This is an immediate hiring need for a hands‑on service professional with proven commercial HVAC experience, strong electrical and mechanical troubleshooting skills, and the ability to handle service calls with minimal supervision.

• Identify equipment failures, recommend appropriate repairs, and communicate findings clearly to customers.
• Accurately document service work, equipment conditions, and recommended follow‑up repairs.
• Communicate professionally with customers, dispatch, supervisors, and office personnel.
• Follow all safety procedures and maintain high standards of workmanship.

• Strong electrical and mechanical diagnostic skills.
• Ability to read and interpret electrical wiring diagrams and equipment schematics.
• Hands‑on experience diagnosing equipment failures and replacing compressors, motors, and other HVAC components.
• Ability to service commercial HVAC equipment independently and manage service calls with minimal supervision.
• Strong communication, customer service, and problem‑solving skills.
• Ability to work independently while collaborating with other technicians when needed.
• Valid driver's license and ability to travel to customer locations.
• Ability to reliably commute to Corona, CA, or relocate before starting work.

Who We're Looking For

We need a true commercial HVAC service technician who is ready to work now. The right candidate has real-world experience troubleshooting and repairing commercial equipment, understands electrical and mechanical systems, and can step into the field with confidence. Candidates whose experience is limited to residential HVAC, as well as students or entry‑level applicants looking for their first HVAC job, are not the fit for this position. If you have strong commercial service experience and are ready for your next opportunity, we want to hear from you.
