Hector D.

Found Katz at the upland farmers. Needed a couple of house keys copied, josh was friendly and helpful with our copies. Now they will be my go to if I lock myself out of the house!

Amy D.

Our house on Euclid Avenue in Upland was built in 1914, and the antique mortise lock on the front door was no longer operational. We called Katz, and Athena came out the very same day. After disassembling the lock and cleaning all of its internal pieces, Athena was able to figure out what was causing the problem - one of the parts had a section that had worn down over time. Because replacement parts are next to impossible to find, Athena was able to use a small piece of metal to craft a new piece that rectified the issues caused by the old, worn piece. It took a lot of trial and error, but Athena persisted until the lock was reassembled and working perfectly. The charge for this two-and-a-half hour house call was very fair. I am totally impressed and highly recommend this business.

Amazing with the kiddos. Thanks for everything.

The kiddos had an amazing time making keychains. Thanks for being so great with the kids.

See all

I contacted Ricardo after checking out his reviews, he responded quickly and we easily set up an appointment. He discussed possible options of placement of the ports since the roof and outer walling might pose an issue, but he was able to find good placement of my ports. Job was done quick and easy in less than 2 hours. Aside from making a hole in the wall for the ethernet port placement, no additional breakage of the wall was necessary. Ricardo did say that in some cases, depending on the walling and roofs, breakage of the wall would be necessary for some people, but not mine fortunately. Ricardo and is colleague were awesome, professional yet friendly and personable. They cleaned up after themselves and did an overall fantastic job to make any streaks or scrapes anywhere. HIGHLY recommended if you are looking to have ethernet ports installed that extend from your main router/modem that go through the wall/roof so you don't have ethernet cords lying around on the floor.

Carlos also walked me through how to use the system as well as make adjustments to each camera to my liking. Top notch service. I received other estimates from other companies but Security Eco was by far the quickest to respond with answers to all my questions along with the cost of everything, which was extremely competitive. For the service provided, the value is incredible and I will be using Security Eco for all my security needs. Highly Recommend.

I had no issues with the alarm service itself. But I do have major issues with shady business…read morepractices. I do realize that ADT corporate is different from installers like DPS and my complaint is more with corporate, but I feel it is my duty to inform potential DPS customers what it is like to work with ADT. DPS did my initial install and while they have been professional and courteous, they are attached to a deceitful company. Last fall, I decided to sell my house. I wanted to upgrade my control panel to an all-digital panel as part of sprucing up the house for sale. A tech came out to check out my equipment. He quoted me a price for the new panel and came out the next day to install it. I have now moved and called ADT to cancel my service. I was informed that when I upgraded my control panel, I signed a 2 year contract. Well, I was not informed of this by the tech. Did I read the purchase document for the panel? No. I'm admitting fault on that - but I was told it was just for the panel. Again, I told ADT (both in my initial reach out and in person with the tech) that I was doing this to upgrade for a MOVE. I made it clear I was LEAVING. Why on earth would I agree to a 2-year contract extension? After more than an hour on the phone with ADT trying to get it canceled (I was transferred 5 times) I was told I got the penalty reduced to "$22/month for 12 months." Before I signed (as I was in a hurry as I was at work and had already spent more than hour trying to get a simple contract canceled), I asked the account manager if there were any other hidden fees associated with the contract. He said no. Imagine my surprise the next day when a self-install unit arrived at my door with a pricetag posted to my account for ~$400. Once again, the account manager knew I was living with family and did not want or need an alarm. I do believe I was intentionally set up twice - and fell for it. That is on me. It's on ADT that I was set up. Nefarious business practices. I reported this to the BBB and a day or so later, I got an offer from ADT to reduce my penalty by $500. (The penalty was originaly showing as $1,300.) So now it's down to $700 but I am not giving up on principle. I was a customer for more than 8 years. I paid every bill on time every month. When I buy my new home, you can bet for certain it will NOT be with ADT.
