Best Tankless Water Heaters in Glendale AZ

Thank you GERALD S!

Excellent service and appreciate the pointers on using our garbage disposal.

I was extremely satisfied and impressed with the service I received from One Shot Services. Gabriel responded quickly and was very knowledgeable in identifying and repairing the issue I was having with the GFCI outlet (consistently shorting out) on my pool pump electrical box. I thought I was going to need to replace the entire box since the GFCI had already been replaced and the electrical box was 30+ years old. Gabriel is such an honest person and he almost insisted he troubleshoot before replacing the box. I'm glad I listened to him. Doing this, he saved me hundreds of dollars. His rate seemed fair and he will be the person I call the next time I need something out of my league done.

Eric was very competent and polite. I would recommend this company to anyone who wants a great plumber.
Our tenants were also very pleased with his work and professionalism.

I have referred Nicholas and brad with desert water to several of my pool service customers when they need help with plumbing, gas lines or water softeners. Every time they have shown up quickly and gotten the job done with my customer saying nothing but good things. If you need anything from new water softeners to new gas lines ran across you properly, or even little stuff like back flow valves replaced these guys really know their stuff!! Highly recommend

Orlando came out in the middle of the night on a Saturday all the way across the valley to fix my leaking pipe! He was amazing and I couldn't have called a more amazing plumber. These guys are the best and know there business. I highly recommend using them! You will not be disappointed. Great job Advantage Plumbing!

I had a reoccurring problem with backed up plumbing for a couple of months. Two companies came out before Simba Plumbing and were not able to fix the issue. Stefan used his camera and was able to detect that we had roots in our main line. He replaced the pipe and we haven't had any issues since. Really appreciate his hard work. Highly recommend.

They are always on time and friendly with great professionalism.. we will continue to use them for all our plumbing needs and we would highly recommend.

The technician was excellent, I chose not to get the work done because the price was ridiculously out of this world. They quoted me $1,565 and they said it would be about three-and-a-half to four hours of work, if you do the math that is approximately $375 an hour. Who the hell can afford that...

LOVE DiamondBack Plumbing!! They come out when they say they will, charge exactly what you’ve been told the charge will be and do an excellent job of whatever your needs were. They have been able to fix problems other plumbing companies couldn’t do for us.

They are ALWAYS our first company to call with any plumbing disasters.

Paul & the rest of American Discount Plumbing are amazing! I've used American Discount Plumbing for 3 different services & plumbing needs.

How I first found Paul was one of my two water heaters (tank type) started leaking. I wanted to switch to tankless type (which are more expensive than tank type) so I called about 10 plumbing companies, and had 10 come and give me bids. I was so surprised that for some of the bigger name companies, they actually send a salesperson, NOT a plumber to come give a bid. And of course their bids were 2-3x the smaller companies. Crazy! So the 2 big ones were out when they showed up with salespeople. Then I had 3 smaller plumbing companies come and give a bid, and Paul was the lowest of them all, while also seeming to know the most. He spent the most time checking everything needed, and I could tell he cares about quality. He also had everything ready to go on the truck, so I went with American Discount Plumbing for my first water heater replacement.

Because I liked Paul so much, I had him change the other tank type water heater over to tankless about 2 weeks later. And boy, did he work hard! He was super flexible with time, and worked until the job was completed every time, and the piping looks like a work of art!

Just today (Saturday!) I walked into a spare bedroom bathroom, and I found water on the floor. I didn't even bother calling anyone else, I just called American Discount Plumbing. Paul answered on the first ring, and he ran to the plumbing supply store (closing in 15 mins!) and grabbed a new toilet and headed to me immediately.

I rarely write reviews, but I wholeheartedly recommend Paul and the rest of American Discount Plumbing for any plumbing needs. Don't even bother calling those other big name places who send a salesperson to give you a bid. Just call Paul at American Discount Plumbing.

Installed new water softener. I highly recommend Apache!

Bobby Bales from PlumbPerfectAZ is such a great plumber. He recently installed a kitchen faucet, 2 bathroom faucets and 2 toilets for me. He was punctual and very polite. His prices are very competitive. I will never call another plumber. If you want a plumber that is honest, call Bobby from PlumbPerfectAZ.

Leo was professional and helped us ASAP when we were in a crisis. Highly recommend!

The Home Depot referred me to Delta Mechanical for the installation of our new garbage disposal and they did great 👍🏼 First Sveto Milanov arrived early and after installation cleaned up after himself. He was not talkative but answered my questions when asked. I will definitely use them again 👍🏼

Scott the owner is very professional, friendly and knowledgeable. Highly recommend.

Bad service they are an agency not an actual plumbing company. They take your phone number and give it to all the plumbing companies and you'll have your phone number blown up with calls.
