Josh and Tyler did a fantastic job

We had a major panel replacement an upgrade that took three days. Josh and Tyler were thorough, professional and a pleasure to work with. They made sure everything was done properly and cleaned up after all the work was completed. They stayed very late on the third day to make sure the house had power everywhere. We would definitely use Haas again for electrical work.

Replace improper switch Require stairs 3 ways Reason for today’s visit was to assess hallway lights not working on top two floors. Upon inspection was easy to determine that the switches had been replaced sometime recently. Customer had recently just purchased the Home and was unaware of them not working. Once once I open the switches, I was able to determine that they were all wired in properly. There was two locations where single pole switches were installed in place of where three ways should’ve been. We took apart all the switches for the stairwell lights and rewired them and installed the two proper three ways. Once installed, we tested all the lights and they are now working properly. We informed customer that if these were wired so badly that he should have the rest of the home inspected as there is many devices to out that I’ve been replaced with the same style devices. We will be returning the next Tuesday to inspect the Home. Inspection homes electrical system 11/4 Today we

Provided three separate prices to replace the main service cable. First option was just to replace the cable as well as install new grounding as well as a new main breaker. Second option was to complete everything from the first option with code updates such as search protection and an emergency disconnect. Our third and final option was to completely update the main panel with a new 40 space 200 and main breaker panel.
