DALLAS - Mitchell Enterprises Inc. has returned as an HVAC wholesale representative firm for venting-products maker Selkirk LLC in Texas and Oklahoma.

Because they represented Selkirk in the past, Mitchell's familiarity with the products should help them get a quick start, the company said. Based in Dallas, with an additional office in Houston, the firm employs three inside personnel and 4 outside salespeople, and has plans to add additional personnel to the outside sales force.
