info_outline“Inspect your marketing the way you’d inspect a home—run diagnostics, don’t guess.” – Aaron Husak
“Attitude is way more important than aptitude. One bad apple really can infect the whole company.” – Aaron Husak
In this episode of the Building HVAC Science podcast, Eric and Bill sit down with long-time friend and contractor-turned-marketing pro, Aaron Husak. Aaron traces his winding path from solar in the mid-2000s to building performance and BPI training, and then to founding Balanced Comfort in Fresno, CA. What started as a small HERS and energy-audit firm bootstrapped its way into insulation, HVAC, and weatherization, eventually landing on the Inc. 5000 list four times and scaling from $1.3M to over $12M in just a few years. Along the way, Aaron learned the complex realities of rapid growth: hiring quickly, depending on rebate programs, uncovering serious gaps in back-office accounting and HR, and navigating California’s legal landscape. Things got especially rough when PG&E abruptly pulled a weatherization program that made up half of their revenue, right as Aaron was also dealing with the personal loss of both his parents. A rescue buyer ultimately acquired the company in early 2025, giving Aaron a hard-earned exit.
From that experience, Aaron pulls out lessons for contractors who want to grow without blowing themselves up. He emphasizes perseverance, but also warns that good field tech screening doesn’t automatically translate into good screening for accountants, HR, and support staff. He talks about the cost of keeping the wrong people too long, the importance of outside eyes on your books and compliance, and why attitude beats aptitude when building a healthy culture. He also calls out how easy it is to underestimate the impact of programs, receivables, and legal exposure—especially in states where “it doesn’t matter if you’re right, you still have to pay the attorney.”
Today, Aaron has pivoted into his next chapter with Sequoia GEO, a marketing firm focused on contractors and local service businesses, with a special emphasis on AI and “GEO” (Generative Engine Optimization). He explains why your Google Business Profile is the low-hanging fruit almost everyone neglects, how AI tools and devices like Plaud can turn field conversations into high-value website content, and why AI “likes structure” (bullets, lists, and real stories). The episode closes with practical advice: inspect your marketing like you would inspect a home, use affordable diagnostic tools to see what’s really happening online, stay transparent with customers about recording and privacy, and treat expensive mistakes as lessons that tighten your processes for the future.
