Car AC Repair Services in Great Falls, VA

We provide comprehensive auto air conditioning repair services to keep your car comfortable no matter the weather in Sterling. Our expert technicians are trained to diagnose and fix your vehicle's cooling system efficiently and affordably.



AC Diagnostic Service

We begin every vehicle AC repair with a comprehensive diagnostic assessment to determine why your air conditioner isn't performing as expected.

Common problems we diagnose include:

• Weak airflow
• Unusual odors from vents
• Temperature fluctuations
• Strange noises during operation
• Refrigerant leaks

There is no charge for this inspection if you move forward with the repair and we'll give you an estimate of how much it will cost.

Compressor Repair

We specialize in repairing and replacing faulty compressors that may be causing your air conditioning to blow warm air.

Compressor issues often arise from low refrigerant levels or electrical problems within the system, which could be why your car doesn't produce cold air. We handle all compressor types across various vehicle makes and models.

Condenser Repair

Your car's condenser releases heat from the refrigerant. When it becomes damaged or clogged, your car's air conditioner performance significantly decreases. Common condenser problems include debris blockage, leaks from road damage, or internal corrosion.

We thoroughly inspect condensers for damage and provide expert repair or replacement services if needed.

Evaporator Repair

The evaporator absorbs heat from your car's cabin air to create cold air. Evaporator problems often manifest as inconsistent cooling or musty odors from your vents. These issues typically result from mold growth or physical damage to the evaporator core.

We carefully inspect the evaporator for leaks, corrosion, or blockages. We can clean, repair, or replace your evaporator as needed.

Thermal Expansion Valve Repair

The thermal expansion valve (TXV) regulates refrigerant flow through your AC system. When this valve malfunctions, it can cause erratic cooling or complete system failure. Issues often stem from valve clogs or internal component damage.

We test valve operation and refrigerant flow to identify problems. Our technicians are skilled at replacing this item if needed.

Refrigerant Recharge

Low refrigerant levels are a common cause of poor AC performance. We provide professional refrigerant recharging services to restore your system's cooling capability. Refrigerant loss typically indicates a leak somewhere in your AC system.

We first locate and repair any leaks before recharging your system with the exact type and amount of refrigerant specified for your vehicle.

7 Signs that Your Vehicle's AC Needs Service

1. Weak or No Cool Air
   When your AC blows warm air or barely cools, it's often a sign of low refrigerant or a failing compressor.
2. Strange Noises
   Unusual sounds like grinding, squealing, or rattling when the AC runs usually indicate problems. These noises shouldn't be ignored as they can lead to complete system failure.
3. Foul Odors
   Bad smells coming from your vents often mean mold or bacteria growth.
4. Water Leaking Inside Vehicle
   Puddles on your floor mats might indicate a clogged drain tube in your AC system. This issue is common but needs attention to prevent moisture damage to your car's interior.
5. Refrigerant Leaks
   Spotting fluid under your car or hearing a hissing sound could mean you have a refrigerant leak.
6. AC Cycles On and Off Frequently
   If your cooling system keeps cycling rapidly, it may indicate an electrical issue or failing component.
7. Dashboard AC Controls Not Working
   Unresponsive buttons or knobs often point to electrical problems in your climate control system.
