Coastal salt air corrosion that takes five to seven years to produce significant damage on a Treasure Coast property can accomplish the same destruction in two to three years in the Keys. Equipment positioned on oceanfront or canalfront properties — especially in the Lower Keys where ocean exposure is nearly total — can show severe coil fin deterioration within 18 months of installation if not properly protected. Standard aluminum fin coils are inappropriate for many Keys installations; coated coils, copper-fin coils, or specially treated equipment are often the only configurations that achieve an acceptable service life. We assess each property's specific exposure before recommending equipment, and we apply protective coatings as a standard first step on every new outdoor unit installation. See our AC installation and maintenance services.

The Keys are connected to the mainland by a single road — US-1 — and there is no HVAC parts warehouse in Monroe County. When a component fails on a Keys system, a contractor who didn't anticipate the job correctly either leaves the homeowner without AC while they make a round trip to Miami-Dade, or they have the wrong part and make that trip anyway. Cooling Refrigeration Services loads Keys service trucks with a comprehensive inventory of the most commonly needed components before making the drive down — capacitors, contactors, run capacitors, fan motors, drain line supplies, refrigerant — so that a diagnostic visit translates into a completed repair on the same trip whenever possible.

Keys building codes require homes in flood zones to be elevated on concrete block columns or wood pilings — which means HVAC equipment placement, duct routing, and service access often look nothing like a standard residential installation. Air handlers tucked into elevated utility spaces, condenser units positioned under elevated decks or on exposed pilings, and ductwork routing through unconventional structural spaces are the norm rather than the exception in much of the Keys. We work across all of these configurations and understand the specific access and installation challenges that Keys construction presents. Learn about our Keys-specific AC services.

What type of outdoor unit holds up best in the Keys environment?

Equipment with epoxy-coated or Baked-on polymer coil coatings, stainless hardware, and corrosion-resistant cabinet construction is the minimum standard for Keys installations. Copper-fin coils offer the highest corrosion resistance for the most exposed locations. We specify the appropriate configuration based on each property's ocean proximity and exposure.

My AC unit is under my elevated home. Does that affect service access?

It affects logistics, not capability. We work with equipment in all of the configurations common to Keys elevated construction — under-structure condensers, elevated mechanical rooms, and coastal utility spaces are routine for us.

How far into the Keys do you service?

Cooling Refrigeration Services serves the full Florida Keys — from Key Largo and Islamorada through Marathon, the Lower Keys, and Key West. We make the drive because we understand that the distance doesn't excuse leaving Keys homeowners without service.

Cooling Refrigeration Services serves the Florida Keys from Key Largo to Key West with same-day availability and 24/7 emergency response. We arrive prepared. Call 863-467-4733 or request service online. We're based at P.O. Box 2218, Okeechobee, FL 34973.
