This is a simplified estimate based on Manual J principles. An on-site assessment by a licensed HVAC contractor is required for accurate sizing. Factors like ductwork condition, air sealing, and specific window types affect the final recommendation.

Alabama is in Climate Zone 3 - Warm-Humid/Warm-Dry (moderate heating and cooling). Homes here typically have higher cooling demands than heating.
Our calculator factors in multiple variables that affect your heating and cooling expenses:
Sometimes high energy costs signal an underlying issue that needs professional attention:
It varies widely based on climate, home size, and efficiency. Average US households spend $1,000-$2,000 annually on heating and cooling. In extreme climates or larger homes, it can be $3,000-$5,000 or more.
It depends on local rates. Natural gas is typically cheaper per BTU in most of the US, but heat pumps can be more efficient in moderate climates. Compare your local gas and electric rates to determine which is more economical.
Upgrading from a 10 SEER to a 16 SEER AC can reduce cooling costs by 35-40%. Upgrading from an 80% to 95% efficient furnace saves about 15% on heating. Actual savings depend on your current system and usage.
Studies show smart thermostats save 10-15% on heating and cooling costs on average. The savings come from optimizing schedules and avoiding heating/cooling an empty house.
