What Size Should My Replacement Furnace Be?

What Size Should My Replacement Furnace Be?

If you are ready for a replacement furnace or will be shortly, the first step is to determine what size of system will work properly for your house. Having an accurately sized system is key to its efficiency and the comfort level of your indoor space. With a little 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 pick a system that is bigger than you need. A system that is too large won’t have to run as long, so it’ll be frequently cycling on and off, which can mean extra wear on your system and can shrink the life of your system. An oversized system will not only cost additional 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 smaller than necessary. 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 too-small system will work harder, which will minimize the system’s life span. Additionally, you’ll be paying higher utility bills for a home that’s not adequately heated. Have a professional, like those at Contra Costa Heating & AC complete 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 determined based only on square footage. This method often lead to inappropriate calculations. With advancements in technology and improved 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 think about the climate in the Bay Area and how many people live in your home. This assessment is definitely 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.
