Doctor Piper, Inc.

I have used Dr Piper to install my Thermal Solar system. Malden was very knowledgeable about everything around the solar and how it works. He came with his crew and did the installation for only few days. Now I have free hot water and I am really happy with his service and professionalism. Highly recommended!

On the recommendation of a contractor, I hired these folks to repipe my house back in February 2011. They did an excellent job; the price was competitive, and unlike others they explained what they were doing and gave me options. A few weeks ago I had a leak in one wall and they came out, after 6 PM on a Friday, to open the wall and repair their work; as it turned out, an original part had failed, but even though it wasn’t under their warranty, they found a hard-​to-​find part, came out on a Saturday and replaced two fittings, all for nothing. I would recommend them for any job as hard, honest and smart workers.

system, and Dr piper Solar was the best. Their representative, Malden
explained how the system worked, and the approximate timetable for
installation. They installed a rather large system (44 panels) on our
home, and it has been performing very well. It has been several
months, and we are very pleased with the performance.

I always think I have the right person on the job when they tell me I don’t need to do a repair or maintenance (even though the manufacturer says I do) and explains to me why I shouldn’t or should do this or that. Malden Maldenov is that guy. He also explained to me some trouble shooting I can do to determine certain things having to do with my Noritz Tankless Water Heater. He’s great. I am highly satisfied and will call him next year for our annual maintenance.

We bought a Bosch tankless water heater that didn’t work from day 1. We contacted Dr. Piper Plumbing since they are a Bosch certified installer. The technician came and checked the installation and agreed everything was done to specification. He finally got the unit to work. We paid them the service charge $ 125 hoping to be reimbursed that amount from Bosch. The technician indicated on the invoice that the installation was done right and he found no major problem with the unit. When I called Bosch service department to inquire about my service charge reimbursement, the idiot put me on hold and called Dr. Piper. He returned about 20 minutes later and said that Dr. Piper said the problem was caused by improper installation and that I would have to eat the cost.
In less than 30 days after Dr. Piper serviced the unit, it failed again. I called Dr. Piper to have them check the unit again to make sure the unit is not defective. The jerk told me I would have to pay another (new amount) $ 150 for him to come out again. That is when I talked to the good folks at Lowe’s. They paid for a service call to my place. And it was determined that the unit was a piece of junk. Lowe’s promptly refunded the purchase price + the service charge. I replaced the Bosch piece of trash with a Rheem and couldn’t be happier. As for Dr. Piper, don’t waste your money or time with these rip off artists.

We had Dr. Piper install our tankless water heater, and while that has been going well. When we needed them to come to check on it because it wasn’t working, they wouldn’t return calls. We waited all day for them to get back to us. So, they may be okay for installation, but you may be out of hot water for a few days if something goes wrong. We ended up going with someone else.

I had a terrific experience with Dr Piper. Unlike a couple of other plumbers I was trying to get tankless water heater quotes from, the guys at Dr Piper arrived when they said they would, did a thorough job (and even fixed my ski rack mounted across the garage from the water heater!), and communicated everything they should have regarding the installation and operation of the unit. I would definitely recommend them!

I cannot recommend this plumber enough. Mladen Mladenov is highly professional, articulate, intelligent and probably the best plumber in Los Angeles. I received about 15 quotes for jobs to repipe and add a tankless water heater to my house. Mladen was the only one who suggested moving the heater to a different location, which made it less expensive and put it closer to the showers. He was also the only plumber to recommend CPVC piping, rather than copper. CPVC is less expensive and has a lower chance of leaking. I checked this out with my brother, who is a pipe-​fitter in another state.
When Mladen and his crew arrived, they were polite, clean and professional. They went straight to work and I could not be happier with the job they did. The walls were re-​patched when the work was done, the water heater works great and the new pipes are as quiet as can be. I would hire Mladen again in a second, and have recommended him to any of my friends looking for a plumber.

Terrible experience. DO NOT USE! Contact me and we will tell you the whole story if you’d like. Upshot is, we have the city coming out here to cite all the code violations and, as the company has been unresponsive to our complaints, we will be suing them for the job, our legal fees and considerable time wasted.
DO NOT USE!
UPDATE: We won in our complaint and received full payment back for the job from this company’s insurer. This company may do good work elsewhere and may be suitable for you but beware in the event of any dispute!
