During the summer, air conditioning problems are a constant concern for homeowners. You need efficient AC, and you need it to be working all year round.

If your AC unit has stopped working, you want to fix it quickly. The longer a mechanical issue is left without attention, the more expensive it will be to sort out. However, you can reduce the costs by diagnosing the problem yourself.

There are specific issues that are common to all air conditioning units. Identifying the problem early can save you money.

Do you need help with the state of your air conditioning system? Then, keep reading to learn about common AC problems you should know.

1. Not Turning On 

One of the most common air conditioning issues is not turning on. It could be due to a power failure, incorrect thermostat settings, or a blown fuse.

If this is the case, check the breakers to ensure all fuses are in the correct position. Then, check the thermostat settings to ensure it is set to the right temperature and power settings.

If everything appears in order, you may need to inspect the motor. Check its wiring to ensure all connections are in place. If there is a loose connection, you must fix it.

If none of these solutions help, then it may be necessary to replace the entire unit. If this is the case, find ac installation here to ensure your new air conditioner is installed properly.

2. Freezing up Outside Unit

One common issue that can happen with an outside air conditioning unit is that it can freeze up. This can be caused by a variety of different factors, from a clogged air filter to incorrectly set thermostat levels to outdoor temperatures that are too cold for the system. If the unit has frozen up, then it will no longer be able to circulate cool air into the home.

If you suspect your outside unit is freezing, you should immediately turn off its power to prevent any more problems. Replace the air filter, have a professional inspection, check the refrigerant levels, and ensure that the return and supply trunks are not blocked up due to debris.

You can also try cleaning the coils. Check the fan to ensure it functions correctly.

3. Unusual Noises 

Unusual noises emanating from an air conditioning unit indicate something is not quite right and should be addressed. Common noises include loud pulsing, thumping, or even rattling.

If these sounds persist and become louder, it is likely that a major air conditioning problem is developing and may even cause a breakdown. In some cases, such unusual noises are caused by debris or other objects stuck in the fan blades or other components.

However, it is best to have the unit professionally inspected to determine the source of the problem. Seek the appropriate repair. Otherwise, the efficiency and performance of the air conditioner could be compromised, and the unit may need to be replaced.

It pays to be vigilant. Listen out for any unusual noises from the air conditioning unit and take the necessary steps to fix the issue.

4. Refrigerant or Water Leak 

Another issue to look out for is a refrigerant or water leak. Refrigerant is a chemical compound used in air conditioning systems to transfer heat from inside a building to the outside. If this chemical isn’t kept at the specified level in the home HVAC, it can cause problems.

If you notice an ongoing decrease in your air conditioner’s performance, it could mean a refrigerant leak in the system. Minor refrigerant leaks are more accessible and affordable to fix, while major leaks can be expensive and difficult to repair.

A professional can inspect your air conditioner to detect a potential refrigerant leak. A technician will check the system for any visible signs of leakage and abnormally low pressure. If the pressure is low, the technician will start searching for the source of the leak and can fix the problem before it gets worse.

Other problems to look out for include refrigerant lines that are corroded or bent and faulty capacitors that may need to be replaced. If any of these problems are present, contact a qualified technician as soon as possible. This will ensure your air conditioner is running efficiently and safely.

5. Blowing Warm or Hot Air 

Blowing warm or hot air is one of the most common air conditioning problems to look out for. Generally, this will occur when the thermostat has been set to a lower temperature than the current room temperature and the air filters are clogged. It should be addressed immediately to ensure it is manageable.

Begin by checking the fan, as a dirty fan can often fail to blow proper air and even lack the power to cool the air. If the fan appears clean, check the ducts to ensure they are not blocked, as this can impede air flow and reduce the system’s efficiency.

If the fan and ducts appear clean, you may need to check the unit for refrigerant leakage, as this will prevent it from cooling or heating the air. Repairing these common air conditioning issues can keep your system in peak condition and make sure your home remains comfortable.

6. Repeated Tripping Circuit Breakers 

Repeated tripping of a circuit breaker can indicate an air conditioning issue. It usually occurs when a circuit is overloaded due to a faulty appliance or power surge. It can also be caused by a malfunctioning fan motor, compressor, or capacitor, which could overload the circuit.

The best way to prevent a circuit from tripping is to inspect your air conditioning system regularly to ensure all its components are in good working order. If it is a faulty appliance, replace it or have it repaired. Using reliable surge protection appliances or installing a whole-house surge protector can prevent power surges.

Look Out for These Common Air Conditioning Problems

No matter how new or old your air conditioning units are, regular maintenance and inspection are essential to ensure they’re running efficiently. Make sure to watch for common air conditioning problems so you can troubleshoot them quickly.

Don’t delay! If you have any air conditioning issues, contact a local technician for professional care today!
