Summary:
Heat pumps don’t generate heat—they move it. Even when it’s 20°F outside, there’s still heat energy in the air that a heat pump can extract and concentrate inside your home. Think of it like a refrigerator running in reverse.
Furnaces, on the other hand, burn fuel or use electric coils to create heat from scratch. Gas furnaces combust natural gas, while electric furnaces use resistance heating—similar to your toaster, but much larger.
The key difference? Heat pumps can provide both heating and cooling from one system, while furnaces only heat. That means if you choose a furnace, you’ll still need a separate AC unit for summer comfort.
Here’s what most contractors won’t tell you upfront: older heat pump technology struggled when temperatures dropped below freezing. But today’s cold-climate heat pumps are engineered specifically for places like New York.
Modern cold-climate heat pumps maintain their efficiency down to 5°F and can operate effectively even at -13°F. That covers the vast majority of NYC winter conditions. When we do hit those rare sub-zero nights, most systems have backup electric heating that automatically kicks in.
The efficiency advantage is substantial. Heat pumps can be up to three times more efficient than gas furnaces because they’re moving heat rather than creating it. In practical terms, this means lower monthly energy bills, even with NYC’s higher electricity rates.
However, heat pump efficiency does decline as temperatures drop. At 47°F outside, a good heat pump might operate at 300% efficiency. At 5°F, that same unit might drop to 200% efficiency—still twice as efficient as a gas furnace, but the difference narrows in extreme cold.
For most NYC homeowners, this performance profile works well. The city’s average winter temperatures rarely stay below 20°F for extended periods, meaning heat pumps operate in their sweet spot most of the season.

The numbers matter more than the marketing. Let’s break down what you’ll actually spend over the life of each system.
Installation costs vary significantly based on your home’s existing setup. If you already have ductwork and gas lines, a furnace replacement might cost $3,000-$8,000. Heat pumps typically range from $5,600-$20,000 installed, with the median cost around $16,000 including available rebates.
But installation is just the beginning. Operating costs depend on your local energy prices, home insulation, and system efficiency. In most areas, heat pumps cost less to operate monthly, even with higher electricity rates.
Your monthly heating bill depends on three factors: local energy prices, system efficiency, and how much heat your home needs. In NYC, natural gas typically costs less per BTU than electricity, but heat pumps use those BTUs so much more efficiently that they often come out ahead.
A typical NYC home might spend $1,200-$2,000 per year heating with a standard gas furnace. The same home with a cold-climate heat pump might spend $800-$1,400 annually, depending on the specific equipment and home efficiency.
These savings add up. Over a 15-year system lifespan, the operating cost difference could be $3,000-$9,000 in favor of heat pumps. That helps offset the higher installation cost and can result in positive cash flow within 5-8 years.
However, your specific savings depend on your home’s characteristics. Poorly insulated homes, homes with high heating loads, or homes in areas with expensive electricity might see smaller savings or even higher costs with heat pumps.
The key is getting an accurate assessment of your home’s heating needs and local energy costs. Generic estimates from online calculators often miss important details that affect real-world performance.
New York State offers substantial incentives that can dramatically reduce heat pump installation costs. The Clean Heat program provides rebates up to $14,000 for qualifying heat pump installations, depending on the system type and your home’s current heating source.
Federal tax credits through the Inflation Reduction Act add another layer of savings. You can claim 30% of installation costs (up to specific limits) as a tax credit when you install qualifying heat pump systems. This isn’t a deduction—it’s a dollar-for-dollar reduction in your tax bill.
Utility companies also offer rebates and financing programs. Con Edison, for example, provides additional incentives for energy-efficient equipment installations in their service area.
When you stack these incentives, the effective cost of a heat pump installation can drop significantly. A $15,000 system might cost you $8,000-$10,000 out of pocket after all rebates and credits are applied.
Furnace rebates are more limited but still available. High-efficiency gas furnaces qualify for modest utility rebates, typically $300-$1,000. The savings aren’t as dramatic as heat pump incentives, but they help offset upgrade costs.
These programs change regularly, so it’s worth checking current offerings before making your decision. What’s available today might not be available next year, and some programs have limited funding that runs out during the year.
Your best heating system depends on your specific situation, not general market trends. Heat pumps make sense for many NYC homes, especially if you’re replacing both heating and cooling systems. The efficiency advantages and available rebates often tip the scales in their favor.
Furnaces still have their place, particularly in homes with existing gas infrastructure, very high heating loads, or situations where upfront cost is the primary concern. They’re also worth considering if you’re in an area where natural gas is significantly cheaper than electricity.
The smart move is getting a professional assessment of your home’s heating needs, existing infrastructure, and local energy costs. We’ve been helping NYC homeowners make these decisions for over 50 years, combining technical expertise with real-world experience to find the right solution for each situation.
