It is normal for the refrigerant to leak a minimal amount (less than an ounce every year), but a more significant leak may cause trouble. Leaks In The AC Systemsīecause of the operating pressure in the hoses and other components, everything must be tightly sealed. The most common problems and the AC repair cost will be discussed in the next section. Air and moisture will cause many problems if they are in the system.ĭepending on the problem, the cost can vary. When filling the AC system, it must be done when there is a vacuum in the system. To comply with that law, a special recovery machine must be used. It is important to note that a faulty AC should be fixed in a professional repair shop.īy law, no refrigerant is allowed to be released into the atmosphere. These possible reasons include a problem in one of the components or a leak in one of the many hoses. Related: How Does A Car Air Conditioning System Work? Cost To Fix A Faulty ACĪs previously mentioned, there are many possible reasons why an AC might not work properly. The heater fan blows air from outside the car through the cold evaporator, thus introducing cold air into the cabin. When the liquid reaches the expansion valve, it is cooled to become a gas again, which then goes through an evaporator. The liquid then passes through the dryer, ensuring no gas is present before the fluid continues to the thermal expansion valve. The hot and pressurized gas then moves into the condenser, where the gas cools and changes into a liquid form. Several pistons compress the air inside the compressor, resulting in heat and high pressure. This process requires the help of a few components.Īt the start of the process, the AC compressor is connected to the engine’s crankshaft by a belt.

Since we provide comprehensive auto air conditioning repairs, our shop is even prepared to rebuild AC compressors that have completely failed. We’re available to replace such components. Perhaps your AC was disabled because the belt on your compressor snapped this could have been the result of a bad drive belt tensioner. Our inspection may come in handy because we often find small, hidden problems before they turn into big ones. If you don’t know what the problem is to begin with, let us examine the compressor, blower fan, and other hardware check the belts and hoses for signs of damage and wear and check refrigerant levels. Our team makes sure to check ambient air temperature before moving forward with car AC recharge service. This is where we refill your car with refrigerant – the type will roughly depend on whether your car was made before or after 1994 – and use a charging hose to bring pressure back up to manufacturer-specified levels. Car AC Recharge ServiceĪ recharge is one of the most common auto air conditioning repairs. Refrigerant levels decrease over time even without a leak, but if you have a dried seal or a loose connection, they’ll decrease that much quicker. If the AC is blowing lukewarm air, the problem may be a faulty fan in the radiator or compressor, or it could be a bent condenser fin, among other possibilities.
