The company is based in Fort Wayne, Indiana, and its systems are installed in hundreds of thousands of homes across the US. If you've talked to a geothermal contractor, odds are they brought up WaterFurnace — it's the brand contractors point to when they want to show a homeowner this technology is mature and proven.

Common questions about WaterFurnace
How much does a WaterFurnace system cost to install?
A complete WaterFurnace installation — unit, ground loop, and labor — typically runs $25,000 to $50,000 depending on your home size, location, and loop type. The 7 Series is at the higher end of that range. After the 30% federal tax credit, your net cost is roughly $17,500 to $35,000.
What is a WaterFurnace GeoPro dealer?
GeoPro is WaterFurnace's certified dealer program. GeoPro Dealers have completed training and met installation standards. GeoPro Master Dealers are the highest tier — they've completed additional training and have a verified track record. Using a GeoPro Master Dealer is the best way to make sure your system is sized and installed correctly.
How long does a WaterFurnace system last?
The indoor heat pump unit typically lasts 20 to 25 years with regular maintenance. The ground loop, which is the buried pipe, is rated for 50 or more years — effectively the life of the house. This is one reason geothermal has a better lifetime cost than conventional HVAC.
Is WaterFurnace better than ClimateMaster?
Both are top-tier brands and either will serve you well. WaterFurnace has a slight edge in brand recognition and warranty terms on its flagship 7 Series. ClimateMaster's Trilogy 45 has a comparable COP and tends to be a bit more aggressively priced. The bigger factor is usually the quality of the installer, not the brand.
