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 soon, you’ll need to figure out what size of system will work best 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 better. You will waste a lot of energy and money if you choose 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 means 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 a choice you’ll want to dodge. Then there are the problems with a system that is smaller than necessary. 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 effort. A smaller than needed will work harder, which will decrease the system’s life span. Also, you’ll be paying higher utility bills for a home that’s not adequately heated. Have a professional, like those at Guidry's Air Conditioning & Refrigeration Service complete a load calculation and chat 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 often lead to incorrect calculations. With advancements in technology and better knowledge, things are much more precise now. Your furnace professional will study your home as a whole, looking at factors 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 Raceland and how many people live in your home. This assessment is definitely much more thorough than determining a calculation created on square footage alone! If your HVAC system is properly sized it will keep you more comfortable and save costs.
