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 will need to identify what size of system will work most appropriately for your indoor space. Having an appropriately sized system is important to its efficiency and the comfort level of your home. With some 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 large won’t have to run as long, so it’ll be consistently cycling on and off, which causes extra wear on your system and can lessen 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 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 space, 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. Additionally, you’ll be paying higher energy bills for a home that’s not adequately heated. Have a professional, like those at B & G HVAC perform 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 assumed based only on square footage. This method often lead to incorrect calculations. With advancements in technology and better 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 Marshalltown and how many people live in your home. This assessment is certainly much more thorough than determining a calculation established on square footage alone! If your HVAC system is appropriately sized it will keep you more comfortable and save costs. At B & G HVAC, we understand that purchasing a replacement furnace is a huge decision.
