They are an outstanding company with outstanding employees. We use them for AC, electrical and plumbing. They are up front and honest with you. I have had interactions with at least 10 employees over the years and all friendly and knowledgeable. We were having our semi annual AC checkup and the tech notice high voltage coming in so we an electrician come in to validate. After that one phone call got Duke energy to correct it. Probably has saved equipment in our house. I would recommend them for any of there services.
Chris J. is a very honest plumber with Cornerstone Pros. He is always able to explain the problem/solution to me in very easy to understand terms. Chris is very reliable and friendly. I always request him when I have a plumbing need.
The service was absolutely impeccable. The whole staff from scheduling to the on-site crew was incredible. Due to Hurricane Irma, I had to reschedule and the staff stayed in contact with me after the storm working off their personal phones to keep in touch with me to find out when I had powered restored. Once power was restored they immediately got me on the schedule and sent Daniel & Ray for the 2 day project. Daniel & Ray were diligent, professional and steadily worked safely upstairs and on the roof top. After completing the install of the mini-split they did a second walk down of the duct work repair they were returning for the second day. Daniel and Ray were very thorough and made sure they knew exactly what they would need to complete the project. They arrived on the second day for the duct work repair with all the correct equipment and completed the work in timely manner while cleaning up and not leaving a debris or dust behind. I was so happy with the work I spoke with another family member and about the service I received and my Grandmother signed up with Cornrstone on the gold plan and will be receiving service on Wednesday 9/20. Great company, great employees. The owners should be very proud of their employees and how they portray the Cornerstone brand. Thank you Cornerstone!
It went very well. Larry and his assistant, John, did a superb job of the removal on two systems and replacement with two new ones. Larry is probably the most highly qualified technician that I have every worked with. He is the go to person for a/c installation problems. He is ably assisted by John who is himself a professional. They overcame several obstacles to complete the jobs and both homes systems are working as they are supposed to – and that is very well. You cannot go wrong with Cornerstone Pros. I have been a customer for some 10 or 12 years and I have always gotten top notch service. I would not call anyone else for an a/c problem. I have not used them yet for their plumbing or electrical services, but will not hesitate to call them when I have a problem with either one.
Replacing my existing hot tub so I needed to contract my own electrician to hook up the new one. You would think that would be an easy, quick assignment… but no… not with the current massive ‘building boom’ going on in my area. After making several inquiries and asking friends for advice I was starting to get concerned that I wouldn’t be hooked up for weeks and possibly months after speaking with several local business and companies. Thank GOD for Cornerstone Pros! They were the only company I could find in the area that actually answered my call and actually scheduled an appointment for me in 5 days instead of 5 weeks ! So Impressed with the workman (Pete) that Cornerstone Pro sent out to do my electrical project. Again, It was so difficult to find a professional in my area that was licenced, willing to do small electrical jobs that could schedule a visit within days. Pete, showed up at my house on time as promised, was so easy to communicate with, understood exactly what needed to be done, suggested improvements, explained the need of everything being within code, secured everything, double checked circuits/box for wear and tear (old house), ran the spa for several minutes making sure the unit was shipped properly and made sure I knew how to operate it before leaving ~ All this in this sweltering July-end Florida Heat at noontime! I rarely write reviews,I needed to write this today since It has been a very long time since I have seen such excellent service from a business, in the mist of such high demand for huge contracts and projects still look out and take care of residential business too ! Keep this company’s name and number in your address file. Ask for Technician Pete if possible… You will be glad you did!
We had a FANTASTIC experience with Cornerstone! We had a 14 year old unit, that by the looks of it had never been serviced in its life! Needless to say it was time for a new one. We first dealt with Chris who was great; even answered all my dumb questions because let’s face it who really knows anything about AC units (definitely not me). When it was time for install we had TJ and Mike come out as well as two other gentlemen. Not only did they install a great system and clean the ducts, but they also put down a new concrete slab, painted inside the air handler closet, cleaned up after themselves and much more. I especially liked that I was emailed every time someone new was coming to my home so I knew exactly who to expect. Oh and there customer service is incredible! I called on Saturday to the emergency service because our AC unit decided to die that day and was called immediately back and was scheduled for our install within hours. I will be using them again for sure!!! Thanks Cornerstone!!!
Thank you to both Brandon B and Scott for taking care of me this weekend. They were very knowledgeable & friendly. I have been a loyal customer since 2011 and the entire team from the front office to the service technicians have always been great! Great Job everyone! Thank you!
CORNERSTONE SOLD ME THE UNIT LAST YEAR AND THIS WAS THEIR YEARLY CHECK UP, SO FAR SERVICE INSTALLATION AND MAINTENANCE HAS BEEN GREAT. THE TECHS. ARE VERY PLEASANT, WELL MANNERED AND RESPECT YOUR HOME WITH BOOTIES WHICH I SINCERELY APPRECIATED. MATT F. WAS THE MAINTENANCE TECH THAT CAME TODAY AND HE WAS EXCELLENT,VERY EFFICIENT AND KNOWLEDGEABLE. THE OFFICE PERSONNEL ARE ALWAYS GREAT AND HELPFUL. THE EMPLOYEES CALL AHEAD WHEN THEIR COMING AND HAVE ALWAYS BEEN ON TIME IF NOT EARLY. GREAT JOB, A WELL OILED COMPANY THAT WILL BE AROUND FOR A LONG TIME TREATING CUSTOMERS THE WAY THEY DO.
The Daikin AC unit has outstanding features and is a quality product. Your installation crew did an outstanding job complering the installation in a timely and professional manner taking time to outline all the features. The product and support team are a great credit to you company. Thanks we are very impressed.
I have been using Cornerstone for a couple of years now. I started off on my primary house with plumber Kiel installing a iron/water filtration for iron in my well. I then had an electrician install additional outlets at my home and a hvac agent service my a/c system. I was talked into buying the service plan by Kiel and I’m so happy I did. I am getting quality work at a discount. Today I have my dad’s rental property getting flipped, because well,it needs to and he can’t do it anymore due to dementia. I hired some contractors to fix up the property (redo floors, tile work, and even install cabinets). One contractor even claimed to be a prior plumber and assured me he could conquer the job with quality. Well…thank goodness Jerry, a Cornerstone plumber, came to my rescue because my so called plumber had no clue what he is doing. Jerry is taking the time to make sure the plumbing is done right and to county code! Going above and beyond the call of duty. Every time I have called cornerstone for electric, plumbing, or HVAC it has always been top notch service. I know you may not be the cheapest, but you definitely get what you pay for! Thank you!
