Is St Francis Heating And Air Conditioning (HVAC contractor listed at 1915 E Tripoli Ave, St Francis, WI 53235) owned by private equity?

Notes

• The primary consistent footprint for this exact name remains a directory-style listing showing 'St Francis Heating And Air Conditioning' at 1915 E Tripoli Ave, St Francis, WI 53235, but without a legal entity name, ownership, or parent/sponsor disclosure.
• Escalation to Wisconsin’s official corporate-records search could not produce a definitive entity match for this business name from the available non-interactive evidence; additionally, the Wisconsin DFI corporate records search explicitly notes it does not record sole proprietors, tradenames (DBAs), or owners, which limits its usefulness when the underlying business is a DBA/sole proprietorship.
• The address (1915 E Tripoli Ave, Saint Francis, WI 53235) is strongly associated in official/state healthcare publications with 'St Francis Health Services' (a nursing home/facility), suggesting the directory listing’s address may not correspond to an HVAC operating company legal entity (or may reflect a misattribution).
• Because an authoritative legal entity record (with officers/managers/jurisdiction trail) could not be tied to the HVAC name, ultimate ownership (including whether PE-backed) cannot be confirmed.
• The only strong, consistent public footprint found for this exact name is a directory listing showing it as a local HVAC business with a St Francis, Wisconsin address and phone number; no parent company, sponsor, or acquisition information is disclosed there.
• No official company website, portfolio page, or acquisition announcement could be located in the research that would allow confirming current controlling ownership or founding details.
• Because there is insufficient authoritative information to confirm ultimate ownership (or independence), the ownership status is marked as uncertain rather than definitively not PE-owned.
