Selecting the Most Appropriate Home Heating System: Heat Pump or a Furnace

Heating from winter is comfortable but, most importantly, safe and efficient. At Cornerstone Services, we understand how important it is for one's heating capability to prove its worth in the cold. If you're weighing the pros and cons between a heat pump and a furnace, you're in good company; both systems have their advantages and disadvantages, and that will depend on climate factors, energy costs, and how the whole setup is in your home. Let's find out how to make a wise decision.

What is a Heat Pump?

A heat pump, for instance, can heat up or cool down your house. Rather than generating heat, it transfers heat from one place to another. In the wintertime, it takes heat from the outside air (yes!)—even if that air is cold—and puts it into the house. In the summertime, it reverses the process and releases heat. The efficiency of heat pumps lies in moderate climates since they do not burn fuel at all on their own.

What is a Furnace?

A furnace is a heating system that burns fuel like natural gas, propane, or electricity to produce heat and distributes that heat through ductwork into your home. They work very well for winter climates because they produce a very high heat output, no matter how cold it is outside.

Key Differences between Heat Pump and Furnace

Cost Comparison

Heat pumps usually cost more to install than a furnace but save far more on energy costs. An average furnace may be cheaper to install but may start seeing fuel price increases in operation. 

Energy Efficiency 

A heat pump is energy efficient because it moves heat. However, on days when it gets extremely cold, it might not be able to keep up the efficiency. On the other hand, a furnace can be highly efficient, but it consumes fuel as it does so.

Performance-based on Climates

Heat pumps are best for locations with moderate climates and mild winters. However, they're great in icy areas like New Hampshire, where winter temperatures are often below freezing.

Maintenance and Life Span

The heat pump runs constantly, requiring maintenance twice per year. Compared to fifteen years for a heat pump, the furnace will require less attention and last twenty years or more.

Installation Requirements

When you have ductwork, installation shouldn't be complicated for either. For someone with no ducts, a ductless heat pump (mini-split system) makes the most sense for a furnace requiring new ducting.

Advantages and Disadvantages of Heat Pumps

✔️ Reduced operating costs and energy-efficient

✔️ Both heating and cooling

✔️ Environment friendly: no fossil fuels are used for heating

❌ Initial installation costs are high

❌ Uneconomical in freezing weather

❌ Shorter lifespan than furnace

Pros and Cons of Heat Pumps

✔️ Energy-efficient and lower operating costs

✔️ Provides both heating and cooling

✔️ Environmentally friendly - no fossil fuels required

❌ Higher initial installation costs

❌ Less effective in freezing weather

❌ Shorter life span than furnace

Pros and Cons of Furnaces

✔️ Reliable heating in below-freezing temperatures

✔️ Lower initial installation costs

✔️ Longer lifespan with proper maintenance 

❌ Higher energy costs in the long run 

❌ May lead to emissions (if powered by gas) 

❌ Not an all-in-one heating-cooling solution 

Best Heating System Based on Climate

The furnace is almost always your preferred option in New Hampshire, where winter temperatures often drop well below freezing. It reliably provides high heat for whatever short time the temperatures may reach. On the other hand, if your home has mild winters or you want an energy-efficient option, a heat pump may be a perfect fit. Some of the newer heat pumps are designed to work in colder climates but come with a price premium.

Tax Credits & Rebates for Energy-Efficient Systems

Both heat pumps and high-efficiency furnaces may qualify for federal tax credits under the Inflation Reduction Act, covering up to 30% of installation costs. Local utilities may provide rebates, so do check with them!

Why Professional Installation is Everything

After all, selecting a heating system is only half the battle; the other half is the installation itself. If your furnace or heat pump is not properly installed, it will lead to high energy bills, frequent breakdowns, and shortened system life. Choosing a professional HVAC team ensures that your system operates efficiently and comfortably for years to come.
