See What Our Clients Are Saying
We sent Kelly's AC an online appointment and an email on Sunday evening explaining our AC issues. We received a phone call at 8:30am Monday and they were at our home at 1:00PM. Our AC was repaired by 2:00PM. WHAT GREAT SERVICE! GREAT PRICE! Got us out of a Major Jam. We Love this Company, we highly recommend them and will definitely use them again. Thanks so much Kelly's AC and your AC Tech Eddie Costa was Great 🙂 Mick & Nikki Pasmore
