Recycling Your Old Mercury-Containing Thermostats

In 2010, mercury thermostat collection legislation was passed in Illinois requiring thermostat manufacturers to establish collection programs for contractor and consumer-generated mercury thermostats. The legislation requires all HVAC wholesale distributors with facilities in Illinois to act as a collection point for waste mercury thermostats by July 1, 2011.

IT IS ILLEGAL TO DISPOSE MERCURY THERMOSTATS IN SOLID WASTE IN ILLINOIS. HVAC CONTRACTORS MUST RECYCLE ALL MERCURY THERMOSTATS THEY REMOVE FROM SERVICE. IT IS ILLEGAL TO LEAVE THEM AT THE CUSTOMER’S PREMISE. TRC IS THE EASIEST AND CHEAPEST WAY TO COMPLY WITH ILLINOIS LAW.

TRC provides collection containers to HVAC wholesale distributors, thermostat retailers, HVAC contractors, and Household Hazardous Waste programs for a nominal one-time charge.

Bring your mercury-containing thermostat to any TRC collection location for proper disposal. There are over 100 Collection Locations currently in Illinois. If your local HVAC wholesale distributor is not collecting waste mercury thermostats ask them to.
