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, the first step is to determine what size of system will work best for your home. Having an accurately sized system is critical to its efficiency and the comfort level of your home. With some research, you’ll be able to find the perfect furnace for your needs. When replacing your system, bigger isn’t always ideal. 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 large won’t have to run as long, so it’ll be consistently cycling on and off, which means 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 a choice you’ll want to avoid. Then there are the problems with a system that is too small. If your system is too small, it will run too often to try to heat your house, 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 energy bills for a home that’s not adequately heated. Have a professional, like those at Air Houston Mechanical LLC 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 assumed based only on square footage. This method typically lead to inappropriate calculations. With advancements in technology and better knowledge, things are much more precise nowadays. Your furnace professional will review 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 think about the climate in Humble and the number of people live in your home. This assessment is certainly much more thorough than determining a calculation established on square footage alone! If your HVAC system is properly sized it will keep you more comfortable and save costs. At Air Houston Mechanical LLC, we understand that purchasing a replacement furnace is a big decision.
