Heat Exchanger

I am going to be inspecting a home that my client says there are no exhaust fans in the bathrooms but they have vents connected to a heat exchanger. Should there also be exhaust fans?

Yes, if there is not an operable window.

Is one of the HVAC vents for return air?

It sounds like the bathroom vents are connected to a HRV system, which is fine…no further ventilation needed.

I don’t know I have not seen it yet.
Do you mean a return for the exchanger?

You are right John. I meant air exchanger instead of heat exchanger!:wink:

John is referring to this, or similar. Not used much, if at all, in my area.

Yes I know what they are. Thanks
