These guys are jerks.
I bought a replacement compressor pressure switch from them which malfunctioned after 3 weeks.
I called them and they wanted to send their technician out and charge me for traveling from City of Industry to Ventura, a 2 hour drive, to check it out before they would replace it. Or I could mail it back to them and they will send it to the manufacturer and they would decide if it was my fault, thats a laugh, what a lousy company.
They said it must have been installed improperly. We had a professional compressor service install it.
Anyway, we called the compressor service back to check it out and they concurred that it was a bad switch and replaced it at my expense.
I only gave one star because the review software wouldnt let me give a no star review.
Dont use these jerks.
