus, you’ll be paying higher utility bills for a home that’s not adequately heated.
