For Wellesley homeowners, the search for a single, reliable solution for both heating and cooling ends here.

As a leading provider of heat pump solutions in the Wellesley area, Lavallee Systems specializes in designing and installing systems perfectly tailored to the unique architecture and demands of local homes. Whether you live in a historic property or a modern build, we have the expertise to seamlessly integrate a high-efficiency heat pump that elevates your comfort and lowers your utility bills.
Modern heat pump technology has evolved dramatically, dispelling old myths about their performance in cold climates. Today’s cold-climate air-source heat pumps are engineered to operate with incredible efficiency even when temperatures drop well below freezing, making them a powerful and reliable primary heat source for Massachusetts winters.

Unlike traditional furnaces that burn fuel to create heat, a heat pump works by intelligently transferring it. In the winter, it extracts heat from the outside air (even when it's cold) and moves it inside. In the summer, it reverses the process—extracting heat from inside your home and moving it outdoors, functioning just like a high-efficiency air conditioner. This transfer method is far more efficient than heat generation, leading to substantial energy savings.
Choosing the correct heat pump is critical for maximizing comfort and efficiency. Lavallee Systems helps you navigate the options to find the perfect match for your home’s specific needs.
The most popular choice for residential applications, these systems are versatile and highly effective. They come in two main configurations:
If your home already has ductwork from a traditional furnace or central AC system, a ducted heat pump can integrate directly. This provides consistent, even heating and cooling to every room connected to the system.
For homes without existing ductwork, or for additions, sunrooms, and specific zones, ductless systems are an ideal solution. They consist of one outdoor unit connected to one or more indoor air handlers, offering room-by-room temperature control and incredible efficiency.
These systems leverage the stable temperatures deep in the earth to transfer heat. While they involve a larger initial investment, they offer unparalleled efficiency and the lowest long-term operating costs, making them a premium choice for ultimate energy independence.
Upgrading to a heat pump with Lavallee Systems is an investment in both your comfort and your future. The advantages extend far beyond simply heating and cooling your home.
By moving heat instead of creating it, heat pumps operate at 300% to 400% efficiency—meaning for every unit of electricity they consume, they produce three to four units of heat. This translates directly into lower monthly energy bills compared to oil, propane, or traditional electric resistance heating systems.
Heat pumps are an all-electric technology. By switching, you eliminate on-site combustion of fossil fuels, drastically cutting your home's carbon emissions. When paired with the increasingly green energy grid, you make a powerful choice for a healthier environment.
The transition to clean energy is strongly supported in our community. Residents of Wellesley, MA, are eligible for substantial financial incentives through programs offered by the Wellesley Municipal Light Plant (WMLP) and the statewide Mass Save initiative. These rebates can cover a significant portion of the installation cost, making this upgrade more affordable than ever. Our experts will guide you through every step to ensure you maximize every available rebate and tax credit.
