The three layers behind “local” home services
Private equity has built a three-layer ownership structure across residential HVAC, plumbing, and electrical. Knowing the layers is the fastest way to understand why two “local” companies can behave completely differently.
Layer 1 — The control sponsor
A private equity firm or institutional investor that owns the platform. This is where the returns flow, and where hold-period and resale decisions are made.
Layer 2 — The operating platform
A holding company that provides capital, recruiting, procurement, and acquisition support across dozens of local companies. Most homeowners never hear its name.
Layer 3 — The local brand
The name on the truck. After an acquisition it usually stays the same — same logo, same reviews, same phone number — while the ownership above it changes completely.
The 20 largest platforms, ranked
Indicative ranking from commissioned market research — most platforms are private and do not disclose comparable financials, so scale signals are based on publicly identified brand counts. Scroll the table on mobile.
The 20 largest private equity-backed residential home services platforms, their control sponsors, operating models, and publicly identified brand counts.
“Identified” counts brands named in public directories and announcements; “reported” is the platform’s own stated scale. The gap matters: the largest platform reports 107 brands while only 19 are publicly identifiable.
18 of these brands operate in Southern California
These are the publicly identified platform-owned brands serving Los Angeles, Orange, Ventura, San Diego, and the Inland Empire — names most homeowners assume are independent.

Educational Ownership Directory: Brand lists reflect publicly identified brands as of the research date — a public-information map, not a legal entity register. Platforms acquire without press releases, retire names, and combine branches. A company not listed here is not necessarily independently owned. Platform and brand relationships are based on publicly available reports and the client-supplied market map used as a proof source. Ownership structures can change over time; homeowners should confirm directly with each bidder before making a final decision. Franchise-system listings describe the franchisor network — the local franchise business is typically independently owned.
Methodology & limitations
Brand lists reflect publicly identified brands as of the research date — a public-information map, not a legal entity register. Platforms acquire without press releases, retire names, and combine branches. A company not listed here is not necessarily independently owned. Brand lists are compiled from platform brand directories, sponsor portfolio pages, and first-party transaction announcements, current through July 11, 2026. Franchise systems are listed for completeness — a franchise location is typically an independently owned business paying royalties, which is a very different structure from a platform-owned company. If you believe an entry is out of date, tell us and we will re-verify it against current sources.
