About Our Company

Capstone provides a relationship-driven service experience

You’ve heard the story before, you may also have a story of your own—two guys start a company in their garage because they want to change the world… passion runs deep, hard work ensues and dreams are realized. More often than not, it’s simply taking action with your intentions to “change the world” that contributes most to the outcome of your business venture. Will success be reached? Will the economy absorb your lifelong plans to achieve your dream? That’s ultimately up to you and is largely dependent upon the amount of drive, passion and hard work you commit to your dreams


Our Corporate Culture

Capstone Mechanical is a culture-focused commercial HVAC company

Our people make us who we are—their character, attitude, creativity, individuality, and their compassion drive our corporate goals, decision making and the approach we take with each new relationship we forge. We think of our customers as much more than simply “a company”—they’re real people with real needs, concerns and expectations. We treat every customer as a relationship—and we treat each relationship with courtesy, kindness, devotion and dedication. The purpose of this culture statement is to demonstrate the values we live each and every day as well as the manner in which we communicate with our customers and foster the relationships with share.
