An improperly sized HVAC unit can wreak havoc on your home. An oversized unit can cause your system to “short cycle” – constantly turning off and on. An undersized unit will run constantly to keep up with demand. Consider the factors below and choose an HVAC system that works best for your home.

SIZE MATTERS
The square footage of your home can help determine the load capacity of your HVAC unit, but it should not be the only factor considered when reviewing unit sizes. Enlist the help of a licensed professional to determine the best HVAC unit for your home.

HOME’S ORIENTATION
How sunlight hits your home during dif­ferent times of the day impacts the load capacity required to properly heat or cool your home.

GEOGRAPHICAL LOCATION
The region in which your home is located will factor into how much capacity you need per square foot.

INSULATION EFFECTIVENESS
The better insulated your home is, the fewer BTUs (British Thermal Units) per square foot your home will need to stay at the desired temperature.

A reliable energy partner will help you determine how each of these factors affect your system’s load capacity. Visit JOEMC’s Energy Efficiency Resources Page for more ways to save money!
