Understanding the Most Common Air Conditioning Repair Issues

As a business owner at Advanced Cooling, servicing Texas and Oklahoma since 2001, our team understands the critical role that air conditioning plays in maintaining comfort and productivity in both residential and commercial environments. Over the years, we have encountered and resolved various air conditioning issues. Below, we delve into the most common air conditioning repair problems, helping you better understand what might cause your system to underperform and what steps can be taken to rectify these issues.

Refrigerant Leaks

One of the most prevalent issues we encounter is refrigerant leaks. An AC unit’s refrigerant is critical for cooling air; the system’s cooling capacity is greatly diminished if it leaks. Low refrigerant levels usually indicate a leak, which can be due to various reasons, including corrosion or physical damage. Identifying and repairing leaks is essential to ensure the system operates efficiently. In some cases, simply refilling the refrigerant will not permanently fix the issue; tracing and repairing the leak is necessary for sustainable performance.

Frozen Evaporator Coils

Evaporator coils absorb heat from the air, but this exchange process is interrupted if they become frozen. Frozen coils can result from various factors, including inadequate airflow due to dirty filters or blocked ducts, low refrigerant levels, or other mechanical problems restricting refrigerant flow. Regular maintenance checks can help prevent coil freezing. If you notice ice buildup on your unit, especially during warm weather, it’s time to call in the professionals to diagnose and remedy the situation.

Dirty Condenser Coils

The condenser coils in the outdoor unit expel heat extracted from the indoor environment. However, exposure to the outdoor environment can make these coils dirty over time. Dust, dirt, and debris can impede the coils’ release of heat, forcing the system to work harder and potentially leading to overheating. Regular cleaning and maintenance by professionals can prevent this issue and help ensure efficient operation.

Sensor Problems

Air conditioning units rely on sensors to measure and regulate room temperature. These sensors are usually placed behind the control panel but can sometimes be knocked out of position or become faulty. A troubled sensor might result in erratic behavior, such as cycles starting and stopping irregularly. Professional technicians can adjust or replace these sensors to restore proper functionality.

Electrical Control Issues

Frequent cycling—where your air conditioning system turns on and off excessively—could stem from issues with the electrical controls. Relays and control switches within the unit can become corroded or worn out, especially in oversized systems for the cooling load. This not only strains the system but also reduces its lifespan. Regular electrical inspections can catch these issues early, ensuring smooth operation.

Drainage Issues

Humidity control is another vital function of air conditioning. Units typically have a drainage system for the moisture they remove from the air. However, if the drain system becomes clogged or the drain pan fills up, it can lead to water leakage and damage. In more humid environments like Texas and Oklahoma, ensuring the drainage system is clear of obstructions is especially important during maintenance checks.

Thermostat Malfunctions

The thermostat is the control center of your cooling system, and if it malfunctions, the entire system can suffer. A faulty thermostat can lead to inaccurate temperature regulation, causing discomfort and inefficiency, whether due to a miscalibration or a technical failure. Regular calibration and occasional replacement of old thermostats can ward off these issues.
