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 soon, you will need to figure out what size of system will work most appropriately for your house. Having an appropriately sized system is important to its efficiency and the comfort level of your indoor space. With a bit of research, you’ll 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 pick a system that is too large. A system that is too big 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 shrink 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 dodge. Then there are the challenges with a system that is too small. If your system is too small, it will run more frequently to try to heat your home, 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. Also, you’ll be paying higher heating bills for a home that’s not adequately heated. Have a professional, like those at Polestar Plumbing, Heating & Air Conditioning perform 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 frequently lead to inappropriate calculations. With advancements in technology and better knowledge, things are much more precise nowadays. Your furnace professional will study 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 Olathe and how many people live in your home. This assessment is unquestionably much more thorough than coming up with a calculation established on square footage alone! If your HVAC system is properly sized it will keep you more comfortable and save costs.
