Recommended Customer Reviews

Great service, even on the Labor Day Weekend! Perry came to our house in Sunnyvale within an hour of our call on 9-6-2015. He quickly drained the old, leaking water heater onto our thirsty grass then removed it; he then installed a new floor in our water-heater closet which is accessed by a door outside the house. Last, he installed a 40-gallon American Standard water heater that he brought with him. Great service, great attitude and from what we saw when we comparison shopped, a GREAT deal.

Best company for your plumbing, heating and air conditioning needs. When out of town recently, we had an unexpected leak. My teenager did not know what to do. We called ATC from Hawaii and Tim agreed to go to our home immediately. He diagnosed the problem, stopped the leak, helped my teenager clean up the water and came back the next morning to fix the problem permanently. It was comforting to know that there is a company out there who understood our concerns as both homeowners and parents. Tim spoke with us on the phone multiple times to reassure us that everything was okay. I would recommend Tim to anyone for his knowledge, his responsive, and his fair pricing.

Everytime this company has sent us Plumbers they have always been very nice, friendly and quick. The most impressive thing I have experienced is their honesty, multiple times the plumbers have gone out of their way to explain the most affordable way to fix our issues. I have always felt they treated us with respect and care, I would recommend them to anyone.

Ditto on the nice guys comment from the previous review. I had a leak and had them come out on Saturday. The plumber did a great job and within a reasonable time, even though it was during their more expensive time period. He also said nice things about the owner - that he is nice to his plumbers - let's him attend his son's kindergarten graduation! I would recommend ATC - experienced plumber & nice company with great values!

Last week our water heater stopped working. We followed our landlord's advice and called Around the Clock. They scheduled a 9AM appointment, then called and said it would be between ten AM and noon. A young man finally arrived about 1 PM. He took a look and estimated that the air intake was clogged with dust. He vacuumed the heater closet and relit the pilot, and everything appeared to be working fine.
He was cleaning up when his office called to check in with him and he went outdoors to take the call. When he returned, he called the landlord and informed her she would need to buy a new water heater and pay them to replace it. When she questioned the need, he tried to persuade her on the basis that the heater was getting old. First, it's not that old; second, that has nothing to do with the problem.
When your car runs out of gas, do you buy a new one?

Since my first experience with ATC, they have been our go-to source for fixing leaks, replacing toilets, and even a rather extensive backyard project involving permitted water and natural gas extensions. Always stood by their work, issues if any are resolved. Worked very well with city inspectors. Not the cheapest, but definitely not the most expensive either. A happy long-term customer.

We have used ATC many times over the years and have always had outstanding service. Highly recommended.

ATC gave us a bid to replace our water heater, install a new kitchen faucet and fix a toilet leak. They showed up a couple hours late They installed the new water heater and got half way through the kitchen faucet, leaving us with a leaky fitting, and then left. They said they would get back to us later about finishing the job. They said the office would contact us. No word back, ever. The sales guy is very charming, but their work was really poor. Never again!!!

Pathetic service and attitude. Their plumber didn't fix the problem and instead charged me for full one hour. I have clarified before calling him that I won't pay for inspection, to which he had boasted that when they come they fix the problem.
I won't recommend them.

I've tried using ATC a couple times now. The first time was to try to find the source of a leak in my ceiling from the bathroom. They weren't able to find the leak, charged me for a whole hour and left a rebate form for toilet upgrades. I ended up finding the leak later and fixing it myself.
The second time I tried using them was to install new toilets using the rebate program they told me about. They gave me a 2 hr window, but almost didn't make it. I had to call the office to confirm that someone was still coming, and that's when they sent three people to try to arrive within the last minutes of the window. Two of the three people arrived, and they discovered that I had chosen the wrong sized toilets. I was lucky that they caught it before they started the work, but they charged me two half hours for the plumbers to arrive and leave. They agreed to reschedule for the following week, which is when I promptly stopped hearing from them.
After waiting at least one business day, I called them to confirm my rescheduled time. They were closed (so much for ""Around The Clock Services"") and asked me to call the next day. So the next day, I called, and they said yes it was in fact scheduled -- but no one had given me a window for when they would show up.
Finally on the rescheduled day, a single plumber arrived. He arrived roughly on time, and finished the job in a little over an hour. He cleaned up, went outside for over half an hour and then charged me for two hours of work.
Overall while they are knowledgeable, the quality of their work is average and their customer service is lousy. If you decide to use them, expect to pay for twice the time they provide; and be prepared to do most of the communication yourself for confirming apppintments, window times, and arrivals.
