October is Cyber Security Awareness Month, and the message is clear: the basics still matter. The “Core 4” practices continue to be the foundation of digital safety. These are:
- Spotting scams
- Using strong passwords
- Enabling multi-factor authentication (MFA)
- Keeping software updated
This week, we’re focusing on one of the most overlooked but critical practices: software updates. If your HVAC business relies on connected systems, smart controls, or cloud-based platforms (and let’s face it, most do), then keeping your software up to date is non-negotiable.
Why Updates Matter in HVAC
Think of software updates as your digital immune system. Just like your body needs vaccines to fight off new viruses, your devices and systems need regular updates to defend against evolving cyber threats.
Cyber criminals actively scan for outdated systems. According to the Ponemon Institute, nearly 60% of breaches stem from unpatched vulnerabilities. That means if your building management system (BMS), scheduling software, or even your email client hasn’t been updated, it could be the weak link that lets attackers in.
For HVAC contractors managing multiple sites, remote access tools, and smart building integrations, skipping updates doesn’t just put your business at risk, it can compromise client systems too.
AI Is Changing the Game for Better and Worse
Artificial intelligence is speeding up how updates are developed and deployed. Security vendors now use AI to:
- Detect vulnerabilities faster by scanning code
- Predict threats before they become widespread
- Automate patching to reduce exposure time
But attackers are using AI too. They’re scanning for outdated systems, building malware that adapts in real time, and launching automated attacks that can hit hundreds of businesses at once.
In this race, staying updated isn’t just good practice, it’s essential.
Common Excuses and Why They Don’t Hold Up
Still delaying updates? You’re not alone. But here’s why the usual excuses don’t stack up:
- “Updates take too long.” Most run quietly in the background or can be scheduled after hours. A breach will cost you far more time and money.
- “If it’s working, why touch it?” Functionality doesn’t equal security. Vulnerabilities are often invisible until it’s too late.
- “We’ll do it later.” The longer you wait, the more exposed you are. Hackers move fast so don’t give them a head start.
How Hackers Exploit Missed Updates
Attackers know many HVAC businesses don’t update promptly. They use bots to scan the internet for outdated systems and launch ransomware campaigns targeting businesses with weak cyber hygiene.
One unpatched laptop or smart thermostat could be all it takes to compromise your entire network. That’s especially risky if you’re managing systems across multiple buildings or providing remote support.
Best Practices for HVAC Teams
Keeping your systems secure doesn’t have to be complicated. Start with these steps:
- Enable automatic updates wherever possible
- Schedule manual updates regularly if auto-updates aren’t available
- Prioritise critical patches for operating systems, browsers, and security software
- Don’t forget mobile devices, tablets, and smart HVAC controls
- Keep an inventory of your hardware and software so nothing slips through
- Test updates in small batches if you’re concerned about compatibility
For HVAC contractors juggling multiple projects and platforms, these steps can prevent downtime and protect sensitive data.
Make Updates Part of Your Culture
Updates aren’t just an IT task, they’re a business-wide responsibility. Encourage your team to:
- Apply updates promptly when prompted
- Restart devices regularly to ensure updates take effect
- Report any issues caused by updates instead of ignoring them
When updating becomes second nature, you reduce risk and build trust with your clients, your partners, and your team.
Final Thought
Skipping updates might seem harmless, but it’s like leaving the back door unlocked. Treat software updates as your digital immune system. They’re your best defence against threats that evolve faster than ever.
