In this video, Steve Nagy and Chris Cherry, alongside guest member Madeline D, demonstrate how cold or hot wall temperatures can affect thermostat readings. While digital and smart thermostats are generally considered more precise than older analog models, they can still deviate by as much as 4°F, as shown in this video.
Not all but many homes experience wall cavity temperature variations due to several factors, such as inadequate insulation, new electrical wiring, new plumbing, (where crew members drill through wood or concrete and don't seal the openings properly) wind washing effects, or simply being older structures. Cold or hot attic air can enter the interior wall cavity. HVAC companies in the U.S. often address these issues and seal the wall behind the thermostat.
The team used exaggeration to illustrate how the temperature of a wall can affect thermostat accuracy. As Chris pointed out, if the wall temperature skews the thermostat by just one degree, it could lead to a 3-4% increase in energy bills. Since people perceive temperature differently, they may not accurately gauge the exact temperature, which is why thermometers are essential. Enhancing temperature accuracy your thermostat, ultimately leads to savings on energy bill, less repairs and better longevity of HVAC systems.

We tested several thermostats for this demonstration, including the Honeywell thermostat, Pro 1 thermostat, Emerson thermostat, Ecobee smart thermostat, Sensi smart thermostat, Google Nest smart thermostat, Google Nest Learning smart thermostat, and Lennox Smart Communicating thermostat. Some thermostats performed better than others at room temperature, while others excelled in the presence of cold or hot wall temperatures.

Whether operating in cooling or heating mode, inaccurate wall temperature readings can lead to increased energy consumption by the HVAC system. Fluctuations in wall cavity temperature can arise from various factors, and HVAC companies frequently address this issue.

To assist homeowners, we developed a customized gasket-making method using cling wrap. For those who are more handy, we recommend the foam injection method; however, it’s crucial to strictly follow the instructions and avoid injecting more than 1/3 of a can of expanding foam, especially in 2x4 walls.

Please note that manufactures of Emerson, Pro, Honeywell, Ecobee, Sensi, Nest, and Lennox did not provide us with any products or compensation for this review.
