Cold Climate version of ERV/ HRV for Climate Zone 5A?
I’m in the process of purchasing a home that’s located in climate zone 5A. I’ve been looking at HRVs and ERVs however I can’t seem to find a clear answer about whether we should be using a model specifically marketed for Cold Climates. I’ve reached out to local HVAC folks, however no one seems particularly familiar with the nuances of balanced ventilation since exhaust-only is the standard in our neck of the woods.
Is 5A “cold enough” to warrant the Cold version of an HR/ERV?
A few details about the house/project: 2000′ SF colonial. Double pane windows, but otherwise typical mid 1970’s construction. Central Air/Forced Air Heat.
Thanks in advance.
