Josh and Tyler did a fantastic job

We had a major panel replacement an upgrade that took three days. Josh and Tyler were thorough, professional and a pleasure to work with. They made sure everything was done properly and cleaned up after all the work was completed. They stayed very late on the third day to make sure the house had power everywhere. We would definitely use Haas again for electrical work.

Timely, reasonably priced, quality service

The price was right. They showed up in their expected time window. Provided very good run down on what needed to be done as well as additional information, including small things I could do myself. Will definitely go back to them for future electrical work.

Dennis, couldn't ask for a better, more competent\knowledgeable electrician. He explained everything so a lay person could understand it. Also, he was very personable.

Excellent Work but

Only thing that bothered me was that things were not put back in place. My dehumidifier was tuned off and that is a crucial system in my basement and my wall was kicked so hard paint and drywall fell off. It’s the little things 🙏

The technician was on time very knowledgeable, took the time to address all our concerns and questions. He actually showed me what could be a problem and how to correct the issue. He did have some recommendations but was not pushy which I appreciate.

Installation of new recessed lights throughout the 1st floor of the home. We will install four recessed lights (6 inch gimbal) in the back sitting room. We will derive power from the current switch that controls an outlet and run out a new switch leg for the recessed lights. The lights will then be controlled by a dimmer for ease of use. We will install six new recessed lights located on the sitting room and do the same conversion as the back room in the front with a dimmer install as well. Installation of four new four inch recessed lights located in the children’s play room. We will install a new switch by gaining power from the switch on the back to back wall and install a dimmer for use as well. This includes installing new gable fans in both locations and installing proper safety devices through the kitchen counter tops and installation of a whole home surge.

Reason for today’s visit with the customers was a failing combo alarm in the kitchen. All smoke detectors were from 2021. I recommended replacing all to prevent potential failures in the future and interconnection issues between combos and smokes. Customer requested to just replace the one that has failed inside the kitchen as they are likely moving in the near future. Combo alarm was replaced and was working as intended upon my departure. The alarm that was replaced comes with a one year warranty.

Arrived onsite and the current owner is still living there but the new owner met us on site, and we walked the job. After opening the panel i made several recommendations but the biggest ones for safety was correction of the shared neutral circuits, adding a sure protector to the main panel, and then walking through how we would get the line across the basement and how far it would have to go. After discussing it I wrote up some options and it sounds like they want to move forward but want a day to think about it with everything else they also have to do to the home. I am going to email it to them so they have the quotes and can get it scheduled for when they’re ready.

Arrived onsite today and met the resident in the garage area where he showed me the charger he wants to use. Then he showed me down to the panel area. I could tell by opening it that it was already overloaded, and adding an ev would only overload it more. I opened the panel and began inspecting and found it was an old split bus cutler hammer, that was in really really bad shape, the breakers inside were actively crackling and sparking , as well as cutting in and out of connectivity.. the resident was there for this and we had a discussion about replacing the panels and the process for that, as well as doing the ev, so I wrote up a few options all including the panel because that was the biggest safety issue with this visit. We also talked about running a dedicated feed from the new panel over to the bathroom on the opposite side of the house, that would go up and feed the exhaust fan with a heater built into it. After presenting options the resident was on the same page and ready to mo

Today’s call was for garage receptacle not working. It was also connected to the outside receptacles that were working as well as the receptacle in the basement. Nothing is ground fault protected, and the wires that connect to the two receptacles that are not working are melted together by a staple inside the home. I showed all of this to the customer however, he declined to proceed with the work. Please see attached solution if you should choose to proceed in the future.

The reason for this visit was to assess the damage done from the storm that just passed. We were able to quickly determine that a palled research and went through the house either from the storm or from a lightning strike which caused damage to several pieces of equipment in the home. We noticed that two GFCI‘s in the basement were burnt out, as well as the smoke detectors in the house. We also found that the gate motors were also damaged, causing the breakers to constantly trip and not reset. We went ahead and replace the bad GFCI‘s and tested power throughout the house as well as replaced the bad smoke detectors. We also went ahead and installed two new whole home. Surge protectors in the main panels to protect Home from future surges.

Replace ceiling fan in dinning room and move to front bedroom Replace 4 smoke detectors The reason for today’s visit was to assess a issue with heat in the primary bedroom closet. Customer stated that she was having an issue with humidity building up in the bathroom as well as the hallway bathroom where the skylight is located. Customer stated this issue was not happening when the showers were being used however, it happens when it is extremely hot. Both bathrooms have newer, really good exhaust fans with proper ventilation. I informed customer that this is not an issue we can address that she would need to have an insulation company check it out. While on site, we were able to install a new ceiling fan in place of an existing one in the dining room and move the dining room ceiling fan up to a new fan location that we installed in the front right bedroom. We supplied a new ceiling fan remote for the dining room, ceiling fan and also replaced. All four smoke detectors on the second floo

Today’s visit was for working. We took a look at the panel and the receptacles. Michael was out here a couple of years ago and replaced them. They were in good condition. When looking at the panel, we saw that the breaker was tripped. We recommend replacing the arc fault breaker to prevent any further issues because it is very sensitive and the power outage could have possibly caused it to become faulty. Customer decided to move forward with the work. We replaced the breaker and it was working as intended upon our departure. I also recommend replacing the cover plates for your devices to plastic to prevent them from failing quicker than normal. Thank you for being a loyal customer and we will see you in about six months for your annual maintenance check.
