Progressive, open minded, and conscientious HVAC installers will have equipment to monitor air quality. Find one who will install some monitoring equipment in your home for a few days. If your house is well built and tight you quite likely have bad air you don't know about. Then you can make a more reasoned decision about the worth of an ERV or HRV. A blower door test may be worthwhile as that will definitively tell you how tight your house is, or isn't. ASHRAE has guidelines about how many air changes an hour your house should have.
There's no need to make an educated guess when there are means available to produce real information.
Hi, thanks for the input. A question: with what type of device does one (HVAC installer) measure air quality? What type of things are measured?
Thanks,
