Why is my Lennox VRF VELD024N432U not cooling well?
- R
  Robert MackAug 11, 2025
  Several factors can cause a Lennox air conditioner to have a poor cooling effect. The filter might be dirty, so try cleaning or replacing it. There might be too many people or heat sources in the room, so reduce them. Ensure all doors and windows are closed. Check that the inlet and outlet of the indoor unit are not blocked. The temperature setting may be too high, so lower it. Finally, the refrigerant level might be insufficient; in this case, contact an authorized service center.

  If your Lennox air conditioner won’t start, first check the power connection. If that's not the issue, reset the circuit breaker, as it may have tripped due to an electrical leak. Also, check the input voltage to ensure it's adequate. If none of these steps work, there may be a defect in the main PC-board, and you should contact an authorized service center.

  A poor heating effect in your Lennox air conditioner can be due to several reasons. The filter might be dirty, so clean or replace it. Make sure all doors and windows are closed. The set temperature could be too low, so increase it. If these don't help, the refrigerant level might be insufficient, requiring you to contact an authorized service center.

What to do if my Lennox VRF VELD024N432U stops running after a while?
- A
  Alyssa TorresAug 29, 2025
  If your Lennox air conditioner stops after running for a while, check if the inlet or outlet of either the outdoor unit (ODU) or indoor unit (IDU) are blocked. Remove any obstacles to ensure proper airflow.

Why doesn't the indoor fan start up during heating in my Lennox Air Conditioner?
- M
  Meghan HillSep 4, 2025
  The indoor unit (IDU) fan might not start immediately during heating in your Lennox air conditioner because it waits until the heat exchange becomes hot to prevent delivering cool air. Allow the system time to heat up. Also, if the system is defrosting, the IDU fan may stop temporarily to prevent delivering cool air and will resume after defrosting is complete.
