Get answers to common questions about hvac services in Marathon, Florida.
The salt-laden air in the Florida Keys is highly corrosive and can significantly shorten the lifespan of your outdoor AC condenser coil and other metal components. To combat this, we recommend scheduling professional maintenance twice a year (before and after peak season) to clean the coils and electrical connections, and to ensure the unit is properly sealed. Installing a protective, corrosion-resistant coating on the condenser unit is also a highly recommended local practice.
The ideal time is during our "shoulder seasons"—late fall (October-November) or early spring (February-March). Scheduling during these periods ensures better availability for technicians and parts, and you can avoid the stress of a system failure during the intense summer heat and humidity when demand for emergency repairs is highest and wait times are longest.
Yes, Marathon and Monroe County have strict building codes, including elevation requirements for outdoor units due to flood zones. All installations must comply with Florida's high-velocity hurricane zone (HVHZ) codes, which often require hurricane straps or stands. Furthermore, you must use a licensed contractor who pulls the proper permits from the county, as unpermitted work can lead to fines and issues during a property sale.
Always verify the contractor holds a valid Florida Certified HVAC Contractor license (not just a county certificate) and carries both liability and workers' compensation insurance. Choose a company with a long-standing local presence, as they understand the unique environmental challenges and can provide faster emergency service. Be wary of "storm chasers" who appear after hurricanes offering low prices but no local track record.
Given our year-round cooling needs, the most impactful upgrades are installing a high-SEER (16+) air conditioner, ensuring your ductwork is properly sealed and insulated (especially in unconditioned attics), and adding a smart thermostat to manage settings. Because of our intense sun, improving your home's overall envelope with solar window film, attic insulation, and sealing air leaks is also crucial to reduce the cooling load on your system.
