Competitive pricing and they did a stellar tankless water heater installation job in a timely manner. Could not recommend them more!

Customer service from this company is extremely poor. Call backs never accrued after leaving our number THREE times. Just has himself trying to do the job of three. Absolutely no repair service on items they have already installed over two years. If they install a waterless Tank, they will not give you any quick time to repair what he installed. read more

Heard them do install a couple of toilets, deal with a shower valve I was having issues with, as well as a backed up drain. Was extremely happy with the entire process. Great communication, The work was done well and the place was kept clean. Fair price as well. Would use again and recommend. read more

My tankless installation was a little more complicated than most. I called a few plumbers, and one of them told me that he does them if they are straight forward, but he said the guy to call for tankless is Roy at Conejo Tankless. I had already left a message for Roy so felt comfortable. As the old saying goes, "You get what you pay for". Roy wasn't the cheapest, but his price was fair. 70% of his business is tankless water heaters, so how can you go wrong. 5 days after the installation, I smelled a very faint smell of gas. I texted Roy and he was over within 30 minutes to correct a very minor problem. Will use Roy for all my other plumbing stuff. Thanks Roy!!! read more

Roy did a great job installing our Noritz tankless Water heater. He was fast, efficient and very clean. I'd definitely recommend him to family and friends. We love supporting local businesses and would use him in a heartbeat again. read more

Very overpriced. Took a rebate from my tankless water heater, and never told me. Installed a bladder a few months ago, came back, said it was bad, and charged me again for it? No more for me, thanks. read more

fast response, great job. Roy found why tankless water heater is not running and fixed it.

Roy did an outstanding job installing our new tankless water heater in a timely manner at a good price.

I wanted to replace my existing water heater with a tankless and have hot water to the kitchen sink faster (farthest from the heater). Roy came out and look over my existing setup and suggested the Noritz. After it came in he set up an appointment and was there on-time, a real plus in my book. The first day was doing all the prep work and the second day was putting in the new heater. Roy did an excellent job and he communicates. I would highly recommend Roy to anyone needing plumbing services and if I need any in the future I will use him. read more

I had a tankless water heater problem for several weeks now. Suddenly my hot water output decreased to a luke warm water output. I have had this heater for about six years never experiencing problems. I've narrowed the problem down to the water valve after reading forums and the Bosch website. I ordered a rebuild kit and called Roy. Roy told me that he had never worked on Bosch units before, but was willing to do the job and gave me an estimate and an appointment. On morning of the day of appointment he called and had to cancel because his other job ran long. We rescheduled but I couldn't take time off again until two weeks from that day. Two more weeks of luke warm showers in this cold weather.. I ordered a complete water valve and while waiting I attempted to exchange the water valve myself. It's not brain surgery. I had a problem removing two last set screws which had become frozen into the brass water valve, the phillips head stripped. The screws weren't flush with the valve. When Roy and I talked the day prior to the appointment I told him about that. He sounded confident. When he came over, he briefly attempted to remove the screws while on phone with tech support. He wasn't excited about Bosch units nor about servicing tankless water heaters. He seemed helpless. Tech support basically said a new gas valve would have to be ordered if the screws aren't coming out. Roy didn't charge me since he couldn't remove the screws but there wasn't a whole lot of brain storming going on and not a whole lot of motivation noted. I think I basically just wasted two days off and two weeks waiting around. I'm sure on new unit installations he's a completely different person, but for servicing tankless units .".Meh, I've experienced better." read more

I was in need of a new water heater and researched tankless units to ensure it could accommodate the size of our house (4,600 sf). Based on recommendations, I went with Roy at Conejo Tankless. Roy was very professional, friendly and provided his years of knowledge confirming we could use a tankless unit. After discussing the Noritz and Rinnai units, we went with the Rinnai unit with the wifi capabilities so we could control the unit from our phones. Roy walked us through the installation process and what would take place along with an estimate. The day of the install Roy was on time and it took 8 hours to complete. He didn't leave until we fully understood how the new system worked. He even returned a week later as I had concerns over an item that turned out to be a non-issue. I highly recommend Roy and Conejo Tankless. You will receive professional and honest service with great communication from him. Thanks Roy! read more

Roy is the best, he's always courteous, on time and a clean worker. He makes good suggestions and his prices are great and competitive. Most importantly, Roy is dependable, you can always count on him. read more

Great work and installation from Roy ... really pleased with how we discussed the installation options and then the final installation.

I can't say enough good things about my experience with Roy at Conejo Tankless Water Heater. He was able to solve our problem with our tankless within minutes and took take care of a few other plumbing issues we had. He is very knowledgeable and I would highly recommend him if your looking for an excellent plumber. read more

Update: It has been over 4 years, and while lots of other upgrades to our home have had a problem or two, our tankless heater, installed by Roy, is still running smoothly. No leaks, no outages - just great! Thanks again for improving our home! read more

Roy is a class act and did a great job cleaning and getting our tankless water heater up and running. Would highly recommend him.

Roy came out and replaced a check valve on my tankless water heater and cleaned out what was apparently an extremely filthy filter. Although I had an initial problem I was able to fix one my own, I got the run around with other tankless water heater repair companies, one that even tried to tell me that my neutralizer was an accessory unit to my tankless, even after having the panel off and the manual in front of me. Roy was able to diagnose the problem with my explanation over the phone, and came out and got my water heater, working properly for the first time since we moved in, quickly. Would call him for future water heater needs and plumbing. read more

Roy was AMAZING!!!!! He was super friendly, professional, prompt and thorough. He was very responsive whenever I called. He explained his work and helped me understand everything he was doing . Above all he did an excellent job and his prices were very fair. Roy is an awesome guy and I will definitely use him again and highly recommend him. read more

Not reliable and very unprofessional. Did not call back when promised to schedule an appointment, but had decided to give another chance. When he arrived for installation (on-time) my 9 year-old daughter had answered the door and said I was sleeping. Instead of asking her to get me (I was upstairs doing laundry and did not hear the door), he left. Who doesn't ask for a parent when a child answers the door? When I called him, he refused to return and was very rude. He said, "He wasted enough of his time and that I should go with the other quote I had received". Although I had called thirty minutes after I realized he was running late, he claimed he had wasted 2 hours of his time and lost money on the job. Beware. read more

This is an amazing company run by a guy named Roy Madigan. Roy installed our tankless water heater in 2008 and we have not had a day of trouble with it. It has been the simple most important decision that we made for our daily lives. Everyone in the house, every single day, can take as long of a shower as they want. Ten people in a row could take an hour long shower with no problems. Roy does an excellent installation and is available and friendly in answering questions. I went out of my way to write this review because it is Christmas, four years later, and I felt I should give credit to someone who made life so much better for us. read more

Why didn't we get a tankless hot water heater sooner? Though we have since moved out of state, Roy Madigan sold us and installed our tankless water heater and we were delighted with the always-on hot water, the dependable service and working with a locally-owned business. read more

Roy is amazing and trustworthy! I was out of town when I heard that my hot water heater stopped working, as well as the garbage disposal. Roy fixed the garbage disposal and installed a new hot water heater for me. He is affordable, dependable, and does an excellent job. I highly recommend him. read more

Maybe if Roy shows up, he's a good plumber, but that is only if he shows up. He never answers the phone and after leaving a voicemail, you may, if you're lucky, get a call back a few days later. Twice I scheduled him to do work at our house and we agreed on a day and time and twice he called right before the work was to be done and cancelled. Save yourself a headache and find a different plumber. read more

I didn't know anything about hot water heaters and Roy was a patient and thorough plumber who made sure I understood the technology. And the install was quick and painless. Oh and he also fixed a bunch of other things in my house while he was there! Would highly recommend. read more

I recommend this company to anybody thinking of putting in a tankless water heater. I got multiple quotes and this one was the cheapest. Roy is friendly, prompt, and does great work. The job was done quick and clean. Being a local business person who lives in the community is also a plus for me. read more

We couldn't be happier with our decision to switch to a tankless water heater, or with or decision to have Roy install it. He was professional, reasonable compared to other quotes, and very attentive to detail. He clearly takes pride in his work. read more

We had a toilet come loose and Roy came out and fixed it. He had to replace the ring and replace the wax and seal. He did the job in a very efficient and professional manner. The price was also very reasonable. Roy also installed our tankless hot water system. We cannot be happier how it has worked out. We would highly recommend Roy and Conejo Tankless for your plumbing needs. read more

Roy is a plumbing genius!! He fixed my sink in two minutes after two other plumbers completely missed the problem !

Roy is outstanding. He's honest, professional and reasonably priced. He does great work with little to no disruption to your house. Nice person as well. read more

Roy is a nice guy and I've used him a few times to service my hot water heater without any problem. I recently used his services to install 2 new toilets and a new faucet in my home and was quoted around $250 to get that work done. I was away when he installed everything and he left a bill on my counter for almost $600. Additionally, one of the toilets leaked and caused damage to my new wood flooring due to it being installed improperly. When I asked Roy about the higher than expected charges he said that the toilets were more difficult to install than he anticipated (because they were top button flushing units). He stated that he chose to charge me on an hourly basis and included his time for breaking down and throwing away the boxes the toilets came in. After e-mailing back and forth he told me to just pay what I thought I owed him. He is refusing to return to fix the situation and I now have to hire another plumber to literally clean up his mess. As I said he's a nice guy and I have been a loyal customer of for a few years. I think how people treat customers when there is a problem speaks volumes about their honesty and integrity. I will not be using Roy again. read more

If you want an HONEST, KNOWLEDGEABLE plumber, Roy at Conejo Tankless Water Heaters is the man for you. I disagree with some of the comments below about lack of returning calls. ROY ALWAYS RETURNS CALLS and will always do a great job at a fair price. WE LOVE HIM, Don't even think of calling anyone else for tankless or general plumbing issues. read more

The people giving Roy 1 star reviews are crazy. I've had Roy out to our house several times in the last 2 years. Every single time, he was on time and did what he said he would do for the price he said it would cost. He cleans up everything, you won't even know he was there. We had chronic issues with a hot water heater installed by another plumber. With Roy's help we were finally able to get the problem fixed. read more

Very professional . great service . used him in the past cuople years ago and called him again .

Couldn't be happier - my wife now has her hot water back! Old talkless, a Bosch, died. Various reps wanted up to a thousand dollars to install a unit I bought at Lowes - on sale. Roy came out, installed in in a few minutes, charged $200 and made us a happy family again. Also, while he was here, he checked out the water flow for the main shower, found some problems and repaired it for free! I am one happy customer read more

Couldn't be happier with the service. We had an old Bosch which gave up. My wife found a tankless on sale at Lowes. We called around for quotes - they ran everywhere from $250 to over $1000 to install our unit. Some people did not know how to handle the installation, but weaned to charge us anyway. Roy came out, matched the lowest price, adding in some new gas lines and even repaired a problem we had in our shower for the single price. Great service. I would recommend him and I will use him again. read more

It has almost been two years since my tankless water heater installation. All the concerns I had never materialized. I have never had a problem with my Noritz unit. No leaks, no noise. No pilots blowing out. No noisy rumbling like I had with my old water heater. I am able to run my front loading HE washer with no filling problems and no problems running my dishwasher. I have much more space in my utility room and can do my laundry without squeezing between my dryer and the old bulky water heater. Mr. Madigan did a great job. He arrived and completed the job just as he said he would. He never tried to add a "this" or a "that" to his price after he started the job and he actually did a few extra things at no extra cost just to reassure me. My only problem now is getting my teenager out of the shower in the morning since we no longer run out of hot water! -The Minguez Family read more

I've had plumbers at my house before and the experience always left me with a very bad taste in my mouth. Wow! Roy was there when we needed him most. Prompt, polite, honest and extremely knowledgeable! This guy knows his profession inside and out. I wouldn't ever think of calling another plumber. As long as Roy is in business, he's got me as a customer!!! read more
