First, check your thermostat settings and the circuit breaker. If the system is unresponsive, a licensed technician can typically dispatch from near the Garden City Pier and reach most homes via US-17 Business in 10-15 minutes. A common emergency is a failed capacitor, which is a quick, on-site repair to restore cooling.

An Ecobee E1 alert indicates the thermostat has lost communication with your HVAC equipment. In Garden City, this is often caused by a tripped safety switch on the condensate drain line—a frequent issue in our high humidity. It can also signal a failed control board or a wiring issue. This alert prevents system operation to avoid damage, requiring a professional diagnosis.

The average HVAC unit for a Garden City home built in 1991 is now 35 years old, well past its 12-15 year design life. Age-related failures are common, but coastal systems face accelerated decline from salt-air induced corrosion of the condenser coil. This corrosion creates refrigerant leaks and reduces heat transfer, forcing the compressor to work harder until it fails.

HVAC systems are engineered to a specific design temperature, which for Garden City is 92°F. When ambient temperatures exceed this, the system's capacity drops. The new R-454B refrigerant has favorable thermodynamic properties for heat rejection, but any unit will run continuously on days above its design limit, which is normal operation to maintain indoor temperature.

For Garden City's mild winters, a modern heat pump is a highly efficient replacement for electric resistance heat. It provides both cooling and heating using far less energy. To maximize savings, pair it with a thermostat that avoids operation during Santee Cooper's peak hours (1-7 PM), as the heat pump's efficiency decreases slightly during the coldest parts of those periods.

All HVAC replacements in Horry County require a permit from the Planning and Zoning Department. Since January 2023, new systems must use lower-GWP A2L refrigerants like R-454B. These are mildly flammable, so 2026 codes mandate specific leak detectors, updated electrical classifications, and technician certification. Proper permitting ensures the installation meets these updated safety standards.

Flexible insulated ducts common in Garden City homes have a higher static pressure drop than rigid metal. While a MERV-13 filter is excellent for April pollen and ozone-related particulates, it may overload an older blower motor. A technician should measure static pressure to ensure your system can move enough air; a duct modification or a dedicated air purifier may be a better solution.

Yes, the current 14.3 SEER2 minimum standard represents a significant efficiency jump over units from the 1990s. With Garden City's electric rate at $0.14/kWh, a modern system can cut cooling costs by 30-40%. The active Inflation Reduction Act rebates, with an $8,000 cap, can offset a major portion of the upgrade cost, improving the return on investment.
