  • GSHH3K is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Versatile and reliable, the Broan GSHH3K quietly refreshes the air and gives us a high degree of confidence that the air we are breathing is healthy. We installed our Broan GSHH3K upon the advice of an environmental specialist. It was recommended , in part, because our house is so airtight. The installation process was a bit challenging for our contractor, but we eventually got it in correctly. We have found it easy to use and maintain, and the techs at Broan have been very helpful in response to questions. We can tell the difference in the quality of the air. We have two dogs in the house, and you can hardly tell. We ask people who come inside whether it smells "doggy," and they say that it smells fresh and clean. We highly recommend this product.

    Rated 5 out of 5 by from This product has helped us with respiratory issues We have been satisfied with the Broan GSHH3K unit so far, since we purchased it 9 months ago. My wife had respiratory issues before we moved in and so we installed this unit in hopes that it would help with her problem. In nine months she has not had one respiratory issue, where as the previous year, in a different location, she was ill at least 6 times over a twelve month period. I can not say that this is the main reason for the improved health, bit this is the only item related to air exchange that has been added to her environment. For anyone wanting better air quality in their homes I would recommend this unit.

    Rated 5 out of 5 by from So far so good. I installed this air exchanger last fall. My home didn't have one except for the upstairs bathroom fan with a switch in the basement. I've only had it about 6 months but there isn't anything to complain about yet.

    Does my furnace motor need to run at all times while in the auto mode?

    My installer told me the furnace motor has to be on run, not auto, while my GSHH3K is in the auto mode. Is this the case?
    Asked by: George
    Thank you for your question on the GSHH3K. For best performance and to get the most out of your unit, it would be recommended that your furnace be running for maximum benefits. Please contact our Technical Support Department directly at 800-637-1453.

    We have a GSHH3K in our earth-sheltered home and are very happy with the product. We would like to have a spare fan powered by a 12vdc motor ...

    ...for a future time when we go off the grid (either by choice or otherwise) Is that a part you might consider providing in the future?

    Does the unit provide positve pressure inside the home? Would it be considered a makeup air unit for direct vent appliances (assume outdoor temp +32F)

    I have a newer home built in 2010. I'm interested to know if I require an additional make up air unit to provide "positive" pressure inside the home, so that the air to air unit, or other direct vent appliances do not cause a problem with depressurizing the house. I have a Geothermal furnace, so that is not a concern, however the various powered bath vents and range hood and a direct vent hot water heater do exhaust air with out a direct means of replacing it. Is this unit designed to provide a slight positive pressure in the home so that the occasion use of a powered vent does not draw air thru window or other unfiltered cracks in the building envelope?
