Commercial HVAC

Are you searching for commercial HVAC companies on Florida's west coast that you can rely on to get the job done? Must workers be drug-tested and background checked in order to gain clearance to your building or construction site? Want a company that can also provide standby generators, plumbing, electrical, boiler service, and building automation? Call United Mechanical, LLC. We can help!

Mechanical contractors you can trust

If you've ever been burned by an unreliable contractor, you know how important it is to choose wisely. Incompetent, undependable, workers cost time and money. Plus, the comfort of you, your employees, and those you serve, suffers. And if you manage a building where workers must be credentialed to gain entry, no doubt you need a team you can depend on.


Our clients know that our team members are randomly drug tested, background checked, and must maintain clean driving records. Rest assured that you can count on us when:

  • Your hospital's air conditioning has failed and patients are at risk of hyperthermia.

  • The government building you manage requires credentialed workers.

  • The security lighting in your parking lot has failed.

  • Your school's plumbing system is backed up.
