The Lowcountry’s Diagnostic Authority

Built on Integrity and Coastal Expertise

Driftmark Heating & Air was founded to bring a higher standard of technical troubleshooting to the Hilton Head and Savannah areas. We recognized that many property owners were tired of high-pressure sales and "part-swapping" technicians. Our founder established Driftmark as the "Diagnostic Authority," focusing on finding the mechanical root cause of every issue. Today, we are proud to be a family-backed company that treats every home and business like our own, specializing in systems built to survive the demanding Lowcountry climate.

FAQ

Expert Answers For Your HVAC System

  • Do you offer emergency HVAC services on weekends?

    Yes, we provide 24/7 emergency repair for both residential and commercial properties.

  • Do you provide financing for new systems?

    Yes, we partner with Wisestack to offer flexible financing options for system replacements.

  • How often should I change my air filter?

    Every 1-3 months depending on usage and pets.

  • How long does a typical AC installation take?

    Most residential installations are completed within one business day, including full HVAC system commissioning.

  • Do you service commercial units?

    Yes, we handle commercial HVAC and refrigeration (HVAC/R).

  • What are the signs I need a new AC?

    Frequent repairs, rising energy bills, and inconsistent cooling.

  • How often should I service my AC in a coastal environment?

    We recommend twice a year: once before the cooling season and once before the heating season. This helps  to remove salt buildup that dimenihes the function and lifetime of your Air Conditioning.

  • What is a "Diagnostic Authority"?

    It means we prioritize master-level troubleshooting to find the root cause of a failure rather than simply replacing parts or reccommending a total system replacement.

  • Why coastal HVAC systems fail faster?

    The Lowcountry's relentless environment presents severe mechanical challenges that do not exist inland. High heat combined with continuous salt air accelerates corrosive pitting on condenser coils and electrical components, weakening copper lines over time. Additionally, persistent coastal humidity forces systems to run longer cycles to dehumidify indoor air, doubling mechanical wear. Without specialized care, these unique coastal conditions cause premature efficiency loss and equipment failure years ahead of schedule.

  • Why is my indoor humidity so high?

    In the coastal areas like Hilton Head Island, Bluffton West, and Savannah, high indoor humidity often stems from oversized systems or air leaks. We offer dehumidification audits to find the issue and fix it.

  • Are mini-splits more efficient than central air?

    Often, yes. Because they allow for zoned cooling, you don't waste energy cooling rooms that aren't in use.

  • What are the signs of a refrigerant leak?

    Hissing sounds, ice on the coils, and a system that runs constantly without reaching the set temperature are common indicators.

  • How can I improve my indoor air quality?

    We suggest a combination of high-MERV filters and UV-C germicidal lights to kill biological contaminants.
