"I had Don install four ceiling fans and two bathroom fans. While he was there, I had him do some electrical work for me. I will definitely have him come back for other projects at my home. Don was extremely friendly, professional, honest, and knowledgeable. I absolutely recommend Don Harnas."

Electrical FAQs, answered by experts

In general, 200 amps is enough for a house with a square footage of up to 1,800, or the average three-bedroom home. A 200-amp service allows your home to warm and cool itself while running multiple appliances at once. It's a good option for homes that have been extended, or after adding new appliances. 200-amp service is the current standard for homes, so in most cases, it will work for you.

In the majority of cases, you can replace an outlet with a USB outlet. USB charging receptacles install in the same spot as standard outlets and any electrician worth their salt is more than familiar with the replacement process. Additionally, it’s possible to replace yourself, but only if you have prior experience with your home’s electrical system, as it requires handling of wires.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

A full home inspection can cost nearly $350 on average, but inspecting the breaker box specifically is likely to be lower, between $100 and $200. Don’t confuse this service with a basic breaker trip check, which doesn’t take long and is usually billed at $40 to $50 per hour.

If the electrician discovers a serious problem and needs to replace a breaker, it can cost between $100 and $200 in additional expenses. Although rare, replacing the electrical panel typically costs between $500 and $2,000.

Usually, your house panel is one of the key components that must be replaced when upgrading your amp service. In many cases, you will also need to upgrade your meter base as well as other electrical components.
