I received quotes from three highly rated providers on Angie's List. One was Cosmos. I liked Cosmos b/c it is a small, family business and very close to my home. Each of the three quotes included a budget A/C system and the next step up in cost and efficiency. I decided to go w/the "up to SEER 16" system. Cosmos' quote was a few hundred dollars more but they agreed to match the price quoted for the exact same Carrier 24ACC6 system by a competitor. Cosmos' Gus and George (father and son) and a worker arrived on time. They swapped out the old system and installed the new one smoothly. They were careful of our home and cleaned up all of their mess. The new system is far superior to our old one. I would recommend COSMOS to others because Gus puts customer satisfaction before profit and is willing to bend over backwards to meet the very high expectations his Angie's List reputation engenders. Notes: 1. Walking by I noticed that the installed v-shaped coil had a number of bent heat transfer fins. It looked like a wrench had been dropped in it. The worker was near and I asked. He said, not to worry, that they would straighten them out; but then he attached the coil to air ducts without fixing them. I complained to Gus about this and another, possibly cosmetic, problem. Gus immediately said he would fix things to our satisfaction. He instructed his son, George, to remove an already installed piece to gain access to the coil so that the bent portions could be combed straight and he ordered a special flexible connector to address our other concern. 2. After all the work and clean up was done, I noticed that two largish holes in the sheet metal vent leading to the air handler had not been patched. I believe these holes were part of a humidity monitoring system that was removed with the old system. It was a simple matter for George get the supplies back out of his truck to patch the holes. 3. While Gus worked inside installing the coil, George was outside installing the compressor. When I went outside to look at it, I noticed that it overhung the pad on all sides. George ramarked that this 32x32 pad was the size recommended by Carrier. The AC was stable and it was aesthetically pleasing not to see the pad; however, I was accustomed to a larger pad to to help provide a buffer for the lawn mower. When I expressed this concern, Gus quickly dispatched George to fetch a 36x36 pad.
