I purchased a Earth Outdoor Furnace from Dave Gideon and I absolutely love the furnace, however I recently discovered that most of the fittings that were installed on the water heater side of my furnace connections are leaking and have been for the last several months, I am not sure of the floor damage under the water heater, I noticed mold on the wall in the adjacent room. I have tried to contact both Dave (the owner) and his son Jonathan for approximately 2 weeks and they never take my phone calls, never call back, never answer text. I would definitely reccomend the product but if this is the kind of customer service Dave's Construction has than steer clear and find someone else to handle your construction needs! Oh by the way I paid like $3200.00 for this installation and I thought there would be some kind of service after the sale, but not with this company obviously! Do not use this company!!!
