What to do if Fantech Fan has poor air flows?
- R
  Rebecca WoodAug 4, 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 SHR 1505R Fan supply air feels cold?
- U
  upatelAug 12, 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.

What to do if Fantech SHR 1505R Fan has persistent condensation on window?
- C
  Christina PhillipsAug 17, 2025
  If you notice persistent condensation on windows when using your Fantech Fan, consider the following: * Reduce the desired level of humidity, if there is an improper adjustment of the dehumidistat control, and combine this step with the use of continuous exchange mode. * Have a contractor balance the HRV if the HRV is out of balance. * Open curtains or blinds to improve air circulation near windows.

How to fix HRV and/or Ducts frosting up in Fantech SHR 1505R?
- J
  Jennifer HernandezAug 21, 2025
  If your Fantech Fan's HRV and/or ducts are frosting up, consider these solutions: * Have an HVAC contractor balance the HRV airflows if the HRV air flows are improperly balanced. * Note that minimal frost build-up is expected on cores before the unit initiates defrost cycle functions, if there is a malfunction of the HRV defrost system.

What to do if Fantech Fan air is too dry?
- D
  Daniel WestAug 26, 2025
  If the air is too dry when using your Fantech Fan, increase the desired level of humidity if the dehumidistat control is set too low. Also, change the ventilation mode from continuous mode to standby.

How to fix Condensation or Ice Build Up in Insulated Duct to the Outside in Fantech SHR 1505R?
- J
  jenniferlyonsAug 29, 2025
  To address condensation or ice build-up in the insulated duct to the outside of your Fantech Fan, tape and seal all joints if there is an incomplete vapor barrier around the insulated duct. Also, tape any holes or tears made in the outer duct covering and ensure that the vapor barrier is completely sealed if there is a hole or tear in the outer duct covering.
