As the heating season approaches, it’s crucial to make informed decisions about your home’s heating and cooling systems. At Superior CO-OP HVAC, we specialize in Mitsubishi air-to-air heat pumps, and in this post, we’ll cover everything from the different types of heat pumps to their efficiency, cost, and the latest 2025 rebates and tax credits available in New York and Vermont. This guide will help you understand how heat pumps can save you money and reduce your carbon footprint while keeping your home comfortable year-round—especially while current federal incentives are still available.
Guide to Heat Pumps: What Are the Different Types?
Choosing the right type of heat pump is essential for achieving the best results. Here are the most common types available:
- Air-to-Air Heat Pumps: These systems transfer heat between indoor and outdoor air, making them ideal for North Country climates. Ducted air source heat pumps can integrate with existing ductwork to provide whole-home heating and cooling, working similarly to a central air conditioner.
- Air-to-Water Heat Pumps: These use outdoor units similar to air-to-air models, but distribute heat through a hot-water radiator system.
- Geothermal Heat Pumps: Also known as ground-source heat pumps, these systems use the stable temperature of the earth to provide heating and cooling. Ground-source or geothermal heat pumps are highly efficient because they don’t have to compensate for big temperature swings like air-source heat pumps do.
- Water-Source Heat Pumps: These heat pumps use water as the medium for heat exchange.
- Hybrid Heat Pumps: These systems combine a heat pump with a traditional furnace or boiler for enhanced efficiency.
Air-source heat pumps are the most common type of home heat pumps for residential heating and cooling.
When installing heat pumps, existing ducts must be inspected for leaks and proper sizing. If no ducts exist, a mini split heat pump—also called a ductless mini split system—can be used for targeted heating and cooling.
Electric heat pumps are energy-efficient HVAC systems that transfer thermal energy from the environment to heat homes. They can replace both heating and air conditioner systems, offering an efficient solution for home heat pumps.
At Superior CO-OP HVAC, we specialize in Mitsubishi air-to-air heat pumps that provide high efficiency and reliable comfort, even in cold climates.
Ground Source Heat Pumps
Ground source heat pumps, often called geothermal heat pumps, harness the steady temperature found beneath the earth’s surface to deliver reliable heating and cooling year-round. This type of heat pump system uses a network of pipes buried underground—known as a ground loop—filled with a special fluid that absorbs geothermal heat in the winter and disperses excess heat back into the ground during the summer. Because the earth’s temperature remains relatively constant, ground source heat pumps can achieve exceptional energy efficiency, often reducing energy bills by up to 50% compared to traditional heating and cooling systems.
One of the biggest advantages of ground source heat pumps is their minimal environmental impact. Unlike systems that burn fossil fuels, geothermal heat pumps do not produce greenhouse gas emissions, making them a smart choice for homeowners looking to lower their carbon footprint. They also offer long-term savings, as their high efficiency means less energy is required to maintain comfortable indoor temperatures.
However, installing a ground source heat pump can be more complex and costly than other types of heat pumps, due to the need for underground piping. The suitability of a geothermal system depends on your property’s soil conditions, available land, and terrain. Despite the higher upfront investment, many homeowners find that the long-term savings and environmental benefits of ground source heat pumps make them a worthwhile option for efficient, sustainable heating and cooling.
Ducted Heat Pumps
Ducted heat pumps are a versatile solution for whole-home heating and cooling, especially in houses that already have a duct system in place. This type of heat pump works by distributing warm or cool air through a network of ducts, much like a traditional central air conditioning system. The key difference is that ducted heat pumps are designed to provide both heating and cooling from a single, energy-efficient system.
For homeowners with larger spaces or multiple rooms to condition, ducted heat pumps can deliver a consistent flow of warm or cool air throughout the entire home. They are ideal for those who want the comfort of central air without the high energy costs associated with older systems. Because they use existing ductwork, installation can be straightforward in homes that already have a duct system, making it easier to upgrade to a more efficient heat pump system.
While ducted heat pumps offer powerful performance and whole-home comfort, they can be more expensive to install than ductless options, especially if new ductwork is needed. They may also require regular maintenance to keep the duct system clean and efficient. Still, for many homeowners, the ability to enjoy both heating and cooling from a single, efficient heat pump makes ducted systems an excellent choice.

Natural Gas: How Does It Compare to Heat Pumps?
Natural gas has long been a popular choice for home heating, but when compared to modern heat pump technology, there are some important differences to consider. Heat pumps are able to transfer heat rather than generate it by burning fossil fuels, which means they can deliver up to four times more energy than the electricity they consume. In contrast, natural gas furnaces typically operate at 80–90% efficiency, meaning a portion of the energy is lost during combustion.
This higher efficiency translates into lower energy bills for homeowners who choose a heat pump system over a natural gas furnace. Additionally, heat pumps do not rely on burning fossil fuels, so they help reduce greenhouse gas emissions and support a cleaner environment. For those looking to minimize their carbon footprint and save on long-term energy costs, heat pumps are a compelling alternative.
However, natural gas furnaces can have a lower upfront installation cost and may be a practical option in areas where electricity is less accessible or more expensive. Ultimately, the choice between natural gas and a heat pump system depends on your home’s infrastructure, local energy prices, and your priorities for efficiency and environmental impact.
