Recommended Customer Reviews

UGH woke up to sitting water in both showers and the toilets wouldn't go down. Called these guys from a referral and Vince came quickly. He assessed the issue, climbed up on the roof and snaked it quickly. He was thorough, friendly, fast, and explained everything. Hopefully I won't need them again anytime soon, but if I do, I know I'll be well-taken care of.

I wish I could give a positive review but the technician that called me was so rude. I originally was working with someone to setup an appointment and they were really friendly. I explained the situation that we had no heat the last couple days on the weekend and that since it was in the 30s in the mountains, it was about 50 degrees in the house. They mentioned the soonest they could get was in a few days and I told them I would try to get someone before if possible and they mentioned they understood and asked to let me know if I got it fixed.
That being said, I'm on a business trip in another time zone and had called several other places where I had lost the number and tried to call the back after Saturn helped us at the last minute (they're amazing and honest!). In the middle of a deployment at work, a technician calls and I try to explain to them but they treated me like I was some sort of villain when this is a few hours before the appointment and just hung up on me talking in an amazingly rude tone. It was unbelievable. There wasn't any response like we're happy you have heat now or please in the future if you could give a sooner notice or we hope we have the opportunity to help you in the future or anything. I was treated so poorly that I will not give them a chance again after being hung up in the middle of the call while they scorned me on the other end. Very unprofessional.

Hired them to fix my hot water heater. Instead of doing that they tried to sell me a new one.

Nothing was draining (sink, tub, toilet) on a Saturday. I left messages for several businesses, finally talked with a human at one business who said they were ""booked until Tuesday"" and most businesses didn't even check their voicemail.
Starting to panic... I finally called Around the Clock. TJ answered the phone, listened to my problem and did some diagnosis over the phone. When I asked about rate he told me upfront the hourly rate plus warned there would be a machine charge. He was able to come out within the hour (!!) and cleared out our problem.
Excellent communication - told us what was going on as he went along. Very personable.

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.
