Why Rooftop Units Fail Faster on the Lowcountry Coast
Sun, Salt and Storms
Rooftop units fail faster on the Lowcountry coast because they sit in full sun all day, take salt spray near the harbor and islands, and ride out tropical storm winds on the roof.
| Coastal Stress | What It Does | How We Help |
|---|---|---|
| Full sun | Heats electrical parts, wears capacitors | Test and replace weak parts |
| Salt spray | Corrodes coils and cabinets | Coil cleaning and coatings |
| Storm winds | Loosens panels, damages curbs | Post-storm inspections |
| Heavy rain | Floods drains and electrical | Drain treatment and seal checks |
