Top 5 Freeze Alarms for the Home

If you want to receive a warning when the temperature in your home drops dangerously low due to a furnace failure or power outage, you need a freeze alarm.  A freeze alarm is a device that monitors the temperature inside your home and sends you an alert so you can intervene, before you wind up with frozen pipes that burst.  There are many types of freeze alarms to choose from and costs range from under $50 to around $350.  To protect your home against freezing pipes, select a freeze alarm based on:  (1) How it communicates — landline phone, WiFi or cellular; (2) How you want to be alerted — phone call, text message or email; and (3)  Any other conditions you want to monitor, in addition to temperature.  Here are our 5 best selling freeze alarms, beginning with the least expensive.  freeze alarms
