Showed up to my condo in the Phoenix area on Sunday morning to find my inside temperature to be 94 degrees. I had to open the doors, because the outside air was cooler than the inside air. It was Sunday, and I called and left messages for three different heating & air conditioning companies. Day & Night returned my call and I talked with Liz. She was compassionate and gave me several options. Since we were traveling to the Grand Canyon that afternoon, we opted to get the unit repaired on Tuesday when we returned. The team for Day & Night arrived at the appointed time, diagnosed the problem and gave me several options. (still haven't received return calls from the other companies that I contacted) Ricky and Alex were terrific; nice and respectful gentlemen and very knowledgeable about their work. They were also very professional. Some reviews have stated that their prices are high. I say, you get what you pay for. With Day & Night, we received quality service and "peace of mind".
