Alex is and has been always courteous, professional and forthright and answers all our questions. Even though he comes in with his tools and ladders, he doesn’t leave any trace behind that he was in our home other than a job well done. Thank you Alex.

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 and prompt service!

I called on a Monday, had an appointment for Wednesday, got a call back later in the day and was able to secure a same-day appointment for the technician to come out and do an assessment. He was able to come back on Friday to install the outside plug for our electric car charger. The charger we purchased had not yet arrived yet, but when it did arrive a couple days later, the technician was back to install the charger. I would definitely use Haas & Sons again!

We removed the existing lights from both bathrooms on the 2nd floor and installed new customer supplied exhaust fans in their place. We then installed new through the roof vent outs with 4inch venting to remove moisture from home. These new gooseneck vents have built in dampers and squirrel cages to keep birds and rodents from nesting in the vents.

Customer has two second floor bathroom exhaust fans they wanted upgraded. Customer had already removed the hallway bathroom fan. We installed the new customer supplied fan back in the old ones place and hooked back to the original wiring and 4inch venting. We removed the master bathroom fan and installed the other new customer supplied fan in that ones place, hooking back in the original venting and power as well. These new fans needed constant power and came with a new in wall battery operated controller. I removed the old original toggle switches in each bathroom that controlled the fan and the fan lights (4 total). I spliced wires through so that the new controllers would work. I placed new dummy switches (not controlling anything) in next to the new controllers so that customer did not have to remove the switch boxes and need drywall repair. Once fans and controllers were installed I synced the controllers and tested. I then showed customer how to control fans and how to sync their

The customer changed the disposal and then discovered the switch was not energizing the disposal every time. We couldn’t tell last time because the disposal being burnt out. So this time I re deviced the three gang box next to the sink. 1 switch for the garbage disposal. 1 switch for the sink overhead light. And a receptacle. Customer has a 30 day warranty
