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 most appropriately for your indoor space. Having an appropriately sized system is key to its efficiency and the comfort level of your indoor space. With a bit of research, you’ll find the perfect furnace for your needs. When replacing your system, bigger isn’t always the best. Your home will waste a lot of energy and money if you install a system that is larger than necessary. A system that is too big 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 additional money up front, but it will cost you more over time as well. This is a decision 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 too often to try to heat your space, and it won’t be able to get the job done despite its exertion. A smaller than needed will work harder, which will minimize the system’s life span. Plus, you’ll be paying higher heating bills for a home that’s not appropriately heated. Have a professional, like those at Controlled Comfort HVAC Inc do a load calculation and confer 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 inaccurate calculations. With advancements in technology and improved knowledge, things are much more precise today. Your furnace professional will review 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 Carpentersville and how many people live in your home. This assessment is certainly much more thorough than coming up with a calculation established on square footage alone! If your HVAC system is properly sized it will keep you more comfortable and save on expenses. At Controlled Comfort HVAC Inc, we understand that getting a replacement furnace is a major decision.
