Choosing a new furnace isn’t just about brand or efficiency ratings—size matters. One of the most common and costly mistakes homeowners make is installing a furnace that’s either too large or too small for their home. An improperly sized furnace can lead to higher energy bills, uneven heating, frequent repairs, and a shorter system lifespan.
