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 approaching quickly, but how do you decide the size of system you’ll need? Choosing the correct size is very important 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. 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 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 reduces the life of your system. An oversized system will cost you more money up front and in the long run. On the other hand, a system that is too little will stay on too long and will not be able to fully heat your home when the weather gets cold. An incorrectly sized system will have to work harder, your energy expenses could be higher and your comfort will be affected because of that. It’s very important to work with an expert 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 determined based exclusively on square footage and was often incorrect. Technology and knowledge have evolved a lot since then. When you’re ready for a replacement furnace, one of the professionals from Oak Grove Heating & Air Conditioning will study your home as a whole and then be able to offer an accurate load calculation. Load calculations include 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. An accurately sized and functioning HVAC system will not only keep you more comfortable, it can also save you money.
