We ordered air conditioning units for our home after suffering through weeks of extreme high temperatures. All Star came to our rescue and installed units appropriate for our house in a timely way, just before the next heat wave that reached 113 degrees in Santa Ynez. The units are so quiet we forget they are running unless we open the doors to the outside. The installers were very professional and nice to deal with. They explained how the units function so when they left we were confident in using them. We highly recommend All Star Heating and Air Conditioning and their representative Bob Lord, and installer Jesus.
