HVAC is an acronym for which phrase?

• A. Hydronic Ventilation Air Cooling
• B. Humidity and Ventilation Air Control
• C. Heat Ventilation and Air Cleaning
• D. Heating Ventilation Air Conditioning

Answer: (D)

The concept being tested is what the acronym HVAC represents in building systems. HVAC stands for Heating, Ventilation, Air Conditioning. This reflects the three core functions: heating to provide warmth, ventilation to bring in fresh air and expel stale air, and air conditioning to cool and dehumidify the indoor air. The other phrases mix in terms not included in the standard acronym—hydronic refers to a water-based method, while humidity control and air cleaning describe related but separate aspects of indoor air quality not represented by HVAC’s three words.
