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 shortly, 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 home. With a little research, you’ll select the perfect furnace for your needs. When replacing your system, bigger isn’t always ideal. Your home will waste a lot of energy and money if you pick a system that is bigger than you need. 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 lessen the life of your system. An oversized system will not only cost more 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 smaller than necessary. 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 too-small system will work harder, which will shorten the system’s life span. Plus, you’ll be paying higher heating bills for a home that’s not adequately heated. Have a professional, like those at ACS Inc 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 figured based only on square footage. This method typically lead to inappropriate calculations. With advancements in technology and increased knowledge, things are much more precise now. 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 consider the climate in Metro Atlanta and how many people live in your home. This assessment is certainly much more thorough than providing a calculation based on square footage alone! If your HVAC system is properly sized it will keep you more comfortable and save costs.
