Auto
A/C Service Question No. 7
The
complaint on the A/C system is that it isn't blowing cold enough.
You've been told the duct outlet temperature is 55°F
(or about 13°C). You should just recharge the system
because it's probably just low on refrigerant. |

Auto
A/C Service Question No. 8
It's
70°F (or about 21°C) outside. You connect pressure gauges to the
A/C system and static pressure gauge readings
are about 50 psi. You should just add refrigerant
because it's probably low. |

have to flush the system because the vehcile manufacturer said
so. |

want a leak detection method that will work all the time.

the leaks. |
