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 soon, you will need to determine what size of system will work properly for your house. Having a correctly sized system is critical to its efficiency and the comfort level of your indoor space. With a bit of research, you’ll select the perfect furnace for your needs. When replacing your system, bigger isn’t always ideal. You will waste a lot of energy and money if you install a system that is too large. A system that is too large won’t have to run as long, so it’ll be consistently cycling on and off, which can mean 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 decision you’ll want to avoid. Then there are the issues 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 effort. A system that is too small will work harder, which will decrease the system’s life span. Additionally, you’ll be paying higher utility bills for a home that’s not appropriately heated. Have a professional, like those at James Heating & A/C, Inc do a load calculation and confer 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 often lead to inappropriate calculations. With advancements in technology and better knowledge, things are much more precise nowadays. Your furnace professional will examine your home as a whole, looking at items like its construction, the color of its roof and how well insulated it is. He or she will also think about the climate in Lexington and the number of people live in your home. This assessment is definitely much more thorough than providing a calculation established on square footage alone! If your HVAC system is appropriately sized it will keep you more comfortable and save you money. At James Heating & A/C, Inc, we understand that buying a replacement furnace is a huge decision.
