Does Your Vehicle Require R-1234yf Refrigerant?

Until 2018, most cars’ cooling systems used R-134a refrigerant. Now, car manufacturers are using a more advanced automotive refrigerant known as R-1234yf. This type of refrigerant breaks down more quickly than the older version, which is better for the environment. At Lockett’s Auto Care, our team can examine your vehicle to determine if you need R-1234yf refrigerant.

Common AC Services at Lockett’s Auto Care

Some of the most common services that we provide at our car AC repair shop in Catonsville include:

  • Cabin air filter – Your vehicle’s cabin air filter cleans the air that comes into the cabin from outside the vehicle. The air filter is crucial to reduce allergens and odors in the cabin.
  • Compressor – The AC compressor in your vehicle is crucial to keep your vehicle cool. If you hear noise from your car’s belts or your vent fans stop blowing cold air, it’s time to visit Lockett’s Auto Care for our auto AC and heating repair services.
  • Condenser – Your car’s condenser removes the heat from the refrigerant that cools the cabin. If you smell burning while your AC is on, your condenser may need to be adjusted or replaced.
  • Blower motor – When your vent fans only work at high speed or don’t work at all, this may be a sign that the blower motor isn’t working properly.
  • Evaporator – Your vehicle’s evaporator pulls the heat from the evaporator coil and keeps the refrigerant as cold as possible. It is critical to keep your car’s evaporator working.
  • Refrigerant recharging – In some cases, your vehicle’s AC isn’t working because the refrigerant needs to be recharged. Our ASE-certified technicians can recharge the refrigerant and keep your car cabin cool.


If you do not suspect a window or sunroof leak, an AC system leak may be the culprit. Common car A/C leaks can be caused by clogged evaporator drains, a leak in the evaporator core, or faulty seals.
If your vehicle is blowing warm air despite the AC being turned on may be an indication of a leak in the HVAC system, an electrical issue, a fault in the AC compressor clutch, or a failure with the expansion valve.
When a vehicle’s AC fails to blow air, or the pressure is reduced, an air blockage may be the cause. Additionally, this may signal that the AC blower motor is failing, or that the evaporator core is restricted.


The weather in Maryland is unpredictable, so you need your vehicle’s AC and heating to work at optimal levels. Our Lockett’s Auto Care team is ready to help. Learn more about our auto air conditioning repair in Catonsville today by calling 410.744.4328.
