Even though we design and build mechanical HVAC systems engineered to last, our quality service only goes so far. That’s why we prefer the leading brands and manufacturers of commercial mechanical systems,” shares a spokesperson of Hoffmann Brothers Mechanical Contractors.

For 20 plus years Robert Hoffmann has been living up to his company’s commitment in designing high efficient mechanical systems for commercial properties in St. Charles County.

“We’re all about performance driven mechanical design. If an HVAC-R system does not support energy conservation, we won’t design it or build it,” attests a technician of the 20-plus year old mechanical HVAC firm in St. Charles County.

Here is a mini preview of the mechanical companies’ preferred brands in boilers, water heaters and variable refrigerant volumes (VRV).


Many of the companies we provide service, rely on their building’s water heating system to produce goods and services, where hot water is mission critical (in example, wineries, breweries, spa services, hotels and other commercial spaces).

Customer reviews and ratings suggest that Lochnivar’s commercial water heating products are quite agile. Because these water heating systems are available in numerous sizes, numerous water pressures, and at various water hardness, many mechanical contractors, who are members of the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) consider the Lochnivar water heating system to be compatible with most other mechanical systems and brands.

Robert Hoffmann, a licensed mechanical engineer and founder of Hoffmann Brothers Mechanical Contractors points out a few benefits of a VRF ductless heating and air conditioning system.

Ductless Air Conditioning

Variable refrigerant flow (VRF), also referred to as a variable refrigerant volume (VRV)

is an emerging technology for commercial spaces in St. Charles County. This heating and cooling system operates without the need of any air ducts. A single outdoor condensing unit feeds warmth or cool air to each indoor fan coil. These flexible mechanical systems accommodate apartment buildings, hotels, offices and other commercial spaces where users can manage their own energy efficiency.

Roof Top Unit (RTU)

In the way of roof top unit (RTU) or rooftop units, Hoffmann Brothers prefers mechanical systems designed by Trane. This brand of mechanical HVAC systems afford fast installation time and retrofit with most existing HVAC-Rs.

The aforementioned list of HVAC-R manufacturers is a very, very shortlist of leading brands in mechanical HVAC systems. Please call us at 314.664.3536 to learn more.
