Excellent Service

Alex is incredibly knowledgeable and professional. He helped guide us through the various options available and was prompt with inspection and service. Will definitely come back to Haas & Sons for any future electrical needs and ask for Alex.

Overall a very good experience

Technician was on time, polite & knowledgeable. The written estimate could have provided more details about the parts and the labor required. The estimate also included the service call fee that I had already paid. The call fee should have been separate.

Customer originally called because the a/c unit was no longer working. When i came out to diagnose the issue i found that the disconnect to the a/c unit had no power going to it. I also noticed that the pull out level was upside down. So i traced the wires from the disconnect to under the deck where i found a cut wire that was energized. So i traced that back to a junction box in the utility room near the panel. It appears someone took the wires apart in the junction box and hooked up the wrong wires to the a/c unit. After taking the wiring the the junction box correctly i found that the disconnect had 240 volts going from its line side and its load side making it so the circuit was back to working. But after that the a/c still was having trouble turning on making me realize it was now an a/c issue. After the hvac technician comes out to fix the unit he will have to turn the breaker back on as we left it off so it didn’t fry the unit. It’s in the sub panel circuit 1,3 on a 2 p

The FANTASTIC customers originally called us out because the attic fan was no longer working when I went upstairs to diagnose the issue I bypassed the thermostat and the attic fan was still not on this means that the motor itself is an issue so we removed the existing motor and the thermostat and we installed a brand new attic fan motor and thermostat I set it to 60° and turned the switch back on and the fan kicked on as designed after that I set the thermostat to 110° as Recommended unfortunately the customers were not home as they were way out of country so there was no reason in writing multiple quotes or multiple options throughout the home these customers are extremely loyal customers and when they need anything done in the near future they know they can call us and we will take care of any issue they have. Also we gave teddy plenty of pets before we left because that dog is awesome

This solution includes us installing a gfci to protect the lamp post light due to water conditions and the national electrical code requirements. We will install a 90 degree pvc pipe down the existing broken lamp post and fish the wires through that way when we put the dirt back it protects to the wires from the sharp edges. Customer is responsible for digging a 18 in deep trench over 15 to 20 inches away from the existing hole. Then dig a whole 18 inches deep to install the lamp post. We will install a customer supplied lamp post with light controlled by a photo cell. We will then concrete in the lamp post and put the dirt back

Today’s visit was for ceiling fan flickering. It only happens when both switches are turned on. After a full diagnosis, I found the fan to be bad. I also saw the devices throughout the home were falling apart and backstabbed. The panel is also rusting out and should be replaced. The breakers inside the panel should be replaced with two pole breakers for he multi wire branch circuits. These issues are going to continue and get worse. The receptacles throughout the home are also painted over and is a big risk for electrical overheating and arcing. I also recommend getting surge protection for the home as well. Please see attached solutions to get these issues resolved for you.

Customer is having issues with dryer. Once on site, I saw that sub panel and main panel are both fused panels and should be replaced immediately. Service cable for overhead service and going to main panel are dry rotted and wire is exposed. Service mast needs to be replaced as it is no longer code compliant. Service disconnect and surge protection should also be installed. Please see solutions to get this taken care of for you.

Customer originally called because the attic fan no longer works. I went into the attic and bypassed the thermostat to see if its the motor or the thermostat. It was the motor so we replaced the gable attic fan with a brand new gable fan and housing and a new thermostat. I also opened the panel and found the grounds and neutrals were not separated in the panel i also Noticed there was no search protection in the panel to protect the homes electronics and the homes utilities I brought this up to the customer and also asked if there was any wish list items they brought up the fact that there is no bathroom exhaust fan in the master bathroom so I gave them quotes to get all these things addressed and then I sent them the estimates as well.

The reason For today’s visit with the customer was loss of power in the garage. Upon arrival, we talked with the customer and examined some of the switches. We didn’t find any power inside any of the boxes which led us to believe that there had to be a GFCI controlling the garage receptacles went down to the panel and examined it and there we found a whole home GFCI. Once we reset this, the power came back on in the garage. We noticed a customer didn’t have any home surge protection so we talked with the customer about this and explained why it was important. The customer didn’t want to move forward with the surge protectors at this time.

The reason for today’s visit was to quote a EV charger installation. After meeting the customer, i was shown the panel location inside of the garage. The panels were a twin 200 amp Ch panel with multiple shared neutral circuits. After inspecting the panel, I was shown the path the customer wanted for mounting the EV charger. After viewing those areas i came up with two options for the customer and at this time no work has been scheduled.

Customer originally called us to come out and take a look at a doorbell that was being an issue also his sunroom was constantly tripping the breaker and you were unable to turn the breaker on at all when we got here I examine the doorbell and the breaker in the electrical panel I noticed that the breaker itself to the sunroom was tripping immediately and they didn’t tell us if there’s a dead short somewhere along the circuit I also found a transformer for the doorbell and it was undersized for a video doorbell camera. When i opened up the receptacles in the sun room i found the faces of the receptacles We’re falling apart and I found a receptacle that was broken and a hot was touching the back of the metal plate causing the dead short so we replaced all the receptacles in the sunroom we spliced all the appropriate wires together than pigtail office place taking the single wire to the device crew clamping it then tighten down the screw to ensure the best and safest possible connection t

I ran a 3-3 romex wire from the main electrical panel through thr basement up into the kitchen area for a range plug. I demoed the existing 6-2 aluminum wire and plug and 60 amp breaker from the panel. I landed our new circuit on a 2 pole 50 amp ch breaker and installed a 4 prong flush mount plug for new range I ran a #4 ground wire from the water shut off valve to the Main electrical panels then irreversibly crimped another #4 wire to it and landed them into the 2 main electrical panels for a better and safer grounding system. I also bonded the home at the water heater
