Extremely courteous, knowledgeable, and professional Feb 19, 2026

Jacob L. installed water arrestors to solve a water hammering problem and cleaned up some drain issues. This was the second time that Jacob has done work for us, and both times he was extremely courteous, knowledgeable, and professional, as well as being very efficient. Jacob thoroughly explained each estimate and went through the work to be done before starting and reviewed the completed job to make sure that we were satisfied with the work before he left.

This company is great! Aug 12, 2025

I have used Rock Heating and Air Conditioning for years. They are honest and fairly priced. Mario, the plumbing specialist, did a great job today. He fixed a drain issue in my bathroom that I have literally had issues with for 30 years. This company is great!

Solved our issue quickly and efficiently Aug 11, 2025

We had an issue with a clogged kitchen drain line somewhere past the Y and deeper than my clean-out snake could reach. Santiago arrived with a much more efficient power snake and solved our issue quickly and efficiently. Much appreciated his professionalism and quality of work. They also accepted cash, which is extra convenient! Myself and my company, we’re a licensed general contracting company here in the City of Denver (HYS Construction Development LLC), and a quality go-to service company is always something that we use for service, mainly on TI projects. Will definitely call again.

Santiago M Is the GOAT! Jun 28, 2025

Santiago M is the GOAT! We had a few other plumbers come by who couldn’t solve the problem, but Santiago did it and made it look easy. The problem (blockage) was worse than we thought and he got down and dirty and cut out a big chunk of the piping to show us how bad it was, and it was bad. But he cleared it and all systems are flowing smoothly! Amazing!

Professional and Courteous Service Mar 25, 2025

Jacob came and cleaned out our bathroom drain that was draining way too slow. He was professional, courteous, and able to provide service the same day the problem was diagnosed. Thank you so much, Jacob.

Finished Work Is Excellent Mar 12, 2025

Two plumbers from Rock replaced our exterior drainage from the sump pump and gutters in under one day's time. The finished work is excellent in appearance, and drainage works fine now.

Santiago's wise counsel saved me Mar 7, 2025

Why is it every time my husband leaves town, something in our house breaks? This time it was a kitchen sink that was draining far too slowly. After doing everything I knew to fix it, including checking the P-trap to see if it was clogged, I finally called Rock Plumbing. They sent Santiago M. out the same day I called. He put a probe down the sink to see where the problem was, but it kept getting stuck. On his monitor, I could watch what he was doing and saw what the probe "saw." I already could see what the potential problem was. Our drainage pipe was blocked by an excessive amount of "gunk"/old food debris. We then went to the basement and he had me push against the drainage pipe where he suspected the clog was to feel how heavy it was, and then had me compare it to the weight of a normal-feeling pipe. He gave me 3 estimates to potentially remedy the problem (from least expensive to most expensive) - snaking, using a high-pressure jet, replacing the clogged section of pipe. He explained in detail the potential difficulties of snaking or using a high-pressure jet and cautioned me to be aware of the added costs of failed attempts to fix the problem. There was no pressure from Santiago to choose the option of replacing the section of clogged pipe, the most expensive option. He even scheduled the repair the following day to give me enough time to check with my husband. I am so thankful for Santiago! He understood my predicament of having to make a tough choice on my own and gave me all the factual and financial information I needed to explain the situation and reason for choosing the most expensive to my husband. The job is finished. My kitchen sink drains beautifully. Santiago completed the job in 1.5 hrs - pretty impressive for doing it solo! He showed me the section of pipe he removed and it turned out, there was no way the two lesser priced options would have worked. Santiago's wise counsel saved me almost $900.00! Never having had to deal with major plumbing issues before, I expected this job might be difficult to understand all the details involved in repairing the problem, and really expensive. Because of his patience in explaining and showing me every step of the process and giving me his expertise with respect to the financial implications of the options, Santiago proved he was a great advocate for the clients he serves. Rock Plumbing and Santiago have set the bar high and I'm grateful to have been the recipient of the excellent service they gave my husband and me. Santiago M. is an outstanding technician and Rock Plumbing, Heating & Air Conditioning is fortunate to have him!

Quickly Removed the Clog Oct 23, 2024

Jacob arrived on time and answered all of my questions, he quickly diagnosed our drain problem, and quickly removed the clog. We were able to test the drain, which no longer backed up. The whole time he answered all my questions and even gave me advice about the other drains in the house. 5 stars.

Michael Shepherd

Overall, a Great Experience Aug 21, 2024

Mario came to my house to help me cap off a drain in the basement. He was very friendly and professional. When he came into the house, he covered his shoes and immediately got to work investigating the worksite. He asked knowledgeable questions about the project and why we wanted to cap the drain. Instead of doing over $1500 of work, he offered other solutions that were simpler. He even offered recommendations on how to level the floor. I was only charged the initial fee to come out, but the information he provided was worth way more. Overall, a great experience.

Jacob Lopez was a great technician Jul 26, 2024

Rock Plumbing here today to address a clog that was resulting in us not being able to do a number of things. They came within a small number of hours of our call. Jacob Lopez was a great technician - clear communication, accurate expectations, quality work.

So grateful for the service with Rock Jul 17, 2024

Jacob Lopez helped me today with a drain clog. He explained what he thought the problem was and went through options with me before going ahead. He also showed me how I can prevent issues in the future, which I really appreciated! I am so grateful for the service with Rock, always so easy to book an appointment and easy the day of. Thank you, Jacob!

He Got Right to Work Jul 8, 2024

Jake was my technician that showed up. He got right to work and performed my requested basement floor drain test and ensured it was draining and working properly. Will be setting up follow-on appointments with Rock and Jake to get everything working optimally. Thanks again Rock and Jake!

Thank You for the Quick Response Aug 3, 2023

Mark did a great job getting the water to go down the drain again. He came quickly after I called in the problem, and it was nice to have a technician I had seen before. Thank you for the quick response and great service.

Mark Was Fantastic Aug 2, 2023

Mark was fantastic! Not only did he fix my drain problem, he was able to identify and fix a problem I have been trying to resolve for years! I am so happy with the professional, courteous, and thorough service I received.

No High Pressure Tactics Apr 3, 2023

Mark, a technician with Rock Plumbing and Heating, was pleasant, professional, thorough. He had a trainee with him, but that certainly didn't diminish the quality of the work or his attention to updating the homeowner - me. I had an improper drain plumbing job done by a previous plumber which Mark identified but gave me the option to replace because it was functional - just smelly and not correct. No high pressure tactics. Highly recommend!

Tyler did a great job! Feb 11, 2022

Ricky Was Just the Best Apr 12, 2026

We had Rock Plumbing, HVAC, and Electrical put up a ceiling fan, 2 ceiling lights, and 3 island pendants. Ricky was our electrician and he was fantastic. He was very friendly, knowledgeable, and quick. He was just the best. We would use Rock over and over again. Ricky is definitely an asset to the company, thanks again.

Very pleased with the crew Mar 30, 2026

We were very pleased with the competence and professionalism of the crew that worked tirelessly on installing various electrical components in our basement. They were courteous and respectful in all their interactions with us and went beyond what was called for with our project. Their cleanup was thorough. The four individuals that worked on our project were: Ricky, Fidel, Antonio, and Hailie. We wouldn't hesitate to have them do work for us again.

Extremely friendly, kind, and professional Mar 14, 2026

Great service! Rock has installed our water heater previously and did a fabulous job. I enrolled in their "maintenance club" and had both electrical and HVAC inspections done. I was so impressed with the technicians that came out to do the inspections and maintenance. They thoroughly investigated our electrical system and completely inspected and serviced our furnace. Where they encountered small things that weren't right, they fixed them on the spot. Extremely friendly, kind, courteous, knowledgeable, and professional. I definitely recommend Rock!

Highly Recommend Austin and Jacob Apr 20, 2026

Austin and Jacob were amazing, and I would highly recommend them for plumbing and boiler repairs. They were friendly, professional, and highly knowledgeable about the technical issues we were dealing with regarding our gas fireplace and boiler.

He quickly had everything on the truck Mar 31, 2026

I had an outdoor faucet extending from my home that was leaking when in use. Jacob from Rock Heating & Plumbing diagnosed it, realizing that model type of faucet was not available anymore. He quickly had everything on the truck to install a newer model. He repaired the copper water line as well, and now good to go! Steven
