Annual maintenance for a single rooftop unit typically ranges from $500-$2000, while comprehensive service contracts for small businesses under 5,000 square feet run $1000-$5000 annually. Mid-size commercial properties between 5,000 and 25,000 square feet generally fall within a $3500-$10000 annual contract range, with pricing influenced by system complexity, equipment age, service response times, and whether the contractor offers 24/7 emergency availability. These costs reflect the specialized expertise required, as South Carolina mandates that commercial HVAC contractors hold a Mechanical Contractor Group 2 HVAC license from the state's Licensing Board to perform installation and major repairs.
