SUPER Nice Guy and COMPETENT

Mike knows what he is doing and he is excellent at what he does. What is equally meaningful and great is that he is so genuinely nice. This visit was second time he came to my home. He explains everything and is very much open to answer questions. I was comfortable and confident the work was thorough and excellent. I plan to request him every time!

Amazing service

Genny Ginger from Hass and Sons Electrical responded to install a ceiling fan in my breakfast room. She did an excellent job. She discovered one of my switches was bad and replaced it also. Genny additionally told me about some other switches I should consider changing. Fantastic personality and very knowledgeable.

Excellent Customer Service, Great Expertise

Dennis and Daniel were the absolute best! They arrived on time and provided excellent customer service! I had previously hired another electrician to do this job, and after two days trying to fix my problem, nothing was resolved. However, five minutes on the job, Dennis from Haas & Sons had my switch, light, and ceiling fan working! Dennis also was able to help me make the best decision when choosing another ceiling fan and switch combo for a second bedroom replacement. He gave great advice and expertise. Daniel also did a great job installing the new fan! I absolutely love it! I highly recommend this company, especially if you want the job done right the first time. I will definitely use them again.

Today’s visit was for replacing two light fixtures in two separate bathrooms. Fixtures were unfortunately too tall for the existing location. In order for all of the globes to fit the lighting outlet would have to be moved or the cabinet lowered. Customer said that he will lower the cabinet in each bathroom in order for the fixture to fit. Customer is aware that I was unable to install all fixture globes. Work performed today: Replace (2) vanity lights

customer originally called us out because during the re-device. Previous technicians missed a 3 way switch next to the electrical panel. I removed and replaced the switch. Then customer wanted to add a receptacle under the switch on that wall under the panel but it was a dead end three way switch meaning it did not have a neutral. They wanted to plug in a dehumidifier so the best and least costly option was to add a circuit right under the panel. So i ran a 12-2 wire from the main electrical panel down into a old work box then installed a tamper resistant receptacle and a 20 amp arc fault levington single pole breaker. Then I labeled the circuit on the panel schedule

Today’s visit was for annual maintenance. During inspection, I saw customer had multiple aluminum circuits and also no surge protection. I highly recommended installing alumicons in each electrical box throughout home, installing arc fault breakers in panel, and surge as well to make home safe. Customer would also like fixtures installed for the exterior and in the kitchen. See below for work performed. Install whole home surge protector Install arc fault breakers for aluminum circuits Install alumicons for aluminum devices Replace devices throughout home Replace (2) exterior light fixtures 6/10 We returned today and completed the adjusted scope work. We removed and replaced all the devices throughout the home and installed proper aluminum copper terminations. Once completed, we went through and plug the home and tested all the lights to make sure they were working properly.

I removed existing light fixture In the larger upstairs closet in master bedroom then I brought that wires switch leg over to where I was going to install recessed lights I then cut in for LED wafer 6 inch multicolor recessed lights and ran jumpers in between the lighting and then hooked up the existing switch leg and then removed the single pole light switch and installed a dimmer switch when we turned them on the customer decided having another recessed light in the center so there would be no shadowing on the new closet cabinets Would be a much better approach so I added another LED recessed light in between the two lights closest to the closet cabinets In the smaller closet in the upstairs master bedroom I remove the existing fluorescent lighting fixture and took the existing switch leg and cut into LED 6 inch wafer multicolor recessed lights and ran a jumper between those two lights and install the existing switch leg and then remove the single pole switch and installed a dimmer s

customer originally called us due to power loss issues in his upstairs spare bedroom. When i approached the front door i noticed the outside outlet was broken. I diagnosed the issue in the bedroom and the receptacles were missing a neutral. I also noticed there were no gfcis in the garage bathrooms or outside which is a safety issue also customer had a pvc break outback by the pond. So i removed the devices in the upstairs bedroom and re deviced all the receptacles in the bedroom. Then i removed the bathroom receptacles, the outside receptacles and the garage receptacles and installed gfcis in each location. Outside i installed weather resistant gfcis and in use bubble covers. For the pond i removed the wire and the pvc pipe then installed a 90 degree pvc fitting and ran the wires into a new 2 gang weather proof box and installed two weather resistant gfcis with a 2 gang in use bubble cover. For all the devices i sliced all appropriate wires together then pig tailed off the splic

Customer originally called us out due to a range issue they said when they were using it they saw sparks/fire so the customer did the right thing and turned off the electrical breaker I came out to assess everything that was wrong with the range including opening up the range plug and the back of the range to check the terminations for the record I saw no sparks or signs of arcing in any of the locations it’s my determination that it is the appliance itself that is the issue. Just to be safe I opened up the electrical panel customer has a 200 amp Square D QO electrical panel in great condition the service entrance cable also is in great condition I did notice there was no surge protection on the panel which I informed the customer and gave him a price to get that taken care of customer also had a fan that was not working in the kitchen which turns out it is the fan itself it needs to be replaced as the transmitter is faulty. The devices in the home are older and should be replaced a

Today’s visit was for installing google nest doorbell. During safety assessment, I saw a lot of issues that should be addressed immediately. The panel is a split bus panel original to the home in 1977. Grounding is not up to date and corroded. This would be corrected with panel replacement. Devices throughout home are also old and should be replaced. GFCI protection is not in all proper locations. Please see solutions to get these issues resolved for you including installing your doorbell camera and fixing your ceiling fans.

The reason for today’s visit with customer was to quote changing out some exterior lighting for the back deck and adding two lights for front downward lights. After meeting the customer, we then began our assessment of the home by inspecting the panel and assessing the home. The panel was a newer installed QO panel that had rotting service cable on the load and line side. The panel also had no grounding and was missing a bonding jumper on the water heater between gas and water. The home looked to be in great condition besides the missing GFCI located on the kitchen counter and the washer. The outlets were currently being replaced by previous technician and will be brought up to date when finished installation. Per the customers request, i included a quote on installation of customer supplied lights on the front of the home by way of deriving power from nearest outlet and mounting on exterior siding block. I also included a quote on installation of low voltage transformer for the rear d
