Climate & why HVAC matters.

North Charleston enjoys 230 days of sunshine and a 294‑day growing season. Average temperatures hover around 65.7 °F, with highs near 75.2 °F. Morning humidity averages 86 %, dropping to 56 % by afternoon. Humidity peaks at 79 % in August and averages 72 % annually, making summers feel hotter. Winters are mild; January highs are about 15 °C (59 °F). These conditions strain AC units and promote mold growth, so dehumidification and regular maintenance are essential.

How 5 Star helps:

• Installations & replacements: We design systems—central air, heat pumps, ductless mini‑splits—suited to single‑family homes, historic cottages and large commercial buildings.
• Repairs & maintenance: High humidity corrodes components; our technicians fix refrigerant leaks and failed compressors and offer 24/7 emergency service. Routine tune‑ups keep equipment efficient.
• Indoor air quality: Whole‑home dehumidifiers and high‑MERV filters control moisture and allergens.
• Commercial HVAC: From Boeing to the Coliseum campus, we install rooftop units, VRF systems and automation for offices, venues and factories.
• Energy efficiency: We recommend high‑SEER equipment, smart thermostats and insulation to reduce utility costs.

Neighborhoods & attractions we serve.

• Park Circle: A garden community planned in the early 1900s, its street grid revolves around a central circular park. East Montague Avenue offers sidewalk dining and unique shops. The area hosts a free disc golf course with 18 tee boxes and 18 baskets and maintains a small‑town feel.
• Riverfront Park: Along the Cooper River, this park features a large meadow, performance pavilion and waterfront views. Visitors enjoy swinging benches, paved walkways, picnic tables and oak trees.
• North Charleston Coliseum & Performing Arts Center: The coliseum is a 13 000‑seat multi‑purpose facility opened in 1993; it’s home to the South Carolina Stingrays hockey team and hosts major concerts. The adjacent 2 300‑seat Performing Arts Center stages concerts, ballets and symphonies.
• Other areas: We also serve Oak Terrace, Dorchester Terrace, Wando Woods and commercial districts near the airport and Tanger Outlets.

Common HVAC challenges & solutions.

Humidity causes condensation and mold; we install systems with dehumidification and recommend regular maintenance. Salt‑air corrosion near rivers and marshes is mitigated with corrosion‑resistant equipment. Storms and heavy rainfall (about 50 inches a year) require elevated outdoor units and surge protection. Large venues need high‑capacity systems with precise climate control.
