Mechanical Contractor Reviews Energy Saving Strategies What’s depleting your building’s energy conservation--could it have to do with the commercial HVAC system? In Maryland Heights, commercial buildings often rely on the premier partner in energy conservation: Hoffmann Brothers. In this blog installment, Hoffmann Brothers mechanical contractor firm reviews several strategies to drive down energy expenditures this summer. After work hours or when the building is vacant, administer an energy audit. Have a mechanical contractor, licensed in Maryland Heights determine which appliances are absorbing unnecessary energy. Establish a monthly schedule to check on the boiler, furnace, ventilation, heat pumps and other mechanical systems. These regular maintenance check ups often identify solutions to enhance a commercial building’s HVAC-R system’s performance and efficiency. During the energy audit evaluation, a mechanical systems contractor can show you energy vulnerabilities in your building’s mechanical system. A precision tune-up optimizes a Maryland Heights building’s heating, cooling and refrigerating and other mechanical systems. Amend your operation’s staff hours to allow for improved energy conservation. Consider a building automating control system (BACS) to manage lighting, cooling and other energy-using appliances. A BAC enables your building to set goals for energy conservation. For instance, some commercial property managers employ a BAC system in Maryland Heights to curtail the energy used to light a building, by 10% to 40%. Share energy conservation goals with your building’s occupants. Ask occupants to power off printing machines, copiers, and computers and fax machines at the conclusion of the workday -- as these electronic fixtures generate heat, offsetting the energy used to cool the atmosphere. Replace outmoded office and industrial applications with ENERGY STAR certified electronics. Dirty air filters are not only bad for indoor air quality (IAQ) but energy conservation. As a result, establish an ongoing schedule to change your building’s HVAC filters. Select a preferred and trusted mechanical contractor in Maryland Heights to secure priority service appointments on heating and cooling repairs, and precision mechanical system tune-ups and special pricing. Maryland Heights’s businesses rely of Hoffmann Brothers for all of their mechanical system enhancements, retrofits and design. Give us a call at 314.664.3536.


Bid quotes represent only a facet of decision making when it comes to evaluating a mechanical contractor in St. Clair County. The criterion for assessing a mechanical engineer exceeds the upfront costs. What are the contractor’s prior project experience, credentials, employment hiring practices and other contingencies?

How to qualify a mechanical engineer in St. Clair County?

Credentials matter. Is the mechanical contractor a licensed engineer or a certified technician? Is the mechanical contractor an affiliate of any organizations? Only a licensed mechanical engineer has the proficiency to design, build or retrofit an HVAC-R system for a commercial building in St Clair County. Organizations such as the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), the American Society of Engineers authenticate a mechanical contractor’s credibility.

Experience counts. Considering that a commercial building erected in the 1970s varies distinctly from one built in 2000. The mechanical engineering specifications vary widely for medical centers, pharmaceutical manufacturers, office buildings restaurants, breweries, furniture makers and other commercial properties. As a result, analyze a mechanical engineer’s prior project list to determine if the company has the expertise to execute your building’s HVAC-R   needs.

Discerning hiring practices. What is the mechanical engineer’s firm hiring standard? Are the technicians certified? Note that a mechanical contractor’s staff is just as important as the owner’s credentials. For example, Hoffmann Brothers Mechanical contractors hire graduates who earned the highest grades from the most respected technical schools, (i.e. Rankin and Vatterott).

(St. Charles County, MO) Mechanical HVAC-R contractor recognizes June as National Safety Month with a few workplace data points, recommendations and ideas:

The National Safety Council reports that workplace injuries accounted for $200 billion in 2012. Even though occupational accidents, injuries and illnesses are often unforeseen, some actuaries estimate that there is a return on investment in safety.

Even as construction, manufacturing and trucking account for the highest workplace incidents, indoor air quality (IAQ) is commonly an overlooked health issue in the workplace.

Investigate your building’s IAQ in St. Charles County << here.

The US Occupational Safety and Health Administration (OSHA) deems indoor air quality to be a facet of providing a salubrious workplace environment. In other words, a respiratory condition due to poor indoor air quality maybe defined by OSHA as a workplace injury.

A building's heating, cooling and ventilation system influences indoor air quality.   In one case, a professor won a lawsuit after finding out that a mold infestation was the byproduct of the plaintiff’s respiratory problem.

What justifies investing in a commercial building's mechanical system in St. Charles County, MO now than later? As long as a mechanical system offsets looming regulations, future inflation costs and the prevention in future workplace injuries, then an upgrade merits the investment.

“In St. Charles County, managing mold is often an ongoing problem when building owners overlook the mechanical system,” forewarns a mechanical engineer of Hoffmann Brothers,

In St. Charles County, some commercial building owners are instituting mechanical system retrofits, and upgrades before stringent guidelines set in. Hoffmann Brothers Mechanical Contractors not only specializes in designing and building mechanical services, promoting energy conservation, but designs HVAC-R that complements good indoor air quality.

Mechanical Contractor Talks Dehumidification

Humidity happens to be a prevalent side effect of the average St. Charles County, MO summer. However, local commercial buildings have to observe specific state and federal regulations. The U.S. Occupational Safety and Health Administration (OSHA), Department of Energy (DOE) and the Environmental Protection Agency (EPA) set benchmarks on dehumidification system's capacity and energy factors (EF).


Managing moisture entails a balance between low humidity and energy conservation. The process for dehumidification is changing across many industries. In the past, an exchanger would overcool the air supply; and, then reheat the air to curtail moisture to the specified temperature.  However, this form of dehumidification wastes substantial energy use for most facilities of St. Charles County.


Data point Hoffmann Brothers Mechanical Engineers have designed and built dehumidification systems for pharmaceutical industries, hotels, restaurants, churches, and other commercial properties.


At industrial environments, where very low humidity is a requirement, there are several dehumidification technologies to apply. Ranging from gas desiccant systems to highly energy-efficient dehumidification processes, Hoffmann Brothers design units for commercial properties of St. Charles County to thwart moisture, using the least energy possible.


Managing humidity is quite critical in the hospitality industry. High humidity levels create a hotbed for mold growth and an uncomfortable environment for patrons and guests. When a dining establishment forgoes proper dehumidification in St. Charles County, it's a recipe for mold, mildew and a host of other unwanted outcomes. The same is true for hotels. In order to prevent health concerns and uphold customer satisfaction, proper dehumidification is essential from the kitchen to the dining room.


In St. Charles County, Hoffmann Brothers has improved the humidity levels for Nomax, Joyce Meyer Ministries, Super 8 Motel, and St. Charles Baptist Church--to name a few.


Schools represent another commercial indoor environment, where curtailing humidity is important. Without the proper dehumidification process, students may be exposed to airborne contaminants, viral infections and other bacteria.


Whether it's to control humidity during the production process or for other commercial buildings, Hoffmann Brother's Mechanical Engineers designs dehumidification systems to ensure a healthy and safe indoor air quality.

As the state of Missouri recognizes May as "Clean Air Month," let's evaluate your building's indoor air quality and greenhouse gas (GHG) emissions. It's no secret that the U.S. Department of Energy (DOE) has an extensive list of new regulations, slated for the next five years. For most commercial buildings in Jefferson, St. Louis and St. Charles Counties, the new energy guidelines call for several orders of business. Hoffmann Brothers, a preferred mechanical contractor, serving the Counties of Jefferson, St. Louis and St. Charles provides this checklist.


1) Schedule an energy assessment for your building to determine if the mechanical system is in compliance with the EPA's new standards. Ranging from air quality to energy efficiency, a mechanical engineer will evaluate a lengthy checklist about your building's energy consumption.


Review additional information by the Missouri Department of Natural Resources EPA laws


A mechanical engineer may recommend improvements that address both IAQ, and the US Occupational Safety and Health Administration benchmarks.


If your building's cooling system has not been checked this year, be sure to schedule its preventative maintenance.


Please visit: St Louis Mechanical Contractors to schedule maintenance for your building's cooling system in Jefferson, St. Louis and St. Charles Counties.


2) Consider energy compliant replacements. In Jefferson, St. Louis and St. Charles Counties, many commercial spaces employ controls and facility automation to monitor, manage and curb energy.


A building automaton system BAS helps building engineer control energy, as needed, when and where needed.


Replace outmoded heating, ventilation, air-conditioning and/or commercial refrigeration that may violate new energy standards. The EPA is phasing out the air-conditioning refrigerant R-22 over the next six years. Avoid major investments in mechanical systems that will soon be outlawed.


3) Prior to finalizing any mechanical HVAC system replacements, inquire about any current state or federal tax credits.


Certain commercial buildings in Jefferson, St. Louis and St. Charles Counties qualify for a geothermal system under section 48a of the Internal Revenue Service (IRS) code or a 10% tax credit. These renewable-energy sources are EPA and DOE compliant. Read more about the commercial tax credit >>


4) To ensure that your commercial building is making a sound investment, request an analysis, including price, longevity, energy conservation by the year, maintenance and etcetera.
