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.

Arrived onsite and she showed us to the basement where we were told a few outlets were having issues tripping breakers, and the gfci was tripping for the hvac system supposedly. I went throughout the basment, did load draws on all the circuits involved in this situation and found there were 2 dedicated plugs for both deep freezers that combined drew a max of about 4.2 amps, but then a backup battery system for the whole internet was drawing over 10 amps alone. I separated them out so they wouldn’t cause issues and then addressed the gfci issue. There was one gfci in the panel room that had all the outside outlets, one in the other unfinished area of the basement, and then an outlet that fed the lighting, and the power to the condensate pump outlet on the furnace. I removed the load and she isn’t going to use the one outlet. The panel room needed the gfci replaced because it was bad but i also line sides the line going to the hvac room, so i could put a separate gfci in there to control

Today’s visit was for washer, circuit, continuously, tripping. During assessment, I saw that it was on a dual function breaker. The breaker was unable to sit flush in the panel due to the cold water ground sitting behind it, pushing the breaker forward. This caused the breaker to have a loose connection and deteriorate quicker than normal. I also saw that the customer had a state of the art server and I highly recommended putting surge protection in each panel. Please see below for work performed. Replace (1) arc fault 20 breaker Install (2) whole home surges. One in each panel Install plug in home line surge for sub panel

Today’s visit was for generator receptacle. During assessment, we saw that there were three separate panels. The main panel is a Bryant panel with missing knockouts, aged and one of the sub panels is installed incorrectly. All three panels are full and have no room for generator plug. Please see attached solutions to get these issues resolved for you. Thanks!

Customer originally called because they were having some issues with her undercabinet lights also they wanted to talk about venting a bathroom exhaust fan size we were looking at everything I noticed that there was a dimmer on the kitchen countertop that was controlling the undercabinet lights this was not compatible with the lighting that was only under cabinet lights as they were low-voltage and it was burning up transformer so I recommend that we just change it over to a single pole light switch so the customer does not have to worry about the transformer overheated also for the bathroom exhaust fan I recommend that we change out the fan today 4 inch venting system going through the side of the house doing my safety inspection I wanted to make sure that the panels and safe condition that way when we perform this work there’s no unwelcome surprises.

Service charge I demoed the existing PVC piping in the trench then I installed a new 1 inch PVC pipe from the junction box under the deck throughout the trench up into a spa pack which is now connected to the hot tub it is a GFCI protected 50 amp breaker enclosure then from the spa pack I took a three-quarter inch PVC pipe and went down the trench and installed a Perma post for a receptacle. Then I took metal seal tight and I came out of the spa pack with a three-quarter inch PVC pipe down the line to the hot tub then I did a change over with the metal seal tight and brand new wiring and hooked up the hot tub I also ran a 50 amp circuit from the junction box under the deck to the spa pack to power the hot tub and I ran a 20 amp circuit from the junction box to the Perma post which then also feeds the shed and the landscape receptacles. I installed a new two pole 50 amp home line breaker in the electrical panel. I put on a 20 amp gfci breaker but there’s GFCI’s throughout the yard

Replace current switches located in the guest bedroom on the second floor due to devices having two feeds in the same switch bank causing an electrical short when either is turned on at the same time. New switches will replace for fan motor/fan light and all other wires will be tied together as they are feeders to other parts of the home. Wiring is aluminum and will be properly secured with Alumi-conn connectors.
