10 Most Common AC Problems and Their Solutions

Air conditioning is essential in Fairfax, and life can be pretty unbearable if the air conditioner goes out. AC repairs can be costly, so it is necessary to schedule regular tune-ups and maintenance with a professional and experienced AC contractor to enjoy its performance. When summer season comes along, you want your AC to run without a hitch. However, even the best AC can run into issues over time. It can destroy your summer breaks and gatherings that take place in your home.

It is essential that your AC is maintained professionally. From cleaning to changing the air filter, and various inspections are included in the maintenance. If your AC is not maintained, it can cause a lot of problems. It is essential to learn about the common AC problems so that you can easily take preventive measures to avoid costly repairs. Here in this post, you will know the most common AC problems and their possible solutions.

1.      Air Conditioner Won’t Turn On.

It is one of the most common AC problems faced by my people. If your air conditioner is not turning on, make sure to check the thermostat batteries. Replace the thermostat batteries if they are dead. If there is no issue with the batteries, check the thermostat settings to learn whether the cooling mode is in the desired settings. However, if there is no issue with the thermostat setting, check the circuit breaker. In the case of a tripped circuit breaker, AC will not turn on. Make sure to reset the breaker by flipping the switch off and on.

2.      AC Leaking Water Outside

Water leaking outside from your air conditioner on a humid or hot day is considered normal. It is also expected when the water leakage occurs outside cold weather, as the unit can freeze up and leak when melt. The following are some more reasons for water leakage:

• Improper installation
• Dirty air filter
• Blocked drain pipe
• Broken condensate pan
• Low coolant levels

Make sure to clean drain pipes, and pump system with a bleach solution. You should check the electrical connection. If you cannot fix this issue, hire experts from one of the best AC companies in Fairfax.

3.      Air Conditioner Refrigerant Leak

Temperature can vary if the coolant in the AC starts leaking. It will eventually affect the performance of the unit. A refrigerant leak can result in:

• High power consumption
• Low efficiency
• Damaged compressor
• Coil freezing
• Uneven cooling

Make sure to check the refrigerant level. Also, change the filter monthly and inspect the condensate drain weekly to maintain and prevent the refrigerant leakage.

4.      AC Not Blowing Cold Air

Your air conditioner will not blow cold air due to a dirty air filter. It can block the unit’s airflow, and it can further freeze up the condenser unit and limit the cooling power of your air conditioner. However, a broken duct can also be the reason if the AC is blowing warm air. To solve this issue, make sure that the outside unit is running properly. Moreover, make sure to change the air filter every month. It will help to blow cold air.

5.      The Compressor Is Not Running

If your compressor is not running, it is probably due to a burned wire, defective start capacitor, or a defective compressor. To solve this issue, make sure to adjust the refrigerant charge, check the capacitor. However, you can clean the condenser coil for better functioning of a compressor. You can also replace the compressor if it does not reset.

6.      AC Making Noises

It is one of the most common AC problems experienced by the majority of people. Your air conditioner can make various sounds depending on the type of the problem. Here are the reasons which can lead to the production of AC sounds:

• A leaky refrigerant can produce a hissing sound
• Rattling, thumping, or banging noises mean there is an issue with a blower or motor assembly.
• The fan motor or compressor
•  produces a screeching noise.
• Faulty electrical components could produce the buzzing sound.
•  
• A clicking sound, while turning on or off your air conditioner, might be a relay problem.

7.      Frozen Evaporator Coil

When the air conditioners do not receive sufficient air needed, it can freeze the evaporator coil. A frozen evaporator coil can result in freezing up your AC and eventually stop working. Blocked ducts and vents, a faulty fan, or dirty filters can cause insufficient airflow. However, you can solve this problem by cleaning the air filter. It is because the air filter maximizes airflow and indoor air quality.

8.      Electric Control Failure

With frequent turning on and off the air conditioner, the compressor and fan controls can wear out. The compressor, condenser fan motor, and the blower motor make an electrical connection to start the AC unit. Besides, the connection issue can prevent the compressor and motor from turning on. Make sure to check all the electrical connections to determine the issue and stop it. However, living in Fairfax, you can hire professionals to get rid of the problem.

9.      Sensor Problem

A thermostat sensor is located near the evaporator coil. It measures the air temperature in the evaporating coil and adjusts it based on your room’s condition. If the sensor is not working, your air conditioner can randomly turn off and on and cycle frequently. Make sure to place the sensor near the evaporator coil without touching each other. You can bend the wire that holds the sensor in its right position.

10. Drainage Problem

The drain pipes of the AC can be clogged with algae, dust, and dirt. It is also one of the most common AC problems. Mold, fungus, and mildew can be developed with improper water drainage in the air conditioner. Besides, foul odor or gas can filter in your home due to this. To prevent this issue, make sure your drain pipeline is regularly cleaned, maintained, and inspected. Moreover, the AC, which is not mounted level, may not drain properly. Make sure to hire experts and get your air conditioners inspected and serviced regularly.
