Why it matters to you
Long, gentle runtimes are exactly what pulls moisture out of Lowcountry air, so inverter systems tend to fix the cool-but-sticky complaint that single-stage systems leave behind.
Practical guidance
If humidity is your main comfort problem, ask for an inverter option in your quote alongside a single-stage price. Expect the system to run almost continuously at low speed on mild days; that is normal, not a fault.
