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 shortly, the first step is to identify what size of system will work most appropriately for your home. Having a correctly sized system is critical to its efficiency and the comfort level of your house. With some research, you’ll be able to find the perfect furnace for your needs. When replacing your system, bigger isn’t always ideal. Your household will waste a lot of energy and money if you choose a system that is larger than necessary. A system that is larger than you need 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 shrink 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 avoid. Then there are the issues with a system that is smaller than you need. 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 effort. A too-small system will work harder, which will shorten 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 KDM Service Corporation 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 figured based only on square footage. This method often lead to incorrect calculations. With advancements in technology and increased knowledge, things are much more precise today. Your furnace professional will examine your home as a whole, looking at things like its construction, the color of its roof and how well insulated it is. He or she will also consider the climate in Tuscaloosa and the number of people live in your home. This assessment is definitely much more thorough than determining a calculation based on square footage alone! If your HVAC system is properly sized it will keep you more comfortable and save costs.
