What Size Should My Replacement Furnace Be?02/29/2016 What Size Should My Replacement Furnace Be? If you’re looking 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 an accurately sized system is important to its efficiency and the comfort level of your indoor space. With a bit of 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 bigger than you need. A system that is too large 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 too small. If your system is too small, it will run more often to try to heat your space, and it won’t be able to get the job done despite its effort. A system that is too small will work harder, which will minimize the system’s life span. Also, you’ll be paying higher energy bills for a home that’s not appropriately heated. Have a professional, like those at Service Plus Mechanical complete a load calculation and consult with you on the best system for your replacement furnace needs. How is Load Calculation Determined?

With advancements in technology and improved knowledge, things are much more precise nowadays.

He or she will also take into consideration the climate in Aurora and how many individuals live in your home.
