Most common Air Conditioning Problems

Finding out something about your air conditioning problem before your Third generation HVAC technician arrives to your home can help you save some time and money. Common issues include the compressor failing to turn on, the air not coming out cool enough, low airflow and water leaks. Here are the top problems that may cause your air conditioning system to break down.

Fuse Box.

The first thing you should do if your air conditioner is performing poorly is to check the fuse box or circuit breaker that services the unit. The fuse may have to be replaced or the circuit breaker reset. Also, if the air conditioner turns on and off frequently, the compressor and fan controls may be deteriorated.


The filters may also need to be changed. Clogged, dirty filters stop normal airflow and decrease a system’s efficiency considerably.

Water Leaks.

Leaks are generally associated with low refrigerant or a blocked drain pipe. Blockages could be fixed by clearing out the clogged pipe inside the evaporator coil pan.


An icy coil typically suggests an issue with the airflow, which include restrictions caused by grimy air filters or blocked return air ductwork. Frozen coil could be just one of several problems including dirty filter, low air flow, low on freon, or some other causes. Low air flow– Have the coils been cleaned lately? You may also need to clean off the evaporator or condenser coils by brushing them off or vacuuming them.

Low Refrigerant.

Refrigerant (more typically referred to as Freon) is the chemical that cools the air. Low refrigerant may indicate a leak or problem with the refrigerant system. If your system needs to be recharged with refrigerant, usually that means there is a leak. If your unit is turning on, but the air isn’t cooling efficiently, your refrigerant may be low.

Faulty Wiring.

Bad wiring commonly stops the system from getting power, or can trip the circuit breaker. With Faulty installation, even the best energy-efficient unit sacrifices its efficiency when installed incorrectly.

Circulating Air That Does Not Get Cooled.

When you can feel that air coming via the vent is equally as warm as the air outside-there are a couple of possible explanations. Refrigerant may be low. The fuse may need replacing. In an older unit, the fuse and controls may be deteriorated. The majority of air conditioning problems are a result of flawed installation, poor service, and not enough maintenance. Bad wiring, low refrigerant and airflow problems can be detected in the course of routine maintenance tune-ups. In many cases, the only way you can prevent these common problems is by participating in a preventive maintenance program offered by Third Generation Heating and Air Conditioning.
