  To improve poor air flow in your Fantech Fan, consider 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 it's plugged. - Remove and clean the core if it's obstructed. - Check and open indoor grilles if they are closed or blocked. - Have an electrician check the supply voltage if there's an inadequate power supply at the site. - Check duct installation if the ductwork is restricting airflow. - Increase the speed of the HRV by changing the unit control from REDUCED to NORMAL speed if the speed control setting is improper. - Have a contractor reconnect ducting if it has fallen down or been disconnected from the HRV. - Have contractor balance HRV airflows if HRV airflow improperly balanced.

Why is there persistent condensation on the window with my Fantech SHR?
- K
  Kristen LamAug 20, 2025
  Persistent condensation on windows when using your Fantech Fan can be due to a few reasons: - The dehumidistat control may be improperly adjusted; reduce the desired level of humidity and combine this step with the use of continuous exchange mode. - There might be poor air circulation near the windows; open curtains or blinds to improve airflow. - The HRV might be out of balance; have a contractor balance the HRV.

Why does the supply air from my Fantech SHR Fan feel cold?
- C
  Carla VaughanAug 25, 2025
  The supply air from your Fantech Fan might feel cold due to: - Poor location of supply grilles, the airflow may irritate the occupant. Locate the grilles high on the walls or under the baseboards, install ceiling mounted diffuser or grilles so as not to directly spill the supply air on the occupant (e.g., over a sofa). Turn down the HRV supply speed. A small duct heater (1kw) could be used to temper the supply air Placement of furniture or closed doors is restricting the movement of air in the home. - Extremely cold outdoor temperatures. If the supply air is ducted into the furnace return, the furnace fan may need to run continuously to distribute ventilation air comfortably.

  If the air is too dry when using your Fantech Fan, it might be because the dehumidistat control is set too low. Increase the desired level of humidity and change ventilation mode from continuous mode to standby.

What to do if my Fantech SHR Fan HRV and/or ducts are frosting up?
- B
  Benjamin DavisSep 1, 2025
  If your Fantech Fan's HRV and/or ducts are frosting up: - Have an HVAC contractor balance the HRV airflows, as improperly balanced HRV air flows can cause frosting. - Note that minimal frost build-up is expected on cores before the unit initiates defrost cycle functions, which could also be related to a malfunction of the HRV defrost system.

  Condensation or ice build-up in the insulated duct to the outside of your Fantech Fan could be due to: - An incomplete vapor barrier around the insulated duct; tape and seal all joints. - 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.

What to do if my Fantech Fan makes the air too humid?
- J
  John TaylorNov 16, 2025
  If your Fantech Fan is making the air too humid, try the following: - Reduce the desired level of humidity, as the dehumidistat control may be set too high, combine this with the use of continuous exchange mode. - Wait until the outside temperature stabilizes (especially in winter), as a sudden change in temperature can cause humidity. Heating will also improve the situation. - Store the majority of your wood outside, as storing too much wood for heating can increase humidity. Even dried, a cord of wood contains more than 20 gallons of water. - Ensure the dryer vent is exhausting outside, as a dryer vent exhausting inside the home can increase humidity. - Open curtains or blinds to improve air circulation near windows, as poor air circulation can contribute to humidity. - Open the door or ...
