Corpus Christi does not have HVAC-specific noise provisions. HVAC equipment must comply with the general Chapter 31 limits of 70 dBA daytime and 60 dBA nighttime measured at the receiving property.
Corpus Christi does not single out HVAC equipment in its noise ordinance. Residential and commercial HVAC systems including air conditioners, heat pumps, and rooftop units must comply with the general Chapter 31 decibel limits: 70 dBA during daytime hours and 60 dBA during nighttime hours measured at the receiving property. Given the citys hot subtropical climate, air conditioning runs extensively from April through October. Most modern residential AC units produce 50-65 dBA at the unit, which typically falls below the 60 dBA nighttime limit at neighboring property lines with standard setbacks. Improperly maintained or failing units may exceed limits. Commercial rooftop HVAC units in mixed-use areas should be evaluated for compliance at the nearest residential property line. Building code requirements for mechanical equipment placement and screening provide additional buffer. Complaints about HVAC noise can be directed to Code Compliance through 311.
Fine up to $500 if noise exceeds applicable Chapter 31 thresholds. Property owners are responsible for maintaining equipment to avoid nuisance noise levels.
