Household Thermostats

 
Disposal

 

Some heating and air conditioning (HVAC) contractors, wholesalers and distributors collect wall-mounted mercury thermostats for recycling as part of a free national thermostat collection program.  Contact heating and air conditioning contractors and suppliers in your area to see if they participate in this program.

 

If a household hazardous waste collection event or facility is not available, small household thermostats may be disposed of in the regular trash. This is the least-preferred disposal option, but it may be the only option available in some areas.

 

Thermostats should be placed in a strong plastic zip top bag and wrapped in several layers of newspaper.  The wrapped newspaper should be sealed with strong tape and placed in the trash.  

 

Spill Cleanup Guidance

 

These procedures are intended for small devices like thermometers or thermostats from households only.  Contact your local health department or a hazardous waste disposal company for assistance in disposing of larger quantities of liquid mercury.
