"As a private real estate investor, we have a lot or properties and hire a lot of contractors. CJ electric was outstanding. He did what was asked, took care of the permits and took care of the project without us having to oversee him. He also a needed trust factor as we did this project by communicating from afar. Truly a pleasure to work with someone like this."

Electrical questions, answered by experts

Smart light switches are designed to be compatible with most lights and traditional home wiring, but there are several key factors to check. First, verify your home's wiring, as some smart switches require a neutral wire to operate, which may not be present in older houses (often built before 1985). Always check the wiring requirements for the specific model you choose. Second, consider your light bulbs; while smart switches work with almost any light, using a dimming feature requires dimmable bulbs, such as dimmable LEDs. Finally, ensure you have the necessary network connection. Most smart switches need a Wi-Fi connection for remote control, but some older models might use other standards like ZigBee, which would require a compatible hub.

Compared to amps, volts, and watts, ohms are a different kind of measurement, though also very common. Ohms show the resistance of materials like wiring: How much they impede the flow of electrons. The reason household wiring is usually copper or aluminum is that these materials are affordable and also have lower ohms, which means low resistance/high conductivity.

You can tell if a breaker is GFCI by looking for a red or yellow test and reset button that you can press in and out. You’ll know if an outlet is GFCI if the red reset button is located in between the two pronged sections.

A voltmeter measures the voltage of AC or DC electrical current. Unlike a multimeter, measuring voltage is a voltmeter’s only function. Voltage is the potential difference between two points within a circuit. Measuring voltage with a voltmeter can help identify wiring issues or determine whether a battery is dead.

An electrician can handle wiring issues with the garage door opener, like faulty connections, circuit problems, or sensor malfunctions, but they’re not the right person to hire for mechanical repairs. Garage door specialists handle things like broken springs, tracks, and panels, while electricians step in if there’s an issue with power supply, motor function, or safety sensors that aren’t responding correctly.
