ERV retrofit ductwork old house
I want to try to install the duct work myself on an ERV in our 1915 bungalow 1600sqft not including basement zone 5 outside of Boston house. I’ve been monitoring CO2 levels and they’re up to 2k ppm in bedrooms (door has to stay closed in our nursery).
I cannot find any “how tos” or articles on GBA/FHB on actually performing this work, meaning getting the duct work into the walls and passing it up to the second floor from an unfinished (finished in the future) basement. We have no chases or current ductwork and have ductless units. From what I’ve read the options are some sort of flex duct similar to zehnder, oval or rectangular. How can I do this work without completely taking down a whole lot of sheet rock?
