What Size Should My Replacement Furnace Be?02/29/2016 What Size Should My Replacement Furnace Be? If you are ready for a replacement furnace or will be in the near future, you’ll need to identify what size of system will work best for your home. Having an accurately sized system is critical to its efficiency and the comfort level of your indoor space. With a bit of research, you’ll be able to 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 pick a system that is larger than necessary. 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 extra money up front, but it will cost you more over time as well. This is a choice you’ll want to dodge. Then there are the problems with a system that is smaller than necessary. If your system is too small, it will run too often to try to heat your house, and it won’t be able to get the job done despite its effort. A too-small system will work harder, which will minimize the system’s life span. Additionally, you’ll be paying higher heating bills for a home that’s not appropriately heated. Have a professional, like those at Twin Air LLC do a load calculation and chat 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 incorrect calculations. With advancements in technology and increased knowledge, things are much more precise today. Your furnace professional will study your home as a whole, looking at things like its construction, the color of its roof and how well insulated it is. He or she will also consider the climate in Manassas and the number of people live in your home. This assessment is certainly much more thorough than providing 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 Twin Air LLC, we understand that getting a replacement furnace is a huge decision.
