Horizon Services General Sales Manager John H. Cameron Jr., a giant of the HVAC industry, died suddenly at home on Sunday, Oct. 28, 2018. He was 55.

John was a 1981 graduate of Unionville High School. He served his country as a submariner in the United States Navy from 1983 to 1987 on the USS Skate and the USS Swordfish. John was a true patriot. Each year he proudly participated in Veterans Day celebrations with his daughters, Madeleine and Holly.

As a young boy, John worked in his family's heating and air conditioning business, John H. Cameron and Sons. He worked in the company in different capacities until he found his true calling, sales. After his father sold the family business, John went on to work for Conectiv Services in Wilmington, Delaware (1996 to 1999), and then Service Experts in Danbury, Connecticut, in 1999. From 2000 to 2009 he was a salesman for Oliver Heating and Cooling in Morton, Pennsylvania. In 2009, John joined Delaware-based Horizon Services as sales manager during a time of incredible growth.

John was a key member of Horizon's executive management team, and led its expansion in Pennsylvania and New Jersey. Additionally, he was directly involved in the development of the Horizon sales process: building sales teams and determining the direction and culture of Horizon's Comfort Consultants.

In 2019, Horizon Services established an award in John’s name to honor his significant impact on the HVAC industry as well as the company's culture.

"John created a legacy renowned throughout the country," said Dave Geiger, founder and CEO of Horizon Services. "He was an integral part of so many achievements. His loss is felt in every corner of the company, from our call centers and warehouses to teams in finance and marketing."

John was well known and respected in the HVAC industry throughout the United States. His professional affiliations include Sandler Sales Corp. President's Club, the International Ground Source Heat Pump Association, Home Depot HVAC Sales Boot Camp and extensive Dale Carnegie Courses.

John was a cherished friend to all who were fortunate enough to know him. His charm, hard work ethic, and unique ability to inspire others will be his legacy. John was a diehard Eagles and Phillies fanatic, a classic car enthusiast, and a Rolling Stones fan. He especially enjoyed sharing a glass of Laphroaig Scotch with close friends. John was a 32nd Degree Scottish Rite Mason, Shrine Noble, and past member of St. Andrew's Society of Philadelphia. He was a proud past member of the Longwood Rotary Club and would have liked to have remained an active member if not for the increasing demands of his job. John loved World War II history, was proud of his Scottish heritage, and had a thirst for knowledge. He was always looking for his next non-fiction or leadership audiobook for his many hours on the road. John was dedicated to daily exercise and loved going to the gym. While he was committed to many things, it was clear to everyone who knew him that there was nothing more important than his wife, Karen, and their daughters, Madeleine Ava and Holly Grace.

John was the beloved husband of Karen Kayatta Cameron with whom he shared 20 years of marriage. He was the son of Marilyn "Bunny" Murphy Cameron of Oxford, Pennsylvania, and John H. Cameron, Sr. and his wife, Glenda, of Palm City, Florida.

In addition to Karen, Madeleine, and Holly, John is survived by his father-in-law and mother-in-law, Dr. Jerome and Mary Grace Kayatta; his sister-in-law and brother-in-law, Lynne and Dominic Kayatta; his sister-in-law and brother-in-law Kristen and Gary Pierce; his brother Drew and his partner Kim Nashed; his sister Heather and her husband Rick Treml; as well as seven nieces and nephews: Sophia, Nicholas, Emily, Andrew, Amanda, Paige and Tyler.

John was predeceased by his brother Ron in 2006.

Family and friends celebrated John's life on Saturday, Nov. 10, 2018, at the Mendenhall Inn, Mendenhall, Pennsylvania. The memorial service included full military honors.
