$3,500 quote to replace 1 AC part, $450 an hour labor???

[Jack B.]

Quote I got from an AC company here. To replace a low pressure sensor that is under warranty. They want $500 an hour for labor. WTF??

To add insult to injury, every company I’ve asked for a quote based on the quote I got from the first vendor, wants me to pay another several hundred dollar service fee to come out and look at it themselves. They won’t give me just a quote for what it would cost for the same work in the first estimate.

Am I obligated to replace or repair the AC? It’s a luxury here.
