• Compressor: The heart of the AC system, the compressor pressurizes the refrigerant, increasing its temperature.
• Condenser Coil: Located outside, this coil releases heat from the refrigerant into the outside air.
• Evaporator Coil: Located inside, this coil absorbs heat from the air inside your home, cooling it down.
• 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 coil.
• Blower Motor: Circulates air through the system, distributing cooled air throughout your home.
• Ductwork: The network of ducts that carries cooled air from the air handler to the vents in your rooms.
• Thermostat: The control center that regulates the temperature and turns the system on and off.

1. The AC Won’t Turn On: Commercial Ac Repair Ac Emergency Repair Near Me 24 7 Air Conditioning Service Heating Repair In My Area

   • Check the Thermostat: Ensure the thermostat is set to "Cool" and that the desired temperature is lower than the current room temperature. Check the batteries in your thermostat.
   • Check the Circuit Breaker: Make sure the circuit breaker for the AC unit has not tripped. Reset the breaker if necessary. If it trips repeatedly, there may be a more serious electrical problem that requires professional attention.
   • Inspect the Disconnect Box: There is usually a disconnect box near the outdoor unit. Make sure the switch is in the "On" position.
   • Check the Outdoor Unit: Make sure the power switch on the outdoor unit is in the "On" position. Check for any obstructions that might be blocking the airflow.
   • Inspect the Condensate Drain: The condensate drain line can get clogged, which can cause the unit to shut down. Look for a drain pipe near the indoor unit. Use a wet/dry vacuum or a wire to clear any blockages.

   • Check the Thermostat: Make sure the thermostat is set to "Cool" and the fan is set to "Auto."
   • Check the Air Filter: A clogged air filter restricts airflow and reduces cooling efficiency. Replace the air filter with a new one.
   • Inspect the Outdoor Unit: Check for obstructions like leaves, grass clippings, or debris blocking the condenser coil. Clean the coil with a soft brush or a special coil cleaner.
   • Check the Indoor Unit: Make sure the blower motor is running. If the blower motor is not running, check the capacitor (see below) or the motor itself.
   • Refrigerant Leak: If the refrigerant level is low, the AC will not cool properly. This requires professional attention as it is illegal to handle refrigerants without the proper certifications.

   • Check the Air Filter: A dirty air filter restricts airflow and reduces cooling capacity. Replace it with a new one.
   • Check the Condenser Coil: Make sure the condenser coil is clean and free of debris.
   • Check the Evaporator Coil: A dirty evaporator coil can also reduce cooling efficiency. This is often more difficult to access and may require professional cleaning.
   • Check for Blocked Vents: Make sure all vents are open and unobstructed.
   • Check Ductwork for Leaks: Leaks in the ductwork can cause cooled air to escape, reducing cooling efficiency. Seal any leaks with duct tape or mastic sealant.
   • Refrigerant Leak: A low refrigerant level will reduce cooling capacity. This requires professional attention.

   • Squealing or Screeching: This could indicate a problem with the blower motor, a worn belt, or a problem with the compressor. Turn off the unit and call a technician.
   • Clicking: Clicking can be normal as the unit cycles on and off. However, if the clicking is excessive or accompanied by other problems, it could indicate a problem with the capacitor or the compressor.
   • Hissing or Bubbling: This could indicate a refrigerant leak. Turn off the unit and call a technician.
   • Grinding: This could indicate a problem with the compressor or the blower motor. Turn off the unit and call a technician.

   • Clogged Condensate Drain: The most common cause of water leaks is a clogged condensate drain line. Clear the blockage with a wet/dry vacuum or a wire.
   • Frozen Evaporator Coil: If the evaporator coil freezes over, it can melt and cause water to leak. This is often caused by restricted airflow (dirty air filter) or low refrigerant. Turn off the unit and let it thaw. Check the air filter and have a technician check the refrigerant level.
   • Cracked Drain Pan: The drain pan can crack or become damaged over time. If you see water leaking from the drain pan, it may need to be replaced.

• Replacing the Air Filter: This is the easiest and most important maintenance task. Replace the air filter every 1-3 months, depending on the type of filter and the environment.
• Cleaning the Condenser Coil: This can improve cooling efficiency. Turn off the power to the unit, remove any debris from around the coil, and gently clean it with a soft brush or a coil cleaner.
• Clearing the Condensate Drain Line: Use a wet/dry vacuum or a wire to clear any blockages in the drain line.
• Replacing a Capacitor: The capacitor provides the starting power for the compressor and the blower motor. If the unit won’t start or runs intermittently, the capacitor may be faulty. This requires some electrical knowledge and care. Turn off the power, locate the capacitor (usually a small cylinder), and test it with a multimeter. If it’s faulty, replace it with a capacitor of the same rating.
