"I had previously gotten a quote from *****busters that was 3x the amount that AIT quoted. I felt better about going with AIT though because of the service - Artur and his team were confident in their service and the products they sell and they guaranteed that they would stand by me until my home networking issues were resolved. Months later, my entire 4500 sqft home receives flawlessly smooth internet/streaming without anymore blank spots. I cannot recommend AIT enough to those looking for affordable and quality residential networking diagnosis/installation."

Landline Phone Service questions, answered by experts

As long as your landline is corded, meaning your telephone has a handset wired to a base unit on the wall, it will work during a power outage. Cordless phones won’t work without power, and cell phones will run out of battery eventually, so having a corded landline can be vital if your area loses power frequently or for long periods.

Costs depend on panel size, labor, permits, wiring materials, and required safety features.

For the average home office, you should only need one line. It’s uncommon to need more than one business line for a small or starting business. The exception is for the hard workers who manage multiple businesses out of their home and want a separate line for each to keep everything separate. In that case, it’s relatively easy to add another line with VoIP, but significantly more expensive for an analog/hardwired phone system.

While homeowners can make basic repairs with the right tools and knowledge, professional assistance is advisable for complex installations to ensure proper functionality.

Yes, many repair services include upgrading outdated systems with modern features.
