Heating and Cooling, Plumbing & Electrical in Holliston, MA
Local & Family-Owned Home Service Company
Our service trucks are a regular fixture along Washington Street and the residential avenues surrounding the Upper Charles Rail Trail. We understand the specific demands of Holliston’s housing stock, where meticulously kept colonial properties in the Mudville neighborhood sit alongside mid-century ranches and newer builds near the Sherborn line. Maintaining these homes requires a technical partner familiar with the local climate’s impact on older infrastructure, from the heavy moisture levels near Lake Winthrop to the high energy demands of modern households.
Reach out to our team to coordinate your next home service visit.

Mine was just an annual tune up. Mr . Torres showed up well ahead of time and got the job done in no time. He took all my questions and proved himself to be very knowledgeable in what he does. The job is half done and the rest is expected to be done soon but i am fully satisfied and will be knocking on Landry’s door next year for another tune up, God willing!

We had an outstanding experience from start to finish with Landry HVAC, plumbing and mechanical. Tim L. came out to assess our cooling needs and utilized a LiDAR scanner to ensure that our rooms were properly fitted with the right-sized mini-split units. He addressed every question we had, which set a wonderful tone and made us feel completely comfortable and confident in our decision to move forward with Landry.
Avah served as our dedicated point of contact, and both she and Tim provided prompt, kind, and clear communication throughout the entire process.
Gavin, our lead technician, did an incredible job and is truly a star in his role. He was professional, communicative, and thorough in explaining every step of the installation. We are very pleased with how Gavin and our second technician, Kyle, handled the units, wiring, covers, and the condenser. Gavin provided us with information on how to use, clean and maintain our new mini split units. They were incredibly respectful of our property and took great care to keep our home clean. Additionally, Don the electrician did fantastic work with the electrical components to ensure our system was running safely and smoothly.
This was truly the "dream team," and I cannot recommend Landry highly enough. We will certainly utilize them for all maintenance and future services for our home.
