Why Choose Anchor Heating and Air?


When you call Anchor Heating and Air, you’re not just getting routine repairs; you’re getting tailored solutions for Charleston’s specific challenges. Here’s how we make a difference:

  • Refrigerant Leaks: If your system isn’t cooling consistently or you hear a hissing noise, it’s a likely sign of a refrigerant leak. Our team will locate and seal the problem while ensuring your AC runs efficiently.
  • Compressor Problems: Coastal humidity can take a toll on compressors, but we replace or repair these essential components to get your system up and running again in no time.
  • Clogged Filters: Dust and pollen build-up are no match for our thorough filter replacements, which improve both airflow and your AC’s performance.
  • Electrical Issues: Whether it’s worn-out capacitors or corroded connections from Charleston’s high humidity, we’ll get your system’s electrical components back in working order.
  • Thermostat Troubles: Struggling with an inaccurate or unresponsive thermostat? We’ll recalibrate or replace it to ensure every room in your home stays comfortably cool.
  • Drainage Hassles: Blockages in condensate drain lines can cause moisture buildup and even trigger your system to shut off. We’re here to clear it out and help prevent mold or water damage.
  • Corroded Coils: Coastal air leads to faster corrosion of evaporator and condenser coils, but don’t worry—we’ll restore efficiency and stop potential refrigerant leaks before they escalate.
