Heat Pump vs Traditional HVAC: Quick Comparison

Traditional HVAC System

Components:

• Gas or electric furnace (heating)
• Central air conditioner (cooling)
• Separate systems, separate efficiency ratings

How It Works:

• Heating: Furnace burns fuel (gas/oil) or uses electric resistance
• Cooling: AC compressor extracts heat from indoor air

Efficiency:

• Gas furnace: 80-98% AFUE (Annual Fuel Utilization Efficiency)
• Electric furnace: 95-100% AFUE (but expensive to operate)
• AC unit: 13-20 SEER (Seasonal Energy Efficiency Ratio)

Heat Pump System

Components:

• Single unit handles both heating and cooling
• Air-source or ground-source (geothermal) options

How It Works:

• Heating: Extracts heat from outdoor air (even when cold) and transfers indoors
• Cooling: Extracts heat from indoor air and transfers outdoors
• Efficiency: 200-400% efficiency (moves heat, doesn't create it)

Efficiency:

• Air-source heat pump: 8-12 HSPF (Heating Seasonal Performance Factor), 14-20 SEER
• Geothermal heat pump: 3.5-5.0 COP (Coefficient of Performance), 20-30 EER
