Common Causes of Air Conditioning System Failure

The summer heat stops for no one, so you need your air conditioner running its best to combat those exhaustive temperatures. Even in the Northeast, the heat and humidity can skyrocket and make anyone avoid spending a day outside. When your air conditioner is out of order, it can spell disaster for your cooling efforts. Though you can tweak and repair some problems on your own, other problems require professional assistance.

5 Common Air Conditioning Problems

1. Frozen Coils

If your air conditioner continues to run but only blows out warm air, ice may have coated the evaporator coils. Ice buildup can happen for reasons such as debris buildup, low refrigerant or a blocked drain. Turning off the thermostat or switching it to the fan setting for a few hours will thaw the ice. If something is blocking the coils, you’ll need a professional to handle the repairs.

2. Leaks and Low Refrigerant

When a leak develops in your air conditioning lines, it causes the refrigerant to run low, reducing the cooling in your home. Unfortunately, you can’t just replace the missing refrigerant. A technician needs to locate and repair the leak, refill the refrigerant and test the lines to ensure everything is in working order.

3. Sensor Connection

A misaligned sensor in the thermostat is one of many common air conditioner problems. This misalignment happens when the sensor is knocked out of position and touches the coil. You can fix the problem by carefully bending the wire that holds the sensor in place, making sure to keep it close to the coil without touching it.

4. Fan Malfunction

Air conditioning units have fans that blow air over the evaporator coil and the condenser. Fans often malfunction due to faulty motors, worn belts and debris buildup. Setting up a maintenance plan with a professional can catch fan problems ahead of time before they lead to compressor failure.

5. Poor Drainage

Your air conditioner removes moisture from the air and sends it out the drain line. A clogged drain line means trouble for your system as it results in leaks and potential water damage, including mold growth. A routine maintenance check will find leaks and blockages and prevent water damage in your home.
