Those with existing gas infrastructure may consider furnaces or hybrids. These trade-offs lead to efficiency metrics and expected savings.

Which Heating System Is More Energy Efficient for Savannah Homes?

Energy efficiency comparisons use different ratings: HSPF/SEER for heat pumps, AFUE for furnaces. Translating to savings requires local energy prices. Heat pump installation in Savannah, GA delivers multiple units of heat per electrical energy unit in mild climates, often surpassing other options. For Savannah, where cooling dominates, a high-SEER heat pump reduces summer bills while providing efficient winter heat. The table below summarizes typical ranges and practical impacts.

System Type	Common Efficiency Metrics	Typical Range	Practical Impact
Air-source heat pump	HSPF (heating) / SEER (cooling)	HSPF 8–13; SEER 14–22	Lower combined heating/cooling costs in mild winters and long cooling season
Gas furnace	AFUE (annual fuel utilization efficiency)	AFUE 80–98%	Strong heating output; lower fuel use at higher AFUE but no cooling function
Mini-split heat pump	HSPF / SEER / Zoned control	HSPF 9–14; SEER up to 30	High efficiency with zoning; ideal for retrofit without ducts

Heat pumps generally offer better year-round energy efficiency in Savannah, especially with significant cooling loads. The next subsection outlines how heat pump ratings convert into monthly savings.

How Does Furnace Efficiency Compare in Georgia’s Weather?

Furnace efficiency (AFUE) measures fuel conversion to heat; modern gas furnaces reach 90%+ AFUE. In Savannah’s mild winters, furnaces have low annual runtime, so absolute energy savings from high-AFUE units are smaller.
