The A/C thermostat shall be located where the average temperature is consistent. True or False?

• A. True
• B. False
• C. Not specified
• D. Only in living areas

Answer: (A)

Placing the thermostat where the temperature is representative of the space is essential for accurate control. When it reads a typical room temperature, the system can maintain the desired comfort without over- or under-cycling. If the thermostat sits where the temperature is biased—like in direct sunlight, near a heat source, or in a drafty corner—the reading won't reflect the overall room condition. The result is the AC running too much or too little, causing discomfort and wasted energy. A good location is an interior wall in the main living area, away from sun exposure, drafts, and heat sources, mounted at about eye level. With this placement, the thermostat consistently senses the average temperature, so the statement is true.
