What Size Should My Replacement Furnace Be?02/29/2016 What Size Should My Replacement Furnace Be? If you’re looking for a replacement furnace or will be shortly, you will need to identify what size of system will work properly for your indoor space. Having an accurately sized system is critical to its efficiency and the comfort level of your indoor space. With some 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 pick a system that is larger than necessary. A system that is too big won’t have to run as long, so it’ll be consistently cycling on and off, which can mean 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 an option you’ll want to stay away from. Then there are the problems with a system that is too small. If your system is too small, it will run too often to try to heat your house, and it won’t be able to get the job done despite its work. A smaller than needed 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 Banister's Heating & Air Conditioning Services 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 typically lead to inaccurate calculations. With advancements in technology and better knowledge, things are much more precise now. Your furnace professional will review your home as a whole, looking at items like its construction, the color of its roof and how well insulated it is. He or she will also consider the climate in Carlsbad and how many individuals live in your home. This assessment is unquestionably 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 you money.
