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.

I was originally called out here to examine the microwave due to the fact that the tenant smelled a burning odor when the microwave was in use. I examined the microwave and saw that it is a insert microwave and the plug is behind it in the cabinet so i was unable to check the electric. But i had the tenet turn the microwave on and I immediately smelled a burning Oder too. This was coming from the microwave itself. This is not an electrical issue but a appliance issue. The landlord mentioned some thing about the stove which is directly underneath of the microwave but the microwave is a 120 V circuit and the stove is a 240 V circuit these are two completely different circuits I went to turn the microwave off but it appears that the microwave is not a Labeled on the electrical panel and it is not a dedicated circuit most likely it is tied to the kitchen countertops so I did not turn off any electrical breakers I did however stress to the tenant do not use the microwave whatsoever as

We removed the existing 200 amp panel and replace with a new one in its place. We installed all new, matching breakers and install water bonding jumper and replace bad Gfci in second floor bathroom.

The reason for today’s visit with the customer was a quote for ceiling fans in each of the bedrooms located on the second floor. After introducing to the customer, the customer then showed me each location that he wanted the fans installed upstairs. Each bedroom had a switch controlled outlet currently and we would be turning that single gang to a two gang to aid in fan switch installation. After inspecting the areas of installation the customer then took me down to the panel located in the basement. I saw that the panel was a 2000 Square D Homeline panel with a 200 amp service. The panel had many violations such as double tapped neutrals and multiple shared neutral circuits where a two pole breaker was required. After we inspected the panel together, we then went back upstairs to the living room where the customer then wanted a second quote on adding six 6 inch recessed lights. Currently there is no lighting in the family room and the customer wants to turn the switch that does the di

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 estimate includes the replacement of the dual function 120V 20A BR breaker controlling the kitchen circuit. We have replaced the breaker controlling the kitchen receptacles. Power restored. We recommend that a surge protector be installed at the main panel.

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
