Read on to see which freeze alarm is best suited for your application.

A freeze alarm can give you peace of mind whether your plumbing is prone to freezing pipes or you have a more expensive, complex plumbing or HVAC system. In our testing, we purchased and tested top models, including wireless alarms, water alarms, and sensor alarms, to assess ease of use and reliability. A water alarm, for example, can detect leaks in your home's plumbing and alert you before costly damage occurs. Unfortunately, not all alarms are created equal, and our experts were able to point out models lacking key features or failing on vital functions. Read on to see which alarm is best for your needs.

The Leak Detect 360 WiFi Water Leak and Freeze Detector does everything its name implies: It detects water leaks and frozen pipes, and it sends alerts to your smartphone when a leak is detected. The 360 has a sleek, modern design, plus a built-in sensor that detects water, leaks, or freezing temperatures.

Control Products FreezeAlarm Dialer Temperature Alarm FA-700 with 1 phone voice message notification / monitor for low or high temperature extremes / No monitoring fees

Control Products FreezeAlarm Dialer Temperature Alarm FA-700 1 with phone voice message notification

by Control Products

Uses existing telephone line, DSL or VOIP phone connections*

The FreezeAlarm FA700 alarm dialer is easy to use and is loud enough to sound in rooms where it's positioned. It has one of the easiest dials we've seen, and the alarm dialer can dial up to two telephone numbers. It does have a couple quirks. First, the alarm dialer doesn't automatically dial when the batteries are low, so you'll need to manually press the dial button. Second, an alarm is sounded every 15 minutes, so the alarm doesn't go off as often as we'd like. However, this alarm dialer's biggest drawback is that it isn't very reliable. We experienced frequent failures, often shortly before it was scheduled to call. The alarm dialer also is difficult to program; you can't customize a dial-out schedule, and an alarm must be manually activated. If the batteries die, you'll need to replace the alarm dialer's backup batteries, and the alarm dialer doesn't tell you this until the alarm is triggered. On top of all that, the alarm dialer's website is only in German, but you can download an English manual.

Easy setup in minuteswithout tools or professional installation. Requires Ring Alarm Security System (sold separately).

The Ring Alarm Flood and Freeze Sensor is easy to install, (it takes about 10 minutes) and it took five minutes to set up our test unit and connect it to our test Ring Alarm system. It detected water and low temperatures immediately when we turned our test unit on. The sensor's mobile app and online dashboard let us configure our Flood and Freeze Sensor, set custom alert levels for water and low temperatures, and view alerts. It also let us customize our Flood and Freeze Sensor's sensitivity, and, when we made changes, the sensor immediately updated its setting. The sensor's battery lasts for about three years, which is about as long as many smart security cameras have, and when we changed it, it sent us a message to let us know it was ready. The Ring Alarm Flood and Freeze Sensor is easy to set up and use, and it will keep your home safe (and save you money) from water damage and freezing.

The Freeze Alarm Homesitter Temperature, Water, Power Alarm is the most dependable water, power and temperature sensors we've ever tested. The alert system sounds three different tones when it detects a problem. Each alarm notifies up to three phone numbers, so you can alert the usual suspects (your kids, your spouse, your neighbor), as well as a 24-hour phone number for emergencies. Alerts can also be sent to your smartphone, and you receive a text for each alert. The alarm can also be set to sound off automatically whenever any of these problems occur. The freeze alarm has the longest detection range of any water, power and temperature sensor we tested: 12 feet. The temperature sensor is accurate to 3 degrees Fahrenheit, and the water sensor is accurate to 1.5 degrees. The sensor ranges are extended if you use the Freeze Alarm with an external temperature sensor. The alarm also monitors humidity levels and alerts you when humidity levels reach 40%. The Freeze Alarm's power-out alarm has the longest detection range of any of the power-out alarms we tested: 8 feet. The FreezeAlarm Homesitter Temperature, Water, Power Alarm is easy to set up. Just plug the FreezeAlarm into an AC outlet, and plug the included sensor probes into a water source and electricity source, respectively. The FreezeAlarm uses batteries, which need to be replaced after 3 to 5 years.
