Excellent service, as always!

Once again, Mike of Haas and Sons has provided top-notch expertise re: the wiring in our 1936 home in a historic district. Mike sorted out some old weirdness, made it safe and compliant, and upgraded our bathroom light and fan to a more powerful model. It wasn't the first -- and won't be the last -- time we reach out to them for help!

Nick figured out immediately what the problem was with the connection to the air conditioner and fixed it immediately. He saved us from sweltering under the summer heat.

Today’s visit was for light not working in two different rooms, receptacle loose in laundry area, and install of receptacle in hallway. During assessment, we found that one light had bulbs but the other had a bad switch. Also, the receptacle in laundry area had no box. The basement kitchen needed GFCI protection as well as the basement laundry area. The panel was missing surge protection. I also recommend doing a whole home re-device which we will discuss again at annual maintenance inspection. See below for work performed today: Install whole home surge protection in main panel Install GFCIs in basement kitchen Install GFCI in basement for washer Install receptacle in upstairs hallway using close power source Replace light switch in upstairs bedroom Install box and GFCI in upstairs laundry area

Today’s visit was for garage not having power. Wiring out to the garage is cloth wire and very old. All of the wiring out in the garage is also old and some not even the right size for the circuit. Devices are also old and broken. Front part of switch snapped off as soon as I pulled it out of the box. I highly recommend running new wire to and throughout the garage as well as replacing all devices (receptacles and switches). Please see attached solutions to get this resolved for you.

When I originally came out to check a power outage in the office I noticed that the receptacles were backstabbed when I went down to check the electrical panel and the breaker they kept tripping when I took the panel cover off I noticed that there was a 150 amp SEU cable powering a 200 amp electrical panel after making my discoveries I presented the options to the customer and he decided to move forward with the upgrade option So I installed a 200 amp SEU cable with a new weatherhead going down customers wall outside which will be connected to the powerlines from Pepco I installed a new meter can. I removed the 150 amp SEU cable from the electrical panel and pulled it outside thenI installed a new 200 amp SEU cable from the meter can into the electrical panel. After that I temporally bugged the old SEU cable and the new SEU cable together to power the customers homes Pepco will make the final connections into the meter can after we pass inspection.
