HVAC Field Service Representative-Technical Advisor VRF & Diagnostics

Wittichen Supply

Job Description

Wittichen Supply Company is seeking a highly skilled HVAC Field Service Representative to serve as a technical expert and trusted advisor to our contractor network.

This is a specialized role focused on advanced troubleshooting, VRF systems, and technical support — not routine service work. You will work directly with contractors and manufacturers to solve complex issues, support product adoption, and improve jobsite performance.

What You’ll Do

Technical Troubleshooting & Field Support

Provide expert phone and on-site support for complex HVAC issues
Diagnose and resolve advanced system problems across residential and commercial equipment
Assist with VRF system commissioning and advanced diagnostics (Fujitsu focus)
Serve as the go-to expert for key product lines including Rheem, Fujitsu, Copeland, and others

Manufacturer & Warranty Liaison

Act as the primary link between contractors and manufacturer technical teams
Support warranty questions and non-standard issue resolution
Maintain strong relationships with manufacturers through training and certifications

Contractor Education & Sales Support

Lead training sessions for contractors and internal teams
Educate on installation best practices and advanced product usage
Support the sales team by removing technical barriers and driving adoption of complex equipment

What We’re Looking For

3+ years of experience in HVAC service, technical support, or training
Strong technical knowledge of HVAC systems:
- Residential and commercial systems
- Heat pumps and packaged units
REQUIRED: Experience with VRF / ductless systems (commissioning + diagnostics)
Ability to troubleshoot complex systems independently
Strong communication skills — able to explain technical issues clearly
Valid driver’s license and ability to travel throughout North Alabama

Compensation & Benefits

Competitive pay (based on experience)
Company vehicle, gas, and expenses covered
Company phone provided
Opportunity to work in a high-level technical role with industry leaders

Why Join Wittichen Supply

Established HVAC distributor with a strong industry reputation
Work directly with top manufacturers and advanced equipment
Step into a less physical, more technical advisory role
Be a key partner to contractors — not just a supplier
