What Size Should My Replacement Furnace Be?

You’ve come to the point where it’s time for a furnace replacement or perhaps you see this point approaching quickly, but how do you figure out the size of system you’ll need? Selecting the right size is critical for your system’s efficiency and your home’s comfort. There’s a perfect furnace out there for you and your home’s needs.

When replacing your system, bigger isn’t always better.

Putting in a system that is too large wastes energy and money. A larger system will constantly be warming up and cooling down because it’s production will not require it to operateas long. This is known as “short cycling” and it increases the wear on your system and in turn hurts the life of your system. An oversized furnace will cost you more money up front and in the long run.

On the other hand, a system that is too little will run too long and can’t fully heat your home when the weather gets frigid. An inadequately sized system will have to work harder, your energy expenses will be higher and your comfort will suffer because of that. It’s very important to speak with a professional that will perform a load calculation and advise you on the correct system for your needs.

How is Load Calculation Determined?

A home’s load calculation used to be determined based only on square footage and was often wrong. Technology and knowledge have evolved a lot since then. When you’re ready for a replacement furnace, one of the pros from AC Sales will study your home as a whole and then be able to provide an accurate load calculation. Load calculations are composed of everything from the construction of your home, amount of insulation, the local climate in addition to type and color of your roof, to the number of home occupants – a truly all-encompassing assessment of your needs.
