Mechanical Contractor Talks Safety Preparedness

With September being the month for emergency preparedness in America, does your commercial building in St. Charles County have a contingency plan? What is your commercial building's crisis management plan?

Earthquakes, floods, bioterrorism, chemical spills and other natural disasters represent a short list of emergency situations, facing St. Charles County commercial property owners.

Flooding and tornadoes represent the most common potential natural disasters of St. Charles County. Missouri is among 37 other states vulnerable to earthquakes. The New Madrid seismic zone produced quadruple earthquakes magnitudes, ranging above 7.0 on the Richter scale, during the winter of 1811 to 1812.

Hoffmann Brothers Mechanical Contractors prescribes five rudimentary tactics in observance of emergency awareness month in America.

1) Schedule an inspection on your building's mechanical system to identify any combustive or air quality problems. Your commercial building mechanics play a vital role in emergency prevention. Well maintained boilers, furnaces, roof top units and other HVAC-Rs complement workplace safety, preventing unforeseen scenarios.

2) Compile all emergency supplies for the occupants of the building (for example: hazmat, emergency kit). Please visit for a complete emergency kit list.

3) Organize an emergency task force to help plan and institute drills and other urgent contingencies. Create a schedule for practice drills.

4) Designate a location to use as a shelter in the event of an emergency situation. Basements and spaces away from windows serve as ideal locations to quarantine occupants in the event of an emergency.

5) Install a building automation system (BAS) to monitor and defend your commercial property's safety.

6) Remain apprised of local emergency events and evacuation to plan accordingly.

In Jefferson County, St. Louis County and St. Charles County, many small-business owners are unaware of a utility rebate program provided by Missouri Gas Energy (MGE). Eligible organizations earn a rebate with the investment and installation of a qualifying gas water heating and space-heating appliance.

A media representative of Hoffmann Brothers Mechanical Contractors answers common questions pertaining to the rebate incentive, available Jefferson County, St. Louis County and St. Charles County.

Are small businesses the only types of businesses, eligible for a rebate?

Yes. Construction companies, and building developers, who install natural gas qualifying systems are eligible for the MGE rebate.

What types of mechanical HVAC-R systems qualify for the rebate?

In order to quality for the small business rebate, the commercial property must use natural gas. Eligible goods have to be EnergyStar rated. Tanked and tankless water heaters, forced-air furnace, boilers and programmable thermostats qualify for the utility rebate program.

For additional details, pertaining to the MGE rebate program, please visit

What are the energy equipment prerequisites to quality for the utility rebate?

The Energy Star program was designed by the U.S. Department of Energy and the Environmental Protection Agency. As a result, these appliances have to meet or exceed certain energy specifications: energy factor (EF) and annual fuel utilization efficiency (AFUE). Here's a breakdown of mechanicals systems covered by the MGE program:

Water heaters

Both tanked and tankless water heaters are included in the utility rebate program. The minimum standard for a tank water heater is .62 AFUE. However, an on demand or tankless water heater calls for and EF of .82 r heater.


Note that the MGE rebate program covers an air-forced furnace with at least a .82 energy factor.

Is there a cap or limit on the amount of the energy rebate?

Yes, each mechanical HVAC and/or water-heating appliance - Tankless water heaters are covered up to $200. However, the energy rebate for a tanked water heater ranges from $50 to $200, depending on the model and its energy efficiency. For an ENERGY STAR certified boiler or furnace, rebates start at $200.


Are there any other noteworthy eligibility requirements for MGE rebate program?

Yes, only mechanical engineers, certified with the ENERGY STAR program have the authorization to institute any for the aforementioned upgrade installations.

In Jefferson County, facility maintenance and housekeeping are not the sole approaches in alleviating a toxic odor in the workplace. Quite often, these indoor air quality (IAQ) issues entail several steps to diffuse an unsavory smell.

Because the Occupational Safety and Health Administration (OSHA) and the U.S. Environmental Protection Agency (EPA) mandate specific indoor air quality specifications and energy minimum standards. “Killing a toxic odor necessitates a few state and federal compliance standards,” recommends Robert Hoffmann, licensed mechanical engineer and founder of Hoffmann Brothers Mechanical contractors.

1) Identify the cause to manage source control.

2) Make a note of copy machines, servers and other office equipment that maybe promoting airborne contaminants and odor.

3) Relocate any equipment that used electricity or fossil fuels to a space with good ventilation.

4) Where possible, seal off any rooms, and applications emitting toxic smells or volatile organic compounds (VOCs).

5) Institute guidelines for your building. Ask leasers to relocate any office equipment that emits heat to a ventilated area. Restrict or ban cigarette smoking to areas away for exterior building vents.

6) Obtain bids from mechanical engineers and contractor, licensed in Jefferson County to clean and purify your buildings air. Once the air cleaning is complete, a mechanical contractor should be able to plan and prevent further IAQ contamination.

In certain cases, another mechanical system is necessary to augment ventilation and healthy IAQ. From a variable refrigerant volume (VRV) to an air purification system, a mechanical contractor will have to design a solution with the following qualities:

ü  Does not re-circulate air comprised of contaminants.

ü  Alleviates toxic odors, promoting good IAQ.

ü  Complies with energy conservation standards of local, state and federal guidelines.

Let us kill any toxic odors, ailing your commercial building. We design build HVAC-R systems--built to last in compliance with all regulations.

As July 3 through August 15, marks, “Air Conditioning Appreciation Days,” many commercial property managers in North County Missouri maybe investigating approaches to ensure energy conservation. With air-conditioning the accounting for almost 40% of a commercial building’s energy consumption in the summer, energy conservation remains a top priority in North County, Missouri.

Robert Hoffmann, the founder and principal owner of Hoffmann Brothers Mechanical Systems provides a shortlist of strategies to drive down energy consumption.

Start with an energy audit. The assessment involves a comprehensive inspection of commercial building’s heating, cooling, ventilation and refrigeration systems to gauge energy losses. A mechanical engineer may be able to recommend simple fixes to improve a building's energy conservation by at least 15%.

To boost energy conservation in North County, monthly maintenance is integral for reducing greenhouse gases, and monthly energy expenditures. Monthly maintenance also influences a mechanical system’s performance and indoor air quality (IAQ). Not to mention, particulate matter and other airborne contaminants are predisposed to commercial environments, where there is a lot of activity.

Note that HEPA filters complement both indoor air quality and a commercial building’s energy efficiency.

Replace outmoded mechanical systems with high-energy efficient HVAC-Rs. Older furnaces, boilers, heat pumps, and other mechanical systems attribute to significant energy loss. As the U.S. Environmental Protection Agency (EPA) institutes more stringent energy requirements for commercial buildings across the nation, owners can avert fines and penalties by making energy-efficient upgrades now versus later.

Call us at (314) 664-3536, so we can design, build or retrofit a mechanical system precisely engineered to keep your occupants cool and comfortable, while reducing your monthly energy costs in North County.

Commercial buildings have the capacity to drive down energy costs by at least 15% with a building automated control system. These software programs sync with mobile devices, allowing commercial property managers to control, each room’s temperature, lighting, ventilation and cooling according to occupancy.
