I met Erik through my motorcycle shop over two decades ago. Not only do I look up to and admire him for his business ethics and professionalism, Eric has become one of my best friends. In fact, Eric hired me to work for him for several years. He and I installed over 400 tankless water heaters together. One of which was my unit, now 12 years old. We recently had a conversation, and he asked if I still had the same unit. The answer was, yes! He was surprised, as followed by recommendations, I have kept it cleaned every year with the vinegar treatment. Probably going to upgrade to the more efficient version soon! Arnetts Water Systems will be the only one I will refer to and use.

I really appreciate the level of service that Erik Arnett and his team provided. I have had my Rinnai tankless water heater for about a month now and it has worked perfectly, replacing a 75 gallon tank heater in the garage. The heater they spec'd is able to keep up with 4 simultaneous showers with capacity left for running a few faucets. Erik's team was extremely prompt in scheduling the appointment, provided an excellent recommendation regarding placement of the heater, and did a very 'clean' install. There were no hassles from the moment they showed up in the morning until they swept up the last bit of dust in the afternoon. I would definitely hire them again.

I give this company 5 stars for service. The install was professional, and the company arrived when they said they would and finished when they said they would. They did a top notch job. I highly recommend this company. I had three quotes, and by far this company was the most professional.

Great service. The staff is super helpful and they ARE FAST! The first place you should call.
This guy is good! Fast service and great at helping me understand what was really needed. Saved me a ton of cash and held my hand the whole way.

I called various places for replacing my 50 gallon water tank heater with a tankless water heater and they all gave me a very large range for the cost, and also could not come to my house at the same day. Then I called Arnett's Water System and talked to Eric and he provided me with a cost over the phone which was much less than the quotes that I received from the other places. Eric came over to my house the same day and his phone cost estimate did not change after seeing my system. In 2 and a half hours, Eric replaced my 50 gallon tank water heater with the more efficient tankless water heater. I watched Eric do the work, he was very efficient and fast, I could tell that he has lots of experience in doing that. I am very pleased with my new tankless water heater performance, and its small size as compared to the bulky tank that I replaced. I highly recommend Arnett's Water Systems for your water heater needs, the price was the best, and Eric is the most professional, honest, and knowledgeable person that you could find for this kind of work.

Our 11 year old Noritz stopped working. Eric had an even better version installed before we could miss the hot water. Bravo!
Roger H.

Had an overall impressive impression of Arnettt's plumbing. The guys were great Tom and Carlos. Did great work and were definitely a big help to my problem.

We hired Arnett's to install our tankless water heater. They did a great job, it was quick and good price. No problems, nice guy.

Great guys, Eric knows everything about tankless and their prices are very fair. I tell all my friends and family to call him for their water heater needs.
