Professional Commercial Water Heater Repair & Installation in Cerritos
Reliable hot water is essential for restaurants, hotels, healthcare facilities, and many commercial operations. Our commercial water heater services ensure consistent hot water supply for your business needs. We service all types of commercial water heaters including tank storage water heaters, tankless water heaters (on-demand), commercial-grade point-of-use heaters, and high-efficiency condensing units. Our experience includes Bosch and other leading commercial water heater brands. Commercial water heaters work much harder than residential units, requiring professional installation, regular maintenance, and expert repairs. High-demand applications stress components and require experienced technicians for reliable service. Common water heater problems include no hot water, insufficient hot water, temperature fluctuations, leaks, unusual noises, pilot light issues, and sediment buildup. We diagnose and repair gas valves, heating elements, thermostats, pressure relief valves, and all other components. Tankless water heaters provide endless hot water and take less space but require different service expertise. We service all aspects of tankless systems including descaling, flow sensor cleaning, burner maintenance, and heat exchanger service. Our water heater installation service includes proper sizing for your hot water demands, equipment selection (tank vs tankless), professional installation with gas and water line connections, expansion tank installation, proper venting, temperature and pressure relief valve, and complete system testing. Preventive maintenance for commercial water heaters includes flushing sediment, testing temperature and pressure relief valve, checking anode rod (tank heaters), inspecting burner operation, testing thermostat operation, and checking all connections for leaks. Regular maintenance extends water heater life, improves energy efficiency, prevents catastrophic failures, and ensures consistent hot water for your operations. Commercial water heaters can last 10-15 years with proper professional care.

I highly recommend this AC repair company! They did an excellent job fixing my air conditioner — fast, professional, and very reliable. I also had my commercial freezer repaired by them, and just like before, the service was top-notch. Their team really knows what they're doing, and they always make sure everything is working perfectly before they leave. Definitely the best repair service I've worked with!

We had an issue with our walk-in freezer and these guys were amazing. They showed up quickly, diagnosed the problem right away, and had everything up and running in no time. Professional, knowledgeable, and very easy to work with. Highly recommended for any commercial refrigeration needs!

Called them to service a commercial ice machine. They were able to send out a technician the next day. He was able to diagnose the issue and fixed the machine. He also stayed for a few cycles, to make sure the issue was resolved.

We found this company on Google. Iriana is excellent customer service. Alex is genius. He repaired 2 of our refrigerators that had major issues. He found the issue and he fixed it immediately. Request for Alex for sure.

Have a small commercial fridge that was running constantly so needed a check up. seemed the thermostat was broken. got a new one as well as a cleaning of the condensor. working well now hope the electric bill will go down. After a few months I noticed the fixed fridge didn't seem to be working optimally still and had them send a tech out to check. turns out it's a 13 y o fridge with all original parts. a good sign but also a sign that on the original inspection that tech probably should have checked the coolant levels. long story short, turns out after checking the levels were low and more was added. it now is really working as it should. The best part of this review is that after paying, I thought about it more and called them asking for some sort of reduction on the bill as it all could have been addressed in the first visit. I thought only paying for 1/2 of the service fee visit (not the coolant of course) would be a fair compromise. after thinking it over on their end they actually reimbursed me for the entire service fee. I am impressed at their level of service, customer service and business sense.
