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 in the near future, you will need to identify what size of system will work best for your indoor space. Having an appropriately sized system is critical to its efficiency and the comfort level of your indoor space. With a little research, you’ll find the perfect furnace for your needs. When replacing your system, bigger isn’t always the best. You 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 constantly cycling on and off, which causes extra wear on your system and can reduce 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 an option you’ll want to avoid. Then there are the issues with a system that is too small. 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 utility bills for a home that’s not appropriately heated. Have a professional, like those at Street Heating & Sheet Metal Inc complete 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 often lead to inappropriate calculations. With advancements in technology and increased knowledge, things are much more precise nowadays. Your furnace professional will study 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 Rapid City and how many individuals live in your home. This assessment is unquestionably much more thorough than providing 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 Street Heating & Sheet Metal Inc, we understand that buying a replacement furnace is a major decision.
