I luckily found Conejo Plumbing on Yelp to service our tankless hot water heater, after my original plumber reneged on my lifetime contract. The plumber “Dier” was early for our appointment and after pleasantries was eager to solve the intermittent ignition issues we were experiencing. After an inspection it was noted that the igniter and flame rods had carbon and rust built up. Instead of soaking a customer and replacing our unit a simple service call got us back up and running. I can’t thank Conejo and “Dier” for the prompt service call and their professionalism. Suffice it to say Conejo will be my first call for plumbing issues and I look forward to seeing them in the future for HVAC calls as well. If you’re in need of a professional plumber I highly recommend Conejo as your first choice.

Had my water heater replaced (on a mobile home). Crew was courteous, fast and clean. They brought the system up to code and left my place cleaner than when they arrived. All the techs I've talked to have been professional, to the point and treated me with respect and a sense of humor. All much appreciated. THank you.

I wouldn't hesitate to call this company again. Our technician Craig McConnell was very helpful and extremely knowledgeable. He fixed our leaking water heater very quickly and effectively and answered every question I had offering plenty of advice and information about our hvac system. They will be the first ones I call if something goes wrong in the future.

Damian came to the house to review our water heater. Gas Co said it wasn't safe due to it not ventilating properly. Damian was extremely friendly, knew sound troubleshooting techniques, and used escalations to his experts to find that we had a bad vent cap on the roof. He went ON the roof to remove and measure the vent cap so we could get a new one. Now we can say goodbye to backdraft and the thread of carbon monoxide in our garage! What a great value - vs having to buy a whole new water heater.

Our water heater in our rental went bad. Conejo had a real person pick up when we called, scheduled an appointment and their tech arrived on time. Our has has a skinny/non-traditional unit that couldn't come until Monday but they installed a temp unit so we had hot water Sunday night - a real blessing. Great service - you get what you pay for!

Showed up on time, did AC and water heater work quickly. Identified need and installed with my OK, two surge protectors and an overflow tank alarm / cut off switch. The tech, Fernando, is knowledgeable and helpful. Highly recommend to all.

They were great! They communicated the timing and costs, and were able to answer all of our questions. They assessed the problem and were able to replace our water heater all within the same day! Very friendly and professional.

Our old water heat leaked and I called Conejo in the morning. They came the same day and installed the new heater within a very short time. Tyler and Yasser did a great job!

Great service - on a weekend too. It's been over one year that I have used the new hot water heater. No problems. I always have hot water whenever I need it. No running out during any usage. Thank you for giving me back hot water on a consistent basis!

Great experience! Four techs came out to replace my hot water heater and install attic insulation. They were knowledgeable, efficient, and very professional. Everything works great and they left the area spotless. Highly recommend!

The service technicians are so kind and knowledgeable, and the customer service is amazing. I've had home service providers before who were terrible so it really makes all the difference when they enjoy and do an amazing job. Clearly the company is ran well, the prices are right, and I highly recommend them for anyone in the Conejo Valley needing service on their heating or air conditioning or water heater. Thank you John and Justin for your great service to my home!

I want to give a big thank you to Jeff Stone for helping me with my water heater. I smelled gas and was very concerned. Jeff came by, checked everything out, quickly found the issue, and took care of it. He was polite, kind, and very helpful. I really appreciate that he acknowledged I was a woman worried and in need of assistance which made me feel heard and safe during a stressful situation. Appreciate your patience and professionalism. Thank you, Jeff!
