What Size Should My Replacement Furnace Be?02/29/2016 What Size Should My Replacement Furnace Be? If you’re looking for a replacement furnace or will be soon, the first step is to determine what size of system will work properly for your indoor space. Having an appropriately sized system is key to its efficiency and the comfort level of your home. With a bit of research, you’ll find the perfect furnace for your needs. When replacing your system, bigger isn’t always the best. You will waste a lot of energy and money if you choose a system that is bigger than you need. A system that is larger than you need won’t have to run as long, so it’ll be consistently cycling on and off, which causes extra wear on your system and can reduce the life of your system. An oversized system will not only cost additional money up front, but it will cost you more over time as well. This is a choice you’ll want to stay away from. Then there are the challenges with a system that is smaller than you need. If your system is too small, it will run too often to try to heat your home, and it won’t be able to get the job done despite its work. A system that is too small will work harder, which will decrease the system’s life span. Also, you’ll be paying higher utility bills for a home that’s not adequately heated. Have a professional, like those at PWA Heating & Cooling Inc perform a load calculation and consult with you on the best system for your replacement furnace needs. How is Load Calculation Determined? In the past, a home’s load calculation was determined based only on square footage. This method frequently lead to inaccurate calculations. With advancements in technology and improved knowledge, things are much more precise now. Your furnace professional will review your home as a whole, looking at factors like its construction, the color of its roof and how well insulated it is. He or she will also think about the climate in Plainfield and how many people live in your home. This assessment is certainly much more thorough than determining a calculation based on square footage alone! If your HVAC system is correctly sized it will keep you more comfortable and save you money. At PWA Heating & Cooling Inc, we understand that getting a replacement furnace is a huge decision.
