Quick and Efficient Service

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.

Professional, friendly service!!!

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.

For this job we checked circuit to find reason for gfci tripping. While on site gfci was not tripping at all. We were unable to find any issues on the circuit. Issue could be due to garage door opener beginning to fail.

Reason for today’s visit was to check power loss in the living room receptacles. We found a trip breaker in the generator panel labeled the family room. We reset breaker and everything powered right back up.
