AC Replacement: Signs It's Time
- The compressor or outdoor coil has failed on a system older than 10 to 12 years.
- It needs refrigerant every season, which means an unrepaired leak.
- Repairs in the last two years add up to a large share of a new system's price.
- Rooms stay humid or uneven even when everything runs.
Near the coast in Myrtle Beach, South Carolina, corrosion often decides it. Salt air pits outdoor coils, and a coil that's started leaking usually isn't worth patching.
Sizing and Efficiency
A new system should be sized to the house with a load calculation, not copied from the old unit's size. An oversized AC cools fast but shuts off before it removes humidity, which matters in a humid climate like Myrtle Beach, SC.
South Carolina is in the federal Southeast efficiency region. New split air conditioners under 45,000 BTU must meet at least 14.3 SEER2 here, and new heat pumps must meet 14.3 SEER2 nationwide.
Furnace Installation and Heat Pump Options
Homes with a gas furnace or gas pack can replace it with the same type, or switch to a heat pump. Heat pumps are common in South Carolina because winters are mild. A furnace installation usually includes a new gas connection check, venting that meets the new unit's requirements, and matching the indoor coil to the new AC.

Permits and the Quote
Inside city limits, a new central AC unit, heat pump or ductwork needs a mechanical permit from the City of Myrtle Beach Construction Services Department, which issues them only to state-licensed contractors. A good quote lists model numbers for the indoor and outdoor units, the SEER2 rating, what happens to the old equipment and line set, and permit costs.
