What Size Should My Replacement Furnace Be?

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 on the horizon, but how do you decide the size of system you’ll need? Choosing 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.

Buying 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 lifecycle of your system. An oversized furnace will cost you more money up front and over time.

On the other hand, a system that is too small will operate too long and won’t be able to fully heat your home when the weather gets frigid. An improperly sized system will have to work harder, your energy expenses may be higher and your comfort will be affected because of that. It’s very important to work with an expert that will complete 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 decided based exclusively on square footage and was often erroneous. Technology and knowledge have made a lot of advances since then. When you’re ready for a replacement furnace, one of the professionals from Gillman Heating and Air will study your home as a whole and then be able to offer an accurate load calculation. Load calculations are made of everything from the construction of your home, amount of insulation, the local climate and type and color of your roof, to the number of home occupants – a truly all-encompassing assessment of your needs.

An accurately sized and functioning HVAC system will not only keep you more comfortable, it can also save you money. Adding a replacement furnace is a big decision, which is why we want to make sure your system will meet or exceed all of your needs. We are here to help you along for every step of the way.
