In this episode of "HVAC Chats," Derek Aarstad, owner of DNA Heating and Cooling in Richmond, Virginia, discusses how building science, diagnostics, performance testing, and customer education have shaped his high-performance HVAC business. Aarstad explains why more than half of the comfort complaints he encounters are not actually equipment problems and how heat load calculations, Manual S, commissioning, duct leakage testing, and IAQ assessments can help contractors deliver better-performing HVAC systems. He also shares lessons on intentionally limiting company growth, attracting the right customers through organic digital channels, using AI-driven referrals, and avoiding technician and owner burnout.

In this episode of "HVAC Chats," Nicole Krawcke, editor-in-chief of Contracting Business, talks with Lauren Acosta Huckleberry, president of Acosta Heating, Cooling, and Electrical, about modernizing the HVAC sales process through online pricing and greater price transparency. Acosta Huckleberry explains how her company uses online pricing to meet changing homeowner expectations, generate leads, and provide customers with pricing information outside normal business hours. The conversation also explores how digital tools can support comfort consultants, the importance of proper HVAC system sizing, and the connection between equipment selection, home comfort, and IAQ.

"HVAC Chats" host Nicole Krawcke, head of content of Contracting Business, sits down with Chris Roth, HVAC contractor, educator, and co-owner of Quality Training Centers, to discuss how contractor-led education can reshape the industry's workforce pipeline. Roth explains why traditional trade school models often fall short of preparing technicians for real-world field performance and outlines a contractor-centric approach focused on producing hire-ready, day-one billable employees. The conversation explores practical strategies for improving workforce development, technician retention, and business growth while addressing the skilled labor shortage facing HVAC contractors.
