Builder Systems in New Johns Island Subdivisions
Humidity First
Johns Island's population grew about 50% from 2000 to 2010, and new subdivisions keep going up. Builder systems in those homes are often single-stage units that cool fine but leave the house damp.
- Sticky house at 74 degrees: often oversized, short cycling.
- Upstairs warmer: returns too small for two floors.
- High bills in year one: ducts leaking into the attic.
Should I Upgrade a Builder System Right Away?
Usually not. Tune it, fix the ducts and balance the airflow first. Upgrade when it fails or if humidity stays high after the fixes.

Why Do Johns Island Heat Pumps Fail After Summer Storms?
Lightning and Surges
Johns Island heat pumps often fail after summer storms because lightning and power surges fry control boards, capacitors and compressor contactors. Open land and long power runs make it worse.
| Surge Damage | Typical Repair Price |
|---|---|
| Capacitor | $150-$350+ |
| Contactor | $150-$350+ |
| Defrost or control board | $400-$900+ |
| Surge protector added | $250-$450+ |
Is a Surge Protector Worth It on Johns Island?
Usually, yes. A $250-$450+ surge protector is cheap next to a $900 board or a compressor.
