Outrageous High Prices

Haas used a standard cost per job for the work performed. As a result the charge was $800 plus per hour.

Customer originally called us out to install a customer supplied car charger in the garage. When i inspected the area i saw there was a 240 volt 50 amp receptacle where the customer wanted the car charger. After taking it apart i found the wire could be used for the car charger. When I open up the electrical panel i noticed there were double tapped neutrals which i brought to the customers attention. He then decided to install the car charger and fix the panel. I removed the receptacle and the box inside the wall and then i pushed the wires closer to the panel from inside the wall. I brought the wires out of the wall and then installed the car charger. I then installed a blank plate over the hole where the box use to be. I then removed the 50 amp breaker and installed a 2 pole 60 amp homeline electrical breaker. I then removed all double tapped neutrals and separated them so they were on their own screws to meet code requirements also to prevent the neutrals from overheating in t

Today’s visit with the customer was to quote replacing a non-functional ceiling fan in the middle of the living room along with possibly adding two can lights. After meeting with the customer and going over what he would like quoted I came up with two solutions. One solution would’ve been replacing just the ceiling fan and the other would’ve been ceiling fan with adding two lights, jumping off of current can lights up there now, while replacing all lights with new LED retrofits. At this time customer will order new ceiling fan and then call us back out to replace.

Customer originally called us out to check out a broken pull chain keyless light fixture in laundry room. When i examined the issue the customer decided it was best for me to run a 14-3 wire from the light junction box in the ceiling and run that to the outside wall of the room so i could install a single pole light switch inside an old work single gang box. I then supported my wires in the ceiling i then installed a new switch controlled keyless light fixture that we supplied. On my safety evaluation i noticed that the customer had multiple double tapped neutrals inside the panel and they were missing a whole home surge protector. I removed all the double tapped neutrals also the grounds that were incorrectly installed under the screws. The national electrical code required neutrals to be under their own separate screw and grounds may have 2 under the same screw but must be same size. So i made it so the neutral bar is up to code. Also the range circuit neutrals were separated

Was called out for lights in living room not working. Turned out to be the light was plugged into the wrong spot on the switched receptacle. Customer also brought up a GFCI that keeps tripping in the kitchen. I saw it had the microwave, refrigerator, and toaster oven on the same circuit. I let him know it was overloaded. When I looked at the panel, I saw he had no space left and would need a panel replacement to add circuits. Work performed below: Upgrade from 100 amp to new square d QO 200 amp panel Run (2) dedicated circuits for microwave and refrigerator Please also see the referrals for drywall and also the floor. We will cover the expense of the floor but not the drywall. We will be reaching out to you when the inspection is scheduled.
