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
