Where Should I Put My Thermostat Temperature Sensors?

August 5th, 2021 by Emily Mixter

The thermostat is the most vital part of your HVAC system. However, one of the biggest problems towards keeping a steady, comfortable temperature is ensuring that it has the data it needs to do its job, and that means the proper placement of each temperature sensor. Fortunately, finding the proper placement of each temperature sensor is a piece of cake.

The Best Places to Put Your Sensors

An HVAC professional can help you find the best placement for each temperature sensor, but lacking that access you can determine them yourself. You are looking for spots away from ducts and equipment that cools or heats on a regular basis; these can create the impression that the area surrounding them is hotter or colder, causing the thermostat to heat or cool based on the equipment and not the actual environment. This makes near a refrigerator or other large appliance bad placement for a temperature sensor.

You should also consider placement relatively low, usually under five feet. A temperature sensor placed too high will read the heat rising from the floor or possibly catch the flow of an HVAC duct, causing another sort of false impression. On the ceiling itself is a bad idea, especially if you place it near the fan. Conversely, putting the temperature sensor too low can make it read too cold as the heat escapes to the ceiling.

You should also avoid placing the sensor in areas that warm up quickly, such as where sunlight falls. Areas near doors and windows should also be avoided; they represent both areas where you want the air to escape, as well as areas that see a lot of heat and cold fluctuations. Your sensors should be placed in areas where the temperature is somewhat constant for best results.

Checking The System

Modern technology has helped to take out some of the guesswork of temperature sensor placement. Sensors can be linked to an app that constantly checks them, showing you what the sensors are seeing, and allowing you to get a better feel for which areas are throwing off the HVAC system. You can then properly place the sensors so that the thermostat can do its job better. While there will be some moving the sensors around in order to find the best places, it can be worth the time when it comes to your comfort.
