I called on a Friday, Monday they did the assessment and the work was completed the following Friday as scheduled/agreed. The electricians were very efficient and friendly, offering advice when and where asked. Nick and Ian were great, would recommend.

Knowledgeable electricians with old school work ethics!

Nick did a fantastic job replacing our old recessed lights with new LED lights. He explained all of my options and made sure I was happy with my choices. He was prompt, professional and very friendly. I felt very comfortable with him and had total confidence in his ability. Ian joined him today to finish the job. He was also excellent. Both men worked very patiently and took pride in a job well done. They both commented that they wanted to make sure I was totally satisfied and happy with the final product. I was thrilled. I will be a Haas and Sons customer for life.

I highly recommend Haas and Sons for any electrical work. They were recommended to me by a friend, and I’m glad I gave them a call. I had a big job done: they replaced all the plugs and switches, electrical panel, mast on the roof, and replaced a few lights in the basement and in addition installed a dining room light for free. I have a really cluttered house and they had to move a lot of junk and heavy furniture to find and replace the plugs, but they were very good natured about it. The crew worked very hard and got the job done quicker than I expected. They were all very professional and pleasant, and I feel confident in their work. I will not hesitate to hire them again in the future.

Replace GE 16 space 100 amp panel with a QO 30 space 100 amp panel. Install brand new QO breakers correctly sized for circuits and to account for any multiwire branch circuits. Update the grounding system with installation of 8 foot ground rods outside the home, run a bonding wire to the main water shutoff, and bond the water heater with a #4 ground wire between the hot, cold, and gas pipe. Install an emergency disconnect outside and by meter in accordance with county safety standards. Install a PSP Vortexx surge with a lifetime warranty and $100,000 of combined protection to meet county safety standards. Haas and Sons will coordinate with county inspectors and BGE throughout the entire process. Called out today to investigate receptacles that were burnt up and not working. Arriving on site, customer directed me to the upstairs office, where I could smell burnt plastic. Opening a receptacle, I discovered the wires to be completely burnt back, caused by a space heater that was plugged
