Had the AC conk out during the recent heat wave. Called Superior in the afternoon and by dinner time Tyler was at our place. He quickly diagnosed the problem and returned first thing the next morning with the necessary parts from the manufacturer and fixed the unit. Given the heat, the quick and efficient service was most appreciated. Highly recommend him and Superior.

Took a chance with them, they had my new A/C installed within 24 hours + two follow up visits within the next day to fix another problem at no charge. Excellent customer service. Technicians were wonderful. They were patient with me to complete payment. Thanks so much Superior!
