Why Us
The perfect climate solution for Charleston’s weather
Charleston’s climate presents unique challenges—hot, humid summers and mild but occasionally chilly winters. This variable weather pattern makes heat pumps the ideal HVAC solution for local homes. Unlike separate heating and cooling systems, heat pumps efficiently handle both seasons with a single unit, providing cost-effective comfort year-round.

“After years of struggling with an inefficient electric furnace and separate AC unit, we switched to a heat pump system installed by Blanton & Sons. The difference is remarkable—our Ravenel home stays comfortable year-round, and our winter electric bills dropped by almost 40% compared to our old system. It’s the best home improvement decision we’ve made.”

When your Charleston heat pump needs professional repair
Poor Heating or Cooling Performance
When your heat pump struggles to maintain temperature in either mode, runs constantly, or produces inadequate heating or cooling, immediate repair prevents further damage.
Strange Operating Noises
Grinding, squealing, or clicking sounds during operation indicate mechanical problems that will cause expensive component failures if not repaired quickly.
Ice Formation Problems
Excessive ice buildup on outdoor units or ice that doesn’t defrost properly indicates defrost control issues, refrigerant problems, or airflow restrictions needing repair.
Frequent Mode Switching
Heat pumps that switch between heating and cooling unexpectedly or struggle to maintain selected modes have reversing valve or control system problems requiring attention.
High Energy Bills
Sudden increases in electricity costs often indicate heat pump efficiency problems from refrigerant leaks, dirty coils, or failing components that need professional repair.
