Jasper is a first-line manager at a heating and HVAC company. Although he no longer goes out to customers' homes and does their repairs, since he worked in the field for over 20 years, he is able to train employees, answer questions, provide guidance, and solve problems. These abilities most closely describe his

technical expertise

Explanation:

technical expertise refers to the high level of knowledge acquired (usually through work experience) about some type of technology or technical work. For example, a mechanic that has repaired cars for more than 30 years would be considered to have technical expertise.
