  • Noisy
  • No heater

The Keystone KSTAT14-2C is one of the best thru wall air conditioners with enough power to effectively cool up to 700 square feet, making it a great option for large rooms. Helping to keep energy bills down, this unit is also Energy Star certified. 

Doubling up with added functions, this wall air conditioner can also act as one of the best dehumidifiers and is capable of removing a maximum of 2.9 pints every hour. 

Keystone KSTAT14-2C: Pricing and value 

The Keystone KSTAT14-2C thru wall air conditioner is good value for money considering the amount of power you’re getting. It offers great performance but this air conditioner doesn’t have a heating option which may be disappointing for some users. 

Since this Keystone wall air conditioner is designed to cool down large spaces, if you’re on a tight budget and don’t need extra power, you may want to consider the Impecca ITAC10-KSA21 instead. The cooling power, measured in BTU, isn’t anywhere near as high as on the Koldfront model, but it should be sufficient for smaller spaces. 

Keystone KSTAT14-2C: Features 

The Keystone KSTAT14-2C offers a lot of handy features considering it’s still fairly priced. There’s a remote control included with this thru wall air conditioner and it has a built-in sensor that can read the temperature of the room. This remote then signals to the air conditioning unit to get to work, ensuring that the temperature is even wherever you are in the room. Because the remote control has a built-in thermostat, you won’t even need to get up in order to adjust the temperature of your room. If you do adjust the Keystone air conditioner and want to go back to your old settings, this clever unit will automatically save your original settings and default back to those whenever you need them. 

When it comes to cleaning this unit, the filter can be easily accessed from the front and quickly slides out so that you can give a clean before placing it back into the machine. When the filter needs cleaning, an alert will sound on your unit so that you know it’s time to take it out and have a look. 

In terms of scheduling, the Keystone KSTAT14-2C has a 24-hour timer so that you can create a cooling routine that suits you. The air flow can be adjusted in four different directions, and you’ll also be able to select from three fan speeds and three cooling speeds. 

If you’re going to be placing the Keystone KSTAT14-2C in your bedroom, you’ll be pleased to know this unit has a night mode that works by slowly increasing the temperature in your room. 

If you’ve found the perfect temperature, there’s also an auto mode that maintains the temperature so that it doesn’t fluctuate.

In addition, the Keystone KSTAT14-2C comes with a one-year parts and labor warranty, but the sealed system is covered by a four-year warranty.
