Replace and install new ductwork for residential and commercial properties, including new builds, adding returns, and full system replacements. Tickets range from $10,000-$15,000+. A natural progression from starting with duct cleaning, with high margins since few people want to do the work.

RV Park Consolidation and Roll-Up
Consolidate multiple small RV parks across a region under a single consumer-facing brand (like KOA) to achieve economies of scale, compress cap rates, and eventually exit to private equity at a premium. The sector is largely unconsolidated with most parks still mom-and-pop owned, creating opportunity for professional operators.
