$275 flat diagnostic — the fix-it lane for OC businesses

Commercial HVAC Service & Repair in Orange County

Service, repair, and maintenance for offices, retail, restaurants, and light-commercial spaces — with the union-shop standards of our parent company, DaVinci Mechanical, and the same honest, evidence-first diagnostics we're known for in homes. No invented urgency, on your schedule.

Who this lane is built for

1
Small offices, suites & retail

Package units and split systems serving storefronts, professional suites, and strip-center spaces — diagnosed and repaired with the same evidence-first standard we bring to homes, on a schedule that respects your business hours.

2
Restaurants & food service

Comfort systems working overtime against kitchen heat load — we service the HVAC side (make-up air and hood systems referred honestly where they're beyond scope), and we show up when we say we will, because a dining room that's 85° is losing you covers.

3
Property managers & small portfolios

Per-unit documentation, honest repair-vs-replace math on aging rooftop and split equipment, and one accountable team. Multifamily buildings have their own dedicated page — see below.

4
Light commercial maintenance

The $275 clean & inspection scales to light-commercial equipment: coils, blowers, condensate, electrical, and a written condition report your records (and your landlord negotiations) can actually use.

Big project? That's DaVinci Mechanical — and we'll tell you so

Honest routing is part of the service: Scottish-Tom is the service and repair lane for light-commercial spaces. Design-build, new construction, major rooftop-unit replacements, and large mechanical projects belong with our parent company, DaVinci Mechanical — a full commercial mechanical contractor with the same union-trained crews. One call to either of us gets your job routed to the right team, plainly and without a runaround.

Frequently asked questions

What does a commercial diagnostic cost?

$275 flat for commercial and light-commercial service calls — a real diagnostic with findings shown and explained, credited toward the repair if you approve the work. Residential calls are $175.

What's the difference between Scottish-Tom and DaVinci Mechanical for commercial work?

Scottish-Tom handles service, repair, and maintenance for light-commercial spaces — the fix-it lane. Our parent company, DaVinci Mechanical, is the full commercial mechanical contractor: design-build, new construction, major RTU replacements, and large projects. Same union-trained standards either way; we'll route you honestly to whichever your job actually needs.

Do you offer maintenance agreements for businesses?

Yes — scheduled clean & inspection visits with written condition reports, sized to your equipment count. It's the same no-upsell model as our residential plan: real maintenance, honest findings, predictable costs.

Can you work around business hours?

That's the norm for commercial service — early, late, and coordinated with your operations. Tell us the constraints when you book and we'll plan around them.
