AC Replacement in Myrtle Beach, SC: What to Expect

Myrtle Beach sits along the Grand Strand, where summer temperatures push into the high 80s with roughly 45 days exceeding 90 F and humidity hovering around 75% off the Atlantic. This combination forces cooling systems to handle enormous latent moisture loads from May through October, creating relentless strain on aging equipment. Ocean-moderated winters with lows around 36 F keep heating demand modest, meaning the primary investment here centers on reliable cooling. Twenty-two contractors serve this market, collectively holding roughly 9,100 reviews that average a 3.5-star rating, making AC Replacement in Myrtle Beach a decision worth researching carefully.

For replacement units, pricing depends heavily on cooling capacity and efficiency ratings. A basic 3-ton central system runs $5,500 to $11,000, while a mid-efficiency 4-ton unit spans $7,500 to $14,000. High-efficiency 5-ton systems reach $9,500 to $16,000, with the wide ranges reflecting differences in equipment quality, installation complexity, and whether existing infrastructure needs modification. South Carolina law requires all HVAC contractors to hold a Mechanical Contractor Group 2 HVAC license from the state's Licensing Board, ensuring baseline professional competency.

Customer feedback reveals clear patterns among higher-rated contractors. Reviewers repeatedly mention same-day or same-week service responsiveness, with technicians arriving quickly during heat-related emergencies. Several reviews specifically praise contractors who arrive within 30 minutes of the call and demonstrate willingness to repair units that other companies decline. Across the top-rated portfolios, prompt response times and availability during urgent situations appear as consistent themes.
