Spring Time A/C Check
Now that the hot weather is very close it’s time to start thinking of your air conditioning system. Most people think you just turn it on and if it works your good to go. That’s only part of the story, there is some maintenance that should be done to ensure the system is at it’s full capacity. First lets take a quick look at the system itself. Open the hood and take a look at all the hoses and compressor, is there any trace of oily deposits at hose connections or anyplace in the system? If so you may have a leak at that point. The refrigerant in the system carries oil in it to lubricate the compressor, as the refrigerant leaks out it will leave a tell tail sign in the form of an oily deposit. Check the condenser to make sure it is clear of dirt and leaves. A blocked condenser can lead to excessively high, high side pressure, reducing cooling efficiency. Make sure the compressor drive belt is in good condition and not loose. You may also want to check the evaporator drain tube for any blockage. A clogged drain tube can lead to some very wet carpets and a musty smell inside the car. This is also a great time to check and replace the cabin air filter if your car is equipped with one. If the system still does not cool properly or not at all it’s time to check system pressures. Low or no pressure would indicate a low or empty system. It is extremely important to have the correct type and amount of refrigerant charge in the system, to little or too much refrigerant will adversely effect performance. It is highly recommended taking your car to a trained pro to take care of the recovery and charging of refrigerant. It is against the law to vent CFC refrigerants into the atmosphere.
