8 Best Attic Fan Thermostats: Reviews & Buying Guide

Improving attic ventilation can make your home more comfortable, and using an attic fan thermostat is key. Without control, attic temperatures can get really hot, which can damage your roof and make your home less comfy and more energy-hungry.
Attic fans help, but you need to manage them right. If you’re planning to get one today, here’s what to think about:

  • Temperature Range: Most thermostats have settings from 80°F to 120°F, but think about your climate. If it’s really hot where you live, go for one with a lower setting, around 90°F. For more control in milder climates, choose a wider range, like 80°F to 130°F.
  • Fan Capacity: Regular attic fans use less than 10 amps of electricity. If you have a stronger fan that uses more than 10 amps, get a thermostat that can handle around 15 amps to avoid damage.
  • Humidity Control: Not all thermostats have this feature. This lets the thermostat turn on the fan based on humidity levels in the attic. Find a model that allows you to activate the fan anywhere from 30% to 90% humidity. 

Although these aspects are significant, choosing an attic fan thermostat involves considering a broad range of factors. Therefore, the top attic fan thermostats featured in this list come with comprehensive explanations of their key features and specifications, accompanied by a detailed “Buying Guide” to assist you in selecting the ideal attic fan thermostat.

Buying Guide for the Best Attic Fan Thermostats

If you’ve got an attic, keeping it cool is crucial for maintaining a comfortable temperature throughout your home, especially in the summer. Running your attic fan constantly isn’t the most efficient solution. That’s where the best attic fan thermostats come in handy. These devices automatically adjust your attic fan based on the current temperature, ensuring optimal cooling while saving energy. In this section, we’ll explore the top features and factors to consider when choosing the best attic fan thermostat.

1. Temperature Range

When considering a thermostat for your home, like an attic fan thermostat, it’s important to assess its temperature range. This range dictates the temperatures at which your attic fan will activate or deactivate.

Typically, attic fan thermostats cater to the needs of most users with a temperature range spanning from 60 to 120 degrees Fahrenheit. However, for those seeking a bit more flexibility, there are options available with a range of 50 to 120 degrees Fahrenheit in certain cases.

2. Maximum Current

Irrespective of the temperature range your attic fan thermostat offers, making sure that it supports a high maximum current rating is quite important. This is to ensure that your attic fan thermostat can handle the load of your attic ventilation fan even if it is a high-performance one. 

Usually, most attic fan thermostats will offer a maximum current value of up to 10 amps with some models offering slightly lower or higher values. But for most users and the attic fans that they are using, a maximum current value of up to 10 amps will be enough.

3. Humidistat

Some of you would also want your attic fan to turn on or turn off depending on the current humidity in your attic. In that case, you can go with an attic fan thermostat which also comes with an inbuilt humidistat. This allows you to set a specific humidity value at which your attic ventilation fan gets toggled. 

Similar to the temperature setting, the humidistat of your attic fan thermostat also comes with a humidity range like 30% to 90% where you can choose any value of your choice.

4. Warranty

Just like the attic ventilation fan that you are using, you would also want your attic fan thermostat to stay functional for as long as possible once you have installed it. To ensure the same, checking the included warranty is always a great idea while choosing the right attic fan thermostat for you. 

While most attic fan thermostats come with either a 1-year long warranty or a 5-year long one, some models may offer a 10-year long warranty or even a lifetime warranty for your peace of mind and much better longevity. 

How Attic Fan Thermostats Work?

Attic fan thermostats are vital for keeping your attic space at the right temperature. They automatically control attic fans based on attic temperature, ensuring a comfortable indoor environment and efficient energy usage.

These thermostats work by detecting changes in attic temperature. When it gets too hot, they activate the attic fan, which then pulls out the hot air, allowing cooler air to come in from outside. This process prevents issues like mold growth, energy waste, and damage to your roof.

A standout feature of attic fan thermostats is their adjustable settings. You can set them to turn on and off at specific temperatures, adapting to different climates and ventilation needs. For instance, in summer, you might want a lower activation temperature for quicker cooling, while in cooler months, a higher temperature helps save energy.

Some thermostats also offer programmable options, letting you schedule when they operate based on your daily routines or energy usage patterns. This level of control helps you save energy while ensuring your attic stays well-ventilated year-round.

Maintenance Tips for Attic Fan Thermostats

To keep your attic fan thermostat working smoothly, follow these maintenance tips:

  • Regular Cleaning and Inspection: Clean the thermostat housing and sensor periodically to remove dust and debris that could affect its operation. Check for any damage, like cracks or loose wires.
  • Test for Proper Functionality: Occasionally test the thermostat to ensure it responds correctly to temperature changes. Adjust the settings manually and observe the fan’s reaction.
  • Battery Replacement (if applicable): If your thermostat uses batteries, replace them as needed to prevent unexpected failures. Follow the manufacturer’s recommendations or replace them when the low battery indicator lights up.
  • Firmware or Software Updates (if applicable): If your thermostat has programmable features or smart technology, check for updates regularly. Updating the firmware can improve performance and add new features.


As you can guess by the name, an attic fan thermostat simply turns on or turns off the fan in your attic depending on the current attic temperature. Such a thermostat not only ensures that your attic stays cool but also saves electricity when a ventilation fan is not needed.

Thus, we have already discussed the best attic fan thermostats earlier in this listicle along with all their important features and specifications.
