Cornerstone Pros

I had a coupon with tune up for $39 value (1 lbs freon free included if freon was low). When he comes up, freon was low and there was chance of leak. So he made it service call as it was low in freon and AC was not working well according to him, and further the leak detection was chargeable to $198 + freon (chargeable for all)+ fixing it (unknown price).
Now coupn says ""if low on freon"" in AC tune up and technician says ""service call"" if low in freon and then makes it a leak detection. So 3 star. As it seems complicated to me.

Tune up means clean up drain lines, check for any leak and that all parts of AC are working fine. But only got freon checked in service call/ tune up but paid for all as coupn was waste.
We just got freon added and AC is running well.

I m not prepared to pay for leak detection and fixing as AC was checked 6 months back by AAA airwaves and 2 lbs freon was added too (Sept.) when they came to see AC stopped (coz of ice). So 99% chances last company cheated on us. I have had experience with 3 companies so far and just end paying much more everytime and worst part is AC is 2014 built. I need recommendation on right AC company.

Not sure a jack of all trades can be the master of your issue. Had him out to evaluate the AC over summer of 2016 as I wanted to replace it. While measuring voltage, he blew the transformer that supplies power to the interior thermostat. BIG shower of sparks, except July 4th was last week. Then started denying it. Said he had to go to the shop get another (10:1 stepping xfmer and AC guy does not have one?) and left.
I probably should have complained, but the next guy I had came in far more competitive than any of the other 4 and had also done my mom's home, so I just moved on. He also replaced the transformer for no cost.
Perhaps their other techs are better, but don't deny issues to someone who is familiar with HVAC.

TERRIBLE company. The last 2 times that they've come out for our ""scheduled maintenance"" that came with our service plan, our a/c has stopped working properly IMMEDIATELY after they leave. This time, the technician told us that because we've had work done by another company (an honest family friend who doesn't charge SO much) they wouldn't be able to honor a warranty on parts (not that I expected them to...) but our a/c stopped blowing cold air as soon as he left. My husband called to tell them that our a/c stopped working directly following the maintenance call and she said that the technician would come back out, but if it was determined that the malfunction was due to the previous company's work then they would have to charge us a service fee. ARE YOU SERIOUS????? Your technician left my house an hour and a half ago!! Clearly it was because of something he did. Such a lousy dishonest company. Whether I have to pay the service fee or not I will not even bother with the rest of our service agreement. I'm NEVER doing business with this company again.

I'm in the process of buying a home and just had a home inspection performed. The inspector pointed out a couple of issues that should be repaired by professionals. The exposed copper wiring in the electrical panel had blue and purple discoloration, and using an infrared camera, he detected moisture buildup in the wall between the master bath tub and kitchen.

I reached out to Cornerstone for a couple of repair quotes, since they had good reviews and their site advertises that quotes are free, so I could try to negotiate the sale price on the home. After submitting the details on their website, I was called less than 15 minutes later to be informed that technicians would have to go onsite to inspect before giving me quotes for my requests, but that they would give me the reduced rate of $39 for each, rather than full price. Not quite free as advertised, but I agreed on that price thinking it was gonna save me some money on the house.

After scheduling the appointments for 2 technicians, I wasn't able to get my schedule cleared to be onsite while they were there. Cornerstone told me I could provide them my CC to have on file, and as long as someone was present to let the technicians in, they could perform what was agreed to, call me to let me know what was recommended, and if their was anything to be done immediately, get my authorization to do so. I let them know the current home owner's renters would be present to let the technicians in, so all was set.

The electrician calls me and says he doesn't see any discoloration in the electrical panel wiring. I saw it for myself, and had the pictures in my inspection report.I told him my worry was about a possible fire hazard, because that's what the inspector told me to be wary of. He said there weren't any problems, so I thanked him and that was that. I never spoke with the plumber. He left me a voicemail stating he couldn't find the leak. Well of course not, it's behind the wall. And I didn't need it to be found yet, just a quote on what it could cost to find it and fix it, given the different things that could be causing it. I called him back, and left a message saying as much, but he never called me back.

So I've effectively paid $80 and have no quotes to show for it. I emailed Cornerstone, because I felt what I submitted on their web form, wasn't properly communicated to the technicians, especially the plumber, and I wasn't getting what I asked for, which should have been free in the first place. I provided the pictures from the inspection report to try to be as clear as possible. The following morning, I received 2 voice mails, one person asking for a call back, the other saying they would send another plumber back to the property. I call back, and neither person is available, so I explain to the new person on the phone, I don't need service performed, I need a potential repair quote to negotiate the sale price of the house. After being put on hold for a few minutes, I was finally given some $$$ figures to go along with several different scenarios, which is all I wanted in the first place. They typed it up and emailed it to me to provide to my agent.

But my experience gets worse from there. I had 2 charges show up on my credit card, as expected. One was for the agreed $39, the other was for $213!! I call Cornerstone back and ask for an explanation, since I was told $39 for each one. They tell me the plumber performed a visual inspection and this is how much it costs. Again, I was told $39 which is all I agreed to. Anything more than that, they were supposed to call me for authorization. They said they didn't know who authorized the extra charge, which made me irate because why would you accept an authorization and not know who gave it, especialy when it's not the person paying for it! They asked if I would like someone from management call me to discuss further, because they couldn't do anything about the charge at this point. Damn right I did! They were supposed to have a manager call me within 24 hours. 2 full business days have come and gone, no call.

Seems pretty clear to me this company uses false advertising, poor communication and plain dishonesty, to try and get money out of people.

My faucet in kitchen broke and I called Cornerstone. They came promptly. Tony was awesome and explained everything. He had such a friendly and funny attitude. He removed the old and replaced the new one in about an hour. He cleaned everything too. Could not ask for better service.

I am very happy with the work Cornerstone performed in replacing my heat pump. We replaced a 14 year old unit that was making a lot of noise. The new unit works great! They were on time and were very neat. The county inspector also told me they did a nice job.

Super responsive customer service. Pete was a big help with some older electrical equipment - knowledgeable and ingenious.

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
