What areas of Horry County do you serve?

Short Answer: We serve the whole county, including Myrtle Beach, North Myrtle Beach, Conway, Carolina Forest, Socastee, Surfside Beach, Little River, and Longs. Pick your town for local detail on AC repair, costs, and the conditions specific to where you live.

Horry County runs from the Atlantic oceanfront down to the inland river town of Conway, and a home in one is not much like a home in the other. Start with your town: AC repair in Myrtle Beach, AC repair in North Myrtle Beach, or AC repair in Conway. We also cover Carolina Forest, Surfside Beach, Socastee, and Little River.

Who issues AC permits in Horry County?

Short Answer: It depends on where you live. In unincorporated Horry County, the County Code Enforcement Division issues mechanical permits and inspects to the International Mechanical Code. Inside Myrtle Beach, North Myrtle Beach, and Conway, each city runs its own building department with its own flood rules.

A licensed mechanical contractor pulls the permit for an AC replacement, new ductwork, or a mini-split, and the work is inspected to the International Mechanical Code (the rule). In unincorporated areas that is Horry County Code Enforcement (the authority); inside the cities it is the city building department, and the flood-zone freeboard rules differ by jurisdiction, for example the added freeboard required in North Myrtle Beach versus Conway, and we confirm the current figure for your address. We handle the permit and inspection wherever you are. A new system meets the 14.3 SEER2 minimum for our region, and refrigerant work is done by technicians certified under EPA Section 608.

How much does AC repair cost in Horry County?

Short Answer: Most AC repairs across Horry County run about $150 to $600 after a service call to diagnose the problem. Bigger jobs like a refrigerant leak repair, compressor, or coil cost more. We give you the estimate before we start, so there are no surprises.

Typical area ranges to help you plan, not a quote. Your exact price depends on the part and your system, and we confirm it after we diagnose the unit.

If a repair climbs toward the cost of a new system, we will say so honestly, and financing is available through our financing options. A high-efficiency heat pump may also qualify for a Santee Cooper rebate when a Trade Ally installs it, which we are.

How do AC conditions change across Horry County?

• Short Answer: They change a lot. On the beach, salt air is the big enemy and can cut an AC's life from 10 to 15 years into the 5 to 10 year range on the oceanfront. Inland in Conway, salt is barely a factor; the issues are older systems and Waccamaw River flooding. Knowing the difference is half of doing the job right.

Out at Myrtle Beach, North Myrtle Beach, Surfside, and Little River, salt air corrodes coils and wears out capacitors and contactors faster, so coastal units need more frequent rinses and checks. Inland at Conway, you trade salt for older Historic District homes, more R-22 systems near the end of their road, and river-flood rules instead of coastal ones. The growth corridors like Carolina Forest and Socastee sit in between, mostly newer heat pumps. We size our advice to where you actually live, because a beach condo and a riverfront colonial do not need the same thing. That local read is not better, just different from a one-size-fits-all chain.

Do you offer emergency AC repair across Horry County?

Short Answer: Yes. We prioritize emergencies and work nights and weekends across the whole county, from the beach to Conway. In peak summer it can take a little longer with demand all over the Grand Strand, and we will give you an honest time window when you call.

A hot house in a Horry County July is no small thing, especially for kids, older family, or a rental with a tenant in it. We move emergencies to the front of the line wherever you are in the county and tell you straight where you stand. Treating folks right for the long term is how we have lasted on this coast since 1947. A simple call starts it. Request service or call (843) 238-3838.

Do you have more than one office in the county?

• Yes. We run local offices in Myrtle Beach and Charleston and dispatch across all of Horry County, from the beach towns to inland Conway. That local footprint is part of how we have served the Grand Strand since 1947.

Do you repair heat pumps and ductless mini-splits across the county?

• Yes. Our certified and licensed technicians service central air conditioners, heat pumps, and ductless mini-splits countywide. Whatever type of cooling your home runs, we can diagnose and repair it, from the beach to inland Conway.

What AC brands do you install and service?

• We service and install all major brands of central air and heat pumps, plus Mitsubishi for ductless systems. We service the system you already have rather than push you toward a brand you do not need.

Do you offer a maintenance plan for homes across the county?

• Yes. Our VIP Maintenance Club schedules regular tune-ups countywide, from beach homes where salt speeds up wear on the outdoor unit to inland systems that just need steady care. Regular visits catch a weak capacitor, dirty coil, or low refrigerant before they leave you without cooling.

How do I find the page for my specific town?
