Optimizing Humidity with Nest Thermostat: A Comprehensive Guide

Nest thermostat regulating humidity


So, you’ve recently upgraded your thermostat to a Nest, and now you’re curious – can the nest thermostat regulate humidity levels in your home? We’re here to delve into this inquiry and provide you with a comprehensive answer.

In a nutshell, the answer is a resounding “yes.” The Nest thermostat has the capability to indirectly control humidity. By utilizing the “Cool and Dry” setting, designed for systems with a built-in dehumidifier mode, the Nest can detect high humidity levels and initiate on-demand air conditioning. For systems lacking a built-in dehumidifier mode, the Cool and Dry setting still proves effective in managing humidity.

Understanding the Nest Thermostat

Created by Tony Fadell, the Nest thermostat stands out as a smart, programmable device with self-learning features and Wi-Fi connectivity. Its innovative design allows users to remotely control and customize their home climate.

Mechanisms for Humidity Control

1. Systems with Dehumidifier Mode:

Many modern air conditioners come equipped with a dehumidifying function designed to cool and dry the air simultaneously. The Nest thermostat, when set to “Cool and Dry,” taps into this built-in dehumidification mode, actively reducing humidity levels. This feature not only contributes to a more comfortable atmosphere but also aids in preventing mold growth, fostering a healthier living environment.

2. Cool and Dry Feature:

When the Nest thermostat is linked to a system lacking a dehumidification mode, it doesn’t lose its efficacy. The Cool and Dry feature operates by leveraging the natural cooling capabilities of the air conditioner. By converting hot and humid air into cooler, drier air, it effectively controls humidity levels. The thermostat’s high humidity detection prompts the activation of the air conditioner, efficiently toggling it on and off to maintain optimal humidity.

It’s important to note that enabling Cool and Dry on a system with dehumidifier mode might lead to increased power consumption, as the air conditioner or central HVAC system could run more frequently. Therefore, it’s advisable to utilize this feature judiciously, particularly in extremely humid climates.

Is the Nest Thermostat Worth the Investment?

While Nest thermostats may carry a higher price tag than traditional counterparts, their advanced features and potential for energy savings make them a worthwhile investment. Compatible with Wi-Fi and smartphone apps like Nest or Google Home, these thermostats offer remote control capabilities. Additionally, they can be voice-controlled, making them convenient and user-friendly.

Advantages of Nest Thermostat:

1. Energy Efficiency:

Nest Thermostats boast impressive energy-saving capabilities, with reported savings of 10-12% on heating and 15% on cooling for US customers. This translates to annual savings ranging from $131 to $145. The device learns from user behavior over time, automatically determining energy-efficient settings.

2. Integration with Google Nest Ecosystem:

Nest thermostats seamlessly integrate with other Google Nest products, creating a connected home environment. This includes compatibility with smoke detectors, doorbells, security cameras, and speakers.

3. Automatic Issue Detection:

The thermostat keeps a vigilant eye on the heating, air conditioning, or central HVAC system, alerting users to potential issues. For instance, it may notify if the air conditioner takes longer than usual to cool the house.

Disadvantages of Nest Thermostat:

1. Higher Cost:

Compared to traditional thermostats, Nest thermostats come with a higher upfront cost. If a multi-story home requires a thermostat on each floor, the expense may increase accordingly.

2. Installation Complexity:

Installing a Nest thermostat is more complex than a non-smart thermostat, potentially requiring professional assistance, especially for proper connection to the air conditioning system or humidifier.


In conclusion, a Nest thermostat proves to be a smart investment for those seeking energy efficiency, convenience, and advanced climate control features. Whether optimizing humidity or seamlessly integrating with a smart home ecosystem, the Nest thermostat adds value to both comfort and sustainability. Make the smart choice and consider integrating a Nest thermostat into your home today.
