Very pleased with Erik's work Jan 28, 2026

I was very pleased with Erik's work. He clearly explained what he was doing to install a new heat pump system and what I should do afterwards to keep the system working perfectly. He communicated well with his team, and they worked as a cohesive unit. They stayed until the job was done, which was well after 6 PM.

Extremely Professional Technicians Nov 22, 2025

Rock technicians Anthony, Fidel, and Nick replaced our electrical panel, furnace, and AC with heat pump. They were all extremely professional—on time, careful, courteous, and answered all questions. Highly recommended!

Did an Absolutely Fantastic Job Nov 4, 2025

My older furnace died during a cold snap in late October 2025, and Rock was the only place that was able to come out to help the same day. After some diagnostics, I came to the decision that it would be best to have a new system installed. Rock was able to come out the next day to install a heat pump-based system and did an absolutely fantastic job. Everyone from sales to the technicians was extremely friendly, helpful, and considerate. The new system just passed all inspections and has been running like a top. I would recommend Rock to anyone. Thank you so much!!

Their quality and service is unsurpassed Aug 26, 2025

Rock did a fabulous job replacing my furnace and coils and installing a brand new heat pump to replace the outside condenser. They first evaluated the builder-installed systems (no charge given my club membership), and showed me exactly what was wrong with the 16-year-old equipment. The same day I had their quotes to replace everything with either a conventional system (no heat pump) or one with a new heat pump. They were out in force here to do the work only two days later. I’m overjoyed with the new system. The heat pump is virtually silent compared to a traditional outside condenser. They quality controlled the new installation and showed me everything an owner needs to know. They were most responsive to my questions. They were very careful in being sure that the new heat pump is solidly anchored to the surface outside. They are handling all warranty registrations and other paperwork for rebates and tax credits related to the heat pump. They are not the least expensive around but my belief is that their quality and service is unsurpassed. This is a first-rate business.

I could not have had a better experience Jun 15, 2024

Rob came out the same day to give me an estimate for a heat pump vs AC. He was incredibly knowledgeable and explained things thoroughly. I could not have had a better experience with this process.

Great experience with Josh Feb 19, 2024

My husband and I had a great experience with Josh the last several days in getting our air handler electric heater fixed and running appropriately. We were under the impression we'd had an air handler and heat pump installed when an AC unit had been installed (by a separate company approximately 2 years ago). The air handler itself has been installed incorrectly, below code, and dangerously. We originally called Rock PHAC in early January. After a mix-up in part ordering that delayed (by several weeks) the needed repair due to the incorrect install, Tiffany was able to get us a new technician to come out and reassess our situation. Josh was extremely knowledgeable about our situation and fixed the immediate concern with the air handler. We also elected to have a heat pump installed through Josh and Rock PHAC. They were able to fit us in within days. Josh returned with Dakota and both were efficient, professional, personable, and knowledgeable. I will specifically be referring friends who want to install air handlers and heat pumps to Josh, and will continue our maintenance for our units with Rock PHAC. They were good to work with in regards to the part mix-up and getting our incorrectly installed units appropriately reinstalled and running.

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. Rock Heating and Plumbing was easy to work with to schedule our appointments and kept us up to date regarding the time their technicians would arrive at our home.

Justin Found the Culprit Fast Apr 17, 2026

Carlos Made It Incredibly Easy Apr 13, 2026

Honestly, I was so stressed about my plumbing, but Carlos made it incredibly easy. He fixed everything quickly, was kind and professional, and the price was very fair. 10/10, would absolutely recommend!

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

Highly recommended Mar 20, 2026

I decided to replace both of my ductless water heaters in the morning, and Jacob and Mitch finished the job perfectly by the end of the day. They are quick and professional at what they are doing. Highly recommended.

Very Happy With My New Water Heater Mar 18, 2026

I needed a new water heater ASAP, and Carlos came and installed it within 2 days. It was nice to be able to get a quote on a weekend! The whole process took only a few hours and I’m very happy with my new water heater.

Ashley Van Woensel

I would highly recommend Rock Mar 18, 2026

We live in Lakewood and hired Rock for a plumbing leak in our bathroom. Ashley was able to get us scheduled immediately. Justin was sent to do the job and was fabulous. He had great customer service skills and got the job done in a timely manner. I would highly recommend Rock.

Benjamin Timmer

Did an outstanding job for us, twice Mar 17, 2026

After performing stellar work in our home, replacing old galvanized water distribution pipe and several faucets and a shower assembly, Cesar returned to address our high household water pressure (>100 PSI) to protect our indoor plumbing. This required clearing our outside shutoff, digging out the meter yoke assembly hole for access, and installing a PRV (pressure-reducing valve) inside by the main indoor shutoff. Cesar's knowledge of both inside and outside (top and bottom) plumbing systems was evident. He was efficient, courteous, cleaned up and restored the area of the digging, and did an outstanding job for us, twice. Highly recommend!

Genghis Acustik

Top-notch, professional, and honest Mar 13, 2026

I deal with a lot of vendors. These guys are top notch, professional, knowledgeable, honest, and a breath of fresh air! We set them up with all our locations as a result of Jacob's amazing demeanor, knowledge, and dedication to the craft. It makes managing maintenance from offsite a lot less stressful!

Brian Schlenk

Professional, Efficient, and Knowledgeable Mar 11, 2026

Carlos was professional, efficient, and knowledgeable. In addition to doing a great job, he saved me about $1,800 from a solution from a different plumbing company. He also was great at answering my questions and letting my chocolate lab greet him continually. Lol.

Ricky and Nick were spectacular! Mar 6, 2026
