Local HVAC Service - Myrtle Beach, South Carolina
The federal minimum efficiency standards for new AC equipment changed in 2023, and they vary by region. South Carolina falls in the southern efficiency region, meaning new AC installations in Horry County must meet the 15 SEER2 minimum — not the 14 SEER2 that applies in northern states. Higher-efficiency equipment costs more upfront but reduces operating costs over the system's life. In Myrtle Beach's climate with its extended cooling season, the payback on higher SEER2 equipment comes faster than it would in a market with a shorter AC season.
In Myrtle Beach, air conditioning isn't seasonal — it's infrastructure. Horry County's climate means cooling systems run from spring through fall under conditions that simultaneously stress refrigerant circuits, blower motors, and drain systems. A system that made it through last summer isn't guaranteed to make it through the next without attention.
Myrtle Beach's extended cooling season generates approximately 2,910 cooling degree days of annual energy demand. Homes built around 1985 — the median construction year in Horry County — are at the age where original air conditioning equipment has either been replaced once or is overdue for evaluation.
