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 on the horizon, but how do you decide the size of system you’ll need? Picking the best 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. 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 operateas long. This is known as “short cycling” and it increases the wear on your system and in turn reduces the lifespan 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 undersized will run too long and will not be able to fully heat your home when the weather gets cold. An improperly sized system will have to work harder, your bills will be higher and your comfort will be affected because of that. It’s very important to speak with a pro that will do 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 only on square footage and was often incorrect. Technology and knowledge have made a lot of advances since then. When you’re ready for a replacement furnace, one of the professionals from Air Temperature Control 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 and type and color of your roof, to the number of home occupants – a truly all-encompassing assessment of your needs. A properly sized and functioning HVAC system will not only keep you more comfortable, it will also save you money.
