Should You Replace a Gas Furnace with a Heat Pump

Switching from a gas furnace to a heat pump can be a financially and environmentally sound decision. One Reddit user shared their experience with this upgrade, and their real-world data provides a great case study for homeowners considering the switch. This article breaks down their findings while also covering important considerations for HVAC contractors, including the best HVAC insurance options and HVAC insurance costs.

Why Consider a Heat Pump Over a Gas Furnace?

A traditional gas furnace may seem like the most cost-effective way to heat your home due to lower natural gas prices. However, heat pumps provide a much higher efficiency rate by moving heat instead of generating it. This makes them a viable alternative, especially in moderate climates.

Key Cost Comparisons

  • Electricity costs: $0.30-$0.40/KWh
  • Natural gas costs: $0.08/KWh ($2.35/therm)
  • Heat pump Coefficient of Performance (COP): 3.62 at 47°F
  • Gas furnace efficiency: 80% (AFUE rating)

In this user's experience, their heat pump used 1 KWh of electricity to move 3.62 KWh of heat into their home. In contrast, their old gas furnace used 1 KWh of gas to provide only 0.8 KWh of heat. This efficiency advantage makes heat pumps more cost-effective under certain conditions.

When Does a Heat Pump Save Money?

If electricity costs less than 4.53 times the price of natural gas, a heat pump is the cheaper option. In this case:

  • At $0.30/KWh for electricity, the heat pump cost was $0.083/KWh-heat
  • The old gas furnace cost $0.10/KWh-heat
  • Total savings: 17%

However, heat pumps lose efficiency in colder weather. At 17°F, this user's heat pump had a COP of only 2.44, making the heat pump more expensive to operate than their old furnace at that temperature. But because it rarely gets that cold in their area, the heat pump remained the better option overall.

HVAC Contractors and Insurance Considerations

If you're an HVAC contractor installing heat pumps, you need proper insurance coverage. Here's what to consider:

Best HVAC Insurance Coverage

  1. General Liability Insurance – Covers third-party bodily injury, property damage, and completed operations.
  2. Workers’ Compensation – Required in most states to cover employee injuries.
  3. Commercial Auto Insurance – Protects vehicles used for transporting equipment and materials.
  4. Equipment and Tools Coverage – Covers the cost of stolen or damaged HVAC tools.
  5. Professional Liability Insurance – Protects against claims of faulty work or errors in installation.

HVAC Insurance Cost Breakdown

  • General Liability Insurance: $500-$2,000 per year
  • Workers’ Compensation: Varies by state and payroll, often $2,000-$5,000 annually
  • Commercial Auto: $1,200-$3,000 per vehicle per year
  • Equipment Coverage: $300-$1,500 per year, depending on coverage limits

So Should You Switch to a Heat Pump?

This Reddit user’s experience highlights the benefits of replacing an old gas furnace with a heat pump, especially in mild climates. For HVAC contractors, the growing demand for heat pumps presents an opportunity—but also a need for proper HVAC insurance. Ensuring you have the right coverage protects your business and helps you take advantage of the increasing shift toward energy-efficient heating solutions.
