They were wonderful

I was so very happy with the service we received. They guys were quick and professional. Everything was clearly explained and expertly handled. They accommodated our large dogs and ninja cat easily and were very good about making sure everything was safely put back together before they left.

Excellent Service!

Mike was great! Did an excellent job of checking out the problem and made some repairs at my request. It was great that he was able to come out today and address the issue in my guest bedroom that tripped the switch in the panel.. Now I can sleep a little easier knowing the problem has been checked out. He even took a little time and gave my little doggies the attention they wanted!! Haas and Sons Electrical are the best!

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.

We provided pricing to install manual transfer switch next to the existing 1960s main panel for a customer be able to run a few circuits in the home on the generator when power is lost. We are unable to install a generator interlock kit in the panel due to the age of the panel. We highly recommend replacement of the panel with a new larger panel to accommodate the current circuits as well as any future. With this second option, we are able to install in our lock kit, so customer can control the entire home and pick and choose what they want one when they want them on when the generator is powering home.

Today’s reason for visit was to provide a solution on smoke detectors installed in the home. When we arrived, i saw a 200 amp GE panel that was installed in 02. The panel showed many signs of concerns with the bus bar and the neutral bars. There were double tapped neutrals as well as majorly over heated/charred bus bar. I brought this immediately to the home owners attention and we began inspecting the rest of the home. After inspecting the panel, i saw there were multiple low voltage smoke alarms in the home. There were older low voltage systems as well as a 120v detector on each floor. Home owner would like pricing for replacing like for like or moving them to proper locating to meet current requirements. We also provided a solution to meet new NFPA regulations which included installing smoke detectors in each bedroom. At this time home owner would like to take time to decide and call back if interested.

Installation of dedicated circuit for attic radon fan. Radon fan is required to have a dedicated circuit for reliability. Radon fan is also required to have a dedicated circuit to prevent power loss and have no possibility of being accidentally turned off. Radon fan is also required to be on a dedicated circuit so the fan is not off when a shared circuit is accidentally tripped. Circuit will be ran by way of conduit through the exterior of the home and along side the slope of roof and then insert to attic. From the attic we will then install a new outlet for the circuit.

Arrived onsite to be shown the existing hardwired detectors, are the smoke detectors that were recalled, as well as all the battery ones linked to them. We went throughout and found the foyer and office are hardwired, but the rest of the 6 in the house are all battery. They are leaving for a trip for 2 weeks and want them fixed today, but i also discussed the long term fix of hardwiring all the units together as well, which i wrote up an estimate for and will be sending them. For today, we will replace the hardwired unit in the foyer with a combo unit, and the one in the entry office with a hardwired smoke detector. The husband ran out and got battery ones for all the other locations that we installed as well. All detectors are verified working properly and they will reach out when they want to get them all hardwired next time.

Install dedicated plug next to panel Install new dedicated 20 amp circuit next to the main panel for customers plug-in car charger. Issue in the garage was that the 12 amp car charger as well as the other battery packs and stuff on the circuit was causing the breaker to overload trip. This new circuit will avoid this issue by separating the car charger from the rest of the circuit.

08/25 Arrived onsite where we were given the sticker for the inspection corrections needed. We spoke to the homeowners about what would be required to update the other half of the service to modern safety standards, that is being asked of us by the inspector. We will have to add a disconnect for the 125amp line, as well as update grounding, and add a whole home surge protector to the existing cutler hammer panel as well. We will relocate the phone box to the front corner of the house, and pad the wall outside to go over the existing grounding, fiber, and phone lines that are already run. We will return 8/28 to complete this work and fulfill what the inspector is asking of the job. Deposit taken today Returned on 8/28 today and i started inside and Tyler started outside. We had to move the phone box and redo the strapping for the grounds but we were able to fit the 100amp disconnect on the same wall. Tyler worked on the grounding and once we got outside far enough, i came inside and

Replace customer supplied bath exhaust fan in 2nd floor bathroom Reason for today’s visit was to replace a customer supplied bathroom exhaust fan. Customer purchased a new Panasonic fan and one of us to swap out the existing one. He also stated there was a rooftop bent already installed that we just needed to attach to. However, we went in the attic to check. The roofers had completely removed it so there was nowhere to vent out. Customer did not want us to penetrate the roof and put a new vent out in so we installed a siding vent kit which we attach right to the gable right above the bathroom.

Installation of new devices throughout the home including one dimmer on the first floor controlling a foyer fixture, duplex’s in multiple areas (either broken or plugs falling out), box repair and device change for fridge, and two others. We will also replace the current vanity fixtures in both bathrooms on the second floor as well as adding a new exhaust fan located in the hall bath. Install new two gang switch located outside the bathroom to control a wall sconce outside of the bedrooms. Per inspection sheet recommending checking on grounding, we recommended a new whole home surge protector as well as changing shared neutral circuits with common handle breakers and separating grounds and neutrals. Returned today to complete WPQ. We removed the mirrors in the primary and hallway 2nd floor bathrooms and removed the light fixtures. We discovered that none of the fixtures had boxes to support the new fixtures, so we installed new 8B boxes. We removed the old bath fan in the hallway bat
