Compare up to three local Myrtle Beach HVAC contractors from Henry's vetted bench — AC repair, furnace and heat pump service, and full system replacement.

When to schedule HVAC work in Myrtle Beach
Myrtle Beach summers run hot and humid from May through September, with heat pumps and AC systems often running near-continuously to keep condos and coastal homes dry inside as well as cool. Hurricane season (June through November) adds risk of storm damage, power surges, and flooding to outdoor units, which is why many local homeowners schedule a spring tune-up before peak season and again after any major storm. Winters are mild, but heat pumps still handle heating duty on the coldest nights, so a system that's neglected in summer often fails when homeowners first switch it to heat mode in the fall.
Permits and HOA rules
Inside city limits, HVAC replacement and most repair work involving refrigerant lines or electrical circuits requires a mechanical permit through the City of Myrtle Beach Construction Services Department, and permits can only be issued to a state-licensed mechanical contractor or certified master tradesman with a current City business license and trade card 2. For properties outside city limits in unincorporated Horry County, permitting runs through Horry County's Building Codes/Permitting office instead. A reputable contractor will pull the permit and schedule the required rough and final inspections as part of the job rather than skipping the step, which matters for insurance claims and resale on rental and second-home properties.
Licensing and insurance in South Carolina
South Carolina HVAC contractors must hold a Mechanical Contractor license issued by the South Carolina Department of Labor, Licensing and Regulation (LLR) through its Contractor's Licensing Board, which requires a qualifying party to pass technical and business/law exams and carry the required bond before doing licensed mechanical work 1. You can verify any contractor's license status directly on the SC LLR website before signing a contract, and in Myrtle Beach that state license has to be paired with a City of Myrtle Beach business license and trade card for work performed inside city limits 3.
Why coastal salt air changes your HVAC math
Homes within a few miles of the Grand Strand deal with airborne salt that accelerates corrosion on outdoor condenser coils and cabinets far faster than in inland South Carolina. It's common to see aluminum fins and copper connections pitting or thinning years before a manufacturer's rated lifespan, especially on units installed close to the beach or on lower floors near the Intracoastal Waterway.
Because of this, many local contractors recommend coastal-rated equipment with factory-applied coil coatings, or an added protective coating at install, along with more frequent rinsing of the outdoor unit to remove salt buildup. Homeowners who skip this often find themselves replacing a condenser at year 7 or 8 instead of year 12 to 15.
Heat pumps are the default system on the Grand Strand
Most homes and condos in the Myrtle Beach area run heat pumps rather than separate furnace-and-AC setups, since winters are mild enough that a heat pump can handle both heating and cooling efficiently. This affects repair costs (reversing valves and defrost boards are heat-pump-specific parts) and replacement costs, since sizing a heat pump correctly for a coastal home's humidity load is different from sizing a straight AC system.
If you're getting quotes, make sure contractors are pricing an actual heat pump replacement rather than a conventional AC-only system, since the two aren't interchangeable and mixing them up is a common source of quote confusion.
Rental condos and second homes add wrinkles
A large share of Myrtle Beach's housing stock is short-term rental condos or seasonal second homes, which changes how HVAC problems get handled. Systems left unattended for weeks between owner visits can develop mold in ductwork from humidity, or freeze up unnoticed if a filter clogs, and rental turnover schedules mean repairs often need to happen fast between guest bookings.
If you manage a rental property, ask contractors whether they offer remote monitoring add-ons or priority scheduling for vacancy windows, and make sure whoever holds a key or lockbox code is a company you've vetted, since access issues are one of the most common friction points for absentee owners.
Humidity control matters as much as temperature
Coastal humidity in Myrtle Beach regularly sits well above what inland South Carolina sees, and an oversized AC or heat pump that cools a room quickly without running long enough to pull out moisture can leave a home feeling clammy even at a comfortable temperature. This is a common complaint after DIY-sized replacements or after a system is swapped without a proper load calculation.
A correctly sized system, sometimes paired with a whole-home dehumidifier, does a better job managing indoor air quality and reduces the musty smell and mold risk that humid coastal homes are prone to.
Hurricane season prep and post-storm inspections
Outdoor condensers and heat pump units are exposed to wind-driven debris, flooding, and power surges during tropical storms and hurricanes. Homeowners near flood-prone areas should ask about elevating outdoor units on stands, and everyone in the area benefits from surge protection on HVAC equipment given how often the coast sees storm-related power fluctuations.
After any named storm, it's worth having a contractor check refrigerant lines, electrical connections, and the condenser cabinet for storm damage before running the system hard again, since a unit that looks fine but took in debris or moisture can fail within days.

Common questions
Why do AC units near the Myrtle Beach coast fail sooner than in other parts of South Carolina?
Salt air accelerates corrosion on condenser coils, fins, and cabinets, which is why units close to the ocean often need replacement years earlier than the same equipment inland. Coastal-rated equipment and regular rinsing help extend that lifespan.
Do I need a permit to replace my AC or heat pump in Myrtle Beach?
Yes. Inside city limits, mechanical permits are required for most HVAC replacement and significant repair work, and only a state-licensed mechanical contractor or certified master tradesman with a City business license and trade card can pull one. Properties in unincorporated Horry County permit through the county instead.
How do I check if an HVAC contractor is licensed in South Carolina?
Search the contractor's name or license number on the South Carolina LLR Contractor's Licensing Board website to confirm they hold a current Mechanical Contractor license.
Is a heat pump better than a standard AC system for Myrtle Beach homes?
Most homes here use heat pumps because winters are mild enough that one system can handle both heating and cooling efficiently, which is why heat pumps are the dominant system type along the Grand Strand.
How often should HVAC systems be serviced in a coastal climate?
Most local contractors recommend twice-yearly maintenance, once before summer and once before winter, plus an inspection after any major hurricane or tropical storm.
What should rental property owners do differently for HVAC care?
Set up regular filter checks and consider remote monitoring, since vacant units between guest stays can develop humidity or freeze-up problems that go unnoticed for days or weeks.
