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 properly for your indoor space. Having a correctly sized system is key to its efficiency and the comfort level of your house. With some research, you’ll select the perfect furnace for your needs. When replacing your system, bigger isn’t always the best. You will waste a lot of energy and money if you install a system that is too large. A system that is too large won’t have to run as long, so it’ll be consistently 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 a decision you’ll want to avoid. Then there are the issues with a system that is too small. If your system is too small, it will run more frequently to try to heat your house, and it won’t be able to get the job done despite its effort. A smaller than needed will work harder, which will decrease the system’s life span. Also, you’ll be paying higher utility bills for a home that’s not sufficiently heated. Have a professional, like those at WM J Kraus & Son complete 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 frequently lead to inappropriate calculations. With advancements in technology and increased knowledge, things are much more precise today. 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 take into consideration the climate in Keokuk and the number of people live in your home. This assessment is unquestionably much more thorough than coming up with a calculation created on square footage alone! If your HVAC system is appropriately sized it will keep you more comfortable and save costs. At WM J Kraus & Son, we understand that buying a replacement furnace is a big decision.
