Cornerstone Pros

David R.

I have been relying on Cornerstone Pros for a year now and have never had a problem with them. They have installed a new A/C system last year and have addressed a plumbing and electrical issue recently. There is a pond in my back yard with a fountain that quit working. I thought it was an outside switch to the fountain but they determined there wasn't. The two service men were going to walk out into the water to try to determine the problem but I advised them not to. Despite telling me it would be another charge to come back later if they obtain a boat to check the fountain I told them to get the boat and come back rather than walk out into a muddy silt filled pond. Most recently I had an estimate on a stand by generator. Michael took time to explain everything and answered any questions I had. I recommend them for HVAC, electrical and plumbing problems.

They sold me an A/C unit at $5,000 that later I found out was being sold at just over $3,100 with other A/C companies. On a maintenance visit 2 years later the A/C coil of that same unit 'broke' for no apparent reason and they wanted to charge me an extra $1,000 for 'labor' even though it was covered under the warranty. I called another A/C repair company since I figured a 2 year old coil would not break down easily and the technician confirmed my suspicion that the A/C coil was tampered with and broken by external means by someone who knew how to break it without damaging other parts of the unit. Cornerstone Air Conditioning & Heating Inc. is extremely dishonest and criminal in their practice, they should be avoided at all cost. I will be following up with a complaint with the BBB and I want to advice to all of you to stay away from these criminals but don't take my word for it, you can call them up and roll the dice yourself, it will only cost you a good amount of your hard earned money to prove me wrong. That is if you think it is worth it to ignore this warning.

After our AC stopped working we researched companies and read reviews from Yelp. Cornerstone had received good reviews so we decided to give them a try. We were very pleased with the results!! We called this morning and received an arrival timeframe of between 10-2. We also got an hour call ahead to let us know they were on their way. Our technician, Richie, was very professional and had our problem fixed by 12:00 that afternoon. We will definitely be using Cornerstone again!!

Josh, the Cornerstone technician, performed the regular checkup and maintenance on our HVAC this morning. He was prompt, professional and very helpful. He even changed all five filters on the returns in our ten-foot ceilings for this 76-year old customer. I am completely satisfied with his work.

Outstanding professionalism. We 1st used them when one of our A/C units froze up on July 4th. They were prompt, offered a detailed breakdown of what the issue was, and what options to consider with the prices of each. We called them again when we had a clogged drain at Christmas (it always happens on the holidays!) when a manual snake wouldn't clear it. We had them come out on the 26th. They gave a time estimate, then called back to say they were running ahead of schedule and wanted to make sure it was OK to arrive early. Jerry was the tech who came out, and we were so impressed with them again on this 2nd visit we had them also look at replacing our aging hot water heater. Again we were given multiple options (with pricing) and invited to check around to see if it was a fair price. We did and it was. Despite it being what is in effect a holiday week between Christmas and New Year's the new water heater was installed in a custom location we had wanted, on budget in less that 48 hours after we gave the OK to do the work. Highly recommended for any plumbing, or A/C needs.

I used this company for an electrical issue I had. Manny arrived on time, he took all covid precautions & followed CDC guidelines. He explained to me everything he was doing. I was very impressed. Knowledgeable and friendly. A++ would recommend and will use again if ever needed.

Earlier today, I used Yelp's """"Request an Estimate"""" service in search of a plumber to clear a complicated backup in a multi-unit shared plumbing line. Mind you, it's Sunday, a busy holiday weekend, and a subtropical rain storm has literally just passed through. Daniel responded to my online inquiry and as soon as I called to provide him with additional information, he promptly dispatched Reese, who saved the day here in my condominium! Reese gave me a call when he was on his way and as soon as he arrived, he assessed the situation and worked so hard to help us clear this clog, keeping me apprised of his progress the entire time. He was conscientious about not dirtying my place, which I greatly appreciated, and he even provided me with his personal/professional opinion about preventing similar drain line backups in the future! Because of the awesome service I received tonight, I plan to tell my fellow board members about Cornerstone and I hope that we will do business with them again in the future (hopefully for a different reason though, ha!).

Cornerstone installed a Trane AC in my condo and left wires dangling in the AC closet and insulation half hanging. Had this been a low bid AC install, I suppose I could say I got what I paid for, however I paid $,5000 on this AC. I expected a better job. On the outside unit they poorly wrapped the insulation around the pipes that I had to go out and redo it myself. Needless to say when my other condo AC went out, I called """"WE CARE AIR CARE"""", not Cornerstone. Tim and his crew actually pulled a PERMIT and had his work inspected by the county after his AC installation; which is when I realized something was majorly wrong with Cornerstone. Cornerstone never pulled a permit, and if they had, this would never had passed! They promised to come back and fix it and they never have. Today I went to them to ask them to please come back and fix their work yet again, they want me to pay a SERVICE Charge plus a FEE to fix their poor work. I think I will write some good PR for them. If anyone wants to see pictures of their wonderful installation, please let me know, will be happy to post the pictures! I would never use this company again.

I called Cornerstone because they are a business in the vicinity where I live and I wanted to give them an opportunity to earn my business. The office person was very friendly and set up an appointment for a salesman to give me a second opinion on replacing my central air conditioning. Michael showed up on time the same day with a big smile and an eager to please attitude. He LISTENED to everything I said which to me is most important! By LISTENING, he was able to determine what my needs were and explained how his company could best meet my needs. I wound up making a purchase right then and there knowing I was getting a good deal and a good product. I would highly recommend giving Cornerstone the opportunity to earn your business and hope you have the same experience as I did.

After some issues with the 3 ton unit originally installed, Cornerstone swapped it out for a 4 ton unit at no charge. The new unit has been operating without issue! Yay!! Thanks Cornerstone!
