Quality Heating & Air Conditioning Company, Inc. was founded in Wilmington, Delaware in February 1966 by Horace Jr. and Janice Wahl.  Horace served as President of the company and Janice as Secretary.  The first sheet metal job for the company was the Gateway Motel on Route 13 and the first air conditioning job was a house in North Wilmington.  Quality’s original building had approximately 750 square feet and ironically no heat.  By the end of 1966, the company had a mix of residential and commercial industrial work and employed 6 people.

In 1968, Quality moved to a 4,000 square foot building on Church Street in Wilmington, bought more trucks and more sheet metal equipment.  They had 10 employees, 4 trucks and sales of approximately $150,000.

In 1972, the company purchased vacant ground on Brookside Drive in Wilmington and built out 6,000 square feet of office and expanded sheet metal shop space.  Quality won their first big contract to complete all the sheet metal and ductwork for the new Vocational High School in Wilmington as well that year.  In 1973, QH&A became a member of the Delaware Contractors Association, an organization Horace Wahl would later become President of.

In 1984, Horace Adam Wahl, III “Adam” joined his father full time in the company business at age 18.  He had started working in the sheet metal shop at age 8 and worked summers and after school in the shop growing up. Adam worked for many years in the field before assuming the Presidency and majority shareholder position from his father in 2007.  Horace, Jr. retired from the company in 2008 but still acts in an advisory position and is CEO.  

Quality Heating & Air Conditioning, Inc. has grown to over 25,000 square feet of space and 100+ full time employees.  Even with its tremendous success over the years, QH&A remains a small family-owned and operated business, committed to construction safety and excellence.  The company has worked on jobs in Delaware, Maryland, Pennsylvania, Virginia and New Jersey.  QH&A has completed projects at Christiana Hospital, Wilmington Hospital, AI Hospital, University of Delaware, Johns Hopkins Medicine, Baltimore School of Design, Peninsula Regional Medical Center, James Bennett High School, Perdue School of Business, and Dundalk High School to name a few.  

QH&A is a member of the American Society of Heating Refrigeration & Air Conditioning Engineering Association, a charter member of the Associated Builders and Contractors, and the Delaware Contractors Association.  Horace, Jr. was President of the ABC Delaware chapter in 1986 and Adam is currently Treasurer for the Delaware Contractors Association.
