Senior Commercial HVAC Service Technician
The Opportunity
Homestead Service Partners is hiring a Senior Commercial HVAC Service Technician to serve as the lead technical voice in one of our Chicagoland portfolio companies. This is the “problem solver” role — the person the team calls when something’s complex, the customer calls when something’s critical, and the GM leans on when technical decisions need to be made.
You’ll handle the toughest diagnostics, mentor junior technicians, help build SOPs from tribal knowledge, and play a direct role in quoting and scoping work accurately. This isn’t just a higher-paid tech position — it’s a leadership seat on the service team with real influence over how the operation runs.
Homestead acquires commercial HVAC companies and keeps them. We protect the teams, invest in better tools, and build systems so the company doesn’t depend on one person to solve every problem. You’ll help us build that redundancy — by sharing what you know and developing the next generation of skilled technicians.
What You’ll Do
- Lead Complex Diagnostics: Handle the hardest service calls — the ones that stump other techs. Diagnose intermittent failures, controls issues, refrigerant circuit problems, and multi-system interactions on commercial equipment.
- Mentor Junior Technicians: Ride along with less experienced techs, coach them through troubleshooting sequences, and help build their diagnostic confidence. You’re the person who turns good technicians into great ones.
- Quote & Scope Work: Accurately assess repair vs. replace decisions. Provide detailed, honest estimates to the GM and customers. Your technical credibility is the foundation for the company’s pricing integrity.
- Build SOPs from Tribal Knowledge: Work with the GM to document the “how we do things here” into repeatable playbooks — call handling, diagnostic workflows, PM checklists, parts markup guidelines. You’ll help turn what’s in your head into a system anyone can follow.
- Manage Key Customer Relationships: Serve as the primary technical contact for the company’s top 20–30 accounts. Build trust with facility managers and building owners through competence, communication, and follow-through.
- Execute High-Priority Service: Handle emergency calls for the company’s most important accounts. Meet SLA commitments, communicate status clearly, and resolve issues under pressure.
- Support Technology Implementation: Help the GM evaluate and integrate new field service management software. Provide field-level feedback on what works and what doesn’t, and help train the team on new digital workflows.
- Maintain Safety Standards: Set the example for safety on the team. Ensure PPE compliance, lead safety discussions, and report near-misses. A 98% PPE compliance target and zero lost-time incidents are non-negotiable.
How This Role Is Different
Service Tech
Executes work orders, follows PM checklists, reports findings, communicates with dispatch.
Senior Service Tech
Diagnoses what others can’t, mentors the team, scopes and quotes work, manages key accounts, and helps build the systems the company runs on.
Who You Are
- 5+ years of hands-on experience servicing commercial HVAC equipment — with a track record of solving complex problems that other techs escalate to you.
- EPA Universal Certification — required.
- Deep diagnostic ability across electrical, mechanical, controls, and refrigerant systems. You read schematics like a second language.
- Experience with building automation systems (BMS/DDC controls) — Tridium Niagara, Honeywell, Johnson Controls, Siemens, or similar.
- Comfortable quoting and scoping work. You understand the difference between a $2,000 repair and a $20,000 replacement — and you can explain why to a customer.
- A natural teacher. You enjoy helping less experienced techs level up, and you do it with patience and clarity — not ego.
- Professional, reliable, and trusted by customers. Facility managers request you by name.
- Valid driver’s license with a clean driving record.
Preferred Qualifications
- NATE certification and/or manufacturer-specific training (Carrier, Trane, Lennox, Daikin, York).
- Experience working on chillers, VRF/VRV systems, cooling towers, and process cooling — not just rooftop units.
- Familiarity with commercial refrigeration and ASHRAE standards.
- Experience with field service management software — ServiceTitan, BuildOps, ServiceTrade, or similar.
- OSHA 10 or OSHA 30 certification.
- Journeyman or Master HVAC license (Illinois).
- Experience in a post-acquisition environment or familiarity with how service companies professionalize operations after ownership transitions.
Compensation & Benefits
Compensation reflects the seniority and scope of this role. Base salary is calibrated to your experience, certifications, and demonstrated expertise. Overtime is paid at time-and-a-half. You’ll receive a company vehicle (take-home truck), health insurance, and investment in your continued training and certification. Strong performers have a clear path to leadership within the Homestead portfolio.
