Get answers to common questions about hvac services in Key Largo, Florida.
The high salt content in the coastal air is highly corrosive and can significantly shorten the lifespan of your outdoor condenser unit's coils and electrical components. Combined with our relentless humidity promoting mold and algae growth, it's crucial to have a professional perform bi-annual maintenance that includes a thorough coil cleaning with a non-corrosive solution, checking for corrosion, and ensuring the condensate drain line is clear to prevent water damage and system shutdowns.
The optimal time is during our mild "winter" months, typically from late October through February. Demand for emergency repairs is lowest during this period, allowing for more flexible scheduling and often better pricing from local contractors. Waiting until late spring or summer, when systems fail under full load, often leads to longer wait times and premium rates during the peak season crunch.
Absolutely. Given our year-round cooling needs, prioritize a system with a high SEER2 rating (16+ is excellent) and a variable-speed compressor for enhanced dehumidification and efficiency. A properly sized, energy-recovery ventilator (ERV) can also be a wise investment to manage indoor humidity while introducing fresh air without sacrificing efficiency, which is vital for our sealed, modern homes.
Verify they are Florida licensed (CMC or CCC license) and insured, and specifically ask about their experience with salt-air corrosion and the high-humidity environment of the Keys. A reputable local provider will emphasize proper system sizing (using Manual J calculations, not rule-of-thumb) to handle the latent heat load and will offer proactive maintenance plans tailored to combat corrosion and biological growth.
First, check and clean or replace your air filter, as a clogged filter restricts airflow, the system's ability to remove humidity, and causes freezing. Next, visually inspect the outdoor condenser unit to ensure it's not obstructed by vegetation or debris and that the fins are not visibly corroded or bent. Also, ensure the condensate drain line (typically a PVC pipe near the indoor air handler) is not clogged, as a blocked drain will trigger a safety switch that shuts the system down.
