"The gentleman who showed up was prompt and very courteous, but unfortunately that was the only positive thing I can say.He was here for 40 minutes, charged me 200 dollars and told me he couldnâ t fix it in my garage, because the oil was sludge and he may or may not be able to fix it, but he would have to take it back to the shop and it would cost me 80 dollars an hour to try to fix it.When I gave him a check for his time and asked for a receipt, he looked at me like I was asking for a kidney, and wrote something down on apiece of notebook paper, which was supposed to be a receipt.It was not an invoice with the company name or any reference to their business license.I later received an explanation from somebody in the office, that they would send me an invoice for the work done.I have never had any contractor not present a proper business receipt to me when I have given them a check, prior to this."

Electrical questions, answered by experts

Buying a house with aluminum wiring requires careful consideration due to potential fire risks. Ensure a thorough inspection by a licensed electrician to assess the condition and identify necessary safety upgrades—factor in these additional costs when deciding. While it may not be a total deal-breaker, understanding the risks and required maintenance is necessary. Also, you should consult your insurer about coverage for homes with aluminum wiring to know whether the house is insurable.

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.

If a 3-way switch is wired incorrectly, this can cause several issues. The most common problem is that the switches will not function properly: Either both switches won’t work, or only one will. Another issue is that one switch will trigger a short circuit, tripping the circuit breaker.

When removing an old security alarm system, you likely won't need to remove any of the wiring. Wiring can either be left in place for a replacement system or capped off for safety and pushed into the wall. If you're uncomfortable with the wiring, or if it's badly damaged, contact a professional electrician for assistance with safe removal.

You should aim to replace your electrical outlets every 15 years, although some GFCI outlets can last as long as 25 years. On the other hand, outlets can go bad much earlier if:

  • The wiring is in poor condition.

  • Your circuit is overloaded.

  • There are loose plugs in the outlet. 

  • If the outlet wasn’t installed properly. 

  • If the outlet wasn’t grounded.
