How much does commercial HVAC service cost in Houston?

Commercial HVAC costs vary significantly based on system size, building type, and scope of work. Routine maintenance visits typically cost $200-$500. Emergency repairs range from $300-$3,000 depending on the issue. Complete commercial HVAC replacement costs $15,000-$100,000+ based on building size and system complexity. AOT Mechanical provides transparent pricing with detailed written estimates for all commercial projects.

How often should commercial HVAC systems be maintained in Houston?

Houston commercial HVAC systems should receive professional maintenance quarterly (every 3 months) due to heavy usage and demanding climate conditions. High-usage facilities like restaurants or data centers may require monthly service. Minimum maintenance should be twice annually—before cooling season and before heating season. Regular maintenance prevents costly breakdowns, maintains efficiency, extends equipment life, and ensures your Houston business meets building code requirements.

How long do commercial HVAC systems last in Houston's climate?

Commercial HVAC systems in Houston typically last 12-20 years depending on system type, usage, and maintenance. Rooftop units average 15-20 years, while larger chillers may last 20-30 years with proper care. Houston's demanding climate—extreme heat, high humidity, and extended cooling season—places additional stress on commercial HVAC equipment compared to cooler climates. Regular professional maintenance significantly extends system lifespan and delays costly replacement.
