How can I make my Holliston home’s HVAC system more energy efficient?

Regular maintenance, upgrading to a programmable thermostat, and sealing duct leaks are simple steps that improve efficiency. Our team can also recommend modern systems with higher SEER ratings for maximum savings on your energy bills.

What are the most common plumbing issues in older Holliston homes?

Historic homes in Holliston often face aging pipe corrosion, outdated fixtures, or low water pressure. Replacing old plumbing materials and scheduling routine inspections helps prevent leaks and long-term water damage.

Should I install a whole-home surge protector?

Yes, it’s one of the best ways to safeguard your electronics and appliances from power surges. Given Holliston’s frequent seasonal storms, surge protection can prevent costly damage to your home’s electrical system.

Why is my air conditioner freezing up in the summer?

A frozen AC can result from dirty filters, low refrigerant levels, or restricted airflow. It’s a common issue during humid Holliston summers and should be checked by a professional before it leads to compressor damage.

How do I know if my water heater is the right size for my household?

If your family runs out of hot water often, your water heater may be undersized. Our Holliston plumbers can perform a capacity assessment and recommend the best tank or tankless model based on your daily usage.

Very professional very nice took the time to replace an item in my bathroom sink didn’t charge me for it also helped me with a device that was attached to my washing machine that needed to be detached which they didn’t hesitate to help me with, but the biggest thing was when they came into the house And handed me my brother’s wallet that had cash in it. They found it on my driveway You can’t get more trustworthy than that

Jorge Gonzales from Landry arrived on time today to check out the faucet in my shower. I was not getting enough hot water but all other faucets were fine. He quickly found that the rubber gasket on the cartridge had deteriorated, replaced it, and left my shower as clean as he found it. Jorge was courteous, friendly and professional. I would not hesitate to have him come and do additional work for me. Landry is lucky to have him!

I cannot say enough how happy I am for choosing Landry. Sam Reynolds and Josh Clough came out one day to look at an electrical repair, gave me an estimate then came back the next day to do the repair. Sam and Josh worked in 15 degrees weather, did a great job, frendly and accommodating, I would recommend them to anyone. Thank Mike Massauro

Outstanding Service!! Our company had a main drain clog, and it was important that we get the line open so we could use the building. Within 1 hr. they had a team over lead by Matt S. and he walked us through the entire process. We even got to look through the pipe camera to see the condition of the pipe after it was cleared. And no, it did not cost us an arm and a leg! Considering the quick service, not losing down time from work and the work they did, it was reasonable. We would highly recommend them and will use them in the future. The staff at Gurney Water Treatment, Sutton MA.
