Regular maintenance for the Lennox 15CHAX includes cleaning or replacing air filters every 1-3 months, checking refrigerant levels, inspecting electrical connections, and ensuring the outdoor condenser coil is free from debris.

Common error codes on the Lennox 15CHAX include E1 (sensor failure) and E2 (communication error). Resetting the system can sometimes resolve these issues. Persistent problems should be assessed by a professional.
Air filters should be checked monthly and changed every 1-3 months, or more frequently if the unit is in constant use or located in a dusty environment.

To clean the outdoor condenser coil, turn off the power to the unit, remove any debris, and use a soft brush or vacuum to clean the fins. For deeper cleaning, use a garden hose to gently wash the coil, avoiding high pressure.
Improve energy efficiency by regularly maintaining the unit, sealing ductwork, using a programmable thermostat, and ensuring windows and doors are well-insulated.
