HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In this candid conversation, Nathan and Bryan dive deep into the often-misunderstood world of sales in the construction and HVAC trades. Nathan, who has transitioned from fieldwork to spending roughly 60% of his time in sales, offers a unique perspective on why sales professionals are necessary despite the skepticism they face from tradespeople. The discussion tackles head-on the negative perceptions surrounding salespeople while making a compelling case for their essential role in growing and sustaining a trades business.

The conversation explores the fundamental differences between residential and commercial sales, revealing insights that anyone in the industry will find valuable. Nathan explains that residential sales requires quick relationship-building, subject matter expertise, and the ability to emotionally connect and disconnect rapidly from customers you may only see every few years. It’s essentially retail sales with a technical component. Commercial B2B sales, on the other hand, is far less transactional and much more relational—it’s about building confidence, managing accounts effectively, and ensuring clients can focus on their core business while you handle their facility problems seamlessly.

One of the most refreshing aspects of this discussion is Nathan’s honesty about the unglamorous side of sales. He emphasizes that the job isn’t about fancy lunches or golf outings—it’s about being the person who answers their phone, follows through on commitments, and doesn’t shy away from uncomfortable conversations. The guys share frustrating examples of poor salesmanship, from ghosting potential clients to making promises that can’t be kept, illustrating how these failures give the entire profession a bad reputation. Nathan stresses that good sales is fundamentally about managing expectations, delivering on promises, and serving as the crucial liaison between customer needs and production capabilities.

The conversation concludes with practical advice for tradespeople considering a move into sales: if you’re motivated by the chase, enjoy solving people’s problems, and find satisfaction in knowing your work directly impacts the bottom line, sales might be for you. But if you’re just looking for an easier path with less physical labor, think again—great salesmanship is mentally demanding work that requires constant follow-through and resilience.
