When the Texas heat hits, your car’s A/C is more than just a comfort; it’s a necessity. At First Choice Automotive Repair in Killeen, we don’t simply top off your refrigerant and call it a day. Our full car A/C service goes deeper by addressing the root causes of poor cooling performance so you stay cool no matter how high the temperature climbs. If your A/C isn’t performing as it should, don’t wait for the heatwave to catch you off guard. Let us make sure your system is ready for the long haul.
When drivers search for “auto A/C service Killeen” or “car A/C recharge near me,” they’re usually dealing with one thing: discomfort. Maybe the air isn’t blowing cold anymore. Maybe it’s taking too long to cool down. Maybe the system has stopped working altogether.
But what many drivers don’t realize is that the air conditioning system is one of the most technically advanced systems in a modern vehicle. It integrates with your car’s electrical system, its engine performance, and even its computer sensors. That means when something goes wrong, it’s rarely just a matter of low refrigerant.
In other words, if you’re only getting a quick top-off, you’re missing the deeper issues and risking more expensive repairs later.
At First Choice Automotive Repair, a full A/C service is just that: full. It’s detailed, diagnostic, and designed to get your entire system operating like new again.
Here’s what the service looks like from start to finish.
Before we even open the hood, we start by talking with you. We ask questions like:
This conversation helps guide our technicians toward specific components that may be the issue. It’s also part of our relationship-focused process. We want to understand your experience before we diagnose your vehicle.
Next, we conduct a detailed visual inspection of the A/C system. This includes:
We look for obvious signs of damage, corrosion, or component wear. If any part is leaking, cracked, or failing, it will be identified at this stage.
Using high-precision gauges, we check both the high-pressure and low-pressure sides of your A/C system. This tells us:
A quick recharge without this check could overfill the system or hide deeper issues. That’s why we never skip it.
Many modern vehicles have advanced HVAC controls and sensors that communicate with the car’s computer. If any sensor fails, like a pressure switch, temperature sensor, or blend door actuator, it can cause the system to shut down or work incorrectly.
We use scan tools to read these systems and look for:
This step is critical for accurate troubleshooting and is one reason why our technicians are ASE-certified. They’re trained to handle today’s complex electronics, not just mechanical parts.
Leaks are one of the most common causes of poor A/C performance. But they’re also among the hardest to spot with the naked eye. That’s why we use UV dye and specialized detection tools to inspect the system for refrigerant leaks.
We check all fittings, hoses, compressor seals, and the evaporator core for signs of slow or active leaks.
If a leak is found, we’ll repair or replace the affected component before proceeding.
A frequently overlooked part of your A/C system is the cabin air filter. This filter traps:
If it’s clogged, it can severely restrict airflow and make your system feel weak, even if it’s otherwise operating properly.
If your filter is dirty or past its service interval, we’ll replace it with a high-quality unit to restore airflow and protect your interior air quality.
If the refrigerant is low and no leaks are found, we’ll recharge the system using the exact refrigerant type and quantity specified by your vehicle’s manufacturer.
This ensures:
Our refill process is precise. We don’t estimate or “eyeball” it. We recharge the system with certified equipment to deliver accurate, consistent results.
After recharging, we run your system through a full performance test. We check:
You’ll leave knowing your system is not only cooling properly, but is operating at full efficiency for Texas heat.

Consider scheduling a full A/C inspection if:
Don’t wait for the hottest day of summer to find out your system needs help.
In the Killeen area, where high temperatures can stretch over several months, it’s smart to have your vehicle’s A/C system inspected at least once a year. Even if everything seems to be working fine, preventative maintenance can catch wear and tear before it becomes costly.
Yes. When your A/C compressor or other components begin to fail, they often force the engine to work harder, which can increase fuel consumption. A fully serviced and well-maintained A/C system is not only more effective but also more energy-efficient.
Not recommended. A system that’s underperforming may have a low refrigerant level or internal blockage, which can put added strain on the compressor. Continuing to run it in this state can lead to major component failure. It’s best to have it checked promptly.
Most vehicles made after 2015 use R-1234yf refrigerant, while older models typically use R-134a. Some systems can be retrofitted to newer standards, but this requires a technician to determine compatibility and perform safe conversions.
