A. O. Smith Cyclone Mxi Commercial Water Heater – Supplied & Professionally Installed by 4Most Energy

The A. O. Smith Cyclone® Mxi Series represents one of the most advanced commercial condensing water heating solutions available today. Designed for restaurants, apartment buildings, healthcare facilities, schools, hotels, offices, and institutional buildings, the Cyclone Mxi combines high thermal efficiency with intelligent controls and proven commercial durability.

Its fully modulating premix burner continuously adjusts firing rates to precisely match building hot water demand. This reduces fuel consumption, minimizes cycling, and helps maintain consistent outlet water temperatures while achieving thermal efficiencies of 95% or greater.

Inside the tank, the submerged helical heat exchanger maximizes heat transfer while reducing scale formation. The Permaglas® Ultra Coat™ glass lining and powered anode protection system provide long-lasting corrosion resistance in demanding water conditions.

Every Cyclone Mxi includes a color touchscreen control with built-in diagnostics, Intelligent Demand Response (IDR), Wi-Fi connectivity through iCOMM™, and compatibility with Building Management Systems using BACnet® or Modbus® gateways.

Proper sizing remains critical for commercial water heating performance. Our experienced technicians evaluate fixture demand, recovery requirements, storage capacity, incoming water temperature, gas supply, venting configuration, and available installation space before recommending the correct model.

Professional installation includes proper gas piping verification, condensate drainage, Category IV venting installation, combustion setup, electrical connections, safety testing, and system commissioning to ensure reliable long-term operation.

We had a great experience with Rey and his team during our new Rinnai boiler installation. The technicians did an amazing job and worked efficiently. The technician Sam was knowledgeable, professional, and respectful throughout the installation. He took the time to answer all my questions and made sure everything was properly checked before finishing the job. They arrived on time and completed the boiler installation on schedule. We are very happy with the service and would definitely recommend them to anyone looking for reliable and professional HVAC service. Thanks.

I was very pleased with the competitive pricing I got specifically from 4most energy. I contacted many companies to get their best quote. Sometimes there are even daughter or sister companies that will give you better quotes than the parent companies. It's best to check around for the identical product with installation from many companies. I was also pleased with the installers. They did have to cut away some insulation to install the Rinnai RX199 on the outside wall the house. Not sure if they should have tried replacing that insulation afterwards, but won't complain about the job they did because I think I got the best price on the market after getting quotes from about a dozen companies.

We recently had a Navien Combi boiler installed by 4Most Energy and had a great experience from start to finish. Rey was our sales representative and Sam was our technician, and both were excellent to work with. They arrived on time, the installation was fast and efficient, and everyone was friendly and professional throughout the process. Sam did a great job with the installation, and everything is working perfectly. We’re also very happy with the Navien Combi boiler itself. Overall, we couldn’t be happier with the service, the installation, and the product. We would definitely recommend 4Most Energy.

I contacted 4Most Energy to replace my 14 year old AC unit. Their intake process was smooth. They provided a reasonable quote the same day. The installation of the new AC unit was scheduled and the service provided by Farzad and his associate was completed within a reasonable time. They did a great job on the installation, hauled away the old equipment, and left the job site (both indoors and outdoors) in good condition. I would not hesitate to recommend 4Most Energy for your heating and cooling needs.

Great job Rey, Sam and team! My tankless water heater was broken for two months and after getting the run around from Enercare and Reliance, I decided on purchasing a Navien from 4Most Energy and they did a great job explaining the process and installing it the next day. Thank you for the top notch service!
