"In May of 2023 I had a system installed. When hurricane Milton ? came through the system failed. Called for emergency repair. Was told for an upfront payment, a technician would arrive within 48 hours. Technician did not come. After repeated calls. I was told because of an over abundance of calls I was pushed back a week. Duke Energy restored power to our home before Genrex came by. Mind you the Generx is supposed to perform during emergency. Now to get a service for a annual check up, to maintain warranty. Was told my last service person used superior parts. Why would they not supply quality products initially? I am very unhappy with Generx. I will not recommend Generx. In fact I will strongly advocate against this company to family and friends. "

"The representative from Future Technologies stepped into my house and within 1 minute was able to identify and fix the problem that I had with my ring camera. In the past, I hired an electrician to hard wire the ring camera, but it never worked consistently. Even after 5 separate attempts to fix it, changing the transformers. However Future2000 Technologies fixed the problem!"

Electrical questions, answered by experts

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

They can vary—a lot. For example, while the EU continues to move toward broader standardization, many different types of outlets still exist from country to country. Some local standards cared about polarization, and some didn’t. It’s similar to other countries around the world.

Generally, you’re less likely to find polarized outlets outside North America. However, alternative plugs and outlets often incorporate precautions so that accidentally touching live prongs on a plug is hard or impossible. You may also find interesting regulations overseas that limit the use of outlets in bathrooms or near sinks to decrease the chance of shock.

This depends on how many outlets you have and the current status of your electrical system. The cost to ground an outlet clocks in at $75 to $480 per outlet, so multiply that by the number of outlets in your home to arrive at a rough estimate. However, this is for simple projects with no obvious issues with the system. Your final bill could vary widely from your calculations.

You should never unplug or touch a buzzing outlet. If there are appliances plugged in that are causing the buzzing, wait until the appliance is turned off (or turn it off yourself) and then unplug it from the outlet. Test the outlet by plugging in something that won’t use much power—a small lamp works well. If the outlet still buzzes, have a pro investigate why.

You should not attempt to disable a smoke alarm unless you’ve already activated a replacement unit. To stop a hardwired smoke alarm from beeping, reset the device or silence the alarm. If you’re removing a hardwired alarm, shut off the power, turn the unit counterclockwise to remove it from the ceiling, and disconnect the wiring.
