In the beginning, they performed well, especially with regard to technical knowledge. I purchased thousands of dollars on a complete water treatment system and also ductless splits. After they had my money, customer service became terrible. Today I was charged nearly $500 for a major component that had failed in the water treatment system, 18 months old!. A part that should have been galvanized to protect against corrosion. This business does NOT honour it's highly advertised warranties.
