  An AC not cooling usually stems from simple fixes like a dirty air filter, blocked vents, or wrong thermostat settings, but can also signal serious problems like low refrigerant (due to leaks), a dirty condenser/evaporator coil, a faulty fan/compressor, or leaky ductwork, all hindering heat transfer or airflow for proper cooling.  

 Your AC Unit keeps freezing, usually because of restricted airflow (dirty filter, closed vents, fan issues) or low refrigerant (leak), which causes the evaporator coil to get too cold and ice up. Simple fixes include replacing the filter and opening vents, but persistent freezing points to a leak or mechanical problem needing a professional.  

 An AC blowing warm air usually signals issues like a dirty air filter, low refrigerant (due to a leak), a frozen evaporator coil, a malfunctioning compressor, or dirty condenser coils, all preventing proper heat exchange; also check simple things like thermostat settings. Common culprits include airflow restriction (filter, coils), refrigerant problems, or component failure in the outdoor unit.  

 An outdoor unit not running is usually caused by power issues (tripped breaker, bad disconnect), a failed , a bad contactor, low refrigerant, a dirty condenser coil, or a faulty fan/compressor motor, often triggered by a safety switch due to a clogged drain line or dirty filter. Start by checking power and thermostat settings, but for internal component failures like capacitors or motors, professional help is usually needed.  

Your AC could cause high electric bills mainly by working too hard due to lack of maintenance (dirty filters, coils), system issues (low refrigerant, failing parts, leaky ducts), or inefficiencies from old equipment, poor insulation, and extreme outdoor heat, forcing it to run longer and use more power to cool your home. Simple changes like regular filter changes, sealing leaks, and proper thermostat use significantly reduce this energy drain.  

 A blank thermostat screen usually means a power problem, often from dead batteries (for battery models), a tripped circuit breaker/blown fuse, or a safety switch (like a full drain pan) cutting power to the HVAC system, but it can also be caused by loose/damaged wiring, a bad transformer, or a failed thermostat component. Start by checking batteries and breakers, ensuring the furnace door is closed, and inspecting for loose wires; if those fail, a professional might be needed to check internal components.
