Common AC Problems And Solutions

With the warmer weather approaching, you must ensure your air conditioner is running correctly. ACs require regular maintenance and tune-ups, to ensure this is done correctly, it is recommended that you hire a professional. AC repairs can be costly, and taking preventative measures can help you avoid massive repairs. Below are some common AC problems and their solutions. 

Air Conditioner Is Not Turning On 

If your air conditioner is not turning on, check your thermostat batteries and replace them if they are dead. If the batteries are in good condition, you can check the settings of the thermostat to determine if the cooling mode is turned on to match your desired temperature. Check your circuit breaker if the thermostat is on, but the AC is not turning on. Your AC will not turn on if the circuit breaker is tripped; you can fix this by resetting the circuit breaker: by flipping the switch on and off. 

Cold Air Is Not Blowing From The Air Conditioner

The air filter inside your air conditioner can get very dirty and prevent cold air from coming out. This can further freeze up the condenser unit, which will limit how much cold air your AC can produce. Switching out the air filter each month is the solution to ensuring cool air can flow into your home. 

The Air Conditioner Is Freezing The Outside Unit

There are a few possible reasons your AC could be freezing up. One of the reasons could be insufficient airflow; ensure you check your filter to confirm that it is clean. Low outside temperatures can also cause your AC to freeze. The air conditioner can also have low coolant levels or blower porter problems. These problems can all cause your air conditioner to freeze, preventing you from cooling your home. 

Air Conditioning Refrigerant Leak 

The temperature will vary when the coolant in your AC is leaking. This will prevent the unit from performing correctly; these leaks can result in low efficiency, coil freezing, high power consumption, uneven cooling, or a damaged compressor. You can easily avoid these problems with regular maintenance; check your AC regularly for these leaks. 

Noise Coming From The Air Conditioner

Many different problems can cause the air conditioner to make noise. If your AC has a refrigerant leak, the sound produced may sound like hissing. A relay problem occurs when your AC makes a clicking noise when turned on and off. If there is an issue with the blower, that could result in a thumping, rattling, or banging sound. The fan motor or compressor produces a screeching noise if there are faulty electric components, you will hear a buzzing sound. 

Frozen Evaporator Coil 

When your AC is not receiving sufficient airflow, the evaporator coil can freeze. This frozen coil can cause your AC to freeze up and stop working. Insufficient airflow can be caused by blocked ducts and vents, a faulty fan, or dirty filters. Clean filters are essential to maximizing indoor air quality and airflow. 

Electric Control Failure 

The fan controls and compressor can wear out as you frequently turn the AC on and off. The compressor, the blower motor, and the fan motor all make an electrical connection that starts the unit. If there is a connection problem, the motor, and compressor will be prevented from turning on. 

Water Leaking Outside From The Air Conditioner

It is usual for water to leak outside the AC unit on a humid or hot day. During colder months, it is also normal for water to leak, the unit can freeze in these cooler temperatures, and the water will leak when it melts. 

Sensor Problem 

Near the evaporator coil, the Ac has a thermostat. This measures the temperature of the air inside the evaporating coil and will adjust the cooling to fit the room’s condition. When this sensor gets out of position, the AC can start randomly turning on and off. You can fix this problem by adjusting the sensor placement; it should always be near the evaporator coil but never touching it. There are wires that hold the sensor in position; these can easily bend to properly place and hold up the sensor. 

Drainage Problem 

Drain pipelines can become clogged with algae, dirt, and dust, preventing the water from draining correctly. If the water is not draining, mold, mildew, or fungus can grow, and foul odors or gasses can filter into your home. You can prevent this with regular maintenance, ensure you inspect and clean the drain line to avoid this issue. 

Many issues can occur with an air conditioner. Most problems have an easy solution, but regular AC maintenance is essential to avoid future problems that may be costly.
