What Size Should My Replacement Furnace Be?02/29/2016 What Size Should My Replacement Furnace Be? If it’s time for a replacement furnace or will be in the near future, the first step is to determine what size of system will work most appropriately for your indoor space. Having an appropriately sized system is critical to its efficiency and the comfort level of your indoor space. With some research, you’ll find the perfect furnace for your needs. When replacing your system, bigger isn’t always ideal. Your household will waste a lot of energy and money if you install 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 constantly 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 a choice you’ll want to avoid. Then there are the issues with a system that is smaller than necessary. If your system is too small, it will run too often to try to heat your space, and it won’t be able to get the job done despite its exertion. A system that is too small will work harder, which will decrease the system’s life span. Additionally, you’ll be paying higher heating bills for a home that’s not sufficiently heated. Have a professional, like those at Fleming Heating & Air Conditioning Inc. complete 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 assumed based only on square footage. This method typically lead to inaccurate calculations. With advancements in technology and improved knowledge, things are much more precise now. 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 consider the climate in South Beloit and Belvidere and the number of people live in your home. This assessment is unquestionably much more thorough than providing a calculation created on square footage alone! If your HVAC system is appropriately sized it will keep you more comfortable and save costs.
