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.
