    Lavallee Systems recently installed an air source heat pump, and I’m extremely happy with the entire experience. Sam was incredibly thorough with his design process—he performed a full Manual J calculation and used that data to recommend the appropriately sized heat pump for my home. Jon and his team were professional, efficient, and showed great attention to detail throughout the installation. The office staff was also very helpful and ensured that the permit was closed on time.

    I’m writing this as I sit comfortably in my house at -10F, the coldest temperature in Boston since 1957. We had a very nice heating system installed by another contractor who unfortunately didn’t really understand how to set it up or service it. I called in Lavallee at the recommendation of my general contractor. Sam was extremely helpful and clearly knowledgeable about HVAC. Their technician John did a great job fixing the setup of the system to get it working smoothly. I also used their plumbers and they did a great job on our tankless water heater. I recommend Lavallee highly and would definitely use them again.Services: HVAC system repair

    Their crew came to our home and analyized multiple temperature issues. We had minisplits installed in two areas and now we are finally comfortable all year round! Would highly recommend.
