A new air conditioner is a big purchase, and on the Grand Strand it has a big job: cooling through long, humid summers while standing up to salt air. Dependable Service Plumbing & Air handles AC installation in Myrtle Beach, Pawleys Island and across the coast, from choosing the right size and efficiency to installation day.
Call us today at (843) 353-0461 to schedule AC installation or replacement, or contact us online.
Replacement often makes sense when a system is older and needs frequent repairs, when a major part like the compressor fails on an aging unit, when salt corrosion has damaged the outdoor coil, or when the house never feels comfortable or dry. If you’re not sure, start with an AC repair visit and we’ll tell you honestly whether repair or replacement is the better value.
The right size for your home isn’t based on square footage alone, and it isn’t always the same size as the old unit. We base sizing on a load calculation, which looks at how much heat your home gains and loses. It considers things like:
Sizing matters even more in a humid climate. An oversized system cools the air quickly and shuts off before it has removed much moisture, leaving the house cold and clammy. It also turns on and off more often, which adds wear. An undersized system runs constantly and may not keep up on the hottest afternoons. A correctly sized system runs long enough to dehumidify and keep temperatures steady.
SEER2 is the rating that tells you how efficiently an air conditioner cools over a typical season. The higher the number, the less electricity it uses to do the same amount of cooling. The “2” refers to an updated testing standard that better reflects how systems perform with real-world ductwork, so SEER2 numbers look a bit lower than older SEER numbers for similar equipment.
Because cooling season is long here, higher efficiency can pay back more on the coast than in cooler places. But the highest rating isn’t the right choice for every home or budget. Variable-speed and two-stage systems also run at lower speeds for longer stretches, which helps with humidity control and comfort. We’ll walk through a few options and what each means for comfort and operating cost, so you can choose with clear information.
Salt air is hard on outdoor units. If you live near the ocean, the inlet or the marsh, ask about:
We install Ruud equipment and Mitsubishi ductless systems. If your home has rooms the central system doesn’t reach well, such as a bonus room or sunroom, a ductless mini-split may be worth a look. If you’re also thinking about heating, compare a central AC with a heat pump installation, which handles both heating and cooling and is very common in our mild winters.
A new system can only perform as well as the ducts that carry its air. Leaky, crushed or poorly sized ducts in a hot attic waste cooling and can leave some rooms uncomfortable. During your estimate, we look at the ductwork and the indoor air handler and tell you if anything should be repaired or replaced along with the new equipment. Ask about duct cleaning and indoor air quality upgrades, too.
Financing is available for qualified homeowners. Visit our financing page or ask during your estimate to learn more.
Every home is different, but most installations follow the same general steps:

Not always. Your home may have changed since the original system was installed, and the original may not have been sized correctly. A load calculation gives a more reliable answer.
It can be, especially with our long cooling season. The right choice depends on your home, how long you plan to stay, and your budget. We’ll explain the trade-offs.
