1) Old water heater 2) New water heater

Own a 2 yr old water heater with a 6 yr warranty. The gas valve in the central control unit stopped operating. Had to replace ALL of the unit, wiring and hose for over $600. Felt over charged. I asked Chris, a VERY polite, knowledgeable and capable fellow to go ahead and perform an annual tank drainage while he was present. The bill went over $800. The company folks were all polite & easily understood. They were wonderfully timely on short notice ( I called around 9:15, Chris came around 11:15, on my rare Monday off.) The balance of my immediate need vs the financial impact of the service is hard to judge.

Daniel was Awesome! Clean, communicated with us About what was gonna happen. Even answer questions about other products they have available.
We definitely recommend Daniel and the company he works with

Luis is great, and has been part of the Moore Mechanical Team for years. Now CastleWorks is the parent company, but many of the same team including Luis. They are very good.

Luis replaced my water tank heater and did an excellent job. Prompt, professional, and tidy work. Highly recommend!

Scott. R from CastleWorks showed up within an hour after calling and did an amazing job replacing our hot water heater. After the install he went over every detail of the new heater and made sure I knew what to do in case of an emergency. He was extremely polite and professional and I can tell he takes pride in his work. I would recommend these guys to anyone.

We had a pin hole in our water heater pipe, shooting water to the wall as well as making a mess on the floor of the garage. Luis Valencia and Jovan Fortune from this company came over and fixed the issue very quickly. Both of them answered every question we had and did a very neat job. I will highly recommend them.

Excellent service from start to finish. The technician explained everything clearly, and installed the water heater quickly and professionally. Very satisfied with the quality of work. Thank you Miguel !

Luis was awesome! He was prompt & professional! He explained clearly what the issue was with the water heater & provided several options. I opted to have the water heater replaced & it was done that same day! Thank you Luis & Castleworks!

Great service from Amanda and Nam. We had hot water back after less than 24 hours. Nam (technician)analyzed and explained our issue, and replaced the controller as needed. Very reliable and efficient folks.

Professional guy ,do the job really quick after all done, clean all the trash. Great job !

Luis Valencia is awesome. He is very informative and professional. He was patient with us and helped us find the best deal for us. I called Castleworks first thing in the morning and they were done before noon.

Otis did an excellent job & fully explained in detail on how the system works plus how it operates. I will definitely recommend CastleWorks Water Heaters . Good job done by Otis . More power to your company

I had a leaking water heater and called Castleworks to get a technician to take a look ! Luis Valencia came d to to do the repair ! He was the best person I have ever dealt with emergency repairs ! He educated me on what happened and the cost of the repair ! My new water heater was installed within 2hours and he was a pleasure to work with !

James was prompt, efficient and has great communication skills. We were very happy with his work!

Nam Park came to my home to replace my water heater and I couldn't be more satisfied with the service provided! He was super friendly and knew exactly what he was doing. Got everything up and running in no time. I highly recommend Nam to anyone in need of water heater repairs/replacements. Thank you Nam for your excellent service!

Our water heater started leaking yesterday at 4 PM and CastleWorks was able to send a technician, Elston, out by Noon the next day. Elston went through all of our options and pricepoints and even financing. Once we decided which unit to go with Elston acted quickly and was able to replace with a brand new gas water heater within a few hours. Very professional and a perfect gentleman!

On time.
Nam explained all of my options, costs, and benefits. Friendly and cleaned up after he finished. If I have any future water heater needs, I'll definitely give them a call.

Noritz error code 90 due to airflow issue. Serviced by Elston, who was fantastic. He did a thorough service, removing the manifold and fan, cleaning it of all dust and debris that inhibited the airflow, and the problem did not repeat last night. It usually occurred twice a night. So we think it’s resolved permanently.
