Having AC issues in the middle of a Phoenix summer is not pleasant. We were having issues with the AC for a month after moving into our new home. I called our normal AC guy but after three visits, he hadn't fixed our issues and I was started to take it out on my husband. I found D&N on Yelp, called that evening and had someone at my house the next morning. Willy did a great job and I couldn't be happier. AC is cold, it works, Willy was nice, professional, and thorough with his explanations. Thanks Day & Night!!!
