"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

"Joe and his team of electricians led by Paul were amazing to work with! Very professional, on-time, and fair pricing estimates for electrical work I needed in my condo, including moving the position of a ceiling light and setting up two new sconces, both of which required patching up the drywall afterwards and they made it look seamless. Joe really values quality work and made sure to check in throughout the job and afterwards to make sure I was satisfied, answering any questions I had.

You might like to know that you’re buying the right equipment and getting it at a fair price. **WE SPECIALIZE IN HOME STEREO AND THEATRE SYSTEMS**There's a proven way to do that - good planning. With 20 years professional experience I know what to ask you whether you’re an avid enthusiast or a novice. I know what to look for in your home (i.e. infrastructure). And, we talk. After we're done planning, you've got one very solid solution. (And, this is what I love doing!) A manufacturer-authorized dealer, you pay no more for product bought through me than you would from a brick-and-mortar store. You benefit from my lack of overhead expense - mine is a home-office - by paying less for installation. You get my support after the sale so you don’t have to deal with frustrating tech-support lines. DH Audio and Home Theater offers wired and wireless speakers, TVs, home theaters, acoustic room treatments, equipment cabinets, and Wifi-Network systems.

"Dennis was super helpful, personable and professional! He called me immediately upon receiving the quote, and was communicative throughout the lead-up to our appointment. He was friendly and quick (and early) - he set up my turntable and speakers quickly and made sure I knew how to use before he left. Would definitely recommend Dennis!"

Smoke Detector Installers questions, answered by experts

When deciding whether a home automation system is right for you, consider the advantages and disadvantages first.

Pros

  • Home automation can help make your home more energy efficient, possibly lowering utility bills.

  • A wide range of automated solutions is available to meet your needs.

  • Centralized and remote control of different home automation systems.

Cons

  • Home automation can be costly.

  • Not all automated systems are compatible with each other.

  • Over-dependence on home automation can be problematic if systems cannot connect to the cloud.

There are ample home security options available today outside of just window bars. Depending on your location, home’s layout, and needs, one or more types of home security systems may be necessary. You could consider doorbell cameras, motion-sensor flood lights, or window and door sensors. And in some cases, you may qualify for homeowners insurance discounts when you install one or more.

Security camera prices vary widely, with individual cameras typically ranging from $125 to $450 on average, not including professional installation costs. The camera's quality also impacts what you pay. Expect to pay more for desirable features, including a resolution of 1080p or higher, a field of view over 110 degrees, and enhanced night vision. Remember, your out-of-pocket installation cost will increase significantly when purchasing a complete system to cover your property inside and out.

Yes, evaluating needs based on home size, layout, and climate.

Your best bet is to install a bracket that secures to the bottom of the unit and the side of your house. You should still secure the AC unit in the open window using some of the other methods already listed, but a bracket is best to ensure that it stays put—both during operation and in case of an attempted theft.
