Lennox calls we see often start with thermostat compatibility, modulating control signals, and flame sensor soot on gas models. A new thermostat that is not set up for the furnace type can cause short cycling, even when the furnace itself is sound.
Our Lennox visit checks thermostat settings and signal first, then ignitor, flame sensor, burners, and airflow. For modulating models, we check that the control is staging heat correctly, not just that it turns on and off.
For warranty questions, see our manufacturer warranty page. Terms depend on model, serial number, and registration. We service Lennox units as an independent repair service, not as an authorized dealer.
