How Each System Works
Heat Pumps
Heat pumps don't create heat—they move it. In winter, they extract heat from outdoor air (even when it's cold) and bring it inside. In summer, they reverse the process to cool your home.
Key Components:
- • Outdoor unit with compressor
- • Indoor air handler
- • Refrigerant lines
- • Reversing valve
Efficiency: For every 1 unit of electricity used, heat pumps deliver 3-4 units of heating/cooling.
Gas Furnaces
Furnaces burn natural gas to create heat, which is then distributed through your home via ductwork. They provide powerful, consistent heat regardless of outdoor temperature.
Key Components:
- • Burners and combustion chamber
- • Heat exchanger
- • Blower motor
- • Exhaust vent
Efficiency: Modern furnaces achieve 80-98% efficiency, meaning some heat is always lost through exhaust.

Which System Is Right for Your NJ Home?
Choose a Heat Pump If...
- ✓ You want lower operating costs and maximum efficiency
- ✓ You're replacing both heating and cooling systems
- ✓ You have or are installing solar panels
- ✓ You want to reduce your carbon footprint
- ✓ Your home has good insulation
- ✓ You want to take advantage of maximum rebates
Choose a Furnace If...
- ✓ You have existing gas lines and want lower upfront costs
- ✓ Your home has poor insulation or drafts
- ✓ You prioritize consistent heat in extreme cold
- ✓ You already have a newer AC system
- ✓ You prefer traditional heating systems
- ✓ Gas prices in your area are very low
Consider a Dual-Fuel System If...
- ✓ You want the best of both worlds
- ✓ You have existing gas lines but want efficiency
- ✓ You want guaranteed comfort in extreme weather
- ✓ You can afford a slightly higher installation cost
- ✓ You want to maximize year-round efficiency
How it works: Heat pump runs most of the time for efficiency, furnace kicks in only during extreme cold (below 30°F).
Our Expert Recommendations for NJ Homes
Based on 15+ Years Serving NJ
For Most NJ Homes:
We recommend a cold-climate heat pump with a HSPF2 rating of 8.5 or higher. Models from Mitsubishi, Daikin, or Carrier work excellently in NJ winters and provide significant energy savings.
For Homes with Gas Lines:
Consider a dual-fuel system combining a heat pump with a gas furnace backup. This provides maximum efficiency above 30°F and reliable heat during polar vortex events.
For Older Homes:
If your home has poor insulation or significant air leaks, address these issues first. Then, a high-efficiency gas furnace (95%+ AFUE) might be more practical until envelope improvements are made.
For New Construction:
Always choose a heat pump. With proper insulation and air sealing in new homes, heat pumps provide superior comfort and efficiency without the need for gas infrastructure.
