Great Service!

Alex did a great job of rewiring our dishwasher to our house’s electrical system. In just two hours he was able to diagnose the issue, provide a decent quote, install a new outlet under the sink, and get my dishwasher up and running again with no issues at all. I will definitely be reusing this company again in the future.

Great experience

We had such a hard time finding an electrician. When we contacted Haas , from the very beginning we were treated well and Mike the Electrician did a great job.

Great service!

The service man was right on time. He was very knowledgeable and efficient. The price seemed a little high but as the service provider explained, if we had more jobs to be done we would have received a considerable cut in cost. Next time we will try to take advantage of this price cut. I would definitely recommend Haas and Sons.

I re deviced the dinning room and the kitchen circuits I spliced all appropriate wires together and pig tailed off them creating a far better connection that was there previously. I then stripped the wire and hooked it around the device screws then clamped it down and tightened down the screw. I installed new gfcis and tamper resistant receptacles with new plates. Many of the existing receptacles had burnt wires and damaged wires I also removed and replaced two stacker switches in the upstairs bedrooms Also removed and replaced two single poles switches in the hallway bathroom We will need to return to install a 2 pole arc fault 20 amp home line breaker Customer has a 18 month warranty Installed a 2 pole 20 amp arc fault breaker for kitchen and dinning room circuits 10-21-21

Customer had lights out due to a broken 4 way switch. I also discovered the three ways and 4 way were wired incorrectly. I re wired the boxes to make all the switches in the laundry room work correctly then I replaced the switches due to the 4 way being broken and the 3 way when you first walk into the room to the left having a crack in the switch I also replaced two bulbs outside for a security light to stop the light from flickering. It’s possible it’s the fixture. If it is and the customer has us out to replace the fixture we will use the 95 dollars for the bulbs toward that price since the bulbs are new and we supplied them

I removed and replaced all receptacles on the home gfci circuit That included the outside outlets, the master bathroom the upstairs hallway bathroom and the receptacles in the garage on the walls I replaced the receptacles with GFCIs and I replaced the outside outlets with weather resistant GFCIs with in use bubble covers I line sided all the wires after splicing them and pig tailing off the splice. I also re fed the gfci on the right side of the garage due to a broken wire in the wall. I cut a old work box where the wire was broke and ran a jumper between the boxes. This was able to power up the outlets outside and the other garage outlets I had to remove and replace a weather proof box out back by basement door for the gfci because the existing one was damaged Customer has a 1 year warranty on this work I also removed and replaced a gfci in the garage that is controlled by a light switch by the front door.

This estimate includes the removal and replacement of 2 bedroom ceiling fans. Customer to supply fans. This estimate includes the removal and replacement of 2 50cfm bath fan motors on the second floor. This estimate includes the installation of a proper light box to support the existing vanity in the master bath room. We have determined that the stove whip was never secured properly. This resulted in arcing, electrocution hazard, and damage to the wall from excessive heat. We recommend replacing the damaged unit. Lastly we shall return on the 19th to complete scheduled work. We have collected the 30% down. We have completed all scheduled work.

Replace a breaker that was tripping for kitchen lights and outside front plug. There is a heater for a water line that was left plugged in and has multiple spots between extension cords that can let moisture in. Breaker that was replaced is in the number 8 spot.

The light on the side of the home has a bad sensor and a missing knockout seal. I removed the bulbs and installed a knock out seal so no water can get into the weather proof box. The fixture will need to be replaced if the new owner wants it to work

We re-wired the disposal on the last visit, which fixed the power loss to the GFCI next to the sink and the outlet to the right of it. On this visit we found that there was another live circuit in the junction box hidden behind the wall above the disposal switch. We cut the wires off in the attic and set a new visible junction box and dropped a new wire down to the dishwasher and re-fed the outlet on the far right of the counter. All the outlets on the right side of the sink are now repaired properly and working perfectly.
