Replace Existing System Is your classic furnace or heat pump about to die? Or do you just want to get rid of your inefficient equipment before it costs you an arm and a leg? WaterFurnace geothermal products provide the ideal replacement of older or inefficient equipment in the Rochester, MN area. Most units are easy to install and can be installed in areas unsuitable for fossil fuel furnaces. There is no combustion or need to vent exhaust gasses which means our equipment can be installed virtually anywhere. If you have ductwork already installed in your home, you are starting the race ahead of the pack. If not, we can simply install ductwork so you can enjoy the comfort of geothermal to its full extent. Another heating method to consider is radiant in-floor heating. Imagine walking on heated floors all winter long...
