HVAC Unit During AC Repair in San Antonio, TX

AC systems are essential equipment for maintaining a comfortable and habitable environment, particularly during the sweltering summer months. However, just like any other mechanical system, your AC unit can experience emergencies that disrupt its operation and compromise its efficiency. Recognizing and addressing these emergencies promptly is crucial to ensure the AC system’s smooth functioning and prevent further damage or discomfort. The following are some common AC emergencies.

Refrigerant Leak

Refrigerant is crucial to an air conditioning unit’s operation as it facilitates the heat transfer that cools your home. However, a leaking refrigerant is a severe issue. Beyond affecting your AC’s efficiency, it poses risks to the environment and possibly your health. Symptoms of a refrigerant leak typically include decreased cooling effectiveness, longer system run times, or ice buildup on the outdoor unit. Your AC may even emit a strange hissing noise.

Solution to a Refrigerant Leak

The solution to a refrigerant leak is typically a two-step process handled by a professional. First, the technician will diagnose the system using specialized tools to detect the leak source. They then repair the leak, typically by soldering, followed by recharging the system with the appropriate type of refrigerant. Regular AC maintenance can prevent such emergencies, ensuring your system is always working at its peak efficiency.

Faulty Capacitors

Capacitors act as temporary power sources, smoothing voltage fluctuations and aiding in the proper functioning of circuits. One way to identify a faulty capacitor is through physical inspection. Look for signs of bulging, leaking, or cracked casings as these indicate internal damage. A defective capacitor may also cause devices to malfunction, produce strange noises, or exhibit erratic behavior.


It is crucial to seek professional help when faced with a faulty capacitor emergency. An experienced technician or electrician should be contacted to diagnose and resolve the issue. They will start by safely disconnecting the power source to prevent any electrical hazards. Next, they will carefully examine the faulty capacitor, testing it with specialized equipment to determine the extent of the damage.

Based on the assessment, the professional will replace the faulty capacitor with a new one, ensuring it matches the required specifications and voltage ratings. They will adhere to safety protocols and industry standards throughout the process. Finally, the repaired device will undergo thorough testing to ensure its proper functioning and prevent any future emergencies related to faulty capacitors.

Leaking Ducts

Ducts play a crucial role in HVAC systems, distributing heated or cooled air throughout a building, ensuring comfort, and maintaining air quality. However, when these ducts develop leaks, a range of problems arise. Detecting leaking air ducts can be challenging, but signs may include uneven airflow, rooms that are difficult to heat or cool, excessive dust accumulation, or hissing sounds near the ductwork. Additionally, high energy bills can indicate inefficient ductwork due to air loss.


Addressing leaking ducts requires professional intervention. A qualified HVAC technician will begin by conducting a thorough inspection to locate the leaks. This may involve using tools like smoke pencils or thermal imaging cameras to identify areas of air leakage. Once the leaks are identified, the technician will seal them using specialized materials such as mastic sealant, metal tape, or aerosol sealant. Larger or more complex leaks may require the replacement of damaged sections of ductwork.

Clogged Air Filters

Air filters play a crucial role in maintaining air quality and HVAC system efficiency. These filters are specifically engineered to trap dust, pet dander, pollen, and various other airborne particles. As a result, they effectively prevent the circulation of these contaminants within the system and hinder their entry into indoor environments.

One way to tell if air filters are clogged is by reduced airflow. If you notice weak airflow from vents or difficulty in maintaining a comfortable temperature, the culprit may be a clogged air filter. Another sign is an increase in energy consumption as the HVAC system has to work harder to compensate for the reduced airflow. Additionally, a visual inspection of the air filter can reveal a buildup of dirt and debris.


To address a clogged air filter emergency, the technician will start by turning off the HVAC system to prevent further damage. They will then carefully remove the clogged air filter and replace it with a clean one of the appropriate size and rating. After installation, they will clean any accumulated debris from the surrounding area. Finally, the technician will inspect the system for any potential damage or issues caused by the clogged air filter, ensuring optimal performance.

Water Leaks

AC water leaks can pose a significant emergency due to the potential damage they can cause to the surrounding structure and electrical components. The main cause of an AC water leak is typically a clogged condensate drain line. Over time, dirt, dust, and debris can accumulate in the drain line, obstructing the flow of condensation out of the unit. This results in water backing up and eventually leaking from the AC system.


To resolve the issue, it is crucial to seek professional assistance. An HVAC technician will start by inspecting the condensate drain line for clogs. They will use specialized tools, such as a wet/dry vacuum or a flexible brush, to remove any debris obstructing the drain. In severe cases, they may opt to flush the line with a solution or compressed air to clear the blockage thoroughly.

Additionally, the technician will examine the condensate pan for cracks or damage as these can also contribute to water leaks. If necessary, they will repair or replace the pan to prevent future leaks. Once the drain line is clear and the pan is secure, the technician will ensure proper AC system operation and check for any other potential issues.

Faulty Thermostat

A thermostat acts as a control center, monitoring the ambient temperature and signaling the AC unit to either cool or heat the environment accordingly. The most common cause of a faulty thermostat is a malfunctioning temperature sensor, which can result from wear and tear, electrical issues, or improper calibration. When a thermostat fails to measure the ambient temperature accurately, it can miscommunicate with the air conditioner, leading to erratic cooling cycles, inconsistent temperatures, or even a complete shutdown. The consequences of a faulty thermostat can be troublesome.

In hot weather, the AC may fail to turn on, leaving occupants sweltering in uncomfortable heat. Alternatively, the system might run continuously, overcooling the space and wasting energy, resulting in skyrocketing utility bills. Additionally, a malfunctioning thermostat can cause undue strain on the AC unit, potentially leading to compressor damage or a complete breakdown.


The professional technician will thoroughly examine the faulty thermostat, checking for loose connections, faulty wiring, or any signs of physical damage. They will also test the temperature sensor’s accuracy and re-calibrate the thermostat if necessary. If the thermostat is beyond repair, the technician will replace it with a new one, ensuring compatibility with the cooling system. Finally, they will verify the correct functioning of the newly installed thermostat and ensure it communicates accurately with the AC unit.
