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, you will need to figure out what size of system will work most appropriately for your indoor space. Having a correctly sized system is important to its efficiency and the comfort level of your home. With some research, you’ll find the perfect furnace for your needs. When replacing your system, bigger isn’t always better. Your household will waste a lot of energy and money if you choose a system that is bigger than you need. 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 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 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 too often 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 decrease the system’s life span. Also, you’ll be paying higher heating bills for a home that’s not appropriately heated. Have a professional, like those at Ilten's Incorporated do a load calculation and confer with you on the best system for your replacement furnace needs. How is Load Calculation Determined?

With advancements in technology and better knowledge, things are much more precise nowadays. Your furnace professional will examine your home as a whole, looking at items 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 Cedar Rapids and how many people live in your home.
