Testimonials

"Excellent and honest service! I waited 6 hours for another company to come look at my A/C and they never showed up. Cornerstone A/C was able to come sooner even though I called them later. He was able to replace the part needed and get my A/C running in under 30 mins! Very reasonable prices. My only regret is not calling them first!"
