The Snowbird Home Watch AC Guide
Leaving your Florida home vacant for the hot, humid summer months carries significant risk if your HVAC system fails. Elevated indoor relative humidity (above 60%) quickly fosters mold growth, potentially causing thousands of dollars in property damage.
Our specialty Snowbird Pre-Departure Inspection includes clearing condensate lines to prevent blockages, setting programmable thermostats to vacant humidity levels (typically 78°F or humidistat settings), and installing secondary safety float switches. We also coordinate with local home-watch services to verify system status, ensuring total peace of mind while you are away.
