Unfortunately, air conditioners aren’t immune from occasionally experiencing issues. Some AC trouble might require simple repairs, while others require a complete system replacement.
Being aware of the most common air conditioner problems can ensure you have your system replaced before it completely breaks down and leaves your home without cold air.
In the latest blog post from Rusk Heating and Cooling, we’ll discuss some of the most common AC issues and provide insights on when it’s time to consider a replacement. Contact our team today to learn more or to schedule AC services in the Greater Cincinnati Area.
Refrigerant leaks can significantly impact the performance of your air conditioning system. An air conditioner’s refrigerant is responsible for reducing your air supply’s temperature, helping it cool your home.
When there is a leak, the refrigerant will gradually escape. This will lead to reduced cooling capacity, longer cooling cycles, and increased energy consumption. If you notice that your AC is struggling to maintain a comfortable temperature or there are hissing sounds coming from the AC unit while it’s running, it could indicate a refrigerant leak.
A professional technician can locate and repair the leak, and then recharge the air conditioning unit with the appropriate amount of refrigerant.
Reduced AC system inefficiency can be due to a variety of factors, including dirty filters, worn internal parts, or the system’s age. You’ll likely notice a drop in system efficiency in the form of higher energy bills, longer cooling times, or inadequate cooling.
Regular maintenance, including cleaning coils, lubricating moving parts, and ensuring proper airflow, can help improve system efficiency. However, if the system is old or severely worn, you’ll see long-term benefits in replacing it with a newer, more energy-efficient model.
Clogged Air Filters
When an AC system’s air filter becomes clogged, it can affect the system’s performance and overall efficiency. With usage, it’s common for dust, dirt, and debris to build up in the air filter, leading to restricted system airflow and making the system work harder to cool your home.
To avoid cooling issues, air filters should be replaced every 1-3 months, or as recommended by the manufacturer. This will help the system maintain optimal airflow, improve indoor air quality, and ensure efficient cooling.
Frozen Evaporator Coil
Frozen evaporator coils most often occur when there is restricted airflow. Restricted airflow is usually caused by dirty air filters, blocked vents, or closed dampers, which prevent sufficient warm air from reaching the evaporator coil.
As a result, the coil becomes excessively cold, causing condensation to freeze on its surface. This can lead to reduced cooling capacity and even a complete system shutdown. If you notice ice formation on the evaporator coil or reduced airflow from the vents, it’s important to address the issue promptly.
Cleaning the dirty air filter, clearing any blockages, and ensuring proper airflow can help resolve this problem.
Your thermostat is the point of communication between yourself and your HVAC system. A faulty thermostat can inaccurately read temperatures or not communicate properly with your air conditioning system.
Faulty thermostats can result in temperature inconsistencies, short cycling, or prevent the air conditioner from turning off. A malfunctioning thermostat may be due to wiring issues, a sensor problem, or a need for recalibration.
In some cases, a simple repair or recalibration may solve the problem. However, if the thermostat is outdated or the underlying issues are beyond repair, replacing it with a new thermostat can provide more precise temperature control and enhance the overall efficiency of your cooling system.
Your air conditioner’s capacitors help start the unit’s compressor and fan motors. If the capacitors malfunction, you may experience difficulties with your AC starting up, experience intermittent cooling, or even complete system failure.
Signs of faulty capacitors include loud humming sounds, the AC not turning on, or very poor airflow. Sometimes, a professional technician can diagnose and replace faulty capacitors, ensuring that your AC functions properly. Other times, your system may need to be replaced to ensure it operates properly.
Prompt repair or replacement of capacitors can prevent further damage to the system and restore efficient cooling.
