Frequently Asked Questions

What kind of AC repairs do your technicians perform here in Round Rock?

ABC skilled technicians have experience addressing all kinds of air conditioning issues, no matter the make or model.

Our team of skilled technicians are frequently called to Round Rock homes.

The common AC problems they handle include:

Refrigerant Leaks

When your refrigerant is not at manufacturer-recommended levels, you may notice your AC having a harder time cooling your indoor air. Since your system should not lose refrigerant over time, these problems are usually associated with a leak or not having the right amount in your unit when your AC was installed. Inhaling refrigerant is extremely dangerous and can lead to potential respiratory issues, so the best way to troubleshoot a refrigerant problem is calling in a qualified HVAC professional. ABC’s qualified technicians can locate the source of your leak, make any needed repairs and get your refrigerant back to the right level.

Frozen Evaporator Coil

Your evaporator coil is the part of your AC system that brings your air to the desired temperature. If airflow is compromised, usually because of a dirty filter, this component can freeze. ABC’s experts can pinpoint the source of the problem and resolve any issues that could be compromising the proper functioning of this important part of your AC.

Lack Of Regular Maintenance

Proactive maintenance measures help your unit last longer and work more efficiently. Frequent check-ups also help you avoid those unwelcome and often expensive repairs. While you can change our your filter frequently, most of the diagnostic checks that will keep your unit running at peak performance are best performed by an AC professional. ABC’s knowledgeable technicians can carefully check every part of your system on a regular basis and test your unit’s performance to ensure everything is operating smoothly.

Electrical Issues

While there are ultimately a number of reasons your air conditioning unit could have stopped working, electrical problems can be one of the possible culprits. Whether you are dealing with a breaker issue or wires that are corroded, frayed or otherwise faulty, ABC can address any problem you may be having that disrupts the electrical flow from your AC and keeps it from working.

Malfunctioning Thermostat Sensors

When the sensors that direct the operation of your AC system get out of position, the temperatures it displays will be incorrect, causing your unit to heat or cool your house incorrectly. ABC’s experts can handle this problem quickly so that your system once again gets your living spaces to the desired temperature.

Energy Inefficiencies

You may be able to get better performance out of your current system by adding insulation to your attic, ensuring your ductwork is installed and sized correctly, applying a solar film to your windows and improving your indoor air quality. ABC’s team of specialized technicians can also assist you in identifying rebates and other incentives you might qualify for to lower your up-front costs.

Drainage Problems

Moisture build-up often leads to rusty parts, which lead to both your system underperforming and your condensate drain becoming clogged. Typically, these problems stem from improper unit installation, which is something our technicians can quickly identify and correct.

What other services does ABC provide for air conditioners?

Our qualified technicians can replace your entire system, perform preventative maintenance, suggest energy improvements and make your life easier by helping schedule regular filter deliveries.

Can ABC technicians in Round Rock also fix heaters?

We sure can! While ABC is known for our reliable and expert AC service and installation, our skilled technicians are also qualified to handle routine maintenance for heaters, as well as taking care of any needed repairs.

How do I know when I should begin the search for a new air conditioner?

The answer varies from case to case, but generally, it’s best to start considering an upgrade once the cost of maintaining your system has gotten close to the cost of purchasing a newer model. Basically, if you find yourself making repairs several times a year for at least a year or two in a row, you should probably begin looking into making this investment.

Another factor to consider when doing your research is energy efficiency. Updated models can end up saving you close to 40% on the cost of cooling your house. These savings add up tremendously over time.

Need to talk? ABC’s heating and cooling professionals are happy to sit down with you to provide answers to any questions you might have about purchasing and installing a new unit. We can help you weigh the pros and cons for different units, and also provide you with information on what rebates or financing might be available.

To give our customers and added peace of mind, we offer a one-year guarantee to anyone who takes advantage of our installation services to ensure you’re completely satisfied with your purchase.
