Simply the best. Had an issue with the heater turning on and off constantly before the thermostat temp was reached. Lots of troubleshooting and outlining potential issues and next steps. Were patient and answered all our questions. In the end, their experience won us over and resolved our issue right away. Will be looking for them next time I have an hvac, heating or plumbing issue. read more

Our Nest detected an issue that I knew we'd been having with our central heater, and the email had a link to book an expert to see what's going on. I clicked on the link since I have always had good experiences with Google products. The Handy service booked us this business and Amili came out. If I could give them 100 stars I would, because out of 19 years of home ownership and dealing with countless contractors and handymen, Amili was by far the best in terms of knowledge, experience, helpfulness, honesty, professionalism, and general human kindness and warmth. The previous few HVAC contractors I scheduled to look at our heater all said to replace the unit, which would cost at least $20K, and with the Trump tariffs, it would go up by $2K more. We were trying decide what to do but I gave this google nest suggestion a try, and it saved us! Amili showed me what was going on, which was just a filter issue (stupid us). The previous maintenance folks didn't do things correctly, and the contractors I got estimates from weren't honest! They just wanted a hefty project. Anyway, Amili was patient and walked me through the entire system and explained what can go wrong and how to maintain myself, and he also recommended another visit to clean the insides of the return ducts and do deeper checks for a few hundred. Yes please! A thousand thanks to this business!! read more

Akida and Amili are simply the best. This is our second time using their services. Once for our heating system and then for toilet issues. They are super knowledgeable and they are great at explaining everything. I highly recommend Supreme Plumbing if you own properties, rent or are a home owner. Thank you Akida and Amili! I truly appreciate the both of you. read more

Update - I have been texting you directly and you are simply posting this here as a response to my review. If you are really are a professional company - you would fix my AC instead of fighting with me offline and help us out. I asked for help multiple times since the weather is cold and also agreed to pay out of pocket. I already texted you every other day and I am not sure what else to do. You are not affiliated with Liberty Home Guard but they chose you to fix our AC in Milpitas and you been at are home 2 times. I can see there are other similar reviews about the same problem which tells me how you really treat customers. (re. your comment - I understand your frustration and apologize for the inconvenience you've faced. However, it appears there might be a misunderstanding. Supreme Plumbing and Heating is not affiliated with Liberty Home Guard. We strive to provide excellent service and uphold professional standards. If you've encountered difficulties with your AC repair, we'd like to assist you. Please reach out directly to us, and we'll do our best to resolve the issue promptly) Review We had home warranty through Liberty Home guard and they seem like a very shady company. First the came and took the motor blower and the related parts without my consent and when the insurance company shipped the new part , they came back and said - it's the wrong part. The insurance company have been trying to contact them but they don't answer. I have been trying to get my AC fixed and even pay out of pocket since Aug 2023 (been 3 months) and they don't respond. Extremely unprofessional. They left the job mid-way and keeping us stranded. Please stay away from this company. read more

Poor customer service, outrageous pricing Techincian left my house open with no note, and didn't call me. Wanted to charge me $600 in overhead plus 3 hours of work and a $30 part. I said no thanks. read more

Took my ~$85 to come out and diagnose an issue, we're perfectly nice and helpful then have been totally uncommunicative since. Will not provide an estimate for repairs and having them here was a waste of time and money. Tried to contact them multiple times through multiple channels. Would not recommend. read more

Not only were the twins professional, knowledgeable, and efficient but they came roughly within a few hours of my call. I contacted another company right before I found them and I still haven't heard from the other company. They were very careful to check with the manual of my unit to make certain their remedies were compliant. Also, I did not want to have another cold night and even though I still needed parts that wouldn't accessable until after the holiday weekend they left me with the best option to be warm while I waited! I couldn't not be happier. Their company and conversation and personable touch was a bonus! Too bad I didn't have any cookies on hand to let them know how much they were appreciated! The twins are the real deal and the Kings of the Thermostat industry! read more

Supreme Plumbing & Heating - New thermostat, awe yeah! - Heating & Air Conditioning/HVAC Near Me - Oakland, California

Big thank you to Akida! My furnace went down on the coldest day this year, he immediately answered my phone call, offered a same-day appointment, and walked me through a quick solution. Amazing customer service, will be first on my list for any future plumbing or HVAC needs! read more

I came to my friends house to let the plumbers in to put a new heater in. The first person came in and started taking out the old heater and then another person came and he looked the same as a first person I was surprised they were twins very nice polite people and one of them had a son with him teaching him all the ropes very good family business I was pretty satisfied with their professionalism and quality of work House sitter read more

very grateful that they were able to promptly show up! Akida and Amili came as soon as they promised and everyday after that, always on time, clean and professional. They quickly new the problem, gave us a quote and finish in a VERY timely fashion. UNMATCHED...I definitely recommend them and I will CONTINUE to call on them. read more

One chilly morning, I noticed our furnace was running but wasn't circulating air around the house. We put in a call to Supreme Plumbing and Heating and and they were able to put us on their schedule within a couple of days. Akida showed up and diagnosed the problem, then returned the next week with his brother to install a replacement part in under an hour. It was a pleasure meeting both of them and I look forward to reaching out when we're ready to consider upgrades to our home heating system! read more

I'm always stressed when looking to hire a company to fix heating / plumbing issue as I've heard of so many horror stories of getting taken advantage of. However, Supreme Plumbing & Heating really hit the mark and I'm so glad I found them. I reached out for them to help install an Ecobee. Unfortunately the ecobee isnt compatible to my home, but they gave very clear directions and options for next steps. I appreciated their knowledge and honesty. They were quick to respond and show up. They were knowledgable. But most importantly, they were honest. read more

TLDR; Tried to charge me $9,000 for a 75 gallon water heater replacement that should have been no more than $3,000. I paid $5k then refused to pay anymore so they've been harassing me via text, phone, at my house, and on twitter. Our hot water heater in our new house went out. The twins seemed like nice guys at first. It took them three weeks to get the problem sorted. After charging me a thousand dollars for a replacement part for my previous heater, they finally ended up saying the heater needed replacement and it would be another $3850 for a new heater, and they'd need the money up front. I sent it via PayPal, after they assured me it would go through immediately. Three days later, (and three weeks since we had any hot water), the PayPal transfer finally went through, they finally went to get the water heater, but it turned out to be the wrong energy rating - so they had to wait another day for another heater to come from Sacramento. After installation they told me I'd need to pay another $4000. Thats ~$10,000 for a water heater replacement. This seemed unreasonable, so I sought bids on yelp for a 75 gallon water heater replacement in an attempt to understand what the average price was. The six quotes I received were all $2000-3000 including parts and labor. I also googled the actual price for the water heater they claimed was $3850. Turns out it's listed online for $1000-1500. It became clear they were trying to price gouge me. When I sent pictures of the bids I had received to Supreme and told them they were trying to rip me off, he sent a receipt he claimed was for the heater showing they paid $2k for it. Which, while more than google suggested, was still half what they initially claimed the price was. I told them I wasn't going to pay the $4k which I had never agreed to, and which was clearly unreasonable, but that they could keep the money if they returned the first $1000 item. That means I have so far already paid them $5000 for something other companies agreed would be half that. This is where things have gotten bad. They've been texting me, calling me, and showing up at my house harassing me to pay them. I was sent a picture by one one of the twins of him and his daughter in an attempt to guilt me. He made up a story about promising his daughter they'd pay rent this month. He asked if he could come stay with me because "we have hot water." I have asked repeatedly for them to stop contacting me, and that if they believe they have a legitimate claim to have their attorney contact me. They have continued harassing me and my family instead. I've told them if they continue the harassment I will be forced to file a police report and that I am prepared to file a restraining order if necessary. I was very patient over the three weeks my family and I had no hot water, but price gouging and subsequent harassment is unacceptable. I've seen them respond to people here who complained about them by calling them liars. I'm not posting screenshots presently as I think it's unnecessary, but am happy to if it becomes an issue. Edit: They called me a liar, so I posted pictures. Avoid these people. Edit 2: They found me on twitter and are continuing to harass me there. Edit 3: This is the part they charged me $1000 for: https://www.supplyhouse.com/AO-Smith-100109424-White-Rodgers-Intellivent-Gas-Control-for-Natural-Gas-4-Manifold-Pressure-Setting-A1-72?gclid=EAIaIQobChMI5rnM7enC2gIVFNNkCh3cLQVlEAkYASABEgKDMfD_BwE Edit 4: https://www.shouselaw.com/cyberstalking.html read more

I was coming from a place of desperation when I called these guys-- the a/c had stopped working during the worst heat wave of the year. My regular company was booked two weeks out and I wanted someone, anyone, to come out and have a look at it, hoping I wouldn't have to endure another night in a 90 degree room trying to sleep. Enter Akido (forgive me if I got your name wrong) from supreme. They tacked us on to the end of a long day, came out and when he left, I had a working a/c and an education on other steps I could take to make my system more efficient. So knowledgeable,personable, hard working, honest and cool. Thank you so much!!! read more

Reliable and trustworthy. Firstly I'm not someone who post reviews, but for them I had to take this time out. I've used their svcs twice from last yr and this, and both times I've had nothing but a positive experience. As a 1st time home owner, there are so many things that I didn't know, but both times I called them, once for plumbing and the other for heating, they not only fixed the issue, but also explained the process throughout for my knowledge. That's what I loved about them. From initial inquiry response time to setting appointments, to coming by on time and finally getting work done, they are very professional and precise with their work. read more

Same day replacement of water heater completed within 3 hours of request. They left my property in better condition than when they arrived. Heat access was on the side of the house and the work completed in the rain. Hire these guys if you want it done right. read more

I previously used these guys to repair an old wall heater. A little pricey, but they got the job done. Fast forward to January 2020, and the repairman, John, tried some pretty shady tactics to extort money from me. I scheduled an appointment for them to stop by a unit to fix a brand new wall heater -- barely 1 year old. I confirmed with John over the phone that if there was a repair, that they take credit cards and could email me an invoice since I couldn't be there. He said no problem. John didn't do any repairs when he stopped by the unit, but said that problem was a faulty gas valve. He didn't know how much the part was, and said he needed to look it up. What I didn't know at the time, is that he REMOVED the part from my wall heater (a HUGE part), and then he used that part to hold it hostage to try to extort a "trip charge" which he never disclosed up front. He tried to charge me $650 for the repair, telling me how the part is expensive. It turns out the part only cost $90 -- since I had another heater guy repair the unit after he tried to extort money from me. See attached pics of our text conversation, where he tells me he won't return the part unless I give him money for a trip charge he invented after the fact, when I told him that $650 seemed pretty high to repair a brand new wall heater. Then he drops off the part without reinstalling it after I refused to let him extort money from me. I got another wall heater guy to replace the part (which cost $90). Total cost was $270, including the part. I'm not trying to promote another heating repair company, so I won't list the name of the company that actually completed the repair for a reasonable amount. But what this guy did, representing Supreme Heating & Plumbing, was highway robbery and theft. read more

Very disappointed with this company. They were assigned to us by my home warranty. We were not getting any cool air from our brand new ac unit and they figured the breaker was tripped. They reset the breaker and left right away without any further diagnosis. After they left we found the breaker kept tripping every couple of hours so we called them back and they said to go thru the home warranty again. A rude lady who answers their phones said they can't come out before a week because they did what they had to do and the warranty company needs to process the paperwork. The home warranty said the technician hadn't turned in the paperwork which was after 5 days of his visit and they had to wait to redispatch them. After multiple calls and texts, Supreme said they could not come out and also could not give me a timeframe on when they might be able to. I resorted to paying out of pocket to get repairs done. Horrible customer service, and staff doesn't know what they are doing! Stay away!! read more

I WIIL NOW BE USING SUPREME P&H FOR ALL OF MY HVAC AND PLUMBING NEEDS! Their workers are all top of the line and their prices were super affordable. They know what they're doing and they were in and out! Quick, professional and knowledgeable, what more can you ask for? I messaged them regarding an old wall furnace removal and new furnace installation and they called me back immediately. Their workers were able to come out the next day and get the job done! When its 30 degrees in the Bay Area and you're able to get a company to come out and serve your needs in less than 24 hours, that says a lot! Supreme made it easy to pay online and gave me a detailed, professional invoice-- not to mention they beat everyone else's prices by a landslide! I would highly recommend them to anyone! read more

Horrible customer service, was charged extra for relighting pilot light, I guess it wasn't covered under service call and minor repair.... They also went ahead and perform service without authorization. So the 85 for service call basically covers them to show up... don't be surprised for additional charges without authorization read more

Supreme Plumbing & Heating - Bill that was charged without approval - Heating & Air Conditioning/HVAC Near Me - Oakland, California

I've been using them to help with an old rooftop ac and heating unit. First the heating system failed and they were able to troubleshoot and find a solution, then came summer and the ac unit needs to be replaced which they're also handling (no small job considering we need to rent a crane to even get the new unit up there). I've appreciated their responsiveness throughout and their skill at working with this outdated unit, I had been trying to find someone to help me with this system for awhile so I'm happy I found them! read more

Always reliable service. We've used Supreme several times in the last couple years and I absolutely owe them this review. The Bay has been hit with a cold snap, the holidays are here, so fixing a heater is a necessity. While every heating business has been overwhelmed and busy, Supreme squeezed us in to repair our heating unit. Great and professional service, we are so grateful. Here's to a literal warm Christmas gift--just in time. Thank you! read more

Awesome. Had a pilot let that went out and was trying many times to get it on, without blowing myself up. These guys showed up super kind, professional and efficient and solved the issue. Also told me that the main gas line feeding into the Williams wall heater won't open until the pilot light is on, so I don't have to worry about a future explosion. A win for everyone! Thank you for the speedy work today! Called near noon and had an appt close to 4pm :) read more

I found this company through NETWORX. I'm so glad I did. They came out on very short notice "same day within 4 hours, they came to my home." They replaced a valve in my older furnace, a part had to be ordered. They came out the next day and replaced it. They were eager to give information on how to save money when making repairs to your furnace, which I appreciated very much. The repairs were made in a timely manner the furnace was cleaned and checked for gas leaks after the work was completed. read more

I have used these guys 3 times now - excellent service and very knowledgeable. These guys have earned my business, for any HVAC plumbing needs, I'm calling Akida and his brother. Exactly what I'm looking for in an plumber/HVAC company. Highly recommended. read more

A couple of years ago, our heater stopped working in mid Nov. I called them and they arrived within a few hours. While they were here they were kind and explained everything they did. I had such a good impression, I called them again when we wanted to add a register to an unventilated room. They are honest, trustworthy, kind, and knowledgeable. Cannot say enough good about them and their company. read more

Avoid Supreme Plumbing if you have a complicated system. We called them because our system was down, we had no hot water or heating in our house, and they were very responsive and had strong yelp reviews, and they said on the phone they did hydronic systems and would figure it out. They charged us $1,000 to replace a part we later learned was never broken, and then quoted us several thousand to completely overhaul our system, and told us they wouldn't be able to schedule it for over a week (while we had no hot water or heating!). We ended up calling East Bay Hydronics (strongly recommend!), who spent a few hours, figured it all out, and charged us a few hundred dollars to replace a couple small parts and fix everything. Supreme Plumbing are not bad guys, but they were in over their head on our repair, and instead of admitting they couldn't figure out what the problem was, they were just shooting in the dark at our expense. read more

I called them with an emergency burst pipe and they sent two technicians within 10 minutes, they leapt into action and resolved the problem quickly and effectively. Great team. read more

The guys at Supreme are super helpful! They helped me troubleshoot a problem over the phone that fixed my furnace without even coming out or charging me a fee, these folks know their stuff and are helpful and professional. I will definitely reach out to them again if I have an issue as they are knowledgeable and trustworthy. read more

I had an issue with my upstairs furnace and called Supreme. Akita came by and did an excellent job diagnosing the issue. He noticed my furnace blower was not working because the control board was burnt out. So he said the diagnosis was $85 but with the new control board (which should be about $200 - $300 he said) the total installation and diagnosis fee would be $225. So all in I thought $500 and was OK with that. He then sent me an invoice from Johnstone Supply in Oakland for an ICM2807 Control Board which was $573 with tax. I thought this was real high so checked on Amazon and found it for $160. Akita told me he would not install any online items because they were not guaranteed so I said I would buy it and install it myself because that price difference was just too high. Akita called me back and said he changed his mind and would install it. So the unit came and Akita came over and attempted to install it. It was the wrong unit. What I really needed was the ICM282A which apparently Johnstone Supply knew but put the wrong item number on the invoice. In retrospect I think this is a total scam and they do that so people can't buy THE RIGHT and perfectly good unit from Amazon. So I returned the ICM2807 for free on Amazon and ordered the ICM282A for $121. I ordered it Prime 2 Day and it showed up in 5 days and Amazon gave it to me for FREE!!! I couldn't believe this and that's why I love everything about Amazon. I was pissed the invoice had the wrong part number on it and Akita said "I didn't tell you to order that one." I said "c'mon man - it was on the invoice and I didn't feel I had to check your and Johnstone Supply's work as you are the experts." That was our only disagreement but I agreed to pay Akita for the second visit which was a waste of my time. Rather than setting up an appointment with Akita again I just installed it myself and paid Akita $185 for his time. So I spent $185 and have a perfectly working furnace instead of spending $800. I'm giving Akita 4 stars because he absolutely knows what he is doing but I really didn't like the quote and the wrong invoice - even Berkeley Supply had this unit for $299. Somebody is ripping somebody off. read more

I didn't know they did appliances, so I'm happy I actually bumped into the Brothers at Home Depot and inquired about their services. My kitchen stove has been out for about 1 week and they quickly diagnosed the problem. Contacted me for an available time, came by during the evening hours, and within 3 days, the part was ordered, and my wife was happy she could use our stove again. Fair price and easy to communicate. read more

Heaters always fail when it gets cold and when everyone is busy. One company I called quoted a service call 8-days later. Most were just busy. Luckily, Supreme Plumbing & Heating had a slot a 5:30 p.m. that day and Akida Harrison came by. With heaters, you don't know if it's a $300 or $3,000 bill so luckily it wasn't on the lower-end of that scale. Akida was able to replace a worn out igniter and we were able to have a warm Thanksgiving. Fast, courteous and friendly service during this time of year is hard to find so definitely consider Supreme Plumbing and Akida as a high-recommend. read more

I've had a broken boiler for a year now, and these folks showed up and fixed it no problem! I should have called them sooner . They show up on-time, with no surprise bills. They were able to diagnose an electrical problem with my boiler (it wasn't a plumbing issue) and fix it within an hour. Will be using them again! read more

Supreme has been my go to furnace people for the last several repairs I had to make for my units. It's never a fun thing needing them but when I do they are there and they get the job done for me. Harrison is very professional and help me quite a bit so I highly recommend them. Thanks so much for everything read more

Amili did a number of things that will make me continue using his excellent services. First: he answered the phone! This may seem like a small thing, but to me it's important. Secondly: he came on time! Another plus. Thirdly: he was nice to my dog (okay. Maybe not that important, but it shows what kind of guy he is) and Fourth: he swiftly (cane the next morning) and expertly fixed my heater. A great transaction and easy. Thank you! Addendum: just had a little glitch with the wiring after the fact, and I not only got Amili, but his brother too. In two seconds flat we were warm again. One more plus to their services. They stand behind their work!! read more

Amili is now my go-to HVAC pro! I ran into issues during my Nest thermostat install and he was the only one who answered the phone on a weekend. He was nice enough to help diagnose the issue over the phone and had I been a bit more observant about my furnace setup, it's likely he would have found the problem remotely. Since I'm such a luddite, Amili made a weekend housecall (brilliant!) and found my issue quickly. He was super-patient with me, explaining what was going on and how to troubleshoot in the future. My AC and furnace are back up and running, Nest is fully functional, and I didn't have to break the bank. Thanks, Amili! read more

If you need an expert who's quick, professional, and does an excellent job, look no further. I love these guys! We needed a Nest Pro to fix problems with a short cycling thermostat/furnace. and I was referred to Supreme by Nest, along with 4 other local shops. I'm thrilled that I chose Supreme. I had a phone consultation with Amili to discuss what was happening. Then, Amili and Akita both came to our home to scope out the problem and offer suggestions -- all before even a dime was charged. We went from popsicles to balmy within 36 hours (during a very busy heating season). They helped me get heat back on in our home, and even were able to add control of additional functions our HVAC was capable of that we weren't even aware of! Well worth the visit. Last, I can't overstate how friendly, polite, and accommodating Amili was. Truly a gentleman, and I'm pleased to have met him. read more

My heater stopped working in January 2022 in my new home and my Nest connected me to these amazing brother Duo! (Thank you Google). They came, inspected, recommended filter replacements, thoroughly explained what the issue was and boom, my house was heating up again. They are friendly, welcoming, fast and careful and overall the kind of people you keep close in case any heating or plumbing issues come up in your home. They will be my go to people for all things heating and plumbing! read more

I had a problem with my thermostat and attempted to replace it on my own. After a couple of failed attempts, I called this company and spoke to Amili. I told him my heater was fine but would not respond to the thermostat; he asked me a couple of questions, then offered to walk me through a simple test to determine whether or not the thermostat was indeed the problem. Turns out I was buying thermostats that are not compatible with my heating unit. For someone to be knowledgeable enough to walk me through a diagnostic based on my mumbo jumbo and actually provide a simple solution without costing me $150 is a big deal. I will certainly feel comfortable giving them my business in the future. read more

Prompt, patient, courteous and knowledgeable. Mr. Harrison walked me through fixing my water heater pilot light over the phone. He succeeded where my online DIY research fell short. Much appreciated! read more
