With summer quickly approaching, homeowners are making sure their AC systems are in working order. This is not only a matter of comfort and convenience, but one of safety as well. If you are having problems with your system, do not wait until the extreme heat is upon to get it checked out.

Many factors can contribute to AC system breakdown. A common culprit is a faulty AC sensor.

This article lays out some of the symptoms and causes of AC sensor failure. It also gives you some basic information on prospective fixes. Keep reading to find out more.

How AC Sensors Work

Almost every AC system has an ambient temperature sensor. This is a component located on the thermostat, usually near the evaporator coils. Some smart home systems have sensors that you can place in different rooms throughout your home.

An air conditioner sensor compares the ambient temperature with the temperature set on the thermostat. It then tells the system to make adjustments, activating the compressor when it is too warm and turning it off when it reaches the desired temperature. Without it, your system has no way of determining indoor temperature, which means it cannot make your AC cycle on and off.

Common Signs of AC Sensor Problems

Almost any failure of your HVAC system to kick on could be the result of a faulty AC sensor. There are other common clues that yours has gone out, though, beyond failure to start up.

One main sign is the failure of your AC to turn off when the space has reached its desired temperature. Even if it does finally shut off, this could be a sign that your sensor is damaged and not reading the ambient temperature.

If you notice your system running longer than usual or rooms becoming very cold, this could be a sign that your sensor reading is off. You may find yourself manually turning the AC off to keep it from blowing all the time.

Solutions to AC Sensor Issues

AC malfunctions could be the result of the buildup of dirt in the unit that is disrupting signals. A thorough cleaning inside the component may fix this issue. This DIY fix is worth a try if you can identify the location of the sensor.

Having your HVAC system components cleaned also ensures that it is running as efficiently as possible. This can save you money on your utility bill as well as reduce wear and tear on your system.

Improper installation of a new thermostat is another common cause. This issue has increased with the advent of smart thermostats that require a half dozen or more wires to operate your HVAC system. This too is a simple repair that warrants rewiring or––worst case––the installation of new wires between the thermostat and the system.

Another reason that an AC sensor is not functioning well is that it has become dislodged. This can inhibit its access to the surrounding air to read the temperature.

In some cases, sensors can be repaired. Although, replacing the broken thermostat may be the easiest course of action (depending on its age and functionality otherwise).
