Amazing work by Michael of Haas Bros

Michael called to let me know he was nearby and showed up quickly. He looked at the work, found the problem quickly. A former electrician had used wrong materials. He corrected the problems and worked diligently and fixed the problems. Plus, he was kind to my dogs that kept wanting to help him. Thank you for a good experience.

Great service, great technician, prompt arrival, total cleanup after job done, BUT expensive and without an opportunity to compare prices between el

We are previous customers. Unless policy re $89 fee gets changed, I’m not sure how likely we’ll be to continue with Haas in spite of excellent service by Alex and previously by Larry.

Awesome Service!

I called in and was able to book an appointment promptly. Michael came out in the promised time frame and alerted me of when his estimated arrival would be. Once he was here, he was extremely professional, courteous, and knowledgeable. I would 100 percent use his (or the company’s) services again.

Quick and good service.

The young electrician was friendly, polite, helpful and fixed my ceiling fan quickly. He also checked the rotation (winter or summer) for me. The price to repair is the cost of a new fan, but this one is a favorite.

The kitchen nook light it’s not working because the dimmer switch and shorted out. This may have been due to the bad spices that were behind the switch or it could’ve been because of the light itself. I repaired all the spices behind the switch and install the new standard single pole switch at customer request.

During my annual inspection of the entire home, I noticed a couple of things that need attention. The outside ground fault receptacles were not weather resistant. The GFCI on the front was smoking when I pressed the test button. The receptacles throughout the home are very old and original to the home which was built in 1983. Some are backstabbed which can cause loose connections over time. I recommend replacing devices throughout the home especially the outside receptacles. Please see attached quote to re-device the whole home minus the exterior receptacles I will be replacing today.
