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, you’ll need to figure out what size of system will work most appropriately for your indoor space. Having an accurately sized system is important to its efficiency and the comfort level of your house. With some research, you’ll find the perfect furnace for your needs. When replacing your system, bigger isn’t always better. You will waste a lot of energy and money if you pick a system that is larger than necessary. 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 extra 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 problems with a system that is smaller than necessary. If your system is too small, it will run more frequently to try to heat your space, and it won’t be able to get the job done despite its work. A system that is too small will work harder, which will decrease the system’s life span. Plus, you’ll be paying higher utility bills for a home that’s not appropriately heated. Have a professional, like those at Woody's Sudden Service Inc complete a load calculation and consult 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 improved knowledge, things are much more precise nowadays. Your furnace professional will review 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 consider the climate in Manassas Park and the number of people live in your home. This assessment is definitely much more thorough than coming up with 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 Woody's Sudden Service Inc, we understand that purchasing a replacement furnace is a huge decision.
