Why are humidity levels too high with my Lifebreath ERV, causing condensation?

  High humidity levels and condensation with your Lifebreath Fan can stem from several causes. Ensure your dehumidistat isn't set too high by setting it lower. If you have a hot tub or indoor pool, cover them when not in use, as the ERV may not be sized to handle the moisture load. Modify occupant habits to avoid hanging clothes to dry, storing wood inside, and ensure your clothes dryer is properly vented. Vent the crawl space, placing a vapor barrier on the floor of the crawl space. If condensation forms in spring and fall, try increasing the ERV speed.

  To prevent condensation or ice buildup in the insulated duct of your Lifebreath Fan, ensure a complete vapor barrier around the insulated duct by taping and sealing all joints. Additionally, tape any holes or tears made in the outer duct covering, ensuring that the vapor barrier is completely sealed.

  If you're experiencing poor airflow with your Lifebreath Fan, several factors could be responsible. Start by checking and cleaning the exterior hoods or vents, and remove and clean the filter. Ensure the core is not obstructed by cleaning it. Open any closed or blocked house grilles and adjust dampers if installed. Have an electrician check the power supply voltage. Verify the ductwork installation. Increase the speed of the ERV. If the issue persists, have a contractor balance the ERV.

What to do if the supply air from my Lifebreath ERV feels cold?
- J
  Jeremiah BaldwinAug 11, 2025
  If the supply air from your Lifebreath Fan feels cold, consider the following: ensure supply grilles are located high on the walls or under the baseboards, and if ceiling mounted, use diffusers or grilles to avoid direct airflow onto occupants. If the outdoor temperature is extremely cold, turn down the ERV supply speed or consider using a small duct heater (1 kW) to temper the supply air. Also consider placement of furniture or closed doors that may be restricting the movement of air in the home. If supply air is ducted into furnace return, the furnace fan may need to run continuously to distribute ventilation air comfortably.

  Alexander JonesAug 16, 2025
  If your Lifebreath Fan and/or ducts are frosting up, it could be due to a few reasons. Start by having an HVAC contractor balance the ERV airflows. Also, ensure the damper defrost is operating during the self-test, as a malfunction of the ERV defrost system could be the cause.
