Heating and Cooling, Plumbing & Electrical in Mendon, MA

Home » Mendon

Local & Family-Owned Home Service Company

Operating along the historic crossroads of Route 16 and Route 140 requires a deep understanding of Mendon’s unique residential landscape. We’ve been navigating the quiet lanes near Southwick’s Zoo and the scenic shores of Lake Nipmuc for years, providing technical expertise to both colonial-era farmhouses and contemporary developments. Because many properties in town rely on private wells and septic systems rather than municipal lines, maintaining the integrity of your home’s mechanical infrastructure is vital for daily comfort and safety.

Reach out to our team today to coordinate your next HVAC, plumbing, or electrical service visit.

Heating & Cooling

Mendon experiences significant seasonal shifts, with winter snowfall often exceeding 50 inches and humid summers that demand reliable climate control. We ensure your systems are prepared for the peak of each season, focusing on efficiency and consistent performance throughout the year.

Schedule your heating or air conditioning service today.

Plumbing Services

With very limited public water and gas service available in town, Mendon homeowners face specific challenges regarding well pumps and specialized piping. Our technicians are well-versed in the requirements of local private systems, ensuring your water remains clean and your lines stay clear.

Call today to request a plumber to evaluate your Mendon home’s system.

Electrical Services

The historic nature of the Mendon Center district often means dealing with aging wiring that wasn’t designed for today’s power-heavy appliances. We provide modern electrical solutions that respect the architectural integrity of your property while bringing your home up to current safety standards.

Contact us online or call today to book an electrician for your next electrical repair, upgrade, or installation project. 

Drain & Sewer

Since the town does not provide a municipal sewer service, keeping your drains and septic connections in top shape is essential to avoid property damage. We use advanced diagnostic tools to identify blockages and clear lines before they lead to significant backups in your yard or basement.

Connect with us for a thorough drain inspection or to schedule sewer line repair or replacement services.

From the sales team (Tim) to the installation team (Keith, Zach, and many more) these folks have done an outstanding job removing our old system and installing a new full HVAC system. Everyone has been professional and thorough in their work and very easy to deal with from start to finish. Thanks so much!

I was very impressed with the professionalism, knowledge, kindness and class that was shown by my install team, Gavin and Kyle. They explained everything and answered all of our questions.

They did an amazing job replacing my ac system. My mom came home on hospice on a Wednesday. And my central air died that same day. Called them and they came right out Thursday morning to diagnose the problem. Tuesday the following week they were here bright and early. They finished up the install Wednesday. They were professional, neat clean and prompt. I highly recommend them!

I had a scheduled annual check up of my furnace, which was installed around nine years ago. Corey was very nice. Let me know everything was fine. Gave me a couple of optional upgrades. If I was interested Landry get me informed as to when Cory would be showing up. I like the fact that they are certified employees. Great company. UPDATE. My annual furnace update again by Joe and again had a wonderful experience with Landry He was very thorough explained everything no pressure to take his suggestions which I know I will do just not at this moment. I do appreciate the staff and the service that I get from Lang.

Clean, respectful, responsive, polite and knowledgeable. Now a days these qualities are scarce and not to be taken lightly because the competition costs as much (or more) and they will trash your house and talk to you down when you ask for a description of the problem… I only say this because it was part of my personal experience with a different company and it was very discouraging.

Your guys were very professional and explained everything in detail. Snaking a drain can be very messy but they keep everything clean and organized.
