CAC1820825
Certified Air Conditioning Contractor
What this class typically covers
Typically may contract for air-conditioning installation, service, and related HVAC work within the certified air-conditioning classification (class A/B distinctions may apply on the board record).
Good to know: Confirm equipment sizing, permits, and whether refrigerant handling is performed by qualified personnel.
Board discipline from Florida extracts linked to this contractor. Separate from insurance, permits, or reviews — factual records only.
No discipline records identified in current extracts
Our Florida board discipline files do not currently attach an action to this profile. That is not a certificate of clean history: records may exist outside these extracts, under another name, or after our last load. Re-check the official DBPR board before hiring.
What this means: absence in our extract ≠ cleared. Worth confirming on the official source the day you hire.

Why workers' comp matters (Florida)
If a contractor is required to carry workers' compensation and does not, you may face liability and project risk if a worker is injured on your job. Requirements depend on structure, employees, and exemptions — the Division of Workers' Compensation is the authority. Homeowner should confirm with carrier and official portals.

Public permit/work records linked to this contractor license by an exact license-number match. A permit record is not an endorsement, and more or fewer permits on file is not a quality signal. Where we cover
No confirmed public permit records are currently linked to this license
This is not a finding that the contractor has performed no work, and it is not a finding about license standing. Coverage is currently limited to Miami-Dade County, FL building permits with an exact contractor-license match on the permit record — a contractor may have permit history outside this coverage, or the source may not have published a matching record.
