What Size Should My Replacement Furnace Be? Posted February 29, 2016 What Size Should My Replacement Furnace Be? You’ve found yourself the point where it’s time for a furnace replacement or perhaps you see this point on the horizon, but how do you decide the size of system you’ll need? Choosing the correct size is critical 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. Buying a system that is too large wastes energy and money. A larger system will always be warming up and cooling down because it’s production will not require it to workas 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 down the road. On the other hand, a system that is too small will stay on too long and can’t fully heat your home when the weather gets frigid. An improperly sized system will have to work harder, your energy expenses may be higher and your comfort will be affected because of that. It’s very important to work with a professional that will perform a load calculation and advise you on the right system for your needs. How is Load Calculation Determined? A home’s load calculation used to be decided based exclusively on square footage and was often incorrect. Technology and knowledge have come a long way since then. When you’re ready for a replacement furnace, one of the professionals from Knoechel Heating Company will study your home as a whole and then be able to provide an accurate load calculation. Load calculations include everything from the construction of your home, amount of insulation, the local climate as well as type and color of your roof, to the number of home occupants – a truly comprehensive assessment of your needs. A properly sized and functioning HVAC system will not only keep you more comfortable, it can also save you money.
