A/C Diagnostic & Repair

Here in Orange County your Air Conditioning system is not really a luxury but a necessity, especially during the hot summer months. If your Air Conditioning fails driving is going to get uncomfortable fast! At Expertec Automotive we are can service or repair your AC system quickly and efficiently while protecting the environment, we use specialized equipment to capture and recycle the Freon your air conditioning runs on to protect against air pollution.

How Does The Air Conditioning Work?

The Air Conditioning in your car does not actually create cold air, it takes the existing air in your car and removes the heat and moisture from it returning cooler air to the cabin. This process occurs by passing Freon through the AC system. The Freon is a gas, when the system is turned on the compressor increases the pressure of the gas which causes it to heat up, it then passes through the condenser which works a bit like a radiator and cools the Freon causing it to turn into a liquid which then travels to the expansion valve which reduces the pressure and cools the liquid turning it into a gas which then passes through the evaporator, the fan blows the warm air through the evaporator which is cooled as it passes though and cold air comes out of the vents in your car. Once the gas has passed through the evaporator it travels back to the compressor where the process begins again.

Air Conditioning Issues

Unlike many issues you may have with your car it is extremely easy to tell you have an issue with your Air Conditioning. The main issues you are likely to come across are;

  • No air or low air pressure coming out of the vents
  • Hot air coming out of the vents
  • Bad smells coming out of the vents


There are many possible causes for these issues, but our expert technicians can quickly diagnose and repair the source of your AC problems.

Auto Air Conditioning Recharge Service

If the levels of Freon in the system drop then it will become less effective and the air coming out of your vents will not be as cool. A Recharge is simply adding additional Freon into the system to bring it back up to manufacturers specifications. While this will usually resolve the issue sometimes a reduction in the coolness of air being delivered is indicative of a bigger issue.

AC System Repair

The Freon travelling through your AC system between the heating and cooling elements does so in rubber hoses. Over time these hoses and the seals connecting them to the elements start to age and lose elasticity, when that happens it allows both the Freon to escape and moisture to enter the system. When Freon and moisture come into the contact the chemical reaction causes a corrosive acid to be formed which will start to corrode the system from the inside out.

At ExperTec Automotive we clean the A/C lines, evaporator and ventilation system. Then a biocide is used to kill all bacteria, mold and fungi. The ventilation system and interior are deodorized. The air inside your vehicle will be much healthier, smell great and the A/C will run 4 to 5 degrees cooler due to increased efficiency.

If your AC system is not as cool as it once was then come into one of our three Orange County locations and have your system inspected. Whether you simply need a recharge or a more comprehensive system repair our ASE certified technicians will get you back to driving in cool comfort in no time.
