Why Keystone KSTAW08INV-HC Air Conditioner air is not cold enough?
- K
  Katherine LaraAug 17, 2025
  If the air from your Keystone air conditioner isn't cold enough, several factors could be the cause. If the room temperature is below 60°F (16°C), cooling may not occur until the room warms up. Check if the temperature sensor behind the air filter is touching the cold coil and try to move it. Set the unit to a lower temperature. If you've just changed modes, wait 3 minutes after setting it to the COOL mode for the compressor to start. Finally, check for and clear any obstructions blocking the outdoor intake/exhaust.

Why is my Keystone KSTAW08INV-HC Air Conditioner making noise when cooling?

  When your Keystone air conditioner is cooling, it is normal to hear the airflow. If it is too loud, set to a slower FAN setting. If you notice window vibration, it may be due to poor installation. Refer to the installation instructions or check with the installer.

  When your Keystone air conditioner starts, a “da-da” sound may occur for about thirty seconds due to the compressor starting. This is normal.

How to fix a Keystone KSTAW08INV-HC Air Conditioner that does not start?
- C
  Charles SotoAug 26, 2025
  If your Keystone air conditioner doesn't start, there are several possible causes. First, ensure the wall plug is firmly pushed into the outlet. If that's not the issue, check your house fuse or circuit breaker; replace the fuse with a time-delay type or reset the breaker. Also, check the Plug Current Device and press the RESET button. Finally, make sure the power switch is turned ON.

What to do if Keystone KSTAW08INV-HC Air Conditioner is cooling, but the room is too warm with no ice forming?
- C
  Carol OwenAug 28, 2025
  If your Keystone air conditioner is cooling but the room remains too warm and there's no ice forming on the cooling coil, consider these possibilities: Check and clean the air filter if it's dirty or restricted. Ensure the temperature isn't set too high by setting it to a lower setting. Adjust the air directional louvers for better air distribution. Make sure drapes, blinds, or furniture aren't blocking the front of the unit. Close any open doors, windows, or registers that may be letting cold air escape. If the room is very warm, allow extra time for the unit to remove stored heat from walls, ceiling, floor and furniture.

What to do if Keystone air conditioner is cooling, but the room is too warm and ice is forming?

  Douglas MorrisAug 31, 2025
  If your Keystone air conditioner is cooling, but the room is too warm and ice is forming on the cooling coil, it could be due to a few reasons. If the outdoor temperature is below 64°F (18°C), set the unit to FAN ONLY mode to defrost the coil. A dirty air filter can also cause this issue, so clean it. If the thermostat is set too cold for night-time cooling, use FAN ONLY mode to defrost the coil, and then set the temperature to a higher setting.

Why does my Keystone KSTAW08INV-HC Air Conditioner turn on and off rapidly?
- J
  James SotoSep 2, 2025
  If your Keystone air conditioner is turning on and off rapidly, the issue might be a dirty or restricted air filter, so clean it. If the outside temperature is extremely hot, set the FAN speed to a higher setting. Also, check for any obstructions blocking the outdoor intake/exhaust and clear them.

- V
  Vicki HintonSep 5, 2025
  If the remote sensing is deactivating prematurely on your Keystone air conditioner (on some models), make sure the remote control is within 20 feet and pointed towards the unit. Also, ensure there are no obstructions blocking the remote control signal.

Why is my Keystone KSTAW08INV-HC dripping water outside?
- S
  Stephanie WrightSep 8, 2025
  If water is dripping outside when your Keystone air conditioner is cooling, it is normal during excessively humid days, as the unit is removing a large quantity of moisture from the room.

Why is my Keystone air conditioner dripping water inside?

  If water is dripping inside when your Keystone air conditioner is cooling, it may be due to improper installation. Tilt the air conditioner slightly to the outside to allow water drainage. Refer to the installation instructions or check with the installer.
