Why HVAC and Plumbing Businesses Trust Me With Their Technology
By Lonnie Holcomb, Founder — Kelsey-McGuire Inc.
The Problem Most Trade Businesses Don’t Know They Have
Every missed call is a missed job.
Every unsecured inbox is a liability waiting to happen.
And every hour you spend wrestling with technology is an hour you’re not running your business.
Most HVAC and plumbing companies don’t have — and don’t need — a full-time IT department.
But they still need their phones answered, their systems secure, and their technology working for them instead of against them.
That’s where I come in.
Who I Am
I’ve spent 17+ years designing, securing, and automating infrastructure for organizations where failure wasn’t an option — the U.S. Air Force, U.S. Army Reserve, Citibank, and Fortune 500 companies like Extreme Networks.
I’ve secured classified government systems, led compliance audits across global teams, and built automation that’s reduced security incidents and manual errors by as much as 80%.
In 2013, I took that same discipline and started applying it to small businesses — because trade businesses deserve enterprise-grade reliability without the enterprise-grade price tag or complexity.
What I Do
🔧 AI Phone Receptionist
Missed calls cost you jobs.
My AI-powered phone receptionist answers every call — day, night, weekends — books the appointment, and gets the details straight to you.
No more voicemail.
No more lost revenue because you were mid-job and couldn’t pick up.
📧 Secure Business Email Hosting
I design, build, and manage secure email infrastructure from the ground up — DNS configuration, TLS encryption, and spam protection — so your business communication is reliable and protected.
This isn’t outsourced to a faceless provider; it’s built and monitored by someone who’s run this exact setup for years.
🖥️ Linux Systems & Security Hardening
Behind the scenes, I handle server administration, automation, and security hardening using the same tools and standards required by the Department of Defense — Ansible, BASH automation, vulnerability scanning, and ongoing patch management — so your systems stay stable and protected without you having to think about it.
🧭 Fractional CTO Support
Growing past the point where “figure it out yourself” works, but not ready for a full-time technical hire?
I provide part-time technical leadership — systems architecture, security strategy, and automation planning — for founders and small businesses that need real expertise without full-time overhead.
Why It Matters
You didn’t get into HVAC or plumbing to become a part-time IT manager.
You got into it to run a business, serve customers, and grow.
My job is to make sure the technology behind your business is one less thing you have to worry about.
Every solution I build is backed by nearly two decades of experience keeping mission-critical systems — literally, military and financial systems — secure, compliant, and running around the clock.
That’s the same standard I bring to your business.
Let’s Talk
Whether you’re losing jobs to missed calls, worried about the security of your business email, or just tired of technology getting in the way, I can help.
