Not all home repair jobs or renovation projects should be done by a homeowner, and anything involved with electricity is usually at the top of that list. While you may be able to install a new light switch on your own or handle something very basic, most residential electrical jobs are best left to a professional. Note a few of those common jobs that you might be tempted to manage yourself but should leave to an electrician, and other times it's good to call a residential electrician for assistance or repair work.
When you notice charred areas behind walls
If you tear down drywall in order to renovate your home and then notice charred areas behind those walls, you want to call an electrician. This often means that there is an exposed wire that is brushing up against the wall and causing this charring, or which is giving off an electrical spark; both increase your risk of a fire. When you see any type of blackened building materials behind walls, call an electrician to check the nearby wiring and its condition and how it's been installed, so the wiring can be replaced as needed.
When getting new appliances
Many homeowners mistakenly think that "energy efficient" appliances use less electricity, but this often isn't the case. Energy efficient usually means that the appliances will devote more of the electricity they consume to their intended purpose; what this means is that your new, large refrigerator may use more electricity than your old refrigerator, but the majority of that electricity will be used to cool the interior of the fridge versus run the motor and other parts. In turn, even if you get energy efficient appliances, you want to call an electrician to check the volts and amps that are provided by the wiring in your kitchen so you can ensure those appliances will get the power they need.
Installing a new ceiling fan may seem very simple, but there are a few reasons you want to call an electrician to do this. One is that a ceiling fan may need more power than you realize; like your new appliances, you want to ensure the wiring in your home can accommodate its electrical needs. Another reason is that the ceiling fan needs to be bolted securely to your ceiling; if you don't do this properly, it can put pressure on those electrical wires and eventually pull them out of place, increasing the risk of an electrical fire.
