After having bad experiences with two previous certified Trane installers I was a bit worried about Custom Cooling. My fears were put to rest as soon as the tech came to the house. The technician I spoke with was very professional, knowledgeable, and took the time to answer all my questions.
I had the unit on my rental property replaced within a couple weeks of the initial consult and couldn't be happier with the crew that did the install. After the install crew was finished the original tech I spoke with arrived and followed up on the install and verified everything was done properly.
It is extremely hard to find competent people today but Custom Cooling is the exception. The technician did not try and sell me things I didn't need and didn't push the highest end unit either (we discussed pro's and con's so I could make an informed decision but he actually recommended a middle of the road model for my situation). I mention this because the previous company I had servicing the Trane unit on my personal home spent more time trying to sell me duct cleaning and surge protectors than servicing my unit and when I pointed out a warranty item that needed repair he spent additional time trying to weasel out of covering under warranty.
