Replace Existing System Is your conventional furnace or heat pump about to die? Or do you just want to send to the junkyard your inefficient equipment before it breaks your piggy bank? WaterFurnace geothermal products offer the ideal replacement of older or inefficient equipment in the Kalkaska, MI area. Most units are simple 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 almost anywhere. If you have ductwork already installed in your home, you are one step ahead of the game. If not, we can easily 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 warm floors all winter long... We offer a unit that is capable of in-floor heating in association with forced air to provide you with the most comfortable heating possible - all while being a steward of the environment and saving money.
