Good food, friendly competition, and even better company! ☀️

Our Simmer Down with Shafer Picnic was a great opportunity to bring our Shafer family together for a day of fun outside of work!

We enjoyed some delicious BBQ, watched Residential and Commercial go head-to-head in a friendly game of flag football, and had a special piñata for the kids to enjoy!

At Shafer, taking care of people like family starts with our own team. Events like these remind us how important it is to spend time together, build relationships, and celebrate the people who make Shafer such a special place to work.

A big thank you to everyone who joined us and helped make the day so memorable!

Yesterday, our Shafer team came together for our Q3 Quarterly Meeting to reflect on our progress, celebrate accomplishments, and look ahead to what's next!

These meetings are about more than reviewing goals and company updates. They're an opportunity to recognize the hard work happening across every department, strengthen our connections, and make sure we're all moving forward together.

As Shafer continues to grow, one thing remains the same: our commitment to taking care of people like family, supporting one another, and creating meaningful careers in the trades.

We're grateful for every team member who plays a part in making Shafer what it is today. Here's to finishing the year strong and continuing to grow together!

When cooling tower issues threaten building operations, every detail matters.

At Methodist Metropolitan Professional Building, our Shafer Mechanical team stepped in to replace a cooling tower motor, perform precision laser alignment, and investigate a second tower cell where a locked-up gearbox was discovered.

Our technicians successfully restored operation to one of the two cooling tower cells, brought the central plant back online, and proactively monitored chiller performance until the building's heat load was recovered.

The result? Restored cooling operations, an identified solution for the remaining tower cell, and minimal disruption to the facility.

That's the difference experienced troubleshooting and a team committed to doing the job right can make.

When multiple plumbing systems need attention, the last thing a facility manager needs is multiple service visits to get the job done.

For one national facilities client, Shafer Mechanical coordinated the replacement of failed commercial water treatment equipment, RO system service, and an important code compliance improvement during a single visit.

The result? A completed scope, verified system performance, and no additional return visit required for the planned work.

See how thoughtful coordination and attention to detail helped simplify this commercial plumbing project for the facility team: https://shafermechanical.com/case-study-commercial-water-treatment-system-replacement/
