Northern Air Systems, a specialized commercial and industrial HVAC contractor, filed notice of a data breach with the Indiana Attorney General on July 1, 2026. This notification indicated that a security incident occurred on November 19, 2025. The specific details regarding the nature of the breach were not disclosed in the public filings.

According to the information reported, the breach resulted in the exposure of several categories of personal data. This included individuals' Full Name, Social Security Number, Date of Birth, Driver's License Number, Direct Deposit Account Details, Home Address, Personal Email Address, and Wage and Tax Information.

The compromise of such detailed personal and financial information, particularly Social Security Numbers and direct deposit details, carries a significant risk. Affected individuals could be targeted for identity theft, financial fraud, or other malicious activities.

Individuals who have received a notification from Northern Air Systems about this incident should take proactive steps to safeguard their identity and finances. It is strongly recommended to regularly review bank statements and credit card activity for any unauthorized transactions.

Monitoring credit reports from the three major bureaus (Equifax, Experian, and TransUnion) is also a critical step to detect suspicious accounts or inquiries. Consider placing a fraud alert or credit freeze on your credit files to prevent new credit from being opened in your name without your explicit approval. Additionally, be cautious of any unsolicited communications, as these could be phishing attempts seeking to exploit the exposed data.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Guard against tax fraud

    File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.

  • Watch your financial accounts

    Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.

  • Replace exposed ID documents

    Contact your state DMV or the issuing agency about replacing an exposed driver's license, passport, or government ID number.

  • Secure your online accounts

    Change the password on any account that reused an exposed password and turn on two-factor authentication wherever it's offered.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
