More About Us
Increase your SSI, PROSTOCK
parts and supplies can help
Mar-Hy Distributors' Prostock Parts Department is based on a "cradle-to-grave" Equipment Life Cycle Strategy for HVAC parts and supplies. This strategy allows us to support our contractors by helping them reduce the cost of carrying inventory.

Even though Ruud and other HVAC products are designed for minimum service, some service is still needed. The ability for the contractor to quickly order from a large range of parts will increase the Service Satisfaction Index (SSI).

The SSI is the satisfaction score for any key service function at any point in time. The Prostock Parts Department will help you with many of these factors.
