Never, ever, ever call them for any reason. The person answering the phone has one job and it's to get you to hang up. He will lie and tell you they don't carry things you've bought there dozens of times before because he has no idea what you're talking about and doesn't care. They have amazing prices on some things and are full MSRP on others so shopping here is a total crapshoot. Generally speaking, commodity items like conduit fittings will be a bargain. Fancier things, like AFCI breakers, will be more expensive than Home Depot and they probably won't pull the right ones even if you show them the catalog page with all the numbers they could possibly need to know because they cannot read English any better than they speak it. They'll give you one price up front and then when they go to ring it up they'll realize they were wrong and give you a completely different--always much, much higher--price. It's rarely worth the frustration to drive out there unless you're already going out to buy fentanyl from one of the bums in front of the Amazon warehouse. read more

Just purchased a plumbing check valve from them. No fancy warehouse, just a great priced, working supply house.

Knowledgeable, experienced, hardworking, friendly and humble sales were so helpful! Keep moving forward American Ace Supply!

Don't ever come here. Asked the employees for help and they stared at me like I didn't speak cantonese or english. I would recommend any place other than this place. read more

I keep coming back here, the staff is very friendly and they have all the supplies that I've needed. If I need a length of pipe that they don't have, they can even make it for me on the spot. Can't speak highly enough of this place. read more

American Ace Supply - They will make custom lengths of pipe! - Hardware Stores Near Me - San Francisco, California

Most of the employees are Chinese. No one spoke Spanish. If you speak English, Cantonese or Mandarin, you're good. They should have a bilingual English and Spanish speaking employee. If you need plumbing pipes, joints and connector, this is the place to go to. It's not your average Ace Hardware store. read more

I called to ask for a water heater and they told me to come in person to see the options, I came in and they told me that they don't have anything in stock and have to order it for me. So I thought that I could have done it over the phone, why did I come? Then I gave them reference of what I need and they said they don't have it in stock, after they told me they would order it for me. Hardly speak any English, super rude and unprofessional. Never come here! read more

Extremely expensive and terrible customer service. There are like 20 employees there and somehow it's still hard to ask a question.

This place is a hidden gem!!!! What you get: quotes for branded plumbing and fixtures at about 50% off retail prices. no joke. service is FAST. they will even special order for you. i have picked up items here in the past and am now spending a boatload for our remodel. guaranteed they will always quote the lowest price in the bay. What you will NOT get: friendly customer service. well, i shouldn't say that. it depends on who you are working with. i always call to get a quote and they have always been nice. at the store not everyone speaks english. they will not hold your hand. have in mind what you want before you go in. otherwise you will just be given a big catalog to shop out of (which is fine too. my hubby stopped by with a picture of a faucethe wanted. they handed him a catalog and he found exactly what we needed at a very very reasonable price), they cater to contractors but are happy to give the same low price to everyone. read more

I would have liked to have given this place 5 stars because I was able to buy two Grohe plumbing fixtures at half off list price for my remodeling project. However, when my contractor installed the one for the kitchen, he said the nozzle pullout hose was missing. I don't know whose fault it is because unfortunately the contents were not checked during purchase. I ended up having to pay $20 for another one, though to the store's partial credit they opened up another box and took one out. I decided to pay to appease everybody. At least I got what I wanted at Amazon.com prices without having to order it online. It's also better than what I got quoted at certain kitchen and bath fixture stores in the Sunset. Also, don't expect great friendly service because the people running the place obviously talk with typical mainland China attitudes. read more

Got a ton of cast iron pipes and stuff and saved over 50% compared to Lowes...service was fast and friendly today (maybe cause CNY is just around the corner) They take Visa and Mastercard only. Returns are accepted provided item is not used. No issues with returns. read more

Ordered most of my supplies from the San Jose location and they were helpful. It's a warehouse, and you pay low prices so don't expect full-service. They didn't have the showerhead I wanted, but took apart a set and sold me the showerhead by itself for the right price. My local store sold it for $45, I got it here for $31.50. List price is $62 and online stores sold for about $35. Helpful, quick and knowledgable. One star off because I showed up at 7:30am and they were not open even though their listed hours is 7am. I had to go back during my lunch hour to purchase what I needed. I am impressed with what they have in stock though. No one else I called had what I was looking for right away. read more

This place is a freaking mess. A tone of employees running around bumping into each other. They don't give a crap about customer service! Don't ever spen a nickel here read more

Oh my, this place is far out! It's as grimy of a warehouse as you could imagine, with a big counter area manned by some CHINESE guys. Learn to understand their dialect and you will land yourself quite a bargain, no doubt! But it's the omazing selection which makes this place truly cool. Where else are you going to find Federal Pacific 40a 2pole breakers? Let alone both thin and standard sizes???? and for $40 dollars????????? Tons of other things that you might think you would have to order online to avoid paying a fortune can be found here. It's not for your typcial home depot or lowes customer. stay away if you don't know what you need specifically. Otherwise, feast at the bounty that is American Ace Supply Inc Electrical Plumbing! read more

This place might be hidden, but it is no gem. My daughter and I walked in looking for some items and we both almost got ran over by people rushing around with carts and dolly. I was trying to ask a question and there were 3 people behind the counter looking at me. The First one came up and and shook his head back and to say what? I continued I continued with my question and he looked at me like he did not understand saying something in Mandarin I think and walked off? The next two guys came up specking Mandarin I think and then proceeded to just say No, No go away? So I say No, No stay away from this place! read more

great shop for home remodeling electrical needs. bought an entire house worth of halo leds for cheap here.

This place has the best prices - hands down. Douglas rocks and is super knowledgeable. He can get any plumbing or lighting supply product that I need. read more

This is one of my favorite supply houses here in the city and they always have what I need when it comes to plumbing supplies. It's true that most of these guys don't speak English too well so you just have to be able to tell them or show them exactly what you need. read more

cheap place and they only speak Chinese. Come at your own discretion but things are cheaper here compared to Lowes. You need to bring your bag of courage since it feels like a Chinese market in the morning. read more

Best prices I've found, but speaking a little Mandarin would help. Great selection, they will cut and thread pipe. They are busy for good reason! read more
