Rated 4.7 out of 5 stars based on 6 customer reviews

Trustworthy, Communicative, Detailed, and Careful

Nick and Alex were consummate professionals and extremely friendly. They provided us with the technical knowledge about the damage that occurred, what was needed to repair the damage, and identified further work that was needed to make our home code-compliant and to strengthen our protection against power surges--something that a competing electrical company did not do. We felt that they were honest and detailed and that they cared enough about our home to figure out alternatives that would cause the least amount of damage to implement the repair solution.

Expert service in every way

Hello, Mr. Michael Wendler visited my house to install a 20A ground-fault-protected circuit in my garage, as well as a surge-protection system for my entire house. Michael did a wonderful job and was very good at explaining everything he did along the way. I had many questions (I am a retired scientist), and Michael displayed great patience going everything thoughtfully until I had all the information I needed. He is a terrific representative for Haas & Sons, and I am certain you are glad to have him. For future electrical work, I will be calling Haas & Sons and asking for Michael. Thank you, Malcolm Niedner

We removed a gable attic fan that was not working and replaced it with a new gable attic fan with new thermostat We removed the older attic fan going through the roof and replaced it with a new attic motor with 5 blades and a new thermostat We installed these attic fans on a single pole switch which acts as a emergency cut off switch We recommend leaving the thermostats set to 105 degrees to avoid the attic fans from burning up from constant usage

We will re-device the kitchen. We will replace the front and back receptacle with weatherproof receptacles and install inuse covers Reason for today’s visit was to assess power loss to the front receptacle as well as intermittent power loss in the kitchen receptacle next to the refrigerator. Upon inspection I found that the outlets were all original to the build of a home. These devices were installed in 1987 and were backstabbed only. I found out the wires are beginning to pop out of the back of the devices and we’re not pigtailed. I recommended having the devices all replaced to fix power loss issue as well as to avoid future power loss. Today we removed all the devices in the kitchen which included six receptacles and four switches. As they were currently no GFCI protection in the kitchen I installed two new GFCI‘s to protect all the kitchen countertop outlets. I also replaced the kitchen light switch, The dining room light switch, the undercabinet light switch and the disposal swit

We will install a new service cable from the meter to a new point of attachment at the peak of the home. We will need to install a new ground and system to port to bring it up to today’s requirements. We will pull an electrical permit and coordinate county inspections as well as the Power company final time. We are unable to open the panel cover at this time without opening up the wall. If when work is being performed and we find damage or anything that needs to be addressed there will be an additional charge for needed work to be performed.

Original call was to check the intermittent power in the kitchen lighting. I noticed improper connections to the switches and receptacles, stab in method was used. When I inspected the panel I found scorched and loose breakers. In addition upon inspection of the meter and main breaker located in the meter stack I found the breaker was damaged and weathered. This breaker at the meter was loosing an entire phase. I recommended that this breaker and the panel as well as the kitchen lighting circuit be restored to new condition. We replaced the breaker at the meter stack (Siemens 100A), the existing panel and replaced all devices on the the lighting circuit for the kitchen ensuring proper terminations.
