On May 25, 2025, Reliance Heating and Air appeared on the leak site of the BlackLock ransomware group after the company’s internal files were allegedly exfiltrated during a ransomware attack. The Georgia-based HVAC contractor, which provides heating, cooling, air conditioning, heat pumps, ductless mini-splits, refrigeration, and furnace services to residential and commercial customers in the Metro Atlanta and Nashville areas, had revenue of $21.7 million last year. While the exact number of affected individuals remains unknown, any customer, employee, or vendor whose personal or financial records were stored in those systems may now have their information exposed.

What Public Reporting Shows
Public reporting indicates that BlackLock listed Reliance Heating and Air on its data-leak portal and provided a direct link to a downloadable archive hosted on the onion site. The exposed material consists of internal files exfiltrated during the ransomware incident. No precise count of records or list of specific data types has been published, but ransomware groups routinely extract customer invoices, service contracts, payment details, employee records, and contact information. The listing appeared on May 25, 2025, and the group typically sets a short deadline before releasing or selling the full archive.
Why This Matters for You and Your Family
If you or anyone in your household has done business with Reliance Heating and Air, your name, address, phone number, email, or payment information could be sitting in a zip file now circulating among criminals. That data can be used for identity theft, tax fraud, or targeted phishing emails that look legitimate because they reference your recent furnace repair or air-conditioner service. For families with children, the risk extends further: a single leaked parent email or phone number often links to family gaming accounts, school forms, or shared family calendars that give attackers a roadmap to additional personal details.
Credential leaks like this one cascade into account takeovers when the same password has been reused across multiple services. A criminal who obtains your information from an HVAC company can test those credentials on email, banking, and gaming platforms within hours.
