"Making Plumbing and Drain problems disappear since 1980." Magic Plumbing has performed emergency plumbing, sewer and drain cleaning for over 25 Years. We are open weekends with no extra charge. From sinks to sewers, we do it all. Using flat rate pricing, our knowledgeable technicians have the experience to solve most plumbing and drain problems immediately, providing an estimate for your approval before beginning any work. Specializing in trenchless sewer line replacement, we use video equipment so we can pinpoint the exact cause of a sewer problem in order to advise you of the best possible solution. We provide free video camera inspections for homeowners and property managers. For property owners and managers, Magic Plumbing serves many of the top property management firms in the Bay Area, providing fast solutions for all plumbing problems, everyday.

"When I needed to get a water heater replaced before a weekend after calling it on a Wednesday afternoon, they did it. Every other plumber called could barely send someone to give a quote! It can be hard to find a service company in San Francisco that behaves like they want your business so I was truly grateful. And while the job cost a lot more than I expected, they were able to help with the price because I was in a tight spot financially. Also, when I had an issue that I discovered later on with hot water not getting to the hydronic central heating, Adam came back to bleed the line when I was out of town! That's excellent customer service right there! They have a great team and they run a tight ship!"

Service Champions is the leading heating and air conditioning contractor in Northern California servicing homeowners in East Bay, South Bay and Sacramento areas. We can make your home more comfortable and improve the quality of air you and your family breathe. We specialize in maintenance, repair and sales of all brands of air conditioners and heaters, and are experts in indoor air quality improvement through filtration, duct replacement, insulation and hospital grade UV lights. All the air conditioners we install have the new environmentally friendly refrigerant that does not damage the ozone. We also are huge proponents of super high efficient equipment, such as 95% efficient furnaces. This equipment saves homeowners a tremendous amount of money on their utility bills.

"Just had the initial diagnostic visit. I was given terrible news (I'll probably end up getting a new furnace $$$), but the technician Ricky was wonderful. He was extremely polite, professional, and friendly. He did a very thorough inspection and then gave me a very thorough explanation of the problems. This included photos he took on the spot of some internal parts (oil leakage, heavy dust & dirt, stress markings).... at no point did I feel like I couldn't trust what he was telling or showing me. He answered every question I had. He went into the "attic" of my Eichler to check the ductwork (via a 14" hole in the closet ceiling, into space so shallow and tight I have no idea how the ductwork was ever even installed), and came out with photos to show me. The company was easy to work with when I had to change appointments, sent me email and text confirmations of everything, and gave me a day-before reminder of the appointment. I had an 8a- 11a window and received a text at 7:50a letting me know the technician was on his way, with a photo of him included. Perfect, perfect, perfect. The visit was $89 but reduced to $39 because I signed up for the MVP membership: $107 for a year which gets me all kinds of free services plus discounts on everything else. It even includes services on my water heater which they did not install! Additionally, they have some really good guarantees, MVP or not. Before leaving he called the office, explained all he'd found, and handed me the phone to set up an appointment with a "comfort specialist". Ariel (on the phone) was also extremely polite, professional, and friendly. These people are trained right! Or they're hiring very well. So, I will be meeting with someone to discuss repairs vs. replacement options. No repair work has been done yet (although Ricky did do a temporary fix that is allowing me to get some heat), so I can't fully review the company. But thus far I'm 100% pleased. This is probably the best experience I've ever had with any kind of repair technician. I've never used them before and have also never written a review before. The experience was just that good. I'll write another when I've finished with them just to give a full review, but so far perfect!"
