What Size Should My Replacement Furnace Be?02/29/2016What Size Should My Replacement Furnace Be? You’ve come to the point where it’s time for a furnace replacement or perhaps you see this point approaching quickly, but how do you figure out the size of system you’ll need? Picking 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 home’s needs. When replacing your system, bigger isn’t always better. Installing a system that is too large wastes energy and money. A larger system will continuously be warming up and cooling down because it’s production will not require it to runas long. This is known as “short cycling” and it increases the wear on your system and in turn decreases the life of your system. An oversized furnace will cost you more money up front and in the long run. On the other hand, a system that is too small will run too long and won’t be able to fully heat your home when the weather gets frigid. An improperly sized system will have to work harder, your energy costs may be higher and your comfort will be impacted because of that. It’s very important to speak with a pro that will do a load calculation and advise you on the best 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 made a lot of advances since then.

Load calculations are made of everything from the construction of your home, amount of insulation, the local climate in addition to type and color of your roof, to the number of home occupants – a truly comprehensive assessment of your needs.
