Search funds — the entrepreneurship-through-acquisition model that has searchers raising capital to buy and operate a single business — are discovering what PE firms already know: HVAC is one of the best acquisition verticals in the lower middle market.
But the search fund approach to HVAC is fundamentally different from the PE playbook. Here's how searchers should think about the opportunity.
Why HVAC Fits the Search Fund Model
The classic search fund criteria are well-documented: recurring revenue, non-cyclical demand, fragmented market, low technology risk, and a business that can be managed by a capable generalist. HVAC checks every box.
Recurring revenue: Maintenance plans and service agreements generate monthly cash flow. The best operators in our database show signals of established maintenance programs — a positive indicator that typically correlates with 25-40% recurring revenue.
Non-cyclical demand: When it's 102°F in Phoenix or 95°F in Atlanta, nobody defers an AC repair. Our data covers 2,300+ operators across 46 states, and the scoring patterns confirm that climate-driven markets produce the most consistent demand profiles.
Fragmented market: Of the operators we track, the vast majority are single-location independents — exactly the size and structure that search funds target. These are $1-5M revenue businesses with owner-operators who are often ready to exit.
Low technology risk: HVAC technology evolves gradually. Heat pumps, smart thermostats, and refrigerant transitions happen on 5-10 year cycles, giving operators time to adapt. There's no AI disruption coming for the person who crawls into your attic to replace a compressor.
Manageable complexity: An MBA with operational aptitude can learn the HVAC business in 90 days. The hard part isn't understanding the trade — it's finding the right company to buy.
The Search Fund HVAC Playbook
Step 1: Define Your Geography
Search funds typically want to operate the business themselves, which means geography matters more than it does for PE. You need to live where the business is.
Our data suggests focusing on states with 25+ tracked operators and strong climate-driven demand:
- Southeast: Florida (43), Georgia (49), Alabama (46), South Carolina (36), Tennessee (32)
- Sun Belt: Texas (26), Arizona (27), Louisiana (35)
- Mid-Atlantic: Virginia (35), Maryland (29), North Carolina (31)
These states offer deep target pools with year-round demand — critical for a searcher who needs to find a deal within an 18-24 month timeline.
Step 2: Size Your Target
Search funds typically target businesses with $1-5M in revenue and $300K-$1.5M in EBITDA. In HVAC, this translates to:
- 5-20 employees (technicians + office staff)
- 1-2 locations with a focused service area
- $500K-$2M in annual equipment sales plus service revenue
- Established 10+ years with a stable customer base
Our scoring model identifies these operators through size signals — location count, service area breadth, and employee estimates — without requiring financial disclosure.
Step 3: Evaluate the Owner's Situation
This is where signal intelligence provides the most leverage for searchers. Traditional search involves cold-calling 200+ owners to find the 5-10 who are receptive. Signal-based screening can help prioritize:
Higher likelihood of receptivity:
- Long tenure (20+ years in business) with no visible succession plan
- Declining website activity or neglect signals
- Owner-operated with no management team depth
- Service area that hasn't expanded in years
Lower likelihood of receptivity:
- Recently hired, actively expanding
- Strong digital presence with fresh content
- Visible next-generation involvement
- PE-backed or recently acquired
Our fit scores and acquisition interest scores capture these dynamics, helping searchers focus their outreach on the most promising targets.
Step 4: Structure the Deal
Search fund HVAC acquisitions typically structure as:
- Purchase price: 3-5x EBITDA (lower than PE because of size and key-person risk)
- Seller financing: 20-30% of the purchase price, aligning the seller's interests with a transition period
- SBA 7(a) lending: Commonly used for HVAC acquisitions under $5M, with favorable terms for owner-operators
- Search fund equity: Investor capital covering the remainder
The total deal size for a typical search fund HVAC acquisition: $1.5-5M all-in, funded with a mix of SBA debt, seller notes, and investor equity.
Step 5: Operate and Grow
The post-acquisition playbook for search fund operators in HVAC:
- Retain the existing team — technicians are the business
- Professionalize operations — CRM, scheduling software, automated dispatch
- Grow maintenance plan revenue — the single highest-impact lever
- Invest in marketing — most HVAC operators under-spend on digital marketing by 50-80%
- Consider adjacent services — plumbing and electrical add revenue per customer without adding overhead
Why Search Funds Win in HVAC
PE firms are aggressive in HVAC, but they have a blind spot: they don't want sub-$2M revenue businesses. The transaction costs don't justify it at PE scale. This means the $1-3M revenue tier — exactly where search funds operate — has less competition and more willing sellers.
Owners of these smaller shops often prefer selling to an individual operator who will maintain the company culture and take care of long-tenured employees. The search fund story — "I'm going to run this business and be here every day" — resonates in a way that "we're a PE-backed platform" does not.
