An AC thermostat is designed to regulate the temperature in your home by automatically turning your standalone or central AC unit on or off when the desired level is reached.

The type of AC thermostat you need will depend on the system you need to control.

Types of AC Thermostats

There are two main types of AC systems and there are different AC thermostats for each system.

  • Standalone AC units: Including portable ACs, window ACs, floor mounted ACs and mini-split systems.
  • Central & Split AC systems (HVAC systems): Including central ACs, wall mounted ACs and ceiling ACs.

Should I Buy an AC Thermostat

Energy Efficiency

Using smart AC thermostats in your home can significantly lower your energy consumption and bills by up to 40%. When the AC units in your home reach the preset cooling temperature levels, they will be automatically switched off by your thermostat. 

Some thermostats even have sensors for when you are not at home to switch off the AC. During these times, you significantly save up on energy consumption and costs.

Quality of Life

With a thermostat, you will no longer have to silently remain in agony as you freeze through the night. All you need to do is preset the ideal temperature for your room. When that's achieved, the thermostat turns off the AC. 

When the temperature increases, the thermostat turns on the AC. This gives you the freedom to focus on more important tasks or enjoy a good night's sleep.

Remote Control

The best smart AC thermostats can be manually controlled via remote or through their app. The latter option lets you control your thermostat from anywhere using your smartphone, tablet, or laptop. You never have to be in a house that is too cold or hot for you.

AC Thermostat Features to Consider

Scheduling

Some of the best AC thermostats are designed with scheduling features. The scheduling feature lets you preset the climate in your home. For example, during the summer you may choose to preset the temperature at 78 degrees.

As you near bedtime, the temperature settings may be increased or reduced and the same can be done for the time you wake up in the morning. Doing this allows the thermostat to manage the interior climate without having to fumble with the remote frequently.

Temperature & Humidity Sensors  

You will find AC thermostats that are built with both temperature and humidity sensors and controls. These AC thermostats don’t only gauge and control the temperature levels inside your house.

Their operation also takes humidity levels inside your house into consideration for effective temperature control. Additionally, some AC thermostat models can even regulate the humidity inside your home by removing the humid air to enhance precision temperature control.

Geofencing

Some of the best AC thermostats are built with geofencing features. Geofencing is a method of controlling your smart AC thermostats based on your location. Typically, these AC thermostats are designed with preset sensor ranges.

When you are nearby your home or within a 3-mile radius, for instance, the thermostats will switch on the AC. When you leave the house, the thermostats will shut off the AC. This mechanism allows you to save up on energy consumption.

Voice Control   

Smart air conditioner thermostats come with voice control features as well. They can be compatible with systems such as Google Home, Amazon Alexa, and Apple Siri/HomeKit.

This means that you can operate the thermostat and control the temperature through voice controls – the same way you operate your smart home devices. Furthermore, this feature can also be extended to when you are not at home – allowing you to voice control your thermostat wherever you are.

Smartphone App  

Smart AC thermostats are normally designed with proprietary apps. You can access these apps through your smartphone or tablet. These apps are normally compatible with different operating systems such as iOS and Android systems.

Using these apps, you can control your thermostat as well as access several other features such as monthly energy consumption reports. Additionally, with the smartphone app, you can control your thermostat from anywhere you are.

Smart Home Integration

Some AC thermostats feature an even more elaborate and comprehensive design that boosts full smart home integration. This means that your thermostat can integrate with other smart home devices of the same brand.

For example, you can integrate your smart thermostat’s geolocation abilities with your in-home smart sensors for optimum temperature regulation when you are at home, leaving, or returning.

Common Questions About AC Thermostats

How Does An Air Conditioner Thermostat Work?

An air conditioner thermostat regulates the temperature released by your AC unit. These devices are normally preset to your desired temperature levels. 

When the air in the room reaches the preset temperature, the thermostat shuts off the AC. When the room begins to warm up, the thermostat turns on the AC to resume cooling and the cycle continues.

Where Should  An AC Thermostat Be Located In House?

Typically, you want to wall mount your thermostat near the AC in the room that is being cooled (unless your thermostat has multi-room sensors). Additionally, always position your thermostat away from direct sunlight or air vents.

How Much Is An Air Conditioner Thermostat?

The cost of an air conditioner thermostat depends on the model you go for. An air conditioner thermostat will cost you anywhere between $30 and  $300. 

Smart AC thermostats cost at least $150. The more features a smart thermostat has, the more it will cost – at least $200 and above.

The AC Thermostat Verdict

With good quality AC thermostats, you can effectively regulate your interior climate and enjoy a better quality of life. While AC thermostats improve your overall home quality they also help significantly reduce your energy bills.
