What Is a Heat Pump?
A heat pump doesn't create heat – it moves it. Think of it as an AC unit that runs in reverse:
How Heat Pumps Work
- Heating Mode: Extracts heat from outdoor air (yes, even cold air contains heat!) and moves it inside
- Cooling Mode: Reverses operation, removing heat from inside and releasing it outside (just like your AC)
- Year-Round System: Replaces both furnace AND air conditioner
Types of Heat Pumps
Air-Source Heat Pumps (most common):
- Extract heat from outdoor air
- Work well above 30°F
- Cost: $5,000-7,500
- What we're comparing here
Cold-Climate Heat Pumps (newer technology):
- Work efficiently to 5°F, function to -13°F
- Better for Pennsylvania
- Cost: $7,000-8,500
- Still need backup below 15-20°F
Ground-Source (Geothermal):
- Extract heat from ground (constant 50-55°F)
- Work in any PA climate
- Cost: $15,000-30,000
- Beyond this comparison's scope
✅ Heat Pump Advantages
- Dual function: Heating + cooling in one system
- High efficiency: 250-350% efficiency in mild weather

What Is a Gas Furnace?
A gas furnace burns natural gas to create heat, then distributes it through your home's ductwork. Simple, proven, reliable – especially in Pennsylvania winters.
How Furnaces Work
- Thermostat calls for heat when temperature drops
- Gas burners ignite creating flame
- Heat exchanger heats air (combustion gases vented outside)
- Blower fan distributes warm air through ducts
- Cycle repeats until desired temperature reached
Furnace Efficiency Levels
80% AFUE (Standard Efficiency):
- Cost: $2,500-3,500
- 80 cents of every gas dollar creates heat
- Single-stage operation
- Good for mild climates or budgets
92-96% AFUE (High Efficiency):
- Cost: $3,500-4,800
- 96 cents of every dollar creates heat
