AC Installation in Myrtle Beach, SC

A new AC is the biggest comfort purchase most homeowners make. We size it with a Manual J load calculation — never square-footage guesswork — and install it to code, permitted and commissioned.

  • Manual J load calculation on every replacement
  • Matched indoor + outdoor SEER2 equipment
  • Permits pulled and equipment registered
How it works

What happens during an AC installation visit

1. In-home assessment

We measure the house, inspect the ductwork and electrical panel, check refrigerant lines and the condensate drain, and talk through what you want fixed — comfort, bills, noise, humidity.

2. Right-sized, written proposal

You get Manual J results in plain language, two or three matched equipment options at different efficiency tiers, and a written scope with no pressure and no same-day gimmicks.

3. Installation day

Permits pulled, old equipment hauled away, new pad and lineset set, matched system installed, refrigerant charged by measurement, full commissioning — then a thermostat walkthrough before we leave.

Local expertise

Why AC installation is different on the Grand Strand

Coastal South Carolina punishes lazy installs faster than almost anywhere else. The salt air that makes the beach the beach also eats condenser coils and rusts disconnect boxes — we spec coated coils and elevate equipment where storm surge and standing water are a risk. Summer design temperatures plus extreme attic heat mean the load calculation matters more here, not less: a system sized for an inland ranch will short-cycle in a Surfside Beach cottage with west-facing glass.

Housing stock varies street by street. Garden City and Surfside Beach have 1970s–90s beach boxes with original ductwork in hot attics; Carolina Forest and Socastee have newer builds with tighter envelopes but builder-grade equipment; Murrells Inlet and Pawleys Island have second homes that sit empty for months, where we plan for humidity control during vacancies. Hurricane season adds one more line item: whole-home surge protection for the new equipment, because one August storm can take out an unprotected board.

Common problems

Installation problems we see — and how we handle them

A bidder wants to install 'the same size you had'

Our fix Same-size swaps are how oversized, clammy systems happen. Our fix: a Manual J load calculation on every job, and we show you the numbers before you sign anything.

Salt air killed the last condenser in under a decade

Our fix Our fix: corrosion-resistant coil options, a proper pad and elevation, and a rinse schedule for oceanfront homes — plus honest talk about expected equipment life this close to the water.

Old lineset, rusted disconnect, tired pad

Our fix Our fix: we replace the lineset, disconnect, pad, and whip as part of the scope — not as surprise add-ons — and the permit covers the electrical work.

A low bid that skips the permit

Our fix Our fix: we pull the mechanical permit on every installation. It protects your manufacturer warranty and your home insurance, and the inspection catches mistakes before they cost you.

Pricing

What affects the cost of AC installation

We do not quote firm prices over the phone — any honest contractor needs to see the house first. These are the factors that move the number:

  1. System size and capacity: Tonnage follows the Manual J result, not the old nameplate. Bigger homes and poor insulation push capacity — and equipment cost — up.
  2. SEER2 efficiency tier: Higher-efficiency systems cost more upfront and less to run. We show you the tradeoff in plain terms for your usage.
  3. Ductwork condition: Undersized, leaky, or collapsing ducts can force duct repairs or replacement alongside the new system.
  4. Electrical and scope extras: Panel capacity, a new disconnect, lineset replacement, condensate pump, or surge protection each add scope.
  5. Equipment type: Straight-cool AC with electric heat versus a heat pump changes the equipment and the install labor — compare both where they fit.

FAQs

AC installation FAQs

How do I know whether to repair or replace my AC?

Age, repair history, and refrigerant type decide it. If your system is over 12–15 years old, needs a major repair like a compressor, or still runs on phased-out refrigerant, replacement usually wins. Our AC repair visit ends with an honest repair-vs-replace read either way.

What size air conditioner does my house need?

Whatever the Manual J load calculation says — not a square-foot rule. Two identical floor plans can need different sizes based on windows, insulation, and orientation.

Will a bigger AC cool my house better?

No. Oversized systems short-cycle: they cool fast, shut off, and leave humidity behind. Right-sized runs longer, dehumidifies properly, and lasts longer.

How long does an installation take?

Most straightforward replacements finish in one day. Jobs with ductwork changes, electrical upgrades, or difficult access can run longer — your written proposal states the timeline.

Do you handle permits and inspections?

Yes. We pull the mechanical permit, schedule the inspection, and register the equipment for warranty. Skipping permits voids warranties and creates insurance problems.

24/7 emergency line

AC died in the middle of a Grand Strand summer?

A dead compressor in July cannot wait for a quote process. We triage no-cool calls fast, stabilize you with repair options, and fast-track replacement when repair no longer makes sense. Call (123) 456-789 any time, day or night.
