Traditional & Tankless Hot Water Heater Solutions

Before the chill of a cold Orange County winter is here, you want to ensure your tankless water heater is at 100% efficiency and can supply the hot water you need. That’s why it is important to have your tankless water heater serviced with annual maintenance. A tankless hot water heater maintenance tune-up has 3 primary benefits:

Increased Water Heater Efficiency & Money Saved: One of the most common issues to occur in your tankless water heater is buildup of sediment from loose minerals in your Orange County water supply. The more buildup, the less efficient your water heating unit becomes. Banging or knocking is usually an indication of buildup in the heat exchanger of your tankless water heater, and that means it’s time to call the experts at CastleWorks Water Heaters of Orange County to get your annual tankless water heater maintenance.
Minimize the Risk of Tankless Water Heater Breakdown: By having your tankless water heater maintained annually in Orange County, you decrease the risk of a costly tankless water heater repair or tankless water heater installation. Our experts will tune-up your tankless water heater and check for any signs of corrosion, water leakage, or anything else that may be keeping your tankless water heater from functioning at 100% efficiency.
Ensure Hot Water All Year Long: There’s nothing worse than waking up to cold water running through your shower. Ensure this doesn’t happen to your Orange County tankless water heater by getting your annual maintenance tune-up scheduled today with the expert plumbers at CastleWorks Water Heaters of Orange County.

As you pick up the phone, the first question running through your mind is probably whether you need to repair or replace. Immediately on arrival, our experts will assess your unit and provide a quick and accurate diagnosis of the problem so you are well-informed about why your heater is acting up and what can be done about it. If it’s a simple repair, our techs should be able to get your water heater up and running again in a single visit.

 Trustindex verifies that the original source of the review is Google. We needed to replace our large 100 gal water heater (4.5 Ba house) and called Castleeworks when some slight leakage was visible in the drain pan.  Great same-day service by Salvador Vidales, who provided the price estimate, consulted with us on options, and got us an additional discount because we were replacing with the exact same brand that they usually install, so no new major piping was rquired other than the usual new connectors. Waived the delivery fee for the new unit which was in Pomona several hours away on high traffic congestion day.. Salvador was also the installer, very capable and workmanlike.  Had the whole worksite set up and old unit ready for removal when the delivery/installation guys arrived on the hottest day of the year. When the new alumuinum drain pan got dented in the installation on our raised pad which didn't look good, he pro-actively had the team pull the new unit back off and installed another replacement drain pan to make sure we were happy with the results.  After the delivery guys left when the unit was in place, he worked for several more hours finishing at 7 pm.  Showed good workmanship, gave us good advice.  We were very happy with Salvador and the company so far at this point.  Obviously the proof of the pudding will be in the new unit and our service contracts and warranties, but we're off to a very good start and would highly recommend based on this experience on Day One!

 Trustindex verifies that the original source of the review is Google. I am more than satisfied with the service I received from Castleworks Home Services.  From taking my phone call after hours when I discovered that my water heater was broken and leaking, and scheduling an appointment for the very next day… to keeping me updated on the estimated arrival time of my technician including a text with his full name and photo ID was truly impressive.  But what was even more impressive is the actual service itself.  Justin, the technician, was extremely easy to work with.  He was knowledgeable, polite, explained everything, answered all of my questions, and completed all of the work in one visit.  I couldn’t ask for a better experience and highly recommend this company! 5 ⭐️⭐️⭐️⭐️⭐️

 Trustindex verifies that the original source of the review is Google. We have just had 2 excellent experiences with Castleworks. Picked up the phone right away and was great with communication via phone and text to keep us informed as to when our technician would be out. And Justin the technician himself was absolutely amazing. Knowledgeable, worked clean and quick. We had such a good experience we ended up calling them back out right away for another issue with A/C that was long overdue and had another great experience with Brendan. So hard to find reputable companies that do what they say and that you can trust. Fully recommend them. Save their number!

 Trustindex verifies that the original source of the review is Google. James Skresvig went above and beyond for me. He even changed a hose for me, completely unrelated to the job he came to do, just to help me out because I didn't have the right tool. He answered all of my questions and was very good at explaining their services without overselling anything - more like explaining options.
