Expert service in every way

Hello, Mr. Michael Wendler visited my house to install a 20A ground-fault-protected circuit in my garage, as well as a surge-protection system for my entire house. Michael did a wonderful job and was very good at explaining everything he did along the way. I had many questions (I am a retired scientist), and Michael displayed great patience going everything thoughtfully until I had all the information I needed. He is a terrific representative for Haas & Sons, and I am certain you are glad to have him. For future electrical work, I will be calling Haas & Sons and asking for Michael. Thank you, Malcolm Niedner

Replacing small transformer for ring video doorbell. Older style standard transformers aren’t strong enough to power video doorbells and charge the batteries at the same time. Replaced older twist style dimmer with a new toggle style with a slide dimmer on the side.
