Jacksonville HVAC FAQ
Should I cover my AC during a hurricane?
Turn it off and cut power at the breaker before the storm. Don't run it until flooding and debris are checked afterward.
Why does my Jacksonville home feel damp with the AC on?
Often an oversized system, a fan set to 'on' or leaky ducts. A technician can measure humidity and airflow.
