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 soon, you will need to determine what size of system will work most appropriately for your house. Having an appropriately sized system is key to its efficiency and the comfort level of your house. With a little research, you’ll find the perfect furnace for your needs. When replacing your system, bigger isn’t always better. Your home will waste a lot of energy and money if you pick a system that is bigger than you need. 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 shrink 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 issues with a system that is too small. If your system is too small, it will run more frequently to try to heat your space, and it won’t be able to get the job done despite its work. A smaller than needed will work harder, which will decrease the system’s life span. Additionally, you’ll be paying higher heating bills for a home that’s not appropriately heated. Have a professional, like those at Holiday Heating & Air Conditioning do 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 determined based only on square footage. This method frequently lead to inappropriate calculations. With advancements in technology and improved knowledge, things are much more precise nowadays. 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 take into consideration the climate in Ballwin and how many individuals live in your home. This assessment is unquestionably much more thorough than determining a calculation created on square footage alone! If your HVAC system is appropriately sized it will keep you more comfortable and save costs.
