Direct answer
Room sensors can improve comfort when the thermostat is in an unrepresentative location, but they cannot correct every airflow or building-envelope problem. A compatible system can average selected rooms, prioritize an occupied space, or use a zoning controller to call for conditioned air. If a room has undersized ducts, excessive solar gain, air leakage, a closed damper, or insufficient return path, changing the temperature reference may overcondition another area rather than solve the cause.
Measure temperatures and HVAC behavior over time, inspect airflow and zoning, and confirm how the selected thermostat uses remote sensors. In a Phoenix home, sun exposure can vary sharply by orientation and time of day, so combining room sensing with shades may improve comfort. Preserve equipment safeties and have HVAC-specific faults evaluated by a qualified HVAC professional.
