  Using water to heat or cool your building is the safest alternative, as hydronic systems can be installed and serviced by any licensed professional contractor. Because other refrigerants are toxic, they must be installed by specially trained technicians. You`ll see those same technicians on expensive service calls installing factory replacement parts because components are not interchangeable with other brands or with different systems offered by the same manufacturer.Many chilled water systems employ chillers...
