Does an air exchanger affect indoor humidity levels?
We built a new home two years ago and having issues with being too dry in the house. Right now today the temperature is 2 degrees outside and the moisture in the house is 22 %
The humidity in your home is largely affected by the humidity levels outside. Happy to help sort this out with you I just need some more info. Where are you located? I assume that '2 degrees' is Celsius not farenheit? If it was 22 % RH inside, do you know what it was outside? Even the most airtight house will still leak air, so in the absence of any mechanical humidity control (like a dehumidifier or an ERV – Energy Recovery Ventilator) the indoor humidity will largely reflect the outdoor humidity. An ERV recouperates moisture but and HRV does not, do you know which you have? And ERV helps maintain humidity levels, while an HRV does not. This page explains how they differ -
Choosing between an HRV and ERV, which is best?
