Summer A/C Recharge
A customer's car blows warm air on a 100-degree day. We check the system for leaks, evacuate old refrigerant, and refill to the correct pressure with a dye for future tracking.

Local service
Proudly serving New Braunfels
New Braunfels blends historic homes near the downtown square with newer subdivisions stretching toward the Guadalupe River. Summer heat here is intense, and many properties sit on clay-heavy soil that shifts with the weather. Older houses often have aging A/C systems and engine bays packed tight, while the spread-out layout means breakdowns can happen miles from the nearest shop. The Comal and Guadalupe corridors draw visitors, so reliable cooling and brakes aren't just comfort—they're safety necessities on crowded roads.
Our crew drives to your location anywhere in New Braunfels, from a bungalow off Seguin Avenue to a ranch house on the outskirts. We bring a full set of tools and diagnostic gear in the van, so we handle everything from a check engine light to a serpentine belt swap on the spot. We work in driveways, parking lots, or curbside, laying down mats to catch drips and keeping the area clean. Being based in San Marcos means we're usually thirty minutes or less from most New Braunfels addresses.
Advanced Auto Mobile Mechanic works across San Marcos, TX & the surrounding Hays County area, so a crew is never far from New Braunfels. Call (512) 618-8875 or request a free estimate and we’ll come out and take a look.

What New Braunfels homeowners call us for
A/C Repair & Recharge
New Braunfels summers push A/C systems hard. We test pressures, check for leaks, and recharge to factory spec so you stay cool on the commute or the river run.
Brake Inspection & Repair
Stop-and-go traffic on I-35 and winding roads near the lakes wear pads and rotors fast. We measure thickness, check fluid, and replace components as needed.
Engine Diagnostics & Check Engine Light
Clay soil and heat can jostle sensors and wiring. We plug in our scanner, read codes, and trace the cause—whether it's a loose gas cap or a failing oxygen sensor.
Battery, Starter & Alternator Service
Hot summers drain batteries faster. We test charge output, check starter draw, and replace failing parts so you don't get stranded at the H-E-B parking lot.
Typical projects
The kind of work we take on in New Braunfels
Squeaky Brake Pad Swap
Pads worn down to the wear indicator on a daily driver. We remove the wheels, inspect rotors and calipers, install new pads, and bed them in during a test drive.
Check Engine Light Diagnosis
A persistent code for a misfire. We run a full diagnostic, check spark plugs and coils, and clear the code after confirming the repair—no parts swapped without cause.

Where we work
Across New Braunfels
Downtown New Braunfels
Narrow streets and older homes near the Comal River mean tight parking and limited space. We work curbside or in small driveways, often on classic cars and older trucks with simpler systems.
I-35 Corridor
Stretches of highway frontage with apartment complexes and chain restaurants. We handle quick diagnostics and belt replacements for commuters who need their car back same-day.
Outlying Acreage
Homes on five to twenty acres off Farm-to-Market roads. Longer drives for us, but worth it for customers who need brake work or oil changes without hauling a vehicle into town.
Before work starts

“I can’t say enough good things about Cliff! My daughter’s Mini Cooper developed a problem, and anyone who knows Minis knows they can be challenging to diagnose and work on. Cliff was able to quickly troubleshoot the issue, accurately diagnose the problem, and get it repaired much faster than I expected.”

“Cliff was the most helpful auto mechanic I've ever worked with. After getting a quote at another mechanic in San Marcos at $2700, I wanted a second opinion. Cliff picked up the phone at 8 pm and instantly was helpful. He worked to get me the absolute best prices for the part that was needed.”
