    1.0 Emily D. Land O Lakes, FL

    Had the AC unit less than a year, had our free check up on Thursday. Friday our house was up to 82 degrees and had to wait hours for a tech to come out to fix on Sat. what was obviously an issue from the check up. The new tech advised 7 POUNDS of Freeon needed to be added. It is Monday and our house has gone back up to 82 degrees and is slowly rising from the Florida heat. Cornerstone advised no one can come out til tomorrow to fix a problem they caused and did not fix. I have now had to get a hotel for my one year old and husband so my sons fever does not increase from the heat and my electric bill over the past days has increased as the unit has tried to keep up but is unable to do so. I was told a manager would be calling me tonight (Monday), however after a call back I found out no manager is on until tomorrow..... I find this odd for a "24/7" company.

    My daughter who is a Nurse Practitioner working in the emergency department of Tampa General hospital during COVID 12 to 14 hours per day, had a Westinghouse water softner system installed by EXCEL WATER SYSTEMS!!! They incorrectly installed the unit and the unit was defective. Unfortunately, the system NEVER WORKED. We tried getting them to fix or replace the system and they refused. In fact they sent a representative to my daughters house who blatantly lied to her about the system and testing the water quality. Being frustrated and very upset we contacted the manufacturer and we were referred to Conerstone. We called CORNERSTONE and we were treated with the utmost professionalism, consideration, respect and FIRST CLASS ATTENTION!!! I personally want to give praise and thanks to Reese for EVERYTHING he did for us. Because of REESE I was compelled to make a lunch meeting to personally thank him and show my appreciation. If anyone needs any work done at their home or business YOU MUST CONTACT CORNERSTONE!!! I have never been more impressed by a service organization!!! Thank ALL the EMPLOYEES AT CORNERSTONE. I also want to thank Jennifer ( I believe that is her name) the operator who answered my call she went above and beyond for us and got Reese to call me!!!! You guys are THE BEST!!! Thank you

    We have used Cornerstone for years, mostly to nurse our severely aging a/c system, but also for the occasional electric or plumbing need. I love the integrity, quality, and professionalism of this company. The night we starting hearing our outside a/c unit INSIDE my kitchen, we immediately called. Although it was nearly 10pm on a Thursday, we spoke live with a tech, assured her that this was not an emergency, but we would like someone to come out asap. First thing the next morning, Cornerstone followed up with me and set an appointment for that very afternoon (Friday). They sent me both an email and picture of our tech and appointment confirmation. Prior to arrival, they called as well to ensure our availability. Our tech, Chris, was knowledgeable and respectful as he diagnosed the problem and presented different alternative solutions. We decided not to pour more money into a dated, failing system, and took the plunge to replace it. Chris provided us with various options, answered our questions, and gave us space to consider while outlining the next steps we would take once making our decision. He was extremely polite and professional. We reviewed our options, researched the offered products and prices, and found their quality to be superior and the investment to be a more than fair price for the quality. We completed the documentation agreement with our choices and contacted Cornerstone Pros to make the appointment. They forwarded me through to Chris again who was able to get the new system installed the very next day, despite it being a weekend (Saturday). I received another appointment confirmation email with the name and picture of my installer, Josh. Josh and his co-worker arrived at my house first thing Saturday morning. With 2 people working, the estimated installation time was cut in half, ensuring that our system would be fully functional by early afternoon. Both technicians were polite, respectful, and informative, explaining how to navigate through our new system, as well as ensuring the county permits would be issued once the business week reopened (I received my permit on Tuesday, along with a phone call to confirm) and the steps we would take to walk through that process. Cornerstone Pros is a company you can trust. They are deeply vested in this community, and their care for their clientele is evident. We are so happy with their customer service, quality, work, and professionalism, and we highly recommend them to everyone we know. We will continue to support gratefully this business as they strive to ensure that home is a haven. Thank you, Cornerstone Pros!

    Gary arrived on time so on time that he was 3-5 minutes early. We had already bought the faucet that we wanted replaced so all he had to do was swap them out. He worked fast and he was very good. The only negative is I thought was they were priced on the high end.

    Martin was excellent - competent, thorough, friendly and informative.

    On the initial interview their tech will tell you what you want to hear. at the installation they will do what they want!
