Can I install any smart thermostat with my HVAC system?
No. Compatibility depends on the equipment, wiring, number of stages, accessories, and power requirements. These should be verified first.
Why does the thermostat temperature feel inaccurate?
Placement, airflow, sunlight, wall temperature, calibration, wiring, or equipment operation can affect the reading and comfort.
Can a thermostat cause short cycling?
A thermostat or its placement can contribute to cycling problems, but equipment and airflow issues can cause similar symptoms. Diagnosis should consider the entire system.
