Great Service

Quick response after initial call. Nick was on time, very friendly and informative and knowledgeable! Showed up day of service, it was an all day job, he never stopped. I highly recommend Haas and sons for any electrical work needed!

Great Service

Nick notified us that he was ahead of schedule and arrived 30 minutes early. We reviewed what the issues were and how to address them. Nick was very thorough and completed the tasks in an exceptional manner. Thanks for everything, and as always, pleased with the results.

Competent, friendly service

Nick has been at my home previously and, as was the case then, he was great again today. He took his time to do the work well and explain the items installed, ensuring that I knew how to operate/adjust them. He was neat and cleaned up after. An overall good experience.

Amazing Service Experience

After calling several other electricians in the area and being sorely disappointed by their lack of response; I called Haas and Sons Electric. They were amazing. Price quoted is the price that I paid. The work was done in an effective and efficient manner with no mess made. Additionally, they worked with me to make my ideas work, within a budget and without unnecessary mess or damage to my home. Nick was amazing. Personable and friendly; a real asset. I am extremely pleased with their work and the customer service I received. Anyone who lives in Maryland knows customer service is often lacking but, not in this case. I highly recommend Haas and Sons. I will be using them next for some smart switches and replacing my outlets.

Installing new motion Flood lights with LED lamps. These lights work as security lights and turn on when they sense motion and shut off at set times once motion stops. Installed exterior outlet with I use cover for Christmas lights and outdoor electrical equipment.

Whether you want a bathroom exhaust fan replaced or a new one installed they too come in a variety of shapes, sizes, and quietness. They do make replacement exhaust fan kits where you get a new motor and grill, but if you're trying to remove the steam build-up you will need to upgrade your exhaust fan. Depending on the size of the bathroom normally dictates if you need a 50, 80 or 110 cfm exhaust fan. Of course, we also need to consider fresh air intake to ensure the fan can exhaust all the air it's capable of drawing.

Choosing the right recessed lights can be confusing. They come in an array of sizes, color output, and brightness. We recommend the canless recessed lighting know as wafer lights. They don't have the restrictions for installation that traditional recessed lights do since they are razor-thin.

Buying a house with aluminum wiring and don't know how to identify aluminum wiring in your home? Aluminum wiring its self is silver in color as opposed to copper wiring. These wires were installed from 1967 and phasing out around 1973. Aluminum wiring pigtails, converting to copper is a good way to make aluminum wiring safe aside from replacing all of it. There are only two approved permanent methods to doing this which are Copalum splices or Alumiconn connectors. Aluminum wiring in a home shouldn't be a deal-breaker but needs to be dealt with by professionals who can make it as safe as possible for you and your family.
