Wonderful experience with Lek, the owner, and his people. Great customer service, highly competitive price, and friendly and capable personnel who worked very hard and provided an excellent installation. They took great care and attention to make sure everything was done right from start to finish. For example, they made sure to confirm with me that the location of the new concrete condensor pad was just where I wanted it outside, that it was just the right height and level. They always took their shoes off before coming into the house and went to great lengths to make sure everything stayed neat and clean. Base contract was to install a new compressor and air handler, BUT, without any extra charge, they installed new and larger return air ductwork, new header collector box in the attic above the air handler and rerouted the attic ducts, new copper refriderant lines (25' long each), new condensate drain line (also 25' +) and new, color-screen, programmable Nexia/Trane. thermostat. The guys worked non-stop from early morning to late afternoon and Lek, the owner, personally came by TWICE to make sure everything was being done right and that I was satisfied with the work. He also took time to patiently show me the operation of the programmable thermostat and double check that I was satisfied with the work. I would recommmend Cool R Us to anyone and will recommend them to all my friends.
