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, the first step is to figure out what size of system will work best for your indoor space. Having an appropriately sized system is critical to its efficiency and the comfort level of your home. 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. Your household will waste a lot of energy and money if you choose a system that is larger than necessary. A system that is too big won’t have to run as long, so it’ll be frequently 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 additional money up front, but it will cost you more over time as well. This is an option you’ll want to stay away from. Then there are the challenges with a system that is smaller than necessary. If your system is too small, it will run more frequently to try to heat your house, 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. Also, you’ll be paying higher heating bills for a home that’s not appropriately heated. Have a professional, like those at C-N-O Comfort Zone complete 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 typically lead to incorrect 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 things like its construction, the color of its roof and how well insulated it is. He or she will also take into consideration the climate in Saint Peters and the number of people live in your home. This assessment is certainly much more thorough than providing a calculation established on square footage alone! If your HVAC system is correctly sized it will keep you more comfortable and save costs. At C-N-O Comfort Zone, we understand that buying a replacement furnace is a major decision.
