Cornerstone Pros

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. William Messina DNP, RN

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.

Excellent service and really quick response time.(Under 3 hours)

Great guys who explained what they were doing and what we could do going forward. Happy to give other advice and no hard sell of service.

Would recommend highly

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

Overcharged me for service and I believe they are being dishonest regarding the charges. My air pump unit outside was making a loud noise which is less than 2 years old. Called Cornerstone and asked if they do warranty work which they said they did. Scheduled appointment. When they showed up, immediately the service guy determined I had a bad contactor which needed to be replaced. He told me at the time was $198.00 for the part and $69.00 for the service fee. Asked about the warranty and he advised that the unit is under warranty but the part would still cost $198.00. Even when these items are under warranty, he said you still have to pay to stock it back with the company and that $198.00 was my warranty price. I went ahead with the service but thought I would follow up with Trane (which is the brand of my air conditioning unit) to confirm later. The next day Tiffany from Cornerstone called to ask about my service which I advised that the service was good but couldn't understand the price since it should have been covered under warranty. She said she would check into it and call me back. When she called me back, she said that it was a wear and tear item and that is why it wouldn't be covered under warranty. A few days later, I called Trane, they said that the part was covered under warranty that a warranty was not submitted for my part and that other than labor, I shouldn't have to pay for anything. Called Cornerstone back and advised what Trane said who they advised again that they would look into it and call me back. When they called back, they admitted that the part was covered under warranty but what the cost was for labor. $69.00 was the initial diagnostics and $198.00 was for the labor of replacing the part. I told them that this was an outrageous price for labor. The service guy was here for about 15 minutes replacing the part and 10 minutes talking with me. Even when you look at the bill that I have, it shows $69.00 for diagnostic and $198.00 for the Contactor. If this be the case, they are charging about $534.00 an hour for labor.

Totally incompetent,called on 8/4 for an A/C service,my appointment was for today8/5 between 8am and 12pm( no show),I call at 1pm to check on arrival time,they have no record of me making appointment,claim they have no service tech named Alan(which was given to me when I made appt.)working there,now they say they're two weeks out on service calls and no one there would have made my appointment.I guess I made it up,I will never call this company again,I'll fix it myself first.Do yourself a favor and avoid a headache,don't use them.I gave them a one,only because Yelp wouldn't post without.

They are a fantastic, locally owned business. Their technicians are professional and take the time to answer all your questions. Matt was at our house until 11 pm helping us determine the best unit to choose after a lightning strike. You cannot go wrong with this business!

I called Cornerstone based on the reviews on yelp.
I had a ac balancing issue I needed help with.
The first two people I spoke with all said the company could help fix the air balancing issue and went into details as to how they would address the issue.
I then set up an appointment with the scheduler and then reconfirmed what the tech would do on the service visit. After being put on hold for a few minutes, I was then told they did not do air rebalancing for new customers. Wasted 20 minutes of my time.

Called to get a quote said they could not. Told them I had another company come out but was discouraged when their machine broke and they were indifferent when I said ok I guess I will just go with your competitor. Very snarky. Angie was her name.
