Heating and cooling account for nearly 50% of energy consumption in residential buildings. Traditional HVAC systems rely on fossil fuels and refrigerants which contribute to greenhouse gas emissions.
It is time to trade in the oil, propane or gas you might currently be using to heat and cool your house. Please consider heat pumps. There are many reasons.
Like your refrigerator, heat pumps use electricity to transfer heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. During warmer months, the heat pump is in the cooling mode. It uses a refrigerant to transfer warm air from inside your home to the outdoors. During colder months, the heat pump operates like an air conditioner in reverse. The refrigerant transfers warmth from the outside air to inside your home.
They are air conditioning systems with a reversing valve that allows one unit to provide both cooling and heating. Plus, advanced zone controls provide greater flexibility for customized comfort, with energy efficient heat pump technology.
These systems, particularly when powered by renewable energy, are significantly more efficient than fossil fuel-based furnaces and air conditioners. They are typically three to five times more energy-efficient than natural gas boilers.

During colder months, they operate like air conditioners in reverse with the refrigerant transferring warmth from the outside air to inside your home.
Geothermal (ground source) heat pump systems extract heat from the ground during cold weather via an underground pipe system. The ground remains a constant temperature 10 feet below the earth’s surface, regardless of how cold the air outside is, and that heat is distributed throughout your home. During the summer, the process is reversed to provide cooling to your home. They can reduce electricity use by up to 50% and have a lifespan of over 50 years.
Yes. Today’s heat pumps are better than ever. Modern cold-climate air source heat pump engineering has evolved to include features that were not available a decade ago, such as variable-speed, inverter-driven compressor technology and improved defrost-cycle controls. As a result, today’s cold-climate air source heat pumps work in very cold weather. While it is true that in years past, traditional air source heat pumps were less effective when temperatures dropped below freezing, a modern cold-climate heat pump does not have these challenges. In fact, research shows that cold-climate heat pumps can provide comfortable domestic heating when it is as cold as -15°F outside — and that’s air temperature, not wind chill!
Yes. There are ductless mini-splits which are ideal for any room or small spaces. They provide cooling and heating without the hassle of installing ductwork.
By adopting heat pump technology, homeowners and businesses can drastically cut their reliance on fossil fuels, reducing their carbon footprint and contributing to climate change mitigation efforts. Specifically.
Improving a home's insulation and upgrading to energy-efficient windows will further enhance the performance of any HVAC system and lower overall energy use.
The federal government and many state governments are offering incentives and rebates for installing heat pumps, making them a cost-effective long-term investment. Some links follow.
