AC Repair Round Rock TX involves inspecting, troubleshooting and repairing air conditioners in homes or businesses. This can include a variety of tasks, from cleaning clogged filters to replacing damaged parts.

Prior to beginning any work, the service technician will make sure that the power to the AC unit is turned off by checking the circuit breakers. They will also check and clean the evaporator coils to avoid dust build-up.

While summer brings many wonderful sounds, including birds chirping, barbecues sizzling, and lawn mowers roaring, one sound you definitely shouldn’t hear from your air conditioner is a screeching or banging noise. These unusual sounds can be a sign of an AC issue that could grow into something much more expensive and dangerous if left untreated. 

Clicking noises from your indoor air conditioning unit are often caused by loose or misaligned parts. If you’re comfortable working with your air conditioning unit, you might be able to tighten or re-align these parts yourself. However, electrical problems inside your air conditioner are usually not DIY-friendly, and the wrong fix may lead to additional damage and escalating repair costs down the road.

Rattling noises are usually a result of an AC fan bearing or motor problem that needs to be re-lubricated. If these issues aren’t repaired promptly, they may damage the internal wiring and cause electrical problems inside your unit. If you suspect that this is the case, turn off your air conditioner and contact a licensed professional right away.

Buzzing or humming noises are usually signs of electrical problems within your AC system. These issues can be extremely dangerous and should only be dealt with by a trained and certified technician.

Hissing sounds can be a sign of refrigerant leaks. These are not only a health hazard, but can also damage your compressor valves if not addressed right away. The best way to avoid a hissing sound is to schedule regular maintenance visits with a qualified AC technician. They will inspect your unit and prevent issues from arising that might eventually cause these hissing sounds to occur. These routine checks will identify and address small problems before they escalate into bigger ones that require costly repairs or replacements.

Your AC Won’t Turn On

A common problem that can keep your AC from turning on is a power supply issue. The cord that runs from the unit to the outlet can become worn or damaged, which will impede the flow of electricity and prevent the air conditioner from starting up. To resolve this issue, you will need to contact a professional to replace the broken cord or repair the outlet.

Another potential culprit is a faulty thermistor. This small sensor inside the unit monitors temperature and sends signals to the compressor and fan, so when it fails, your system may fail to turn on or run efficiently. Luckily, replacing a thermistor is a relatively simple task that requires few tools and shouldn’t take more than an hour.

A clogged drain pan can also prevent your AC from turning on. The float switch in the drain pan is designed to shut off your unit when it’s full of water, so if this switch trips due to a clogged or overflowing drain line, your AC won’t be able to start up.

If the thermostat isn’t set to “cool,” or if the air filter is dirty, your AC will fail to turn on. Double-check that the thermostat is on and set to a cool temperature, and that the batteries are fresh.

You can also check the circuit breaker to see if it’s tripped. If it is, reset it by flipping the switch to the on position.

Fuses can wear down and cause electrical problems, so if your fuse is blowing frequently, it’s time to replace it with a new one. However, if you find that the replacement fuse keeps blowing instantly or quickly after installation, it’s best to call a professional.

Other problems like a blown capacitor, faulty fan blades, or refrigerant leaks are all more serious and require the expertise of a professional. Attempting to make these repairs on your own can pose safety risks, not to mention void your system’s warranty. It’s always better to leave these tasks to the professionals so that they can be handled safely and correctly, ensuring your AC is back up and running in no time!

Your AC Isn’t Producing Cool Air

If your AC runs but isn’t cooling, first check the thermostat to make sure it’s on and set to ‘cool.’ This simple step is often enough to kickstart your air conditioner, and you may be able to find the cause of your problem without any AC repair costs at all!

Next, if you notice cool air only in one or two rooms of your home, make sure that furniture, decor, or appliances aren’t blocking the registers in those areas. You can also try changing the filter to see if that makes any difference. If you can’t figure out what’s causing your AC to run but not produce cool air, it’s time to contact a professional for an inspection and AC repair.

A clogged air filter, dirty evaporator coils, or blocked vents can all hinder your system’s ability to effectively cool your home. You can help prevent these issues from occurring by making sure you change your air filter regularly and keeping your vents clean. It’s also a good idea to clean your evaporator coils annually.

Keeping up with routine maintenance can help you avoid many of the problems that can cause your AC to fail. It’s recommended that homeowners get a professional inspection, checkup, or tune-up every 30 to 90 days, depending on the type of air conditioning system they have.

During an AC service, your technician will look at the performance of all components, including the blower motor, compressor, and evaporator coils. They’ll also look for signs of trouble like unusual noises, foul odors, and a refrigerant leak. If your system is nearing the end of its lifespan, your technician will explain the options for upgrading it or replacing it entirely. It may be more cost-effective to replace your entire HVAC system than to keep repairing the old one.

Your AC Isn’t Working

Getting stuck on a hot, sunny day with a malfunctioning AC is no fun at all. The good news is that a few troubleshooting tips can help you find the problem and make your air conditioner work as it should again.

Start by ensuring that all power switches on the AC unit and around it are switched on. Then check the breaker box to see if one of the breakers has tripped. This is common when you use too many appliances at once or if there’s a power surge after a storm. Resetting the breaker can usually fix this issue.

Next, look at the outdoor unit (condenser) to make sure nothing is obstructing or blocking its airflow. Make sure there are no fences, bushes, or other debris within 2 feet of the condenser and that it’s not covered with leaves or weeds. If you do notice a blockage, clearing it can be as easy as using a garden hose to spray off the dirt and grime.

You should also check the drain pan and line for a clog. When your AC system runs, it creates condensation that exits through the drain line. If the drain pan becomes full or clogged, this can trigger a safety switch and turn off your unit. Clearing the drain line with a wet/dry vac or pipe snake can usually solve this problem.

Another reason your AC might not be cooling is because the blower and fan aren’t working correctly. If the blower motor or fan motor fails, it can’t move the air from your home to the outside air and vice versa. This is a more complicated repair, but it’s one that you can perform yourself with a few tools and some time.

The best way to prevent expensive AC repairs is to schedule routine maintenance twice a year. These visits can identify problems before they become major issues, and they’ll help extend the life of your system. If you’re ready for a new HVAC system, Carrier offers energy-efficient replacements with zero upfront cost and guaranteed savings. Tap here to see if you qualify.

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.
