Circuit Panel Upgrade or Heavy Up Additions
A heavy-up circuit is a type of electrical circuit that is designed to handle a higher electrical load than a standard electrical circuit. This is typically achieved by increasing the size of the conductors and equipment used in the circuit, such as the wires, switches, and breakers. Heavy-up circuits are used in home-based businesses or for home hobbyists where there is a need for a large amount of electrical power to support machinery, lighting, or other high-demand equipment. The term "heavy-up" refers to the process of upgrading an existing electrical circuit to handle a higher electrical load.
Circuit panels may need an upgrade because they're outdated, don't have enough circuits, or you've done an addition or added additional features to your home that require more circuits. Installing a pool or hot tub are just 2 examples of upgrades that might require an update to your circuit panel. We also install circuit panels for new construction of Additional Dwelling Units (ADUs) and other residential buildings.
Dedicated circuits
There are other reasons to have a dedicated circuit besides the electric car charger mentioned above. You may be installing a pool or hot tub that requires its own circuit for safety or code requirements. If you've noticed issues like a hot tub plug getting hot, it could be a sign that your current setup isn’t handling the load safely. .You may be running power down to your outbuildings, or adding air conditioning or an electric stove to your home where you had none previously. There are a variety of reasons you may need a dedicated circuit - our team of licensed electricians near you can help you make the need a reality!

Job Locations and Reviews
For this job, I came out to perform our annual electrical check up to extensively set eyes on all aspects of the electrical system starting with a thermal scan of the panel, checking connections and cleaning the interior. I opened up switches and receptacles throughout the home to check the wiring, everything looked good and there were no “ backstabs” present. Smoke detectors in proper locations. The only suggestions I have are to add surge protection to the panel, remediate the improperly wired multi wire branch circuits, replace washer receptacle with a GFCI and install a disconnect at the water heater, all safety minimum requirements of today. I also replaced the kitchen table light as well as the switch controlling light with a dimmer. Replace kitchen light fixture Replace switch with Diva Dimmer
We will replace (2) receptacles with new GFCI ones that are required by code to be installed in certain conditions. Those conditions would include any receptacle within 6 feet of a water source must be GfCI protected. Additionally we will add a GFCI receptacle with audible alarm so customer can be alerted when GFCI trips and can respond accordingly
Install 4 GFCIs, 2 in the main bathroom, one in hallway bathroom, and one outside by the basement sliding door. Rewire GFCI in first floor hallway bathroom to be point-of-use. Circuit is currently protected by one GFCI in the first floor bathroom, but rental inspection requires GFCIs in each location. Due the current GFCI also protecting the outside outlet, we would also have to install a GFCI there to provide the necessary GFCI protection. GFCI outlets on the deck are on a different circuit.
Replace panel with QO 200 amp 40 space panel. Install brand new QO breakers correctly sized for circuits and to account for any multi-wire branch circuits. Update the grounding system with installation of 8 foot ground rods outside the home, run a bonding wire to the main water shutoff, and bond the water heater with a #4 ground wire between the hot and cold water pipe. Install an emergency disconnect in accordance with county safety standards. Install a PSP Vortexx surge with a lifetime warranty and $100,000 of combined protection to meet county safety standards. Haas and Sons will coordinate with county inspectors and BGE throughout the entire process. We will replace the post lamp that is constantly falling with a brand new secure one
Replacement of the existing heavily corroded, over heated, and rusted sub panel for the home. Panel shows many signs of each hazard and recommend on replacement as soon as possible. We will replace with a new Main Lug Only panel with all new breakers and backer board to provide a barrier between the exterior wall/moisture to prevent this happening again. Once the panel has been replaced, we then go through the home and replace-label the entire panel circuit by circuit to provide a better location point for each breaker. Panels are covered by a 10 year warranty. Installation of new low profile arm bar box for the kitchen light. Currently the fixture requires a low profile arm box due to the I-beam running parallel to the center of ceiling as well as the ducting for the HVAC vent in the ceiling. We will install the new box offset to the current hole in the ceiling and install customer supplied light fixture. We will also replace the current switch with a new dimmer.
I'm in the process of moving out of my home and preparing it to be a rental. Dennis & Brenden arrived on time and were both extremely polite and friendly. I loved that I received a text (the same time they called with their ETA) with the name and photo of Dennis, so I felt comfortable letting them into my house. I went over the list of items I wanted to have completed, and they also walked through the house to do a sort of "rental inspection" with me to go over items that would normally need to be addressed when applying for a Howard County rental license. They replaced multiple outlets, fixed my 3 way switches that didn't want to work as 3 way switches, and also brought a few other items to my attention that were safety concerns. They didn't complete any of the work until we discussed it all and they provided me with a cost of the work. At the end, when going over the completed work, we were turning switches on and off, including the front porch, and at the moment one of the porch lights went out. They could have easily left and headed to their next job and let me deal with changing the bulb (which I said I would do), but instead, they removed the light fixture, replaced the bulb, cleaned the glass panels, and reinstalled it. They even provided a hotspot for me to use when they had to disconnect my wifi due to replacing the outlet it was plugged into. Talk about amazing service! I have a few other projects that will need to be done this summer, at this house and the new one, and I'm happy to know that Dennis and Brenden will be the crew that is sent out to do that work as well. I highly recommend Haas & Sons Electric!
Ian was awesome!
Ian and Tyler were on time, professional and went over the work plan with me to ensure I received the service I wanted. Clean up was excellent too. Definitely plan to have future work done by this team!
excellent service, prompt and efficient
Professional and knowledgeable
Yes, I was very satisfied with the service on yesterday. Nick did a phenomenal job with servicing the electrical problem and sharing knowledgeable information for future references. I definitely would use the service again.
Dennis succeeded in promptly troubleshooting and identifying the cause of our electrical issue. He then repaired the faulty outlet, while explaining why it occurred.
We had a major panel replacement an upgrade that took three days. Josh and Tyler were thorough, professional and a pleasure to work with. They made sure everything was done properly and cleaned up after all the work was completed. They stayed very late on the third day to make sure the house had power everywhere. We would definitely use Haas again for electrical work.
Very meticulous and thorough. Fast service.
Dennis was great and so was his team. They were here for two days and worked so hard. They did a great job. I highly recommend these electricians.
