How to safely dispose of thermostats

A-Z Listing

 Thermostats

Manual dial thermostats

Older thermostats with manual dials may contain mercury. Safely dispose of these thermostats for free at a household hazardous waste drop-off location:

Special instructions

  • Package thermostat in a puncture-resistant, non-breakable, sealed container like a yogurt or margine tub.
  • Label the container as "thermostat" or "mercury" with a permanent marker.
  • Call 911 if a thermometer, thermostat, or wall-mounted blood pressure cuff is broken and mercury is released.

Programmable thermostats

Modern digital thermostats (programmable with a display) do not contain mercury. They can be placed in your black cart as garbage.
