Air conditioning companies are important no matter where you live. If your HVAC system, unfortunately, goes out, staying in your home can become pretty harsh. Repairing your unit can cost a lot of money, which is why it is so important to ensure your air conditioning unit is always in the best condition it can be. Whether you use air conditioning companies to do your upkeep or you do it yourself, here are the most common air conditioning problems to be aware of. 


Most common air conditioning problems 

1. Filter 

This is usually a simple one. A common problem that causes air conditioners to stop working is a dirty or clogged filter. Use air conditioning companies or use suggestions provided by the manufacturer, whether through manual or online, to fix the problem. If this problem has not yet occurred and you are just looking to prevent it, follow your manufacturer’s instructions on how often to change the filter. These times typically vary from one to three months. For cleanable filters, check to make sure light can pass through the filter. If not, it is due for a cleaning. 

2. The Thermostat 

This may seem obvious but it is often a problem that is overlooked. Make sure your thermostat is turned on. It would also be wise to make sure it is clean on the inside, level, and not in direct sunlight. If problems continue, it may be another issue, or you may need to contact one of your local air conditioning companies to take a look. 

3. Leaking Refrigerant

If you notice coolant beginning to leak from your unit, it may start to break down and perform incorrectly. The cost of repairing refrigerant leaks depends on the location of the leak. A best practice is to choose one of our local air conditioning companies to check this annually.  

4. Drainage 

The drain line is an important part of your HVAC unit. It can become clogged and fill the drain pan. If the drain pan becomes too full, water will begin to leak from your unity and cause significant damage to your unit and the wiring surrounding it. 

5.The Breaker 

Breakers and fuses have one particular function and that is to protect your home from electrical fluctuations. When it comes to your HVAC unit, they protect your unit’s motor that powers the fans. If any of these components stop functioning the unit will begin to slowly lose efficiency before burning out entirely. 

6. Capacitors 

A capacitor is a device in your unit that keeps the motors inside the system powering the compressors and fans. They work by directing electricity to the motor, to start it and to keep it running. A failing capacitor will shut down the motor and prevent the AC from working. 

7. Compressor

Compressors compile energy and apply it to the refrigerant to propel it through the coils of the system. This is done to create the exchange of heat necessary to fluctuate the temperature. A failing compressor will prevent your HVAC system from cooling your home. This can also be due to their compressor not having enough refrigerant. Lack of refrigerant will cause the compressor to overheat and seize. Don’t use too much refrigerant, however, as this can flow back into the compressor and cause it to stop functioning. 

8. Evaporator Coils 

These coils are used to absorb the heat in the air and cool it down so that it can be sent through the air ducts and reach different parts of the home. However, these coils can become corroded, so it is important to maintain and fix them when necessary. This usually needs to be done around every three years. 

9. Condenser Coils 

These coils are located outside, around the condenser. This makes them prone to becoming dirty. They are usually relatively simple to clean, usually with a hose. This should be done about once per year. If your condenser coils are too dirty to clean yourself, you can request a chemical clean from any local air conditioning company. 

10. Worn Contactor 

Every compressor, condenser fan motor, and blower motor in an AC unit will have contactors. These devices are what make the electrical connection possible that activates the motors and compressor. If these become damaged, arced, or if there is pitting, the electrical current will become weaker and may cause your unit to shut off.
