Local Technicians Pass National “Excellence” Test—Homeowners Benefit
What do you do if you’re a homeowner with a heating or cooling problem but you don’t know a reliable, knowledgeable technician? How do you know if the company you pick really knows what they’re doing?
A national certification test has been developed, and is now being administered, to assure that technicians have the skills to do the job. North American Technician Excellence (NATE) offers these voluntary tests to technician in the areas of heating, ventilation, air conditioning, and refrigeration. The independent, not-for-profit organization is supported by an unprecedented combination of technicians, contractors, manufacturers, distributors, utilities, and heating and cooling contractors.
- Mullen Refrigeration of Latrobe is proud to announce that their Field Personnel have passed the NATE exam. This certification benefits local homeowners by giving them an independent standard by which to select a knowledgeable technician to work on their home comfort system.
- “This certification really helps,” says Roxann Mullen Donahue, Mullen Refrigeration’s President. “It’s a way that we can show our customers that we really care about doing the job right, and that we know how to get it done right the first time.”
- “Heating and cooling contractors today are trying to improve their industry’s image,” says NATE spokesperson Carl Smith. “This certification test is national, independent, focused on current technology, and aimed at a high standard for technicians, so only the best will pass. This encourages all technicians to improve their skills in order to keep up with the pack, and that improves the overall industry for everyone!”

Pride in Our Community
Mullen Refrigeration has been serving the heating and cooling needs of the Latrobe community for over half a century. Our longevity and success have only one source: customer satisfaction, generation after generation.
Pride in Our Products
Because Carrier has always been the world's best-selling brand name, Bob Mullen choose to market Carrier Products exclusively when he began Mullen Refrigeration Service in 1959, and his daughter, Roxann, continues the tradition. At Mullen, we know the finest equipment is only as good as the dealer. The efficiency and performance engineered into furnaces, air conditioners, water heaters, and home comfort systems rely on the dealer's ability to properly select and install equipment to meet the customer's needs.
