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.

Customer had an attic fan installed when roof was replaced. We installed new wiring from existing circuit by tapping out of the smoke detector in the hallway. We installed a new service switch in the attic right when you enter. We mounted the new thermostat /humidistat to the ceiling joist next to the fan and set it to the manufacturer recommended settings of 110 degrees and 85% humidity. These settings are easily changeable at the unit in the attic is ever wanted to be changed.

Ran a new dedicated 30 amp circuit from the main panel out to the back porch outside the basement door and installed a new 30 amp inlet power box for a portable generator. We installed the box next to A/c line set. We installed an interlocking kit in the main panel so that the generator breaker and the main breaker cannot be on at the same time. We checked all the wiring on the back porch and only needed to repair the wiring at a junction box above the back walk out door. There was no signs of water damage in the lights or the wiring above the lights.

In order to fix said problem we replaced outlet and examined and pigtailed wires behind the device. Also, while at the home the owner wanted flourescent fixtures convert to 120volt LED lamps in garage and basement.
