Excellent product and knowledgeable staff!!! I called the number from their website http://www.macxair.com and purchased an (remanufactured) AC Compressor for my 02 Acura RSX. The sales men recommended that I have the system flushed and the compressor professionally installed, well since I have an ac vacuum borrowed from my friend to flush the system, I didn’t, which could void the warranty. After installation and added freon the compressor did not engaged. After much frustration I called Millennium AC Xperts and asked what could be wrong. Voila! I added too much freon and almost screw up the whole ac system! Luckily after relieving some freon, everything worked.
