Job Description

Join a Team That Solves the Gulf Coast’s Toughest HVAC Challenges

Picture your morning: you review the day’s calls, load up your meters and tools, and head out across Sarasota, Bradenton, Lakewood Ranch, and nearby Gulf Coast communities. By noon, you’ve tuned a rooftop unit, identified a failing sensor on a VAV system, and walked a customer through performance recommendations. In the afternoon, you commission a new split system on a ground-up commercial site before updating your service notes and heading home, satisfied that everything runs safely and efficiently.

Our client is a well-established, growing commercial mechanical contractor with a service mix of roughly 75% commercial and 25% residential. They tackle a steady stream of new ground-up commercial construction projects and value professionalism, safety, and ongoing career development.

• Execute preventive maintenance on RTUs, chillers, split systems, air handlers, and package units to maximize uptime.
• Conduct thorough inspections to surface potential failures before they impact operations.
• Handle start-up, testing, balancing, and commissioning activities on new and existing installations.
• Keep precise service records and documentation that tell the full story of each call.
• Communicate findings and options clearly to customers, setting expectations and building trust.
• Work to company safety standards and comply with local codes on every task.
• Coordinate with project managers, service coordinators, and fellow techs to deliver a great customer experience.

What You Bring
