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 soon, the first step is to figure out what size of system will work properly for your indoor space. Having a correctly sized system is critical 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 ideal. Your household will waste a lot of energy and money if you choose 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 additional money up front, but it will cost you more over time as well. This is a decision you’ll want to dodge. 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 effort. A system that is too small will work harder, which will minimize the system’s life span. Also, you’ll be paying higher energy bills for a home that’s not sufficiently heated. Have a professional, like those at Air-Dynamics 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 determined based only on square footage. This method typically lead to inaccurate calculations. With advancements in technology and increased knowledge, things are much more precise today. 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 San Angelo 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 Air-Dynamics Inc, we understand that purchasing a replacement furnace is a major decision.
