What Size Should My Replacement Furnace Be?02/29/2016 What Size Should My Replacement Furnace Be? If it’s time for a replacement furnace or will be soon, the first step is to figure out what size of system will work properly for your home. Having an accurately sized system is important to its efficiency and the comfort level of your indoor space. With a little research, you’ll select the perfect furnace for your needs. When replacing your system, bigger isn’t always the best. Your household will waste a lot of energy and money if you choose a system that is too large. A system that is too big won’t have to run as long, so it’ll be frequently cycling on and off, which causes extra wear on your system and can lessen 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 choice you’ll want to dodge. Then there are the problems with a system that is smaller than you need. 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 work. A smaller than needed will work harder, which will shorten 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 Davis Heating & Air Conditioning 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 typically lead to inaccurate calculations. With advancements in technology and better 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 Rocky Mount and how many people live in your home. This assessment is certainly much more thorough than providing a calculation based on square footage alone! If your HVAC system is correctly sized it will keep you more comfortable and save you money. At Davis Heating & Air Conditioning, we understand that getting a replacement furnace is a big decision.
