Get answers to common questions about hvac services in Long Key, Florida.
In Long Key, a full HVAC system replacement typically ranges from $6,000 to $15,000+, heavily influenced by system size (tonnage), efficiency rating (SEER), and the specific challenges of coastal installation. Key local factors that can increase cost include the need for corrosion-resistant components due to salt air, compliance with South Florida's strict building codes for hurricane zones, and the potential for difficult access in elevated or waterfront properties. Higher SEER systems, while more expensive upfront, are crucial for managing our intense summer heat and humidity efficiently.
The absolute best time is during our milder "shoulder seasons," specifically late fall (October-November) and early spring (February-March), before the oppressive summer heat and humidity arrive. Scheduling during these windows ensures greater availability from local technicians and often leads to faster service. Waiting until the peak summer months (June-September) often results in longer wait times for emergency repairs and higher demand pricing, as every homeowner's system is under maximum strain.
Yes, prioritizing corrosion resistance is paramount. Look for systems with coated coils (often called "coastal" or "salt-air" packages) and galvanized steel cabinets to combat the corrosive salt air that rapidly degrades standard units. Given our high humidity, a variable-speed air handler and a system with strong dehumidification capabilities are essential for comfort and preventing mold/mildew. Proper elevation of the outdoor condenser above base flood elevation (BFE) is also a critical local installation requirement.
Choose a contractor with a proven, long-term presence in the Florida Keys, as they understand the unique coastal challenges. Always verify they hold a valid Florida Certified HVAC Contractor license (not just a county certificate) and carry both liability and workers' compensation insurance. For Long Key specifically, ask for references from nearby projects and inquire directly about their experience with installing systems to meet Monroe County's strict flood zone and corrosion protection standards.
The most common local causes are a dirty or clogged air filter, blocked condenser coils from sand and salt spray debris, or a refrigerant leak exacerbated by corrosion. First, check and replace the air filter, then ensure the outdoor condenser unit is clear of vegetation, sand, and debris with at least 2-3 feet of clearance. Due to our constant operation, systems here work harder and are more prone to these issues; if simple cleaning doesn't resolve it, call a professional immediately to prevent a minor issue from becoming a major failure during peak heat.
