AC Service & Repair

When is AC Service or AC Repair Necessary?

  • Whenever you notice any issues in performance. (i.e. not cooling)

What Does Service Include?

  • In depth inspection of lines and hoses.
  • Test and record the systems high and low-pressure readings.
  • Check and record the temperature of the air from the air conditioning vents at maximum cool setting.
  • Freon cleansing; because freon is harmful to the environment, we take special care to use the proper recovery machines to ensure that none of the material escapes during service.

Special Considerations:

The Environmental Protection Agency determined that Freon known as R-12 or CFC-12 was damaging the ozone layer and stopped production of the material. Now R-12 Freon is hard to find and very expensive. Although most vehicles produced before 1995 use R-12 in their air conditioning systems our Technicians can retrofit your vehicle to the new approved R134a. R134a is a more environmentally friendly freon. This retrofit is more cost-effective than attempting to repair the older systems.


R134a Retrofit Service:

  • Case by case evaluation of what will be needed.
  • R-12 Freon is recovered along with the R-12 oil and properly disposed of according to EPA regulations.
  • The system is flushed.
  • Install the R134a retrofit kit (a small number of vehicles may require different seals and hoses).
  • Evacuate and recharge the system with R134a freon and compatible oil.
  • Install mandatory retrofit labeling.
