    How to fix condensation or ice build up in insulated duct to the outside of Fantech SHR 2004 Fan?
    • J
      jlandrySep 22, 2025
      If you notice condensation or ice build-up in the insulated duct to the outside of your Fantech Fan, it might be caused by an incomplete vapor barrier around the insulated duct. In this case, tape and seal all joints. Another cause can be a hole or tear in the outer duct covering, tape any holes or tears made in the outer duct covering and ensure that the vapor barrier is completely sealed.

    Why is the air from my Fantech SHR 2004 too dry?
    • A
      Adam AlexanderAug 25, 2025
      The air from your Fantech Fan may be too dry if the dehumidistat control is set too low or the HRV is out of balance. You can increase the desired level of humidity and change the ventilation mode from continuous to standby. It is also recommended to have a contractor balance the HRV airflows.

    What to do if Fantech SHR 2004 Fan has poor air flows?
    • J
      Joshua BrownAug 26, 2025
      If your Fantech Fan has poor air flows, you can try the following: * Clean exterior hoods or vents if the 1/4" (6mm) mesh on the outside hoods is plugged. * Remove and clean the filter if filters are plugged. * Remove and clean the core if it is obstructed. * Check and open indoor grilles if they are closed or blocked. Also, ensure that an electrician checks the supply voltage if there is an inadequate power supply at the site and check duct installation if ductwork is restricting airflow. Increase the speed of the HRV if there is an improper speed control setting. If the HRV airflow is improperly balanced or ducting has fallen down or been disconnected from the HRV, have a contractor address these issues.

    Why is my Fantech Fan supply air feels cold?
    • M
      michaeloliverAug 27, 2025
      If the supply air from your Fantech Fan feels cold, it could be due to the following reasons: * The location of supply grilles may be causing airflow to irritate occupants. Relocate the grilles high on the walls or under the baseboards, and install ceiling-mounted diffusers or grilles to avoid directly spilling supply air on occupants. You can also turn down the HRV supply speed. A small duct heater (1kW) could be used to temper the supply air. Ensure that furniture placement or closed doors are not restricting air movement. * If the outdoor temperature is extremely cold, and supply air is ducted into the furnace return, the furnace fan may need to run continuously to distribute ventilation air comfortably.

    • L
      Logan ClarkSep 23, 2025
      If the LED on your Fantech Fan is flashing, it indicates that no power is being transmitted to the control board. First, make sure the unit is plugged in. If it is, the transformer may need replacing.

    Why does the supply air feel cold from my Fantech SHR 2004 Fan?
    • M
      morenobrandonSep 12, 2025
      If the supply air from your Fantech Fan feels cold, it could be due to the location of the supply grilles, which might irritate the occupant. Consider relocating the grilles higher on the walls or under the baseboards, or install ceiling-mounted diffusers or grilles to avoid directly spilling the supply air on the occupant. You could also turn down the HRV supply speed or use a small duct heater (1kW) to temper the supply air. Additionally, ensure that furniture or closed doors aren't restricting air movement in the home. If the outdoor temperature is extremely cold, and the supply air is ducted into the furnace return, the furnace fan may need to run continuously to distribute ventilation air comfortably.

      If the supply air from your Fantech Fan feels cold, reposition the supply grilles high on the walls or under the baseboards, and install ceiling-mounted diffusers to avoid direct airflow on occupants. Reduce the HRV supply speed. If supply air is ducted into the furnace return, run the furnace fan continuously. Also, ensure furniture or closed doors aren't restricting air movement.

    How to improve poor air flows in my Fantech SHR 2004?
    • K
      Krystal TaylorSep 1, 2025
      To improve poor air flows with your Fantech Fan, begin by cleaning the exterior hoods or vents and removing and cleaning the filter and core. Ensure indoor grilles are open and not blocked. Have an electrician check the power supply voltage. Check the duct installation and increase the HRV speed. If the issue persists, have a contractor balance HRV airflows or reconnect ducting.
