The legend behind Scottish-Tom Heating & Air

Meet Tom Walsh — “Scottish-Tom” — the HVAC wizard who’s been keeping Orange County comfortable for over 15 years. You might know him from DaVinci Mechanical; now he’s bringing that commercial-grade precision to homes.

Why “Scottish-Tom”?

The nickname fits the mindset: stubborn about quality, careful with your budget, and tough enough for the hottest attics in OC. Most importantly, he explains your system in plain English — not HVAC hieroglyphics.

Tom Walsh — Scottish-Tom
“No upsell. No jargon. Fix what’s broken, maintain what matters, and teach you enough that every decision feels easy.”

The Scottish-Tom Difference

What you can expect on every job — from first call to final clean-up.

  • Test, measure, diagnose, and design — we find the cause of the problem.
  • 15 years’ experience; journeyman certified (local/state/national). Ongoing technical & safety training for every tech.
  • We find rebates, tax credits, and incentives — no intimidating, high-pressure sales tactics.
  • Friendly, chatty, transparent. We educate homeowners and build long-term relationships.
  • We believe if you cut too many corners, you’ll go around in circles.
  • We help our community and worthy charities (like Mercy House) — and loop in business contacts when needed.
On the job — clean, organized installs

From commercial giant to residential hero

After years handling the big stuff — malls, offices, industrial — Tom shifted to helping homeowners one-on-one. Same obsession with doing it right; now with personal attention.

What makes us different (no-BS approach)

You won’t be pitched a new system if a bona-fide repair and tune-up will do. Expect clear options, transparent pricing, and clean workmanship you’ll want to show off.
