I went to them as a second opinion from my normal repair place. They quoted me a few hundred less and I went with them. A couple of days later, my entire A/C was replaced and worked perfectly. Later that day, my A/C made a weird noise, and they told me to bring it back. They came in early the next day (a Saturday) to install a new part (I guess they had gotten a bad one). They only had it a few hours and it was all done, blowing freezing cold air, and making no noise. Perfect! The employees were all courteous, knowledgeable, and helpful. They went above and beyond to make me happy. I will ALWAYS go there for any A/C issues in the future.
