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 shortly, you will need to figure out what size of system will work best for your indoor space. Having a correctly sized system is key to its efficiency and the comfort level of your house. With some 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 choose a system that is larger than necessary. 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 causes extra wear on your system and can reduce 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 decision you’ll want to avoid. Then there are the challenges with a system that is smaller than necessary. If your system is too small, it will run more often to try to heat your house, and it won’t be able to get the job done despite its work. A too-small system will work harder, which will minimize the system’s life span. Plus, you’ll be paying higher energy bills for a home that’s not sufficiently heated. Have a professional, like those at Patterson & Stirling 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 figured based only on square footage. This method often lead to inaccurate calculations. With advancements in technology and increased knowledge, things are much more precise nowadays. 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 think about the climate in Erie and the number of people live in your home. This assessment is certainly much more thorough than determining a calculation based on square footage alone! If your HVAC system is properly sized it will keep you more comfortable and save on expenses. At Patterson & Stirling Inc, we understand that purchasing a replacement furnace is a major decision.
