Why a Bigger Furnace Isn’t Better

A bigger furnace isn’t always better for your Blue Bell, Pennsylvania, home. If your furnace is too large, it will waste energy, raise your utility bills, and make your home less comfortable. Oversized furnaces come on and turn off often, so they don’t dehumidify the air well. This can encourage mold growth and make your home feel clammy or stuffy. They’re also more expensive, they don’t last as long, and they can cause warm or cold areas in your home. An HVAC professional will use a Manual J load calculation to find the right size furnace for your home.

Manual J

The Manual J load calculation from the Air Conditioning Contractors of America considers the amount of square footage in your home, the amount and type of insulation, the number of windows, the amount of shade outside your home, the number of residents, and more. The capacity of a furnace is measured in British thermal units (BTUs). The most common sizes range from 40,000 to 100,000 BTUs, and most professionals recommend installing the smallest, most efficient system possible for your home.

Keeping Comfortable

Furnaces that are too big tend to make annoying noise and they can’t keep your home’s temperature constant. If your ducts are too large, an oversized furnace still won’t be able to move air fast enough throughout your home. If the ducts are too small for the unit installed, noise will be a problem because of increased air pressure. Professionals use Manual D to find the best size unit for existing ductwork.

Avoiding Expenses

A properly sized furnace should run smoothly all the time on the coldest days. That way, you can heat your home without wasting energy and remain comfortable regardless of the range of outdoor temperatures. Invest in a smaller, more efficient furnace to lower your utility bills and save money.
