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, the first step is to figure out what size of system will work most appropriately for your house. Having a correctly 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 the best. Your household will waste a lot of energy and money if you pick a system that is too large. A system that is larger than you need won’t have to run as long, so it’ll be constantly 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 additional money up front, but it will cost you more over time as well. This is a decision you’ll want to stay away from. Then there are the issues with a system that is smaller than you need. 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 work. A smaller than needed will work harder, which will decrease the system’s life span. Additionally, you’ll be paying higher energy bills for a home that’s not appropriately heated. Have a professional, like those at B & B Heating & Cooling 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 determined based only on square footage. This method often lead to inaccurate calculations. With advancements in technology and improved knowledge, things are much more precise now. 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 take into consideration the climate in Florissant and the number of 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 costs. At B & B Heating & Cooling, we understand that purchasing a replacement furnace is a major decision.
