Frequently Asked Questions
Warning signs include frequent circuit breaker trips, flickering lights, and a persistent burning smell near outlets. If your home still uses ungrounded two-prong outlets, cloth-insulated wiring, or aluminum wiring, the system is likely at the end of its safe operational life. These aging components can become brittle and pose a significant fire hazard as they struggle to handle modern electrical loads.
A full house rewire typically takes between 5 and 10 days, depending on the size of the property and the accessibility of the wiring. The process involves pulling new cables through walls, replacing the electrical panel, and installing new outlets and switches. We work in stages to minimize the time any single area of your home is without power.
We use specialized tools to "fish" wires through existing wall cavities via the attic, crawlspace, or basement. While we aim for a non-invasive approach, small access holes are often necessary near the ceiling or behind outlets. We identify these points ahead of time so you can plan for minor drywall patching and painting once the new circuits are tested.
A partial rewire focuses on specific high-load areas, such as the kitchen or a new home office, or replaces only the most hazardous sections of an old system. A full rewire replaces every foot of cable from the electrical panel to the furthest outlet. In 2026, a full rewire is the only way to ensure 100% compliance with current safety codes and grounding requirements.
Knob and tube wiring lacks a ground wire and has insulation that becomes brittle and flakes off over time, exposing live copper. Aluminum wiring, common in the late 60s and 70s, expands and contracts more than copper, which leads to loose connections and arcing at outlets. Both systems are leading causes of residential electrical fires and often make a home uninsurable.
Yes. A modern, code-compliant electrical system is a major selling point and a standard requirement for home inspections. It provides buyers with peace of mind regarding fire safety and ensures the home can support modern technology and EV charging. Many insurance companies also lower premiums once a certified electrical rewire is completed.
Most homeowners choose to stay, but you should expect significant disruption. Power will be shut off to specific sections of the house during the day, and there will be noise and dust as we access wall cavities. We provide a room-by-room schedule so you can plan your daily activities around the work zones.
Yes. This is the ideal time to update your home's layout. We can add outlets for wall-mounted TVs, install USB-C charging ports, and add 240V circuits for appliances or EV chargers. We work with you during the planning phase to ensure the new electrical map meets your specific power needs in every room.
Modern electrical codes require AFCI (Arc Fault Circuit Interrupter) breakers to prevent fires caused by arcing wires and GFCI (Ground Fault Circuit Interrupter) protection in "wet" areas like kitchens and bathrooms to prevent shocks. A full rewire includes installing these safety devices at the panel or at the individual outlets to meet 2026 standards.
Yes. If you experience a partial power failure, sparking outlets, or a "hot" wall, we provide 24/7 emergency diagnostics. Our team can isolate the hazardous circuit and provide a plan for immediate repair or replacement to secure your home and prevent an electrical fire.

Posted on Google Omied LeleTrustindex verifies that the original source of the review is Google. Pasha (technician) was very helpful. We had a clogged drain and were unable to clear it ourselves. He arrived and fixed the drain and was very clean and polite. Left everything as it was before he arrived. Highly recommend.Posted on Google Liang KatherineTrustindex verifies that the original source of the review is Google. Fantastic service! We really enjoyed working with United plumbingPosted on Google Natalia ShreveTrustindex verifies that the original source of the review is Google. Pasha was very professional he gave us a couple of options and finished the plumbing job very quicklyPosted on Google Just JaniceTrustindex verifies that the original source of the review is Google. As a busy homeowner I truly appreciate their ability to work around my schedule and needs. My garbage disposal recently died, and Neo was professional and offered my different options. He had the parts I needed and was able to complete the job quickly and cleanly.Posted on Google Chaozhong LianTrustindex verifies that the original source of the review is Google. I wholeheartedly recommend United HVAC, Plumbing & Electrical. I recently hired them to replace the original 1961 HVAC ductwork in my house, and they did a wonderful, extremely professional job. I am beyond satisfied with the results. You don't just have to take my word for it--I actually took pictures of their completed work, uploaded them to Google Gemini, and asked the AI to evaluate the installation. Even the AI praised their work, calling it a "top-tier, textbook installation"! (See the screenshots below). During the bidding process, I compared United with another company. United's quote was slightly higher, but choosing them was absolutely the best decision. Their program manager, Tim, was incredibly easy to work with. He quickly identified asbestos tape on my 1961 ducts and insisted we use a C-22 licensed abatement company to remove it safely and provide all the legal documentation for future reference. The other company offered a cheaper route by doing the removal themselves, but for something as dangerous as asbestos, doing it by the book is well worth the minor price difference. I also want to give a massive shoutout to Bair (Bayar) for his exceptional craftsmanship. He is easy-going, friendly, and really listened to all of my concerns. He provided great recommendations on how the new ductwork should be organized, and actually used a machine to fine-tune and balance the air pressure throughout the house. To top it all off, he even carefully reorganized the insulation in my attic after the work was done! It's this kind of attention to detail that makes them stand out. The pictures speak for themselves. If you want true professionals who care about safety, honesty, and quality craftsmanship, go with United HVAC.Posted on Google Chaozhong LianTrustindex verifies that the original source of the review is Google. I highly recommend United HVAC, Plumbing & Electrical! From start to finish, the entire process was incredibly smooth. They handled all the permits and inspections throughout the project, which gave us complete peace of mind. Every single technician we interacted with was friendly, approachable, and truly easy to work with. I specifically want to give a massive shoutout to Max (Aiusha) and Rinat for their wonderful work. Max is super professional and highly skilled. He installed my water heater and water softener with absolute "military precision." I'm the kind of guy who has a lot of weird, specific ideas about how pipes should be routed and extra gadgets I want installed to monitor the system, and Max handled all my requests with total ease. I am also super paranoid about plumbers plowing through studs or structural beams in my 1961 house, but Max was extremely careful and treated my home's structure with the utmost respect. Rinat is also a fantastic plumber. He installed a PRV, a Moen Flo auto-shutoff valve, an RO system, and even replaced some of the old sewage pipes in my house. He really listened to all of my requests and finished the job quickly and professionally. I highly recommend him! Because of their wonderful service, I’ve officially signed up for their company's membership. I am currently working with them to redo my HVAC ductwork, and I will definitely leave another review for that project once it's done. I'm sure they will do a wonderful job there, too!Posted on Google Ritesh BediaTrustindex verifies that the original source of the review is Google. Great service. Loved the professionalism and the way fixed my plumbing problem. I would call them again.Posted on Google Ginger PerngTrustindex verifies that the original source of the review is Google. We had to replace the wax ring on our toilet. Scheduling was easy; pricing was fair (much cheaper than the other quote we got!) Our technician, Melvin, was polite and expedient. This is our second time using United and highly recommend for gas and plumbing services.Posted on Google Joseph MartinTrustindex verifies that the original source of the review is Google. Melvin was great. Fast and efficient.
