Rob Bollinger

Part Owner – ABC Radiator

My name is Rob Bollinger, part owner and operator of A.B.C. Radiator and A/C located in Baltimore, Maryland. I have been working on automotive and heavy-duty A/C systems for over 20 years. A.B.C. Radiator and A/C is a family business which was started by my grandfather in 1970.

We provide the sales, service, and installation of all forms of transportation. Fun fact: we are the last place in Baltimore City to still repair are core radiators! We are the “best place in town to take a leak”. Coming from a family business gives me great pride in the work I do, and I am grateful for the relationships made over years with our customers and the local businesses.

Outside of the shop I am with my family… I have a beautiful wife and three amazing kids. In the morning while the family is still sleeping you can find me in the gym weightlifting. (It’s the best way to start the day!) In 2020 I was very happy to receive the young ambassador award at the training and convention show in Nashville. I hope to continue to be involved with the MACS organization for many years to come. Being a member has been a great asset to my company.

Peter McArdle

Retired – Standard Motor Products

Following a thirty-year career with Standard Motor Products, Peter recently retired as a sales and technical instructor and content developer at the company’s corporate training center in Irving, Texas. He has participated in several ASE test writing workshops for air-conditioning and has presented at MACS Annual Conference for almost twenty years.

When Peter moved to the training center, the aftermarket faced many challenges due to the difficulties associated with the industry transition from R-12 to R-134a. This period marked a turning point, successfully repairing R-134a systems required far greater precision and understanding. In response to this, Peter developed new and persuasive training content that addressed these new challenges to be shared with the industry.

Peter hopes that his experience developing and delivering training content, and understanding the firsthand experience of technicians repairing automotive air-conditioning systems, can help provide relevant input to the board in the area of technician education.
