Resources for thermostat recycling
Some wall mounted thermostats use mercury switches to sense and control room temperature in heating, ventilation and air conditioning (HVAC) equipment. Mercury thermostats were widely used in California prior to 1992 and were legal to buy until 2006. The mercury switch is a glass vial with mercury in it which conducts electricity to the temperature control equipment. Replace mercury thermostats with non-toxic programmable (digital) thermostats.
Why should mercury thermostats be recycled?
Approximately 3 grams of mercury is used in a thermostat. Disposing of old thermostats, using traditional methods (throwing out in the trash) result in breakage, allowing mercury to be released into the environment. Elemental mercury is a powerful neurotoxin and does not break down, but builds up in fish, birds and people. Inhaling or ingesting mercury over time can cause irreversible damage to the brain, kidneys, or to developing fetuses. The safe recovery of mercury-containing thermostats prevents pollution and protects public health.
About the Mercury Thermostat Collection Act of 2008
AB 2347 requires that beginning July 1, 2009 all heating and air conditioning wholesalers with physical locations in California will be required by law to collect end-of use thermostats from the public at no charge.
