My wife and I are planning on building a new house in Southeast Wisconsin (Milwaukee area.) We are strongly considering having an HRV unit installed to circulate fresh air into the tightly sealed new construction home.
We are not particularly interested in getting a variable speed fan on the furnace. We're not the type that run the furnace fan all the time in the winter, (we disagree whether to run it all the time in the summer )
The question is: Is it a good or bad idea to install an HRV unit with a traditional (non-variable speed, not sure what to call it) furnace? I understand that the HRV has a separate fan from the furnace (right?) and I don't quite understand what is going to happen when one is on and not the other. Are the two fans synched together? What does the HRV do when the furnace fan is completely off? What does the HRV do when the furnace fan is on but the furnace/AC is not actively heating/cooling? Do we have to remember to switch on the HRV at the thermostat or is that automated? What is the recommended usage pattern in the summer and winter?
We would greatly appreciate any insight and/or advice from the experts on the forum.
