Geothermal with existing high velocity ducts

mike212 Member Posts: 50
My home has standard central air-conditioning that uses high-velocity ducts (small flexible tubes) instead of standard ducts. Full size ductwork would be difficult to install in my home. Radiators are currently used for heating.

I'm interested in installing geothermal if the system would work for heating and cooling using my existing high-velocity ducts. My understanding is that cooling will be no problem but heating may be the issue. Does anyone have experience with a system setup this way?

    I would not do it without checking with the MFG of the Geo unit. I doubt it would work with a standard unit. Maybe they can build you one with a reved up fan.

    Water Furnace makes good equipment
