Common AC System Problems

Keeping your home or office cool during the hot summer months, or all year-round in certain climates, is often a necessity. When the air conditioning isn’t working it can make things very difficult. It also often occurs at the most inopportune times. The air conditioning issue you have can depend on the type of air conditioner, central air conditioning or a room air conditioner. Regular maintenance can help you avoid many of the common AC system problems so it’s important to have a technician that you know and trust to help solve any problems.

Common AC System Problems

Air conditioning systems are not just a luxury as they are often necessary in extreme temperatures. Regular maintenance can ensure your air conditioning lasts and works just when you need it to. However, there are issues that can occur so consider the following common AC system problems.


Refrigerant leaks are common and can impact your air conditioning system. If your air conditioner is low on refrigerant, it can be due to a leak or it was undercharged when it was installed. Adding refrigerant will not solve the problem if your air conditioner is leaking as you’ll need a professional. A trained technician can address the issue, test the repair, and then charge the air conditioning system with the right amount of refrigerant. The manufacturer specifications for the refrigerant charge is optimal when it comes to your air conditioner’s performance and efficiency. Due to the harmful effects a refrigerant leak can have on the environment, it’s important to promptly address the issue.

Poor Maintenance:

Regular maintenance can ensure that your air conditioner stays in good working condition. However, poor maintenance can lead to issues including compressor and fan failure which can ultimately lead to premature failure. It’s important to maintain the air conditioning coils and filters to ensure the longevity of your air conditioning system.

Sensor Issues:

A common issue with air conditioners involves the sensors. Air conditioners have a thermostat sensor behind the control panel that measures the temperature of incoming air in the evaporator coil. One of the common issues with sensors is when they are knocked out of position. This can cause the air conditioner to cycle constantly or operate erratically. When it comes to the air conditioning sensor, it should be near the coil but not directly touching it. You can adjust the position by bending the wire that holds it in place. This takes a lot of care and caution so you may want to have a professional electrician in Pico Rivera diagnose and address the issue.

Electric Control Failure:

If you turn the air conditioner on and off frequently, the compressor and fan controls can wear out. This is quite common with large, oversized air conditioning systems. Regular maintenance can help address this issue as electrical connections and contacts are checked. This is done because corrosion of wire and terminals is a common air conditioning issue.

Drainage Issues:

Drainage issues are a common problem with air conditioners. This can be due to an issue with how it is mounted as it needs to be level to drain properly. Additionally, if it’s humid outside, condensation can cause clogs. Be sure and check the condensate drain to make sure it’s draining properly.
