HVAC equipment in Henderson must comply with HMC Title 8 noise limits of 55 dBA daytime and 50 dBA nighttime at the property line, with setback and screening requirements for condensers in residential zones.
Henderson regulates HVAC noise through both HMC Title 8 general noise ordinance provisions and Title 19 zoning development standards. For single-family residential zones, exterior air conditioning condenser and heat pump units must not exceed 55 dBA at the property line during daytime hours (7 AM to 10 PM) and 50 dBA during nighttime hours. Units must be set back at least 3 feet from any property line and cannot be located in required front yard setbacks. Walls, fences, or screening may be required to reduce transmission when the unit is near a neighbors bedroom window. Commercial rooftop HVAC units are regulated through Title 19 Major Projects Standards requiring parapet screening so equipment is not visible from public rights-of-way. Evaporative coolers (common in some Henderson homes due to dry climate) must also meet noise limits and comply with cross-connection backflow prevention. Frequent complaints about older condensers are investigated by Code Enforcement, which can require repair or replacement.
