Our a/c system stopped working and it turned out that we needed to replace the whole system. The technician, Michael, arrived at 7:30pm on a Friday night and quickly diagnosed the problem. He got the system working so we could be comfortable until the following week. The installers were careful not to damage our wood floors and left us with a working system. There is no such thing as an inexpensive and good a/c system, so we feel we got good value for the money.
