- zip1234 6y agoAs far as I know they only put them in the super expensive houses that are made extremely tight. If they use spray foam insulation then there is very little air circulation so that they need to add an ERV just to get enough air to breath.
- sjg007 6y agoCheck your code requirements. I am in the USA and they are required, but I am in the north where we have very cold winters and humid summers. You should consider putting one in if you don't have one.
- exhilaration 6y agoI'm in Pennsylvania! But maybe that's not north enough for them to be required.
