The air condition system in your car is serviceable item, just as you to change your oil and air filters from time to time.
It is very important to maintain your air conditioning system for the following reasons: Fungi and bacteria can grow in car A/C systems and can cause allergic reaction such as hay-fever, skin irritations, running noses and itchy eyes.
Natural leakage occurs through slightly porous pipes; most A/C systems will lose around 15-20% refrigerant every 12 months resulting in less powerful and less efficient.
If not service regularly, you A/C system will put strain in the compressor which can result I the compressor wearing quickly, as well as causing costly. Increased fuel consumption as it draws more on engine power to run the system.
