Low air, warm air, or a system that works some days and not others usually points to a leak, not just a low charge. We find the leak first — topping off a leaking system is money out the window.
We service both A/C and cabin heat, including blower motors and blend door faults.
Common car A/C problems we fix
- A/C blowing warm or only slightly cool air
- Air that's cold at highway speed but warm at idle
- A/C that works some days and not others
- Weak airflow from the vents even on high
- Blower that only works on certain speeds
- Clicking, rattling, or squealing when the A/C turns on
- Musty or mildew smell from the vents
- Water on the passenger floor
- Heat that won't turn off — or won't come on in winter
Why a simple recharge usually isn't the fix
Your A/C is a sealed system. If it's low on refrigerant, the refrigerant went somewhere — a leaking O-ring, a pinhole in the condenser from road debris, a worn compressor seal, or a corroded evaporator. A can of refrigerant from the parts store may get you cold air for a week, but it doesn't fix the leak, and overcharging a system can damage the compressor.
We check pressures, use dye and electronic leak detection to locate the leak, repair it, then evacuate the system and recharge it with the exact amount of refrigerant your vehicle specifies. That's how the repair lasts.
How we diagnose your A/C system
A/C problems fall into three groups: refrigerant problems (leaks, low charge, contamination), mechanical problems (compressor, clutch, condenser fan), and control problems (blend doors, blower motors, resistors, pressure switches, and climate control modules). We test each one rather than guessing.
We measure high- and low-side pressures, verify the compressor clutch engages, confirm the condenser fan runs when it should, check vent temperatures, and test the electrical controls. If the air is cold at the evaporator but warm at the vents, the problem is airflow or a blend door, not refrigerant — and that's a very different repair.
A/C and heating repairs we perform

- A/C compressor and clutch replacement
- Condenser and evaporator replacement
- Expansion valve and orifice tube replacement
- Condenser and radiator fan repair
- Blower motor and blower resistor replacement
- Blend door actuator diagnosis and repair
- Heater core and thermostat service
- Cabin air filter replacement
Texas heat and your A/C
In Garland, the A/C runs hard from late spring into fall, and it works hardest when you need it most — stuck in afternoon traffic with the sun on the windshield. That load ages compressors, fans, and hoses faster than in milder climates. Running the A/C for a few minutes every couple of weeks during cooler months keeps the seals lubricated, and replacing the cabin filter on schedule keeps airflow strong.
If you notice your A/C gradually getting weaker each summer, that's a slow leak. Catching it early is almost always cheaper than waiting for the compressor to fail.
Don't forget the heating side
The same climate system that cools your car also heats it and defrosts the windshield. A failing thermostat, low coolant, a clogged heater core, or a stuck blend door can leave you with no heat on a cold morning — and no defrost, which is a safety issue. We diagnose and repair both sides of the system.

R-134a vs. R-1234yf: why your car's age matters
Most vehicles built before the late 2010s use R-134a refrigerant. Many newer vehicles use R-1234yf, a refrigerant with a much lower environmental impact that requires different service equipment and costs more per pound. The two are not interchangeable, and mixing them can damage the system and contaminate shop equipment. We check the label under your hood and service your system with the correct refrigerant and the exact charge your manufacturer specifies.
How long should a car A/C repair last?
When the root cause is fixed — the leak sealed, the failed part replaced, the system properly evacuated to remove moisture, and the correct charge installed — an A/C repair should last for years. Repairs that fail quickly usually skipped one of those steps. Moisture left in the system can form acids that corrode components from the inside, and an incorrect charge forces the compressor to work harder. That's why we follow the full process every time rather than just topping off.
Simple habits that help your A/C last
Park in the shade or use a windshield sunshade when you can. On very hot days, drive for a minute with the windows down before switching to recirculate, which lets the system cool already-cooled cabin air instead of fighting outside heat. And if you hear a new noise or smell something unusual when the A/C turns on, have it checked before a small issue becomes a compressor replacement.

Car A/C Repair FAQs
How much does car A/C repair cost?+
It depends entirely on the cause — a leaking O-ring is a small repair, a compressor is a large one. That's why we diagnose first and give you the price before any work starts.
Can I just add refrigerant myself?+
You can, but it doesn't fix the leak, and overcharging can damage the compressor. Newer vehicles also use R-1234yf refrigerant, which requires different equipment.
Why does my A/C smell musty?+
Moisture on the evaporator can grow mold and bacteria. A new cabin filter and an evaporator cleaning usually solve it; a clogged drain that leaves water on the floor may also need to be cleared.
Why is my A/C cold on the highway but warm at stoplights?+
That's often a condenser fan problem or a low refrigerant charge. At speed, air flowing through the grille cools the condenser; at idle, the fan has to do that job.
Do you service A/C on newer cars?+
Yes, including vehicles that use R-1234yf refrigerant. We check your system's label and service it with the correct refrigerant and charge.
