My fiance and I have used the Team at Day Advanced Air for several years and they are always fast to respond, honest and practical with repairs. Last year we had one of our units fail in the middle of summer, after going through 5 (YES I SAID 5) Different AC companies that were on our home Warranty companies list with each one either never answering the phone or saying they are a month out of just never showing up, we called DAY Advanced Air and they were out quickly and got us up and running asap. Even though I paid cash out of pocket, IT was well worth it to go back to a company that took care of us instead of never even getting return calls from all the ones my Warranty company worked with . I have now switched to a better warranty company and made sure they work with DAY since I do not want anyone else working on our AC and heating systems.
