Same Day Great Service

I needed a triple light switch replaced with a mess of wires hiding behind the wall plate. After calling, Alex arrived at my house just a few hours later. He quickly explained the wiring, told me what the fix would be, and got to work. He finished everything up in short order, was a pleasure to talk to while he worked, and even helped me to troubleshoot my ceiling fan that I had installed myself that morning. I'll definitely be calling Haas & Sons for any electrical issues I have in the future!

This estimate includes the installation of a new 40A dedicated 240V circuit. We have installed a new dedicated 240V 50A circuit for use of an EV charger. GFCI protection was included for this circuit. In addition we have installed a receptacle underneath the existing switch in the laundry room.

Customer lost power to the itches lights. The dimmer that controlled the main area lights had burnt up. I replaced the dimmer that controlled them as wells as the lights over the sink with new toggle style dimmers and they turned on perfectly. These new dimmers are compatible with manny more styles of bulbs ad well (including LED).

Removed 3 existing smoke detectors in home (1 on each floor) and installed new smoke/carbon monoxide combo detectors in their place. These new units have 10 year lithium ion back up batteries. I also removed master bedroom closet recessed light and installed new LED recessed light in its place. Checked out kitchen recessed light and found a bad LED bulb and the tab in the light socket was pushed up to high.

Panel has 2 tripple tapped breakers. To fix issue breakers would be removed and install 4 tandem breakers in its place. There is also no surge protection in the home, price includes a surge protector that goes in main panel to protect entire home from surges created from inside the home and surges that come from the utility company. Removed tripple tapped breakers and installed tandem breakers in there place. Now all breakers in panel are installed correctly. Verified proper operation of all completed work.

We have installed gfci protection at counter top location next to fridge. In addition we have looked over the under cabinet lighting system. This lighting system is a low voltage lighting system less than 15V DC, wiring not required to have ground wire, there is no inherent potential shock hazard. Lastly we have verified that the existing rear exterior light fixture is working.
