Why is my Lennox AC running but not cooling?

• Dirty Air Filter: Clogged filters reduce airflow, hindering proper heat exchange. Check and replace it regularly or every 1-3 months as soon as you notice dirty filters or they appear dirty.
• Refrigeration Leak: Low refrigerant levels limit how effectively your system absorbs heat, leading to ice buildup on evaporator coils or hissing sounds indicating leakage that needs professional repair.
• Dirty Condenser Coils: Outdoor unit coils may become clogged with dirt, grass and debris that prevent heat release from the unit. To clean around it and rinse its coils using your garden hose.
• Faulty Thermostat: Wrong thermostat settings or malfunction can thwart cooling efficiency. Make sure the room temperature setting is below your thermostat setting for “cool mode.”
• Blocked Vents or Ductwork: Closed vents, furniture impeding airflow or damaged ductwork can reduce cooling efficiency significantly, so make sure all vents remain open and unobstructed for maximum effectiveness.
• Frozen Evaporator Coils: Ice on indoor coils prevents proper cooling, so switch off and wait until they thaw before restarting your system. This could indicate airflow issues or refrigerant concerns.
• Failed Compressor: Failing compressors often run but fail to compress refrigerant properly and will likely need professional diagnosis and repair in order to function effectively. This typically necessitates professional diagnosis and service in order to resolve.
• Electrical Issues: Malfunctioning capacitors, contactors or wiring may keep components from operating optimally while giving the appearance that everything runs normally.
