What Our Clients Say About Us

No other company offers the same breadth of products, solutions and services as Pro Mechanical Services. We are leading the way in solving our customer’s specific business problems with innovative, integrated solutions.

“De Leon Foods has been using Pro Mechanical Services for our HVAC, refrigeration and security needs for the past eight years. They provide equipment and services in each of our businesses, to include four bars and two grocery stores. We are very pleased with their comprehensive preventative maintenance plan tailored to our unique needs. As we continue to grow, we view Pro Mechanical Services as a strategic partner for all our mechanical services needs.”

– Sergio De Leon

“We looked around and interviewed several companies before selecting Pro Mechanical Services to be our mechanical services partner. Pro is my HVAC/controls contractor at more than 30 locations. Tim and crew have always provided first-class service for maintenance and equipment replacement. We have been very happy with Pro and would recommend them to anyone.”

– Jim Hall

When I returned to NorthTown Mall in March 2022, I was disappointed to see so many lights out. Over two-thirds of the common area lights were out. I was looking for the right company to partner with, and a chance meeting with Jim Waltz of Pro Mechanical Services got the ball rolling. He put together an excellent proposal that made the light replacement an easy sell to company leadership. We were able to get half of our lights replaced and are now working on getting the second half of our lights. Jim and the team at Pro Mechanical were true pro’s and I look forward to working with them in future.

Pro Mechanical has been a wonderful partner to us in the completion of many large construction projects throughout the downtown core of Spokane, WA. Their project managers are professional, competent and willing to do whatever it takes to get the job done on time and on budget. They also do a wonderful job maintaining the spaces we buildout after a project has been completed. This takes a strong understanding of mechanical systems and the personal skills that allow for long lasting client relationships.

I searched long and hard to find someone to install my backup generator and security cameras. I was so happy to finally find Pro Mechanical! They were easy to work with and did a great job. I would definitely recommend them to anyone.

Pro Mechanical Services has been an outstanding partner for integrating our critical facility solutions. As with every museum, the MAC requires precise, high-performing climate control to preserve its treasures. But we also had a goal to reduce energy. With Pro’s full scope of capabilities, they developed solutions to meet our goals of managing climate control on a per-room basis, optimize energy savings, improve our security system and increase efficiency with an integrated solution. Pro now manages 90 percent of our service and maintenance remotely, providing the MAC continued cost savings.


I wanted to thank you for fixing our home in a fast, timely manner. My son was three days out of surgery and needed electricity for his medical devices. The electricians from Pro were fast and worked hard to reconnect our power. We learned from talking with them that they had been up all night on a previous job, and after completing the work at our house, they were off to another project. These men were polite and hard workers. I will definitely recommend your company in the future.
