24/7 HVAC, Plumber & Electrician in Waltham, MA

Home » Waltham

Top-Rated Local Home Service Company

Traffic along Moody Street doesn’t slow down much, and neither do the heating, cooling, plumbing, and electrical systems inside Waltham homes. Between older multi-family properties near downtown, historic homes around Prospect Hill, and newer renovations closer to Route 128, homeowners across Waltham deal with a wide range of system issues throughout the year. Landry Mechanical has spent years working throughout the city, handling everything from emergency furnace repair and AC service to plumbing leaks and electrical upgrades.

You’ve likely seen our trucks moving past Bentley University, parked outside homes near Beaver Street, or navigating neighborhoods around the Charles River between calls. Some homes in Waltham still rely on aging pipes and outdated electrical panels, while newer additions and remodels often require modern HVAC systems capable of handling year-round New England weather.

When something starts failing inside your home, quick service can help prevent much larger disruptions later.

Plumbing Services

Waltham’s mix of historic homes, apartment buildings, and renovated properties creates a wide variety of plumbing challenges. Older galvanized piping, recurring drain blockages, and worn-out water heaters are all common throughout the city.

Landry Mechanical provides reliable home plumbing solutions throughout Waltham, including repairs, replacements, and emergency plumbing services.

Even small leaks can lead to costly damage in older Waltham homes. Addressing plumbing problems early usually helps avoid larger repairs and water-related damage later.

Heating & Cooling Services

Waltham homeowners rely heavily on dependable HVAC systems through freezing winters and humid summer stretches. Older heating systems often struggle during extended cold snaps, while aging AC units can have difficulty keeping up once temperatures climb into the 90s.

Landry Mechanical provides dependable HVAC repair and replacement services throughout Waltham, including furnace repair, AC service, mini split installation, and heat pump solutions.

If your heating or cooling system has become unreliable, louder than usual, or less efficient, scheduling service early can help avoid peak-season emergencies.

Electrical Services

Many Waltham homes were built decades before today’s electrical demands became standard. Once EV chargers, modern HVAC systems, home offices, and large appliances are added, older electrical systems often struggle to keep up safely.

Landry Mechanical provides licensed electrical installation and repair services throughout Waltham.

Electrical issues should never be ignored. If your home experiences repeated breaker trips, buzzing outlets, or flickering lights, it’s worth having the system professionally inspected.

I had a fantastic experience with Sam and Nick from Landry Mechanical Inc Plumbing HVAC & Electrical. Both were highly professional electricians who went above and beyond.

They took the time to clearly explain the safety benefits of arc fault breakers, which was incredibly helpful. Their expertise was proven almost immediately when one of the new breakers tripped, signaling a real issue in my home's wiring. Sam and Nick quickly troubleshot the problem, identified some poor workmanship from a previous contractor, and fixed it on the spot. Once repaired, the breaker worked perfectly.

They also moved an outlet over to another wall for me and did a beautiful, seamless job. I highly recommend Landry Mechanical, and specifically Sam and Nick, for any electrical needs in the Worcester area!

I had an odd job to fix a bathroom fan installation that was not venting properly to the available outside ducting when the bathroom fan was changed as part of a bath remodel. It had been vented to the outside several years ago as part of a Mass Save house insulation upgrade project. Through the Angie website, they recommended Landry Mechanical and they took the job, communicated well, scheduled a visit within two days, and fixed the problem! Mike pulled out the fan and connected it correctly to the ducting. I mentioned about checking if it's now really venting to the outside like it should. He offered to take a look at where it vents outside to see if the louvers were open when the fan is running and they barely were. Wondering if the ducting was even connected correctly, Mike then went into the attic to take a look at the ducting, which was underneath cellulose insulation we had blown in as part of a Mass Save insulation job a few years ago. He said there were bends in the ducting that would cause resistance free to air flow, so not ideal. He didn't have the proper tools for doing rigid ducting work (as his specialty is electrical), but said he'd check with the HVAC part of the company to see if there's anything they could do, so waiting on that, but I was happy just to get someone in who's willing to do that kind of job when it doesn't fit neatly into the company's specific areas of expertise and the price was quite reasonable and took the time to answer all my questions and made sure I was satisfied! I am considering changing to using them for their AC/Heat/Plumbing/Electrical annual service program when my exiting contract with another company expires.

Excellent experience with Landry’s Mechanical!
Bill did an outstanding job with my EV charger installation. From the beginning, he was friendly, professional, and took the time to clearly explain the quote and the work that needed to be done. The price was very fair, and there were no surprises.

The installation was completed quickly, and the workmanship was excellent. Everything was done perfectly, and I couldn’t be happier with the finished installation. Bill made the entire process easy and stress-free.

I’m extremely happy with the work and would absolutely recommend Bill and Landry’s Mechanical to anyone looking for quality electrical work.

I had a fantastic experience with these guys. The entire team was incredibly friendly and professional from Tim, the person who came out to give my quote, to Julian and Marcus and the rest of the team who did the work. They were very kind, professional, patient in educating me and accommodating my specific requests, and they were all super respectful of me and my home during the job. The units themselves have transformed my home with their quiet and efficient cooling. Thank you so much to the whole team at Landry!
