This was our first time to use Performance Air Conditioning, Electric & Plumbing. We live in Delaware, and when we came to our home here, the heat was not working. And, it was a cold night. We were referred to Performance by a neighbor, and we expected them to come out the next day. But, they showed up the same day, even though it was late in the day. The gentleman helped us get everything up and running, and stayed with us to make sure things were working right. We were so thankful for the prompt, and excellent service! They were just so quick and helpful! We have already recommended Performance Air Conditioning, Electric & Plumbing to other people, and we highly recommend them!
