Keystone Sales & Associates is now the sole manufacturer representative of Bosch plumbing and HVAC products in the Carolinas.

Bob Della Sala, Keystone’s president and owner, said Bosch chose Keystone for its customer service reputation.

“This is an exciting time for Keystone Sales & Associates,” said Della Sala. “By expanding our Mid-Atlantic footprint to the Carolinas, we are now able to touch more customers on a regular basis with our unique value-add, educational approach. And, with our exclusive relationship with Bosch, I can think of no better way to enter this highly competitive market.”

The Bosch products Keystone will sell to contractors include water heaters, wall-hung boilers, geothermal HVAC systems, high-efficiency heat, controls and accessories.

Keystone will provide customer training on Bosch products and promote the company’s T9000 tankless water heaters and Inverted Ducted Split heat pump units, officials said.

“Commercial jobs require superior performance and reliability, which is why professionals trust Bosch. And it’s for the same reasons Bosch chose Keystone,” said Della Sala.
