What Size Should My Replacement Furnace Be?02/29/2016What 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 figure out the size of system you’ll need? Choosing the right 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 home’s needs. When replacing your system, bigger isn’t always better. Putting in a system that is too large wastes energy and money. A larger system will always be warming up and cooling down because it’s productivity 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 unit will cost you more money up front and in the long run. On the other hand, a system that is undersized will operate too long and won’t be able to fully heat your home when the weather gets frigid. An incorrectly sized system will have to work harder, your bills may be higher and your comfort will suffer because of that. It’s very important to work with an expert 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 calculated based solely 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 WM J Kraus & Son will study your home as a whole and then be able to provide an accurate load calculation. Load calculations are composed 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 complete assessment of your needs. A properly sized and functioning HVAC system will not only keep you more comfortable, it could also save you money.
