A well-maintained air conditioning system can boost your home’s resale value and reduce energy costs. It can also protect against health problems like heat exhaustion and heat stroke.
However, some issues may require professional help. In such cases, it is best to call in Round Rock AC Repair. Here are some common AC problems that may need a fix: Refrigerant leaks, electrical problems, or foul smells.
Unexpected AC shutdowns can be a sign of many different issues. Some problems are minor and can be fixed by a homeowner, while others are more severe and may require professional help. A professional technician can determine the exact cause of an unexpected AC shutdown and recommend the best solution.
Unplanned AC shutdowns can be caused by a number of factors, including overheating and clogged air filters. A clogged air filter restricts airflow, leading to overheating and forcing the system to shut off as a safety measure. Changing or cleaning the air filter regularly can resolve this issue and prevent it from occurring in the future.
Other common causes of unexpected AC shutdowns include thermostat problems, clogged refrigerant lines, and dirty compressor coils. Inspecting the thermostat wiring and ensuring that it is properly set can help to avoid unnecessary AC shutdowns. Additionally, replacing the batteries in the thermostat can help to ensure that it is properly functioning.
Unexpected AC shutdowns can also be caused by a faulty evaporator coil switch. If the switch is not properly positioned to collect overflowing water, it can prevent the system from operating and lead to an unexpected shutdown. Inspecting the coil for visible signs of moisture or mud and cleaning them as needed can resolve this problem. Additionally, ensuring that all vents are open and not obstructed can also improve airflow and reduce the likelihood of an unexpected AC shutdown.
Strange Noises
When summer comes around, the sounds of birds chirping and barbecues sizzling are commonplace, but if you hear some strange noises coming from your air conditioner, it’s best to turn off the system and call in a professional. Certain sounds, such as rattling and buzzing, indicate more serious issues like electrical problems or compressor issues that require the expertise of a certified technician to resolve.
A rattling sound is most often caused by loose parts in your air conditioning unit that are hitting against each other while running. This can be a result of foreign objects like twigs or small toys that find their way inside the unit or due to expansion and contraction in ductwork that causes components to rub against each other.
Repeated clicking sounds are not normal, and they typically indicate that there is an issue with the contactor. This is a part that moves electricity between the fan motor and compressor, so it’s important to get this fixed right away. Continuing to run your AC with this problem can cause further damage to the fan and compressor, so it’s best to leave this type of repair to a professional.
Low Frequency Noises
Millions of Aussies rely on their air conditioners to regulate temperature and humidity, and when they fail, it can have serious health repercussions. For example, if the AC malfunctions and fails to cool the home effectively, it can cause sweating which can lead to dehydration or even heat stroke. This is especially dangerous for elderly people or young children who might not recognise the symptoms of these conditions.
Fortunately, the majority of HVAC problems can be easily diagnosed with routine maintenance. For instance, a simple inspection with a thermal imaging camera can quickly identify hot or cold spots in the system which might suggest blockages or refrigerant leaks.
Air conditioning systems are intricate and consist of many components that work together to control temperature. One of the most crucial is the compressor which is responsible for circulating refrigerant and facilitating heat exchange. When the compressor malfunctions, it may produce screeching or banging noises that require immediate repair.
Sensor problems are another common AC repair issue that can be quite disruptive. They may occur when the sensors are dirty or misaligned. They can also be caused by a lack of airflow through the ductwork. This can be the result of undersized ducts, blocked vents, or loose duct sections. Addressing this problem often requires a thorough inspection and cleaning of the ductwork. It may also be necessary to replace parts of the evaporator coil.
Faulty Thermostat
The thermostat is an essential component of any air conditioning system. When it’s working correctly, it ensures that your home or workplace stays at a comfortable temperature while minimizing energy consumption. However, like any other mechanical system, your thermostat may experience issues that require AC repair in order to function optimally.
One of the most common signs that your thermostat isn’t working properly is when the display doesn’t turn on. This could be a sign that the batteries are dead or that there is a blown fuse in your home’s breaker box. In either case, replacing the batteries or resetting the breakers should solve the problem and restore power to your thermostat.
Another common symptom of a malfunctioning thermostat is inaccurate temperature readings. If the temperature displayed on your thermostat doesn’t match the actual temperature of your home, this can cause discomfort and unnecessary energy expenses. You can check the accuracy of your thermostat by comparing it to a thermometer.
If you’re still having trouble with your thermostat, it might be time to call in a professional. A trained technician can inspect your unit and accurately diagnose any problems with its internal components. If you suspect that your thermostat is the culprit, they can also recommend an appropriate replacement. It’s important to note that working around electrical components can be dangerous, so it’s always best to leave this task to a qualified expert.
Faulty Compressor
The compressor is a crucial component of your AC that provides the high pressure side to the system. This is why many of the problems that affect your air conditioning are a direct result of the compressor itself. Many issues affecting the compressor can be avoided with routine maintenance.
One of the most common causes of a bad compressor is low refrigerant levels. This may be caused by a leak in the compressor itself or it can be the result of poor work by an unqualified technician who added too much refrigerant to your system. Leaks can be caused by worn or damaged seals, pistons, or bearings in the compressor. A faulty compressor can also lead to ice build-up on the indoor evaporator coils and reduced cooling efficiency.
Another common problem with the compressor is the start capacitor failing. The capacitor is responsible for sending electricity to the compressor’s motor to make it run. If you hear buzzing coming from the outside unit or the thermostat doesn’t seem to respond, this is a sign that the compressor needs repair. This should only be done by a professional as the capacitor stores extremely high voltages that can cause injury or death to an inexperienced person. This is just another reason that regular AC preventive maintenance is essential to the longevity of your system. It can help you avoid costly repairs and keep your air conditioning running efficiently.
Faulty Fan
A broken fan can be a huge problem. It can mean little to no airflow, loud rattling sounds, or even an unexpected shutdown. Regardless of the issue, it’s vital to call an AC repair specialist for help as soon as possible to avoid major damage.
In some cases, a simple fix can be all that’s needed. For instance, if the fan isn’t turning on, it may be due to a blown fuse or tripped circuit breaker. While it’s tempting to try to fix this yourself, working with electrical components can be dangerous without proper training and equipment.
Another potential cause is a capacitor failure. Capacitors store voltage and transmit it to the motors to start and run them. Over time, they can wear out or get damaged from excessive stress, making them useless. Luckily, replacing a capacitor is usually an easy job for our technicians.
Alternatively, issues with the thermostat can also cause the fan to stop working properly. If the thermostat is set up incorrectly or the sensors aren’t functioning correctly, it could send wrong signals to the fan. This could result in the fan overheating and leading to system failure. Fortunately, a thermostat or sensor replacement is also a quick and inexpensive AC repair. It won’t take more than an hour or two for our team to make this repair. Lastly, it’s worth noting that extremely low prices are often a red flag, indicating subpar services and inexperienced technicians.
