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 rapidly approaching, but how do you figure out the size of system you’ll need? Choosing the correct size is crucial for your system’s efficiency and your home’s comfort. There’s a perfect furnace out there for you and your comfort 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 always 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 decreases the lifespan 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 small will stay on too long and won’t be able to fully heat your home when the weather gets chilly. An incorrectly sized system will have to work harder, your energy costs may be higher and your comfort will be impacted because of that. It’s very important to speak with a pro that will do a load calculation and advise you on the best system for your needs.

How is Load Calculation Determined?

A home’s load calculation used to be calculated based only on square footage and was often erroneous. Technology and knowledge have evolved a lot since then. When you’re ready for a replacement furnace, one of the professionals from Davis Heating & Air Conditioning 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 comprehensive assessment of your needs.

A properly sized and functioning HVAC system will not only keep you more comfortable, it will also save you money.
