"The contractor says if I don't like the noise, don't use the HRV..."

Comment from a homeowner following John Bleasby’s recent articles on Passive Houses…
We have just built a house to passive house standards and have put a balanced ventilation system in. I can not tolerate the sound that the HRV makes. The ducting in the house carries the sound of the motor through the house and also transmits sound from one room to another. There must be a system out there that does not make such a noise? The contractor says if I don’t like the noise don’t use the HRV. BUt as your diagram indicates an HRV is essential to a super insulated home.

Eve: I’d get your mechanical contractor in to have a look. My HRV unit is suspended on straps from the joists above, so the unit cannot reverberate against any stud walls. Is yours? Also, your unit should have variable speeds you can program from the master keyboard; maybe yours is set for a high speed, hence the noise? Just some random thoughts. The HRV should not be so noisy as to bother you!
