Always Do The Right Thing.


Since our company inception in 1987, our core values haven’t changed. We still place the highest priority on honesty, integrity and respect for our customers and employees.

  • Deliver Value

    Cost is one thing, usually driven by materials and design complexity. Value is the extra level that comes from dedication, hard work, and an emphasis on customer satisfaction.

  • A Culture of Caring

    Just doing the work isn’t enough at Pacific Rim. We sincerely care that our customers get the quality job they expect. And we care that our employees enjoy their work and are rewarded for a job well done.

  • Priority on Partnership

    When you engage Pacific Rim, we become your partner. We help you achieve your goals. We work with you to find creative solutions. We utilize the latest tools and technology.

  • Spirit of Commitment

    We have grown to become the largest open shop mechanical firm in California, while maintaining the feel of a family working together as friends. We are committed to carrying our core values into the future.
