HVAC Double Check

Meet Kathi Shoemake P.E., Principal Engineer with HVAC Double Check.

One of Kathi’s favorite things about working in construction and engineering is the people. Every project brings together engineers, architects, contractors, and specialists from completely different backgrounds.

As she puts it: “Every building project becomes its own kind of social experiment — mixing personalities, perspectives, and expertise to make something real.”

Engineers can be wonderfully quirky, architects often see the world in completely different ways, and contractors come from such a broad slice of the population that every project introduces new personalities and perspectives. That variety is part of what makes the industry so interesting.

Kathi originally fell into engineering somewhat unexpectedly. In college, many of her friends were studying mechanical engineering and she joined them — initially just to tag along for study sessions. But she quickly discovered she was fascinated by understanding how things work and move in the world around us.

After graduating and moving to Seattle, she shared her resume through engineering societies and connected with someone through ASHRAE. From there she began learning HVAC and plumbing design and developed a deep respect for the systems that help buildings function properly.

Her long-term goal is simple but meaningful:
To know that decades from now, people may walk through a building and the systems inside are still working well because of the care put into the design.

Her advice for women considering a career in construction or engineering:
Get hands-on and stay curious.
Don’t let someone take over a task because they assume you can’t do it. Ask questions, learn the steps behind the work, and make sure you understand the logic behind it so you can reproduce it yourself. Break big challenges into smaller steps and approach each one thoughtfully.

Some of Kathi’s most memorable moments in the field have come from exploring the hidden parts of buildings — from climbing into mechanical lofts to navigating interstitial spaces and rooftops with incredible views (even while managing a fear of heights).

Outside of work, she enjoys festivals and fairs, being in a lively crowd, shopping, and trying all kinds of different foods.

We’re proud to be part of an industry that continues to grow stronger through diverse perspectives and shared problem-solving.

A few weeks ago, our engineers spent the day at the PNW Buildings and Plants Expo in Tacoma, connecting with facility and building professionals who share our passion for efficient, sustainable systems.

The event featured hands-on demos and conversations around innovations that help buildings perform better, a mission that aligns closely with how we approach every project.

📢 Exciting News! We’re thrilled to welcome Kathi Shoemake to HVAC Double Check as she joins us full-time!

With 20 years of HVAC and plumbing design experience, Kathi has worked on projects ranging from restaurants and medical offices to correctional facilities and mixed-use developments. Her expertise in VRF systems, energy modeling, and sustainable plumbing solutions makes her an incredible asset to our team and our clients.

From Kathi: I joined HVAC Double Check to have the opportunity to be a leader. I look forward to managing my own projects. I also look forward to working on local tenant improvements that support our small business industry. I am expecting some challenging projects of size with energy and cost efficiency foremost in design.

I hope to compliment Tricia's strengths of ingenuity and flexibility with my consulting experience and outgoing personality. I'm going to bring my energy efficiency and water conservation knowledge to all our designs. I'm ready to work on industrial, retail/restaurant and medical offices again!

We are excited about the knowledge and leadership Kathi brings to the team, and we can't wait to see how she helps shape the future of HVAC Double Check. Join us in giving her a warm welcome!
