What Size Should My Replacement Furnace Be?02/29/2016What Size Should My Replacement Furnace Be? You’ve reached the point where it’s time for a furnace replacement or perhaps you see this point rapidly approaching, but how do you figure out the size of system you’ll need? Selecting the best size is crucial for your system’s efficiency and your home’s comfort. There’s a perfect furnace out there for you and your budget. When replacing your system, bigger isn’t always better. Buying a system that is too large wastes energy and money. A larger system will continuously be warming up and cooling down because it’s output will not require it to workas long. This is known as “short cycling” and it increases the wear on your system and in turn hurts the lifecycle of your system. An oversized unit will cost you more money up front and over time. On the other hand, a system that is too small will operate too long and won’t be able to fully heat your home when the weather gets chilly. An inadequately sized system will have to work harder, your energy expenses could be higher and your comfort will suffer because of that. It’s very important to work with a professional that will complete a load calculation and advise you on the correct system for your needs. How is Load Calculation Determined? A home’s load calculation used to be calculated based solely on square footage and was often wrong. Technology and knowledge have evolved a lot since then.
