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 shortly, the first step is to identify what size of system will work properly for your home. Having an appropriately sized system is key to its efficiency and the comfort level of your home. With a little research, you’ll select the perfect furnace for your needs. When replacing your system, bigger isn’t always better. Your household will waste a lot of energy and money if you choose a system that is too large. A system that is too large won’t have to run as long, so it’ll be frequently cycling on and off, which means 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 decision you’ll want to dodge. Then there are the problems with a system that is too small. If your system is too small, it will run more frequently to try to heat your home, and it won’t be able to get the job done despite its work. A too-small system 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 appropriately heated. Have a professional, like those at McNatt 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 determined based only on square footage. This method often lead to incorrect 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 factors like its construction, the color of its roof and how well insulated it is. He or she will also consider the climate in Corpus Christi and how many people live in your home. This assessment is unquestionably much more thorough than providing 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 McNatt Inc, we understand that purchasing a replacement furnace is a major decision.
