When the cold New England winter settles over Wellesley, a reliable and efficient furnace isn’t just a luxury—it’s an absolute necessity.

Selecting a new furnace is a major decision. The right choice depends on your home’s size, energy preferences, and budget. Lavallee Systems installs all major furnace types and provides professional guidance to ensure the best fit for your needs.

Gas furnaces remain the most popular heating option in Massachusetts due to their efficiency and affordability.
Advantages: Natural gas costs less than electricity, lowering monthly heating bills. Gas furnaces also heat up quickly, delivering warm air almost instantly. Their reliability and high efficiency make them ideal for harsh winters.
Considerations: A natural gas line is required. Installation must include proper connection and ventilation, demanding certified expertise for safety—something Lavallee Systems ensures with every project.
Electric furnaces offer a versatile, easy-to-install alternative for homes without natural gas access.
Advantages: Lower upfront cost, high durability, and long lifespan due to fewer moving parts. Installation is simpler and suitable for many home types.
Considerations: Operating costs can be higher since electricity is generally more expensive. However, for smaller or well-insulated homes, an electric furnace remains a highly effective and efficient solution.
