Who Is This For
Who We Support
Bridging the Gap in HVACR In an industry that is evolving faster than ever, the gap between basic knowledge and field mastery is widening. Don Gillis provides specialized, real-world training tailored to every level of the HVACR ecosystem. Whether you are in the field, behind the counter, or manufacturing the equipment, our programs are designed to build confidence, reduce errors, and drive performance.
1. HVAC Contractors & Service Teams
The Focus: Operational Excellence and Profitability.
For business owners and service managers, the greatest risks are costly call-backs and technician burnout. We help contractors transform their service departments into high-efficiency teams.
Reduced Liability: Training on A2L refrigerants and CO2 systems ensures your team operates safely and stays compliant with new regulations.
Increased Retention: Technicians stay where they feel invested in. Our training provides the professional development that keeps your best talent from leaving.
Better Decision Making: We teach your teams to diagnose the root cause, not just the symptom, saving your company thousands in “parts-cannon” troubleshooting.
2. Technicians & Field Personnel
The Focus: Technical Mastery and On-the-Job Confidence.
Theory is good, but the field is different. This training is built by a technician, for technicians. We move past the textbook to tackle the systems you face every day.
Advanced Troubleshooting: Master complex inverter-driven mini-splits, geothermal systems, and transcritical CO2 architectures.
The Fundamentals, Refined: Deep dives into airflow, refrigeration cycles, and system optimization to make you the most capable person on any job site.
Future-Proofing: Get ahead of the industry shift. Gain hands-on understanding of the next generation of HVACR technologies before they become a problem in the field.
3. Counter Sales & Distributor Teams
The Focus: Technical Literacy and Customer Trust.
The counter is the heartbeat of the industry. When counter pros understand the technical side of the parts they sell, the entire supply chain wins.
Error Reduction: Learn to ask the right technical questions to ensure the technician gets the right part the first time.
Consultative Selling: Move beyond taking orders. Become a technical resource for your customers, building long-term loyalty and increasing sales through expertise.
Product Knowledge: Specialized training on how different components interact within a system, from compressors to complex controls.
4. Technical Support Staff
The Focus: Clarity and Efficient Problem Resolution.
Internal support teams are often the last line of defense. We sharpen the communication and diagnostic skills of your support staff to resolve field issues faster.
Bridging the Communication Gap: We provide the “language” to help support staff talk through complex repairs with field technicians effectively.
Systemic Thinking: Training focused on identifying patterns in equipment failure to help support teams provide more accurate guidance.
Soft Skills Integration: Improving the tone and interaction quality to maintain high satisfaction levels during high-stress technical failures.
5. OEM Partners
The Focus: Field Adoption and Brand Reputation.
Your equipment is only as good as the people installing and servicing it. We partner with manufacturers to ensure their latest technologies are successfully integrated into the market.
Customized Curriculum: We develop training specific to your proprietary systems—whether it’s new refrigerant transitions or advanced electronics.
Market Education: Help your customers understand the why behind your engineering, leading to fewer warranty claims and better equipment performance.
National Reach: Leveraging 33 years of industry connections to deliver training that resonates with the workforce
