Excellent Service and Support

As always, Haas & Sons specialist arrived promptly (at the early end of the time slot) assessed my remaining questions and concerns and effectively installed the lighting appliance they helped me order. Installation worked as planned and with his guidance I was able to activate Ring software quickly. Install was done in an hour. I appreciate prompt service as a club member.

- V.I.P Membership - Installation of a ceiling fan in the living Room - Redevice the Living Room - Panel Corrections Work completed 8/26/25 - Reason for today’s visit with the customer was to finish previously quoted work. To begin I removed the old light fixture that was in the foyer. Once that was down I installed a saddle brace box where the new ceiling fan will be. I then jumped a wire from the existing light fixture box into the new ceiling fan. Due to the style the customer bought the fan wobbles when pulled on hard. He informed me that the one upstairs does the same thing. The switch at the front door controls the new ceiling fan. In the panel I separated the grounds and neutrals and installed a new secondary ground bar. I then made a jumper from the main ground bar to the new secondary ground bar and ran some of the grounds to the new one. At this time all work has been completed.

Reason for today’s visit with the customer was to quote installation of two low volt cat 6A drops and a dedicated bidet circuit. While on site customer also mentioned adding two receptacles in the garage jumping off of the pre-existing GFCI. For the Cat 6A drops i will install two female adapters in the garage beside the panel. I will then run the Cat 6A up into the attic. From there one will go into the office and one will drop down in the bedroom beside the window. The bidet required a dedicated circuit due to being 11.6 amps fully functioning. I will install a 20 AMP AFCI breaker then run the 20 amp line up into the attic where it will the be dropped down into the bathroom beside the toilet. At this time the customer is going to take time to think about it and talk to his wife.

Reason for today’s visit with the customer was quoting a panel, attic fan, and redevice. The panel is a split bus cutler-hammer. I noticed lack of grounding and aluminum wires sharing terminals and lugs. A large majority of the wires inside the branch circuits are aluminum meaning we will need aluminum remediation during the redevice. The home is also missing GFCI protection and does not have interconnected smoke detectors. The attic fan has been disconnected from the junction box. Inside the junction box is aluminum and copper splices. Customer has been provided quotes for the panel, redevice, and attic fan. At this time customer is deciding if he would like to move forward with the home but we discussed financing the job as well. He was not informed that the home had aluminum wiring until today.

The reason for today’s visit was an electrical panel that was shorting causing powerloss to half the home. When we arrived we saw an original QO 100 amp panel that was causing the main breaker to arc and short one leg completely to the home. We began testing voltage and tested voltage at the meter and came to the conclusion that it was the main panel itself. After talking to the home owner about options and giving our solutions, he will reach out if deciding to move forward.

Search protector for the basement TV had blown up, which caused the breaker feeding the circuit to trip. We reset breaker and checked power and everything is back working again.

We will replace the main 200 amp panel in the basement with all new matching breakers and label accurately. We will relocate the overhead service line from the top front of the Home down the side of the home through the basement and into the existing panel location. We will install a service disconnect on the right side of the Home where the new meter location will be. We will bring grounding up to today’s current standards.

Installation of a dedicated circuit for the oven. I will run my wire from the panel roughly 50 feet over to the back of the crawl space. I will then drill down from inside the wall and land it inside a two gang box for a flush mount finish. The name plate is calling for a forty amp circuit. Correcting issues inside the panel such as missing knockouts and shared grounds and neutrals. All work has been completed and upon our departure everything was working as intended.

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.

Arrived onsite and gave an estimate to do recess on the first floor and basment, as well as replace a few lights. Once i went room by room and we had made a plan i wrote up options and we ended up going with the first option, keeping the foyer light standard, replacment of the outside lights, replacment of the dining room chandallier, and installation of 28 and we got it on the schedule for 7/1-7/2 Day 1: Arrived onsite and began by discussing where we would begin the project which ended up being the basement. We started by covering the whole basement area where work was being done in plastic, and then i measured out all the lighting and cut it all in and then we worked together to remove the old lights, make sure the new ones were in a location the residents would be happy with, and then installed them all. Come the end of the day we hit a few snags in measuring because the walls were out a good bit but got the last section of the basement measured out, cut and pulled. We also insta
