"I highly recommend Thundercolt Electric. Gerardo came out, provided a bid and when I advised I was ready to get started they quickly got started on the project which included recessed lighting, new electrical outlets and switches, changing out electrical outlets and light switches, installing a surge protector for the home, installation of ceiling fans and a ring doorbell. Thunderbolt did an excellent job and I would hire them again for any work I may have and Iâ d recommend them to family and friends."

"Mr. Electric was extremely helpful and knowledgeable with the needs for our business. We needed to update our electrical systems since we kept having outlets go out and power go out in various areas of the office. Mr. Electric was prompt, knowledgeable, and able to resolve all of our issues on their first visit to our office. The prices were reasonable as well, especially considering the amount of work that was done and the level of professionalism they have! I will definitely contact them again with any of our electrical needs."

The electrician was professional, punctual, and paid close attention to every detail. The installation was clean, the work was completed efficiently, and everything looks and functions perfectly. It’s clear they take pride in their craftsmanship and customer service. I highly recommend them to anyone looking for quality electrical work. Thank you for doing such an amazing job!"

Electrical questions, answered by experts

To determine if an electrical outlet is blown, look for visible signs of damage such as a burning or smoky smell, burn marks, or a melted or discolored plastic cover. If you notice a burning smell, contact an electrician immediately. Other signs include a plug that keeps falling out or the outlet not working when you test it with different devices. For further troubleshooting, you can use a voltage tester or multimeter to check for power; a reading of zero indicates a problem. Also, check your circuit breaker or fuse box to see if the circuit was tripped and reset it if necessary. If these steps don't resolve the issue, the outlet may need to be replaced.

A C-wire connects your thermostat to your household heating and cooling system to provide continuous 24V power. The furnace's transformer converts household electrical current into this low-voltage power to operate the HVAC system's circuitry. In most configurations, the C-wire connects to the terminals labeled "C" on both the furnace's low-voltage terminal block and the thermostat. In some cases, if a dedicated C terminal is unavailable, the C-wire can be connected to the "G" (fan) terminal at the furnace.

While the National Electrical Code (NEC) does not set a strict limit, a common guideline is to have a maximum of eight outlets or receptacles on a 15-amp circuit. This rule of thumb, which equates to about one outlet per 1.5 amps, helps keep the total electrical load safely below 80% of the circuit breaker's capacity. It is important to consider the power demands of any devices or appliances that will be plugged in, as overloading a circuit can lead to tripped breakers or create a fire hazard. To ensure the safety and code compliance of your electrical system, consult with a licensed electrician.

Tankless water heaters won’t increase your electric bill. Since tankless water heaters are more efficient than tank water heaters, installing one in your home will actually allow you to save money on your electric bill. The Department of Energy estimates you can save $100 or more each year with a high-efficiency tankless water heater.

Yes, a leaking water heater can damage electrical work. Water can seep into electrical components, causing short circuits, tripped breakers, or even fires. The combination of water and electricity is quite hazardous, so it's crucial to address any leaks immediately to prevent electrical damage and ensure your home’s safety.
