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, the first step is to determine what size of system will work properly for your home. Having a correctly sized system is key to its efficiency and the comfort level of your house. With a little 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 pick 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 shrink 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 problems with a system that is smaller than you need. If your system is too small, it will run more frequently to try to heat your house, and it won’t be able to get the job done despite its effort. A too-small system will work harder, which will minimize the system’s life span. Additionally, you’ll be paying higher heating bills for a home that’s not sufficiently heated. Have a professional, like those at Central Air Inc do 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 assumed based only on square footage. This method frequently lead to inaccurate calculations. With advancements in technology and increased knowledge, things are much more precise today. Your furnace professional will examine 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 Portland Metro and how many people live in your home. This assessment is certainly much more thorough than determining a calculation created on square footage alone! If your HVAC system is appropriately sized it will keep you more comfortable and save on expenses. At Central Air Inc, we understand that buying a replacement furnace is a major decision.
