I highly recommend Hamilton Electric and would use them again. While on site Brian also replaced a wall switch that regulates the light, exhaust fan and heat. In the past people have had to cut through the outside hallway wall to have room to replace the switch. and than plaster the hallway wall. Brian replaced that switch in less than 15 minutes."

Electrical questions, answered by experts

Short circuits can cause significant damage to electrical appliances, bodily harm, and potentially death to humans. For this reason, they are a serious occurrence. If you’re unable to find and fix a short circuit on your own, you must reach out to a licensed electrician for help.

Some portable cooktops are compatible with standard 120-volt outlets, but most induction (and electric) ranges and stoves need a dedicated 220- or 240-volt circuit and 40 to 50 amps to work. If you are replacing an old electric range with an induction one, you likely already have the proper outlet, but it’s worth checking with a local appliance installation company.

Pendant lights are very versatile, and you can almost always find one with your preferred style that accepts your preferred bulb. Today, many fixtures use LED bulbs, though it’s still completely possible to find one that uses halogen, fluorescent, or even old-school incandescent bulbs. The manual that comes with your light should tell what types of bulbs you can use with it.

Most regular three-prong outlets last for about 15 years if installed properly. Outlets may last even longer if they’re rarely used. GFCI outlets last a little longer than regular outlets, around 15 to 25 years. If your home is older than 15 years old, it’s not uncommon to have faulty outlets, but it’s essential to address the issue quickly before it becomes a safety hazard. 

There are several indicators that a single-pole switch is bad: the switch is warm or hot to the touch, sparks are sometimes present when turning the switch on or off, you hear a buzzing sound or other weird noise coming from the switch, the connected light flickers when you turn on the switch, and the light doesn't turn on at all with the switch. If you notice any of these, replace the switch or call a pro straight away.
