Signed. Sealed. Delivered. Inspected. ✅

Another commercial kitchen project across the finish line.

This build included:
• 2 grease traps
• 4 three-bay sinks
• 1 massive pizza oven

The equipment is installed, the inspections are complete, and everything is operating exactly the way it should.

At the end of the day, commercial plumbing isn’t just about pipes and fixtures. It’s about reliability. It’s about giving business owners the confidence that their systems will perform when they need them most.

The job is finished, the kitchen is ready, and the owner can get back to focusing on the business instead of worrying about what’s happening behind the walls.

That’s the goal every time.

🎥 Full project video drops next week.

Every install tells a story.

This project in Londonderry featured a 150,000 BTU heat-only system with five heating zones and one future-ready zone built in for expansion.

From removing an old oil tank and reclaiming valuable space to cleaning up existing piping and creating a more serviceable system, every detail was designed with long-term reliability in mind.

✔️ 5 Heating Zones
✔️ 1 Future Zone
✔️ Clean Mechanical Room
✔️ Improved Serviceability
✔️ Built for Efficiency & Reliability

At JDavey, we believe great work isn’t just about what gets installed.

It’s about how it’s installed.

What do you think of this setup?

Not all venting materials are installed the same.

That’s why we use Centrotherm on many of our heating system projects.
✔️ Cleaner installation
✔️ No toxic primer and glue
✔️ Faster installation process
✔️ Meets Massachusetts code requirements

At JDavey, we don’t just focus on the equipment. We focus on every part of the installation.
The materials behind the walls matter just as much as the equipment itself.

If you’re investing in a new heating system, make sure you’re working with a provider that values quality from start to finish.

The worst time to look for an HVAC company is when your AC has already stopped working.

When it’s hot, you’re uncomfortable, and you need someone fast, it’s easy to end up calling the first company you find.

That’s why we always tell people to find a provider they trust before they need one. Someone who’s going to give you honest advice, explain your options, and help you make the right decision for your home.

Not every problem has a quick fix. But you should always get a straightforward solution and an honest answer.

That’s how we do things at J. Davey Mechanical.

✔️ Full HVAC System
✔️ Navien Tankless Water Heater

When you're renovating a home, every system has to work together. Plumbing. Heating. Cooling. Hot water. Gas. Venting. The details behind the walls matter just as much as the finishes you see when it's done.

Projects like this are why contractors, builders, and homeowners trust our team. We don't just install equipment—we help create homes that are efficient, reliable, and built to perform for decades.

For the homeowner, that means comfort, efficiency, and peace of mind.
For the contractor, it means having a mechanical partner who can handle every moving piece and keep the project moving forward.

One project. One team. Done right.
