Taylor understood the problem quickly and went to work. The clogged drain was cleared and clean in about 45 minutes. Cornerstone responded with next day service. Not a current customer at this time, but in the future will consider becoming one.

I had to replace some water lines in my laundry room. I called Cornerstone. I have used this company once before to replace a sink and toilet in my bathroom. They did excellent work this time as they did last time. I was given a fair price and the work was top notch. I wanted to thank Alex and Raul for the great work they did on site. I will continue to use Cornerstone for any future projects they are able to help with. Keep up the good work !! I have a bathroom remodel coming up soon and I will call you then !! Thanks Cornerstone Thanks Angie !!

We bought our AC unit from Cornerstone back in 2015 and took the 12 year parts and labor warranty. We have been having them come service our unit and have been doing service with them since then, and they are a very fair and easy company to work with. We will continue to work with them when it comes time to replace our AC unit again. Our Air Handler blower motor conked out, and they were able to send someone to look at it the same night, and then get us back to AC in less than 48 hours. We were charged a 69.00 service call, but that was a reasonable expense.

Travis was very professional and thorough. He took the time to fully examine and tuneup my air conditioning unit. He located a couple areas of concern and explained with pictures. After I agreed to a repair, he completed it right away. I had complete confidence in him and the company. Cornerstone sent me an email with my scheduled appointment. Then the day before service, I was sent a reminder. On the day of service, I received a picture of my technician along with a brief bio. It was letting me know that he was on his way. He was on time and had a nice personality.
Response from Cornerstone Air, Heating, Plumbing & Electrical
"Thank you for taking the time to share this wonderful review! We love nothing more than receiving five stars for our team's service, and we're so glad that Travis' expertise and professionalism earned your trust in him and our company. It's also great that our scheduling process and updates made your experience seamless. Should the need arise, we're always on call for you - stay comfortable, and thank you for choosing Cornerstone Pros!"
