62 Florida-licensed HVAC subcontractors serve Florida Keys (Monroe County). Browse listings below, or create a free* GC account to see phone and email and invite a sub to bid on your RFQ.
Most of these HVAC subcontractors are based in Key West (19), Key Largo (11), Tavernier (8), Marathon (7), Big Pine Key (4), and Summerland Key (3) — plus 10 more across the metro.
HVAC subcontractors handle the heating, ventilation, and air conditioning systems on a project — rooftop and split-system equipment, chillers and boilers, ductwork, VAV boxes and terminal units, controls and thermostats, and exhaust and make-up air. On commercial jobs they price from the mechanical plans and HVAC spec, coordinate with electrical for power and controls and with plumbing for condensate and gas, and pull permits and schedule inspections on their portion of the work.

When a GC sends an HVAC RFQ, they're usually looking for a quote against a defined scope: the mechanical drawing set and Division 23 spec section, a clear inclusion and exclusion list (equipment, ductwork, controls, test-and-balance, start-up, commissioning), and the sub's read on long-lead items like rooftop units, chillers, and switchgear-side controls. For bid prep a GC typically wants pricing broken out enough to compare apples-to-apples, confirmation the sub priced to the spec book, and the sub's license and insurance on file.
Air conditioning contracting in Florida is a state-licensed trade, regulated by the Construction Industry Licensing Board (CILB) under the DBPR. There are two tiers: a certified air conditioning contractor (license prefix CAC) is authorized to work anywhere in the state, while a registered air conditioning contractor (RA) is limited to the local jurisdiction that issued their competency card. Florida treats unlicensed contracting as a crime, so a GC confirming a sub's active CILB license is doing basic bid-prep diligence — which is why every HVAC sub in this directory carries its DBPR license number.
Yes. Air conditioning contracting is regulated statewide by the Construction Industry Licensing Board (CILB) under the DBPR. A certified (CAC) license works anywhere in Florida; a registered (RA) license is limited to the jurisdiction that issued it.
Certified air conditioning contractors can take work anywhere in Florida. Registered air conditioning contractors can only work in the local jurisdiction that issued their competency card.
The mechanical drawing set and Division 23 spec section, a scope inclusion and exclusion list (equipment, ductwork, controls, test-and-balance, start-up), any long-lead equipment, the bid deadline, and whether a site visit is required.
Yes. GCs post an RFQ and invite matched subs by trade and service area; invited subs are notified and can submit a bid for your bid prep.
Listings are seeded from public Florida DBPR license data, and a sub can claim its listing and upload a credential for a one-time review. The badge reflects what was reviewed: a verified state license earns License Verified — the usual path for an HVAC sub — a verified certificate of insurance earns Insurance Verified, and a sub with both reviewed shows the Verified Pro umbrella.
