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).

Moving an electrical meter in your home depends on what your electric utility company allows. If you only want to move it a few inches, that may be no problem or only incur light fees. If you want to move it a significant distance, you may need to arrange a utility inspection and get permission, or your utility company may prevent it altogether.

Yes, you can use a dimmer switch with an LED fixture, but it must be a dimmer that is compatible with LEDs. Check the manufacturer’s information to ensure the dimmer works with LEDs, as not all dimmers are compatible with them. Many smart light switches accept LEDs, but be sure to read the details on the packaging.

There are several indications of an overloaded electrical panel, such as frequent circuit breaker tripping, burn marks, or flickering or dimming lights.

If you’re observing any warning signs, turn the circuit breaker off, then shift some devices from the overloaded circuit to a different one. If there are still signs of overload after turning the circuit break back on, contact a professional electrician to help you fix the issue.

You should hire a licensed electrician who is insured to perform any electrical work on your home, including lighting installation. States have different requirements for licensing and certifying electricians, so use Angi’s state licensing tool to review local guidelines.

Here are a few questions to ask electricians before hiring:

  • How many years of electrical experience do you have?

  • Are you licensed, bonded, and insured?

  • Do you work with subcontractors?

  • Do you provide a guarantee or warranty on your work?

  • What is the timeline for completion?

  • How do you handle change orders?

  • Can you provide at least three customer references?
