Why does the supply air from my Fantech SER feel cold?
- K
  Kevin GainesAug 12, 2025
  If the air from your Fantech Fan feels cold, it might be due to the location of the supply grilles, causing airflow irritation. To resolve this, relocate the grilles higher on the walls or under the baseboards, or install ceiling-mounted diffusers/grilles to avoid direct airflow onto occupants. You can also turn down the ERV supply speed. For extremely cold outdoor temperatures, if the supply air is ducted into the furnace return, ensure the furnace fan runs continuously to distribute ventilation air comfortably. Also, consider that furniture placement or closed doors might be restricting air movement in the home.

  If you're experiencing poor air flows with your Fantech Fan, several factors could be responsible. Start by cleaning the exterior hoods or vents if the 1/4" (6mm) mesh is plugged. Also, remove and clean the filters and core. Ensure indoor grilles are open and not blocked. Have an electrician check the supply voltage if there's inadequate power. Inspect the duct installation for any restrictions. Increase the ERV speed (from REDUCED to NORMAL). If the issue persists, have a contractor balance the ERV air flows and reconnect any ducting that has fallen down or disconnected from the ERV.

What to do if the air is too humid with my Fantech Fan?

  Katherine Armstrong MDAug 20, 2025
  To address excessive humidity with your Fantech Fan, start by reducing the desired humidity level using the dehumidistat control. Combine this with continuous exchange mode. If there's a sudden temperature change, wait for it to stabilize, as heating can also help. Store the majority of your wood outside to reduce moisture. Ensure your dryer vent exhausts outside. Open curtains or blinds to improve air circulation near windows. If you have a well-sealed basement door, open it or install a grill. Finally, check the defrost damper, and if it's blocking fresh air, have a contractor verify the damper system.

  If you notice condensation or ice buildup in the insulated duct of your Fantech Fan, ensure there isn't a hole or tear in the outer duct covering. Tape any holes or tears and verify the vapor barrier is completely sealed. Also, tape and seal all joints to ensure a complete vapor barrier around the insulated duct.

Why is my Fantech Fan ERV and/or ducts frosting up?
- X
  xbowmanAug 28, 2025
  If your ERV and/or ducts are frosting up, the ERV air flows may be improperly balanced. In this case, have an HVAC contractor balance the ERV air flows. Also, note that minimal frost build-up is expected on cores before the unit initiates defrost cycle functions and it might indicate a malfunction of the ERV defrost system.

  Antonio LeonardSep 4, 2025
  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 the ventilation mode from continuous to standby.
