"This company is absolutely fantastic! Tony is so professional and a really great guy. He bid me a price for some work that turned out to be much more complicated than originally thought. He did not try and increase his price and did the work for the pre-determined rate. In addition, I had a tv he was supposed to hang that was brand new in the box. When he opened it, he discovered the screen was shattered. I was able to return the tv and he is coming back out on a separate trip to hang it. He has really gone above and beyond. I cannot recommend him more highly."

"Mike was able to assess the needs of the job using text messages and photos sent from my phone. He arrived on time on the day of the job and observed proper coronavirus precautions and wore a mask while in my home. The new TV was a difficult install that the Geek Squad couldn't handle. Mike was able to construct a new mount out of sight within the cabinet which would allow the screen to fit flush with the frame and yet easy to manipulate so the cables could be accessed. When completed, everything looked neat and professional."

"I was on the market for a security system and this one seemed easy enough to install.......went through the process and some of the window sensors were not working. I called Customer Support who was very friendly and we went through the entire process again...this time other window sensors did not work. This went on for a week or so...then the door senors stopped working....than the motion sensor stopped working...at no time in over a month did I have a fully operational security system. As I was about to return the system I was told they have "new" sensors and they just realized they received a bad batch and are working with another company.....Gave it a try....and same issue returned....some sensors worked....some didn't. I finally returned the system and stopped getting emails.....only to find that they were still billing my credit card even after I returned the equipment. Very nice people and very understanding.....unfortunately their product is not up to par. While we do have a large home, it's an open concept and the sensors that weren't working were no more than 15ft away from the base. The previous owners of my house had a wireless system with no issues at all.....I'm going to be using that company going forward."

So go ahead, start enjoying your new life style, knowing answers to all your questions are only a call or an e-mail away. And the best part is all of our services come with a 30-day, risk-free trial.

"The Smart Home features they installed, such as thermostat and door locks, etc. do not always work. For example, the Honeywell thermostat can no longer be operated from our phones and is difficult to install. Remote door locks are also unpredictable."

Home Automation questions, answered by experts

Options include wired, wireless, and smart systems with features like cameras, motion sensors, and remote monitoring.

Smart switches work with pretty much any light. However, if you plan on using a dimming feature on your smart switch, any LED bulbs you use need to be the dimmable kind. It’s more the wiring of your existing lights that can be a problem. Some smart light switches need a neutral wire, and old houses (built before 1985) don’t always have these. Always check if the model you want needs neutral wiring to operate. 

You should always install cameras at exterior doors and windows. Other areas where you should place cameras are your front and back yards, the garage and driveway, common living areas, hallways and staircases, and the basement. Remember, you can start with a small Wi-Fi security camera system and always add more cameras if needed.

If you don’t want the hassle of installing smart light switches, you might consider replacing all your bulbs with smart ones. Simply screw in the smart bulb and download the app to allow you to switch the lights on and off remotely. You can even change the bulb color to create a certain ambience in a room. However, these LED bulbs are pretty pricey, especially if you already have specialty light fixtures, and you won’t have to just replace them once like you will with the switches. 

Smart switches require a neutral wire for correct installation. Neutral wires aren't typically present in a single-pole switch configuration, so this project can be a tricky one for average DIYers. In most cases, you should hire an electrician to run a new circuit or adapt your existing wiring to include a neutral connection to accommodate a smart switch.
