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 approaching quickly, but how do you decide the size of system you’ll need? Selecting 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 comfort 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 production will not require it to operateas long. This is known as “short cycling” and it increases the wear on your system and in turn hurts the lifespan of your system. An oversized system will cost you more money up front and down the road. On the other hand, a system that is too little will operate too long and won’t be able to fully heat your home when the weather gets cold. An inadequately sized system will have to work harder, your bills may be higher and your comfort will be impacted because of that. It’s very important to work with a professional that will perform 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 determined 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 KDM Service Corporation will study your home as a whole and then be able to give 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 could also save you money.
