Understanding Your LG Air Conditioner 24 Hour Ac Company Fix My Air Conditioner Commercial Ac Service Near Me
Before diving into repairs, it’s essential to understand the basics of how your LG AC unit works. Most LG ACs are either window units, portable units, or central air conditioning systems. Regardless of the type, the core components and their functions remain similar: Emergency Heating Repair Near Me Ac Repair Man Near Me Commercial Air Conditioning Service Near Me
- Compressor: The heart of the AC system, the compressor pumps refrigerant, a special fluid, through the system, increasing its pressure and temperature.
- Condenser: Located outside, the condenser releases the heat absorbed by the refrigerant into the outside air, cooling the refrigerant back into a liquid.
- Evaporator: Located inside, the evaporator absorbs heat from the indoor air, cooling the room.
- Refrigerant: A special fluid that absorbs and releases heat, circulating throughout the system.
- Expansion Valve/Metering Device: Controls the flow of refrigerant into the evaporator.
- Fan Motors: Circulate air over the condenser and evaporator coils to facilitate heat transfer.
- Control Board: The "brain" of the AC, controlling the various functions of the unit.

This is the most common complaint. Here’s how to troubleshoot: 24 Hour Emergency Air Conditioning Service Near Me Near Ac Service Air Conditioning And Heating Services Near Me
- Check the Power: Ensure the AC unit is plugged in securely and the circuit breaker hasn’t tripped.
- Thermostat Settings: Verify the thermostat is set to the desired temperature and that the mode is set to "Cool."
- Air Filter: A clogged air filter restricts airflow, reducing cooling efficiency. Replace or clean the filter regularly (usually every 1-3 months, depending on usage).
- Blocked Vents: Make sure all vents are open and unobstructed.
- Condenser Coil Issues: The condenser coil, located outside, can become dirty or blocked with debris. Clean the coil gently with a brush or vacuum cleaner. Be careful not to bend the fins.
- Refrigerant Leaks: If the refrigerant level is low, the AC won’t cool effectively. This requires professional attention, as handling refrigerant is hazardous.
- Compressor Failure: A faulty compressor is a serious issue. Symptoms include the AC not cooling, unusual noises, and the compressor not running. This also requires professional repair or replacement.
- Frozen Evaporator Coil: This can happen if there’s poor airflow, a dirty air filter, or low refrigerant. Turn off the AC and let the coil thaw completely before restarting. If it freezes again, there’s an underlying problem.
