Air Conditioning

Why maintaining your AC System is very important:

Air Conditioning, one of those modern conveniences we all enjoy. If your air conditioning is blowing hot air, or just isn’t blowing cold enough, Lake City Auto Care is here to help. We service all types of makes and model vehicles. Freon, the main component in your air conditioning system is what provides the chemical reaction needed to have that nice cold air to come out of your car, truck or SUV vents. Freon, isn’t like a tank of gas, it is not a consumable item. If your vehicle is low on freon there is a leak somewhere. Be leery of some of these so-called “AC Fix in a Can”. These can contain sealants that can cause internal damage to expensive air conditioning components.

Indications your A/C system may be having issues:

  • If your air conditioning blows only slightly cooler air compared to the air outside.
  • Air that blows in smells like mildew and mold, or feels musty and damping when you enter the vehicle.
  • Your cabin does not warm up in cold weather, or is just a little warmer than outside.
  • The defroster takes longer than typical to operate, or does not operate.
  • Your heater or A/C only functions when driving, not when idling, or quits blowing when the car is stationary.
  • Your heating system blows cold air, or the air conditioning blows warm air
    Low airflow even at the highest fan setting.

Some of the items that can leak or go bad in your air conditioning system include the following:

  • Evaporator
  • Condenser
  • Air Conditioning Compressor
  • Air Conditioning Clutch
  • Expansion Valve
  • Orifice Tube
  • Receiver/Drier
  • Cabin Air Filter

Below is an explanation of each component that has a purpose within the AC unit and functionality. These are the most common components that are checked and serviced when making sure that your AC is functioning as intended

Condenser: The condenser’s primary function is to cool the refrigerator. The condenser dissipates heat released by compressed gases and condenses them into high pressure liquids.

Orifice Tube/Expansion Valve: The orifice tube (also known as the expansion valve) is a controlling mechanism that regulates refrigerant flow throughout the system. It also converts high pressure liquid refrigerant (from the condenser) into low pressure liquid, so that it can enter the evaporator.

Compressor: The compressor is a belt-driven device that compresses refrigerant gas and transfers it into the condenser. The compressor is the core of your vehicle’s air conditioning system.

Evaporator: The evaporator removes heat from the inside of your vehicle. The evaporator allows the refrigerant to absorb heat, causing it to boil and change into a vapor. When this occurs, the vapor leaves the evaporator through the compressor, cooling your car and reducing humidity. The evaporator houses the most refrigerant in the heat transfer process and harmful acids can corrode it. This corrosion typically damages the evaporator beyond repair.

Receiver (Drier): The receiver is a metal container that serves as a storage receptacle for the refrigerant; also known as a drier because it absorbs moisture from the refrigerant and filters out harmful debris and acids. You should change your drier every 3-4 years to ensure quality filtration and prevent any chemical damage.
