Cochrane's Fire Inspector is reminding homeowners to change the batteries in their smoke detectors while they turn their clocks back for Daylight Saving Time this weekend. 

Fire Inspector Jeff Avery says it's a good time to change your batteries in your CO detector as well. 

He says it's important to change the batteries on the detectors that are also hardwired in because the batteries can still drain. 

Avery says you should also change the batteries on your thermostat as they did have a call last year where the battery died and the furnace didn't run and pipes ended up freezing as a result. 

The clocks change over at 2:00 AM Sunday.
