Cornerstone Pros

Tom P.

I've been managing about 30 rentals for over 25 years, and have always found it worthwhile to maintain a win-win relationship with vendors. Cornerstone seemed like a respectable outfit, based on reviews on Angie's list, so I started dealing with them exclusively in 2013, joining their service club, and purchasing two brand new Heating/A.C. units, a Lennox and a Daikin. I found their technicians to be consistently pleasant and knowledgeable. Unfortunately, due to a sequence of three unrelated mistakes on their part, we came home to a ruinous flood in March, 2016. Cornerstone was very prompt in bringing in a competent remediation company (although this was extremely disruptive at a very bad time for my family). The real problem involved the ruined hardwood floor. Because this particular product is no longer available, we accepted the closest match offered. Though it has since proven unsatisfactory, we did agree to it and thus accept that responsibility. Over the next seven months Cornerstone sent numerous contractors to repair and paint walls, and to replace flooring and trim. Each of these repairs involved additional disruption. There are several remaining areas of damage, but we have not brought it up, preferring to avoid further disruption. There were several stages in this process where I had to call Cornerstone to get the next task accomplished. I was never abusive, but always polite, as a matter of principle. In October I received a letter politely informing me that Cornerstone was firing me! There is no signature, no apology for the misery inflicted upon us, just the implication that I have been unreasonable. Furthermore, the company suggested as replacement is not even a Daikin authorized distributor! I've been around long enough to realize that stuff happens, mistakes will occur, etc. (though these three are bordering on incompetence). But it is just such situations which reveal the true character of the parties.

Cornerstone charged me $439 to replace a thermostat on a 2 year old system belonging to a rental property of mine. I would not say the level of service was any better than other companies enough to justify such an astronomical price GOUGE

Dont waste your time or money. They dont care about your schedule or appointment. On top of that you get an incomplete and bad job done.

DO NOT USE Cornerstone air. They are a dishonest company/ manager and owner included, with incompetent, unskilled service techs. I bought a brand new a/c unit from them- very expensive. I also purchased a service contract with them to maintenance the unit. They sold be a unit that has had multiple problems. They have been unsuccessful with repairing the unit. They have avoided all of my calls refusing to come out to do warranty work and let me use my service contract. They have admitted that the unit is faulty and want to wipe their hands clean of it. They left me with a big mess of water stained and mold covered ceilings and a mess of an mold and water filled attic. In addition, they have dishonest repairman. On one appointment that I had with them, the tech asked me if I had any other problems in the house and I did have a problem with my dryer vent. They Cornerstone tech sold me that they repair a/c, plumbing, and electrical, and he would gladly repair my dryer vent. He did the job and he said his credit card swiper wasn't working so I had to pay him my cash or check. I wrote him a check and he said that he would bring it to Cornerstone and write up a invoice and mail it to me. The work he did was faulty so I called Cornerstone to ask them to come to look at it. The manager/owner of Cornerstone air said that he knew nothing of this repair and refused to take responsibility for his employee. He told me that the company was not responsible for their employees doing this type of work. I have been trying to get them to come out for nearly a year now to come out and paint the ceiling that was supposed to be covered under the manufacturers warranty due to a faulty unit. I have also been calling them to have a service man come out to service my unit because I have water and mold all over my ceiling right below the a/c unit. They have avoided my calls and just finally told me today that they didn't want to service my unit anymore because there have been too many problems with it. They recommended that I find a different a/c company. Cornerstone is fantastic about taking your money to purchase and install a new a/c unit and sell you a maintenance contract but are incompetent and unwilling to make good on a faulty unit that is still under warranty and that they sold you a service contract for. Cornerstone has been nothing but a VERY EXPENSIVE, time consuming, home damaging headache for me. I HIGHLY suggest not engaging in business with them.

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!

Excellent A/C service however way expensive on Blue Light UV purchase and install. I paid $594 for install of a 2 year Fresh-Aire Blue Tube TUV-BTER 24 Volt UV Light. Amazon sells the same exact item for $278. Install took less than 15 minutes ($316 profit... is excessive.) I should have investigated this further before purchase; so as the saying goes """"buyer beware!"""". It a shame too since I am one of their long time Platinum Customers.

Every time I see one of their billboards advertising """"Call Today, Fixed Today"""" I just chuckle to myself...I last contacted them about 2-3 months ago to service a unit purchased from them (along with a full 10 year parts and labor warranty) only three years earlier (that has had CONTINUOUS issues); they showed up on day one to diagnose the issue, and then disappeared for over a week with NO communication whatsoever. My tenant called me on the 7th day of having no working A/C to ask for an update...all the while I believed the issue had been resolved. I called them to find out what was going on, and it sounded as though it was not a priority (perhaps they were aware, yet didn't bother to communicate this to me). I was a loyal customer of Cornerstone for about ten years, but I firmly believe they've outgrown their ability to provide the service they guarantee, and their prices have gotten *ridiculous in comparison to competitors. They try to sell you one of their annual maintenance plans with each visit (with a convenient monthly payment plan). I ended up buying it on several occasions for my personal residence, which amounted to two free annual tune-ups and discounts on repairs, all for about $150.00 annually. I would have paid less for two tune-ups elsewhere, and the """"discounts"""" I received only brought their pricing a little closer to what I discovered I would pay with a competitor. This unit was also purchased from them with a 10 year parts warranty. The two times I needed warranty repairs, the labor cost was more than $500 for less then two hours of work (the service tech stated that Cornerstone charges flat fees for every job rather than hourly rate pricing)...only after complaining about the cost was I offered an additional discount and removal of the service call fee (which became the norm...there was always an 'initial price quote' followed by a 'better price quote' with a discount reserved for some plan for which I was not currently subscribed). I will say that the techs were always polite and friendly, but always trying to sell some additional plan or protection. I am done with this kind of service. I can't imagine treating customers like this unless you *want to lose business.

Thank you Cornerstone for coming out on a moments notice. Your technician got us up and running in no time.
