Car & Truck Air Conditioning - Why Do I Need to Service It?

Your heating, ventilating and car air conditioning system (HVAC) keeps your car interior comfortable in any season by providing the right temperature and humidity level. The HVAC system also helps improve defroster operation. 

Typical Car or Truck Air Conditioning Service

• A thorough inspection of your car's HVAC system should be performed annually.
   
• A service technician checks pressures to test operation, refrigerant charge and outlet temperatures.
   
• If the system is found to be low on refrigerant, a leak test is performed to find the source of the leak.
   
• Refrigerant may be added if necessary to "top off" the system (some states do not allow "topping off").
   
• A technician may also check for evidence of refrigerant cross-contamination, which is the mixing of refrigerants.
   
• A/C service should also include a check of the compressor's drive belt and tension.
   

Questions to Ask About Your Air Conditioning System

• What happens if I continue to use my car air conditioning system, even though it's not cooling properly?
   
• Water drips underneath my car or truck when I use the air conditioning system. Is this normal?
   
• A musty odor comes out of the car air conditioning vents at times. Can anything be done about this?
   
• My truck air conditioning system seems to cool intermittently and I hear a clicking on and off from underneath the hood. What does this mean?
