Why is my Daikin RCN100HY1(4) airflow so weak and not cooling the room?

  shawchristopherAug 14, 2025
  If your Daikin Air Conditioner's airflow is too slow, or the room isn't cooling enough, several factors could be at play. First, check the air filter; a dirty filter can significantly impede airflow, so clean it. Ensure that all doors and windows are closed to prevent warm air from entering the room. Also, make sure that neither the air suction nor the discharge vents of the indoor and outdoor units are blocked. Finally, verify that the temperature setting is appropriately low.

Why does my Daikin RCN100HY1(4) compressor operate continuously?
- R
  Robert HarrisAug 29, 2025
  If the compressor in your Daikin Air Conditioner runs non-stop, the issue might stem from a few causes. A dirty air filter can cause the compressor to work harder than necessary, so start by cleaning it. Also, check your temperature settings: if you're cooling, the temperature might be set too low; if you're heating, it might be too high. Adjust the temperature accordingly to see if that resolves the issue.

  Bryan BarrySep 2, 2025
  If you notice condensation on the front grille of your Daikin Air Conditioner's indoor unit, it's likely due to air humidity after prolonged use. To address this, try increasing the temperature setting and running the unit at a high fan speed.

Why doesn't the compressor start immediately on my Daikin Air Conditioner?
- M
  matthew02Sep 9, 2025
  If your Daikin Air Conditioner doesn't start the compressor immediately after being turned on, it might be due to a built-in protection mechanism that prevents frequent starts. Wait for approximately 3 to 4 minutes, and the compressor should start automatically.
