Commercial mechanical contractor

We set the unit,
run the duct,
and stand behind it.

TL Mechanical Inc is an owner-operated commercial mechanical contractor working across Mississippi, Louisiana, and Alabama. Rooftop equipment, sheet metal, and full changeouts — self-performed.

What we self-perform

Three things, done every week.

01

Commercial HVAC

Rooftop units, split and packaged systems, and the controls that run them — diagnosed, repaired, and maintained for commercial and light-industrial facilities.

  • Rooftop and packaged unit service
  • Split system repair and troubleshooting
  • Controls and thermostat integration
  • Preventive maintenance agreements
02

Ductwork & sheet metal

Distribution is where most commercial systems actually fail. We lay out, build, and install duct that matches the equipment it is attached to.

  • Duct layout and sizing
  • Sheet metal fabrication and install
  • Retrofit and replacement of failed runs
  • Grilles, registers, and balancing support
03

Install & replacement

Full equipment changeouts and new-construction installs, scheduled around the building staying open where that is what the job requires.

  • Equipment changeouts and curb adapters
  • New construction and build-out
  • Phased replacement on occupied sites
  • Startup, commissioning, and turnover

Where we work

Three states, one crew.

TL Mechanical is based in South Mississippi and works across Mississippi, Louisiana, and Alabama. Travel outside the region is considered on a project basis.

Licensed in all three states — not working under someone else's number out of state.

Multi-site operators get one point of contact across all three states rather than a different contractor at every address.

Company

Owner-operated.

TL Mechanical Inc works out of South Mississippi. The person who quotes the job is on the job.

We work with general contractors, facility managers, and building owners. Insurance certificates, W-9s, and licensing documentation are available on request for bid packages and vendor onboarding.

Scope runs from a single equipment changeout to a full mechanical package on a build-out. If it's outside what we self-perform, we say so up front rather than learn it on site.
