I brought my 2003 Honda Civic EX last week ago to my work for A/C (air conditioning) service that just stopped blowing cold air (happen last May). I open a hood and spot a lightly black oil (refrigerant oil) around the high pressure service port, obviously leaky Schrader valve. With the engine running, I check the compressor clutch engaged and rotates ok, and radiator/condenser fan motors still runs ok. I put my fingers on the low side line ( from evaporator core to compressor), feel no cold. I think it is low Freon in the system. I verified the pressure gauge readings before recover the Freon, High side....120psi, Low side..... 20psi at engine idle. Reclaim the Freon (engine stopped), found out the A/C machine just recovered only .04oz, like I say major leaks and worry over contaminated refrigerant (Freon)where the air/moisture entered into the system. I investigate the lines, condenser and compressor, found no sign of leaks (oil stained), then replace a new Schrader valve and evacuate about 30 minutes (very deep vacuum) to clear contaminated Freon, add about 1/4 oz dye detection oil and recharge 1.21 lbs R134a Freon into the system. I touch the low side line with my one finger to feel the line..... Very cold,observe the pressure readings ... High side 255 psi / Low side 45psi at idle and outside temp about 90 degree F. I insert my thermometer into the vent (center of the dashboard), the reading shows 42 degree F at idle and 38 degree F at cruise. Real cold air and make me happy mechanic. I remember I did serviced A/C system in last 5 years ago.
The cost of A/C service, Freon and dyed oil or labor is $ zero $$$$
We normal charge customers $49.95 for A/C service (not include freon) and $ 85 dollars per one Freon pound. Expensive?????
