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, the first step is to figure out what size of system will work most appropriately for your indoor space. Having a correctly sized system is key to its efficiency and the comfort level of your indoor space. With some research, you’ll select the perfect furnace for your needs. When replacing your system, bigger isn’t always the best. Your home will waste a lot of energy and money if you install a system that is too large. A system that is too large won’t have to run as long, so it’ll be consistently cycling on and off, which causes extra wear on your system and can reduce 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 stay away from. Then there are the problems with a system that is smaller than necessary. 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 effort. A smaller than needed will work harder, which will minimize the system’s life span. Additionally, you’ll be paying higher energy bills for a home that’s not adequately heated. Have a professional, like those at Dial One Mears Air Conditioning & Heating Inc perform a load calculation and confer 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 figured based only on square footage. This method frequently lead to incorrect calculations. With advancements in technology and improved knowledge, things are much more precise nowadays. Your furnace professional will examine 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 Phoenix and the number of people live in your home. This assessment is unquestionably much more thorough than coming up with a calculation established on square footage alone! If your HVAC system is properly sized it will keep you more comfortable and save you money.
