Well my A/C does not cool as well as it should at idle or very low rpms..when cruising the a/c works fine. I took it to an A/C Shop and the guy said the A/C has plenty of freon in it but he thinks that the Expansion valve is clogged and would need to be replaced. I have heard good things about this shop. He said he would replace it for 320.00.
Does this sound like the right diagnosis? Does it seem like a fair price? Is it something I could do myself? I went to autozone and priced the part, 34.99.
Considering how much of the dash you'd have to tear apart and then have to refil the AC system with freon if you DIY, that really isn't too bad. I'd rather rebuild the engine then tear the dash apart.
I used to feel the same way until I pulled the dash on my Civic. I had to replace the entire evaporator in my car because the thermostat went bad, and replacing just the thermostat would have been harder than replacing the whole core.
Now I've had the dash in and out of my Civic a few times. Only a few wires to unplug, 6 bolts, and drop the steering column.
If you don't have the equipment to properly recharge your AC system though, i think $300 or so is a fine price to pay someone to do all the work.
