New build in 2004 with a 5 ton E series Waterfurnace. We replaced a leaky condenser coil in 2007 but paid nothing due to our 10 year warranty.
Apart from the coil the Unit has run flawlessly for 12+ years. Our house is 2100 square feet but we are conditioning 3800 square feet (including downstairs family room). House is all electric including outdoor hot tub. Winter setting is 70 - summer 78.
Our current monthly (budget billing) is 92/month @ .10 KWH. In all my research most Geo problems are installer issues - not the geo unit itself.
If you are looking to get a new unit find the best installer - not the cheapest price. Very satisfied geo/Waterfurnace customer.
