Affordable, knowledgeable, and available!

Haas is a great company and very professional. I called in an emergency 2 days before Christmas and the owner himself answered the phone and was extremely helpful. His calm, kind, demeanor helped me to feel at ease in a tense situation. He got someone to my house within an hour and a half! Matt, our electrician, was extremely personable and knowledgeable as well. He handled the situation and gave us great advice moving forward. We will definitely use Haas for our future electrical needs! Elizabeth

Electrical wiring repair - residential

Mike from Haas and sons was very professional, prompt amd efficient. Our house is old amd we had to replace all of our electrical box connections in the kitchen and bathroom. Mike was very thorough in his diagnosis and up front about the costs and scheduling. $3400 and two days later our electrical problems were solved. No issues since.

Once again, Nick did a fantastic job in our home. We needed a solution to deal with a breaker box that was full. Nick gave us all of our options and did not pressure us one way or the other. Once our decision was made he finished the work the same day. I highly recommend Haas & Sons for all of your electrical needs.

Chandelier Installation

We had a chandelier to be installed in the foyer with a 20 foot ceiling. Mike did a great job with the installation, arrived on time, and worked with us on the correct height for the chandelier. We have used him before and will use him again.

Original call was to check power to exterior and garage. After checking the circuit, all wiring came from the gfci in the panel room in the basement. This circuit powers the exterior receptacles, utility room and panel room room lighting as well as garage lighting and garage door receptacles. Several receptacles were without a neutral and lighting was without power. After dissecting the circuit I found all terminations were made with the stab in method. I recommended that these devices be replaced and remove the lighting from the load side of the GfCI protection. We installed new gfci receptacles on the rear exterior of home and the basement HVAC closet. In addition we corrected all terminations along circuit.

Initial reasoning for call out was because the smoke detectors were making noise when there was no smoke present. After inspecting the units I found that they were installed when home was built in 2007. The units were manufactured 10/06. This is well past the recommended replacement time frame of 10 years. You could even smell plastic burning inside the old units. We replaced the old bedroom units (4) with new hard wired units with 10 year lithium ion back up batteries. These units do not need battery replacements for the entire life of the unit. We also install 3 new smoke/ carbon monoxide detectors in the home to meet safety and code requirements being that the home has an attached garage. These units were install in place of the top floor hallway unit, 1st floor hallway unit and the basement unit. Once installed we ran a test cycle on the units and they all checked out properly.

We have completed the aluminum to copper repairs in the kitchen and hall bathroom. We have also installed arc fault protection for the kitchen appliance circuits and the kitchen lighting. Bathroom and kitchen lighting is on the same circuit. Circuits now labeled in panel. The kitchen lighting circuit was already labeled as lights and receptacles. This breaker is directly under the new Arc fault breaker.
