Professional technicians can perform routine maintenance on your system to prevent many common AC issues, extend the lifespan of your unit, and improve its energy efficiency. They can diagnose and repair problems such as clogged blowers and fans, faulty capacitors, damaged ductwork insulation, and refrigerant leaks. Contact Air Conditioning Repair Round Rock TX for professional help.
Minor issues like thermostat adjustments or air filter replacements can be done within a single visit, typically within an hour.
There’s nothing worse than turning your thermostat down to cool your home only to find your vents start blowing warm air. This issue is a clear indicator that your AC system is in need of professional repair. If you’ve tried the quick fixes like changing your filter and clearing debris obstructions, it might be time to call in the repair cavalry. AC repair technicians come equipped with specialized tools and testing equipment to quickly diagnose the root cause of your AC malfunction.
Faulty wiring and blown fuses are common culprits in AC repair cases. These issues can prevent vital components from completing their jobs and cause your system to run inefficiently. A repair technician will check for any electrical issues and verify the functionality of safety controls, sensors, and other crucial components.
A clogged condensate line is another common reason for your AC to stop cooling and start blowing warm air. This problem typically occurs due to mold and algae buildup that causes your unit to obstruct the flow of condensation. Regularly inspecting and cleaning your air conditioner drain line will help reduce the chances of this happening in the future.
The most severe issue that could cause your HVAC to start blowing warm air is a faulty compressor coil. This is a job best left to a professional as it requires opening up the compressor unit. A faulty coil can lead to costly repairs, so it’s always better to get it checked out right away.
Another common reason your AC might be blowing warm air is low refrigerant levels. A professional will open up the compressor unit and add a fresh charge of refrigerant, which will allow your system to fully cool. A leaking refrigerant line is another serious issue that should be addressed immediately as it can cause severe damage to your system.
Other signs that your AC is struggling include high energy bills without explanation, squealing or rattling sounds, strange odors, and frequent on/off cycling. If your HVAC is over 15 years old, it may be a better investment to replace it instead of investing in AC repair services.
Frozen Evaporator Coil
The evaporator coil is a key component that pulls latent heat from indoor air to prepare it for cooling. However, if this coil becomes encased in ice, it can’t absorb any more heat and will soon stop working. The good news is that the cause of this problem is relatively easy to identify.
Dirt and debris build up on the evaporator coil over time, insulating it and preventing it from absorbing heat. That’s why regular cleaning is an essential part of our AC tune-up service. This will help ensure that the evaporator coil receives the airflow it needs to continue working properly.
Another possible culprit is a blocked return airflow. This can be caused by closing too many of your home’s air vents or unintentionally blocking them with furniture, rugs and other objects. Similarly, a dirty air filter can block the necessary airflow to the evaporator coil, hindering its ability to work correctly.
Fortunately, there are ways to prevent these problems from occurring. If you suspect your air conditioning system is suffering from a frozen coil, the first thing you should do is turn off the unit. This will prevent any further damage to the evaporator coil and other components and ensure that it has an opportunity to thaw naturally.
If you want to speed up the process, you can try turning your air conditioner on to a fan-only setting. This will force warm air over the evaporator coil, which can help it thaw more quickly. It’s also a good idea to contact a professional for further inspection and repairs if you notice that your evaporator coil is frozen.
While most of these problems will require expert inspection and repair, you can take several steps to improve your chances of fighting back against the summer heat. Make sure you’re not closing too many of your home’s air ducts, clean the air filter regularly, and consider joining our annual maintenance plan to keep your air conditioner running its best!

Low Refrigerant Levels
When an air conditioning system is low on refrigerant, it will not be able to properly cool the indoor air. A loss of refrigerant will reduce the ability of the evaporator coil to absorb heat from the indoor air and transfer it outdoors. The result will be warm air pumping out of the vents.
There are several possible causes for a low refrigerant level in an AC unit. One possibility is that there may be a leak somewhere in the system. In this case, the technician will need to find and repair the leak. Another possibility is that the evaporator coil has frozen, which will prevent refrigerant from passing through it. In this case, the technician will need the help of a special tool to thaw out the coil and restore normal refrigerant flow.
A third possibility is that the evaporator coil simply needs to be replaced. This is a common problem and can be relatively inexpensive to fix. A final possibility is that the compressor itself has a problem. This can be difficult to diagnose, but the most likely culprit is an issue with the compressor clutch or motor.
If a professional technician simply recharges your system with additional refrigerant, it will be back to its peak performance shortly. However, this method does nothing to address the underlying problem that has caused the refrigerant to leak in the first place.
A professional air conditioning technician will be able to correctly diagnose the reason that your refrigerant levels are low and take the proper steps to repair it. This will ensure that your system is able to effectively cool your home for years to come. In addition, regular maintenance services can catch problems like low refrigerant levels before they become serious and require expensive repairs down the road. For this reason, many service companies offer both refrigerant top-off services and leak detection/repair services together to save time and money for their customers. This allows them to provide both services during a single visit instead of having the customer schedule two separate visits from different technicians.
Faulty Thermostat
If you turn on your air conditioning and the system never kicks in, the thermostat could be broken. This is a common AC repair issue that requires professional attention, but in the meantime you can try a few simple troubleshooting steps.
The first thing you can do is check if the thermostat has power. If the display screen is dark or blank, even with fresh batteries, it’s likely that the thermostat has stopped working. You can also check the circuit breaker to see if it has been tripped. Often, simply flipping the switch back on will restore the device’s functionality.
Another sign of a faulty thermostat is if nothing happens when you change the settings. In some cases, the thermostat’s electrical or mechanical components will need to be cleaned. This can be accomplished by shutting off the power source and removing the thermostat cover. You can then use canned compressed air or a brush to clean away dirt, soot, cigarette smoke and dust that have accumulated over time. After the thermostat is cleaned, you should replace the cover and turn the power back on.
A faulty thermostat can also be the cause of a short-cycling system, wherein your HVAC unit runs briefly and then turns off before turning back on again. This can lead to higher energy bills and lower comfort levels, so if you notice this issue, it’s important to get it fixed as soon as possible.
Finally, a faulty thermostat can be caused by problems with the internal wiring. Over time, the wires can become frayed or damaged, which cuts off communication between the thermostat and your HVAC system. This may be a sign of a serious electrical problem, so it’s best to leave any repairs or replacements to a licensed HVAC professional. By watching for these signs of a faulty thermostat, you can save money and prevent further damage to your HVAC system. If you’re unsure of what to do, contact a licensed professional to help you diagnose and fix the problem quickly. They can determine whether your HVAC unit needs a repair or a replacement and recommend the best solution for your situation.
