Car Service La Mesa offers air conditioning repair services for vehicles throughout San Diego County. Our knowledgeable mechanics understand how challenging driving around San Diego County when your air conditioner stops functioning correctly can be; that is why our skilled technicians are available to quickly identify and resolve any air conditioning issues in your vehicle.

Like any mechanical system, car air conditioning systems can encounter issues that disrupt their functionality. Keeping up with regular AC maintenance can prevent these issues from arising.

Expansion Valve

The expansion valve transforms the high pressure and hot refrigerant from the compressor into a low pressure, cold state ready for the evaporator. This is essential for creating the cool air you breathe.

It’s a precision part with delicate moving parts that needs proper lubrication to function correctly. Unfortunately many do-it-yourself mechanics add refrigerant leak stop products to their system, which can clog the expansion valve over time.

Malfunctioning Car AC Symptoms

Symptoms of a malfunctioning car AC expansion valve include warm air blowing or frost forming on the vent nozzles. Replacing this Freon metering device is relatively easy for experienced auto repair technicians. Using the right tools and procedure helps ensure that it is installed correctly to avoid any future problems.

Condenser

The condenser acts as a heat exchanger, releasing heat that would otherwise be trapped in the cabin and potentially damaging components. It’s similar to a radiator in your car and is important for keeping the air conditioning system contaminant-free and functioning at its optimal performance.

The condenser is also essential for preserving the interior of your car, maintaining a cool temperature and preventing fading or damage to upholstery and dashboard materials. It’s important to regularly clean your condenser and inspect it for physical debris like leaves or dirt that can hinder cooling efficiency.

The hot compressed refrigerant liquid pumped through the condenser is cooled down by this radiator-like heat exchanger, before entering the receiver drier and evaporator. A restricted condenser will limit the flow of vaporized refrigerant, which may result in poor cooling performance.

Receiver-Dryer Unit

The receiver-dryer is a component in the car air conditioning system that serves two important functions. First, it acts as a storage tank for liquid refrigerant that is stored until the evaporator needs it.

This also helps to prevent debris, small pieces of metal, and other contaminants from entering the compressor and damaging it. Moisture can also enter the system through the hoses and expansion valve and combine with refrigerant to create an acidic solution that will damage internal components.

The accumulator/receiver drier is a filtering unit that contains a desiccant that absorbs moisture from the air, keeping the refrigerant and lubricants free of contamination. It must be replaced when it becomes saturated with moisture or any time the system is opened to replace other parts.

Blower Motor

A car blower motor rotates the fan that pushes air through the system of ducts and evaporator core to control cabin climate. It can operate at different speeds, depending on the setting of the heater or air conditioning fan speed knob.

Traditional blower motors use a power transistor and resistors to vary fan speed. A power transistor can fail, causing the motor to stop working at all or only at a single speed.

Weaker air flow can also signal a failing blower motor. This is because the motor must work harder to get air through the ducts. This extra work can lead to excessive wear and tear and even shorten the motor’s lifespan.

Coolant Levels

Engine coolant serves the primary function of preventing your car’s engine from overheating. While it doesn’t directly impact your air conditioning, a well-regulated engine coolant level minimizes additional heat burden that the air conditioning must counteract, enhancing overall vehicle performance.

Many people are tempted to top off their own coolant, but this is generally a short-lived solution that may only provide temporary relief. Rather, you should bring your car to our repair shop in La Mesa for an automotive air conditioning service, including a refrigerant recharge. During this procedure, our technician evacuates your system, removes the old refrigerant and replaces it with new, environmentally friendly R-134a. This is a critical step that can save you money in the long run by minimizing damage to your compressor and other AC components.
