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 figure out 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 budget. When replacing your system, bigger isn’t always better. Buying a system that is too large wastes energy and money. A larger system will constantly 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 hurts the lifespan of your system. An oversized unit will cost you more money up front and over time. On the other hand, a system that is too little will run too long and can’t fully heat your home when the weather gets frigid. An inadequately sized system will have to work harder, your energy expenses will be higher and your comfort will be impacted because of that. It’s very important to talk to 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 determined based solely on square footage and was often erroneous. Technology and knowledge have come a long way since then. When you’re ready for a replacement furnace, one of the professionals from Davis Heating & Air Conditioning will study your home as a whole and then be able to give an accurate load calculation. Load calculations are made of 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. An accurately sized and functioning HVAC system will not only keep you more comfortable, it can also save you money.
