What Size Should My Replacement Furnace Be?

If it’s time 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 house. Having an accurately sized system is key to its efficiency and the comfort level of your house. With some research, you’ll be able to find the perfect furnace for your needs.

When replacing your system, bigger isn’t always the best.

You will waste a lot of energy and money if you choose a system that is bigger than you need. A system that is too big won’t have to run as long, so it’ll be constantly 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 more 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 necessary. 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 effort. A smaller than needed will work harder, which will shorten the system’s life span. Additionally, you’ll be paying higher utility bills for a home that’s not sufficiently heated. Have a professional, like those at Oak Grove Heating & Air Conditioning perform 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 frequently lead to inappropriate calculations. With advancements in technology and increased knowledge, things are much more precise today. Your furnace professional will examine 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 take into consideration the climate in Hattiesburg and the number of people 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 on expenses.
