HRV works well in cold, dry places by saving heat but not moisture, which stops the air from getting too dry in winter.

ERV is better for humid summers since it moves some moisture with the heat, which helps your AC.

Basically, if indoor moisture goes up in the summer, or if you live in a humid place, ERV is better than HRV at dealing with heat and moisture, which helps to keep your home comfy and saves energy. HRV works fine if humidity isn’t a problem.

Climate Considerations  
-Humid Summers and Cold Winters: ERVs are ideal for climates with high humidity levels, as they can manage both heat and moisture transfer. This makes them perfect for regions with humid summers and cold winters, where controlling humidity is crucial.  
-Cold and Dry Climates: HRVs are suitable for cold and dry climates, where the primary concern is heat recovery. They can help retain warmth in the home while providing fresh air.
