Great service at an super affordable price!

Nick was an awesome technician! Not only was he friendly and professional, but he was very knowledgeable and helpful at explaining the service and process to me. I had an EV charger installed and Nick was quick and efficient. He also encouraged me to get a surge protector installed which I greatly appreciated. The finished product looked amazing and the charger work better than expected!

Worked hard to avoid Drywall Damage

Matt was professional, helpful, and responded to my concerns. He got creative and was able to avoid damaging drywall while running new wire to add a drop for a smoke/co2 detector. I would have liked a bit faster install after consultation and the work cost more than I'd hoped, but he did a great job and I think I got quality work for my money.

Great Price on Tesla charger installation

My service technician Alex Weber was on time, kind and knowledgeable about electrical wiring. He gave me some advice on EV chargers if I plan to move from my home in the future. Alex also got the job done in timely manner. I would recommend him and Haas and Son’s for any electrical work needed in my home

Fantastic service

Haas & Sons was able to get someone out to look at electrical issues without a long wait; showed up early (after phoning to ask if it was okay to move the appointment up), and managed to complete all the work the same day. Alex was knowledgeable, efficient, and friendly. He explained everything thoroughly, and made sure we understood everything before starting the work. We were super impressed he was able to get everything done the same day, and we were very satisfied with the work.

exceptional quality and service

I was having electrical issues throughout the house and called in to schedule an estimate. Nick came out next day, laid out multiple options for me, and was able to go to work same day. I got a heavy up, needed grounding, new panel, new meter, etc and Nick knocked it out a day later. He took great care in putting in the new panel and could tell he takes pride in doing it right. It looks awesome now and of course working great. The owner takes your calls as well to help diagnose and plan, they’ve got a great email/text notification system, and very timely appointments. Definitely recommend.

On first floor bathroom i added a receptacle next to the toilet. I had to cut holes and go through the studs due to lack of access In the master bathroom i jumped out of a existing outlet and ran my wire into the attic then dropped down the wall next to the toilet and cut a old work box and added a receptacle These receptacles are controlled by the first floor bathroom gfci so they are protected and code compliant

This solution includes installing a 100 amp sub panel next to the main panel in the basement due to the fact that there are tandem breakers in the main panel also incorrect wiring two breakers multi feeds that are going to 15 amp and then 20 amp single pole breakers so we will separate those wires and move wires to the subpanel allowing more spaces in the main electrical panel also it will fix all the safety issues allowing the main panel to last longer And safer We will run wires from an existing receptacle in the basement then run or wires throughout the basement and install three GFCI’s in the basement where the customer wants them these circuits must be GFCI protected due to the fact that it’s an unfinished basement with a concrete exposed floor Previous electrician put a plastic box on a concrete wall and installed a regular receptacle in the basement I will remove the plastic box and the receptacle and put a metal 1900 box with a GFCI receptacle and RS cover plate for deep fre

Was called out due to circuits randomly tripping. Checked the panel and random circuits throughout the home. Found nothing that would cause any safety concerns. We recommend calling BGE to have them come monitor your electric to see if there is any spikes in power. It could also be possible the breakers are faulty but we recommend calling BGE first. Please let us know if you have any questions. Thanks!

Reason for today’s visit was to look at installing customer supplied car charger. Paul initial inspection I found that the main panel is located in the garage in the front corner right next to our customer desire to have charger installed. Customer has a Square D home line series panel with plenty of space that was installed in 2019. Customers charger is a pulsar plus that came with a 50 amp cord. I removed the cord and installed liquid tight flex tubing from the new charger into the main panel. I installed a new line that is good for up to 60 A from the panel into the new charger install a new 50 amp breaker to power the 40 amp charger. I also noticed the main panel did not have whole home surge protection in which I recommended installing. Customer had me install the home line plug inserts protector while installing the charger. I relocated the dryer breaker from the bottom right spaces (#1 & #3) I relocated it to space is 21 and 23. And then installed the charger in spaces one and t
