Air Conditioner Electric Circuit
Electrical Question: I live in an NYC apartment with two roommates and this apartment, though spacious, is really inconvenient. We have a window Air Conditioner (AC) set up in the living room but it only cools down that room and the kitchen, not the little hallway leading into our bedrooms.

This electrical question came from: Stacy, from New York, New York.

Thanks for your electrical wiring question Stacy.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.

    I have an air conditioner unit that vents with a hose to the window. It worked great, but has now shut off. I reset the unit but it does not go on. Whats up with this?

    • Dave Rongey says:

      Hi Kath,
      Sorry to heard about your air conditioner problem. I would suggest letting the unit sit for a while after resetting it, then turn it back onto a lower setting. The hot days that we have been having are placing quite a strain on many AC units, so they may have a hard time keeping up with the heat if they are set to full cooling. If the unit continues to trip off then go over the list in the article above which may help you diagnose the problem.

    I have a living room and a bedroom that have no power, where do I start to fine the problem?

    • Dave Rongey says:

      Hi Waverly,
      When a circuit does not have power I begin by checking by checking for a tripped circuit breaker. If that is not the problem then I identify the circuit at the panel and shut it off and begin checking in the junction boxes of the outlets to look for a bad connection. See the information in the Troubleshooting Section for more information.
      Dave
