Automobile Air Conditioning Systems are comprised of many components, such as hoses, which transport the refrigerant throughout the air conditioning system, and seals which maintain the closed system. Unless periodiclly inspected and maintained on a routine basis, A/C system hoses and seals can become brittle, developing cracks and allowing the refrigerant/lubricant to escape – leading to efficiency loss (eg. air is not as cold as it used to be, component failure, increased noise, odors, etc.).
Advantages of a functioning AC system
- Improved Air Quality Warm air passing over the evaporator coils produces condensation or moisture, which tends to collect dust & other particulates – removing them from the air you breathe.
- Safer Driving During hot weather, a properly functioning A/C System will do its job by cooling the air inside your vehicle’s interior. Studies indicate a comfortable driver is less likely to be involved in an accident. During cooler weather, the A/C system can come into play again, by assisting in the defrost process of your vehicle’s windows. Cool air contains less moisture; therefore, windows can be defrosted quicker by using the air conditioning system.
- Fuel Economy A car will tend to obtain better fuel economy ratings as its shape becomes more aerodynamic. Vehicles having more aerodynamic shapes tend to travel along with less resistance and thereby consume less power or fuel necessary as they are being “pushed” through the atmosphere around us. One way you can ensure your vehicle is at its optimum aerodynamic state, is simply by keeping the windows rolled-up. A properly functioning Air Conditioning System allows us to do this during hot weather by maintaining a cool and comfortable environment inside your vehicle.
- Increased Resale Value “Does the A/C work?” Is a question you will likely hear when selling your automobile to a private party.
