Which program includes A/C tune-ups and other efficiency measures?

The HVAC Program focuses specifically on heating, ventilation, and air conditioning systems, which includes A/C tune-ups and measures aimed at improving the overall efficiency of these systems. By tuning up air conditioning units, the program helps ensure optimal performance, which can lead to energy savings, reduced utility bills, and prolonged equipment life. Additionally, HVAC efficiency measures often encompass other aspects of residential and commercial climate control, including insulation and duct sealing, thus providing a comprehensive approach to improving energy efficiency.

In contrast, programs like Green Power Sources are generally aimed at promoting renewable energy solutions rather than the efficiency of existing systems. The Refrigeration Program is more focused on systems specifically designed for cooling and preserving food and other perishables, which may not include general air conditioning. The Efficiency Lighting Program targets lighting systems to enhance energy savings but does not cover HVAC systems or their maintenance. Therefore, the distinction of the HVAC Program as the correct answer lies in its dedicated focus on the maintenance and efficiency of heating and cooling systems specifically.
