Attention to all Los Angeles county air conditioning companies.

Out-of-service mercury-added thermostats are classified as universal waste in California. Universal wastes are certain commonly-generated hazardous wastes that are managed under special rules that are easy to understand and follow. Any person who is required under this law to handle or transport mercury added thermostat is regulated under California’s Universal Waste Regulations (Cal. Code Regs., tit. 22, ch.23*) as a universal waste handler. A contractor who installs heating, ventilation, and air conditioning components or a building demolition professional that removes out-of-service mercury-added thermostats from a building is required to handle and transport mercury thermostats in accordance with these regulations.
