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 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 budget. 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 runas long. This is known as “short cycling” and it increases the wear on your system and in turn decreases the life 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 won’t be able to fully heat your home when the weather gets chilly. An inadequately sized system will have to work harder, your energy expenses could be higher and your comfort will be impacted 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 decided based exclusively 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 pros from Southern Heating & Cooling Inc. will study your home as a whole and then be able to provide an accurate load calculation. Load calculations are made 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 comprehensive assessment of your needs. A properly sized and functioning HVAC system will not only keep you more comfortable, it can also save you money.
