Preventative maintenance for the chiller is mandatory in Jefferson County, MO. As commercial building managers brace for another sultry summer, the chiller tops the list of priorities. Because commercial spaces have to abide by specific energy conservation standards, indoor air quality guidelines as well as the manufacturer’s care instructions; chillers have to undergo annual preventative maintenance.

Commercial buildings designed with a chiller in Jefferson County have to meet state and federal safety and energy statutes. The regulation mandates a schedule of when specific parts of the chiller submit to specific check-ups to remain up to code.

If you’re considering bids for preventative maintenance for your commercial building’s chiller, Hoffmann Brother’s Mechanical contractors compiled an abbreviated checklist of items that should be completed during the chiller tune-up.

For safety purposes, a mechanical engineer should conduct a comprehensive evaluation of the chiller’s motor to ensure that all the connections are appropriately linked from the motor to the starter.

In observance of Missouri’s Clean Water Act, the chiller’s backflow device must comply with an annual preventative maintenance schedule.

To improve energy consumption and safety, a mechanical technician will lubricate and adjust parts of the chiller. The chiller’s insulation is another area of the inspection.

At least once a year, the condenser tubes on certain chiller models have to be cleaned with a brush or an acid clean (depending on the model).

Mechanical Contractor Talks Ductless Air Conditioning

With the U.S. Environmental Protection Agency (EPA) and the Department of Energy (DOE) instituting new energy regulations, a variable refrigerant flow (VRF) ductless air conditioning system is an energy-efficient application for precise, indoor comfort control.

So, what exactly is a VRF?

Variable refrigerant flow systems generate spot heating and cooling for the individual rooms of a large commercial building, -- via a split zoning system. As a specific space needs cool or heat conditioned air, the VRF moves refrigerant to its zone. This ensures precision controlled comfort.

What types of commercial buildings in St. Louis City are suitable for a variable refrigerant volume (VRV)?

Ideal for individual rooms requiring customized HVAC systems, VRVs accommodate various types of commercial buildings in St. Louis City.

Variable refrigerant volume (VRV) systems suit hospitals, schools, hotels, office buildings and other commercial facilities.

 

How does a variable refrigerant flow system work?

Synonymous with a VRF, the VRV systems are ductless heating and air conditioning systems that enable one outdoor condensing unit to feed multiple indoor fan coil units.

What are the underlying benefits of a variable refrigerant flow system?

Scalability and energy conservation are the underlying advantages of a VRV. The ability to heat and cool rooms and spaces, as needed ensures energy conservation.

For commercial buildings in St. Louis City, VRFs allow commercial managers to control rooms independently or according to its single or multiple zoned areas. This flexibility ensures highly effective and energy conservative heating and cooling all year round.

“Not to mention, VRFs offer commercial buildings in St. Louis City the freedom to install a new heating, cooling and ventilation systems without being constrained by its ductwork, ” shares a mechanical engineer of St. Louis City’s preferred mechanical contractor, Hoffmann Brothers.

Since a VRV does not require ductwork, these mechanical systems are far more energy efficient than a conventional HVAC system for a commercial building. Because ductwork has a tendency to leak air, and VRVs capture air, moving it indoors, there’s an innate energy savings.

Is a VRV or VRF right for your St. Louis City building’s mechanical HVAC system? Schedule an energy consultation at 314-664-3536.

What’s the best mechanical system to balance energy conservation with indoor air quality? Jefferson County Mechanical Contractor, Hoffmann Brothers reviews three mechanical systems, known to promote energy conservation. Variable Frequency Drives, high efficiency roof top units with economizers, building automation control (BAC) systems represent three mechanical HVAC systems designed to accommodate conservation.

From industry-to-industry, there's no one-sized fits all mechanical HVAC system. In Jefferson County, commercial properties possess distinct requirements to heat, cool and manage daily operations.

Humidity is generally an ongoing weather condition in Jefferson County from May through September. Commercial building managers often overcompensate by lowering the temperature to combat mugginess indoors. The only problem is that this raises monthly energy consumption during the summer. So, the question becomes how to curtail humidity without expending more energy?

“Sometimes a variable frequency drive (VFD) is the best solution to manage humidity and reduce energy loads.” shares a mechanical engineer at Hoffmann Brothers.

For Joyce Meyer Ministries, the mechanical contractor designed and built a VFD for each blower motor of a Trane roof top packaged unit. The variable frequency drive proved advantageous. Hoffmann Brothers’ VFD retrofit eliminated humidity by almost 30 percent, rendering an impressive energy savings.

In situations, where indoor air quality (IAQ) does not meet the U.S. Occupational Safety and Health Administration’s standards, a new high efficiency roof top unit, designed with an economizer, can resolve IAQ problems.

Building occupancy varies throughout the day at certain commercial properties office buildings in Jefferson County. Some commercial property managers in Jefferson County utilize building automation control (BAC) systems to monitor and modify climate, lighting, humidity and other mechanical systems, remotely. Building automation control (BAC) systems alleviate energy waste, customizing temperature according to occupancy. Building automation systems serve as a mobile dashboard, enabling building engineers to manage energy according to the commercial property occupancy level, and other mechanical systems.

Mechanical Contractor Prescribes Energy Conservation Tips

Is your commercial building ready for the warmer months facing St. Charles County? Is your mechanical system meeting local energy codes and bylaws? Would you like to curtail this summer's energy costs?

Mechanical contractor, Hoffmann Brothers, an energy conservation partner of St. Charles County buildings, provides several tactics to defeating high-energy costs and meeting federal and state guidelines.

Start with an energy audit. These assessments reveal energy conservation strengths and weaknesses. Hoffmann Brother conducts a comprehensive energy audit.

After the energy audit, be sure to pose the following questions:

Has the Missouri Department of Natural Resources, US Environmental Protection Agency or the U.S. Occupational Safety and Health Administration (OSHA) instituted new guidelines that affect your buildings commercial space in St. Charles County? Is your building in compliance?

Which mechanical HVAC systems are suitable for curtailing energy loads in your building? Remember to confirm that the mechanical system is OSHA and the EPA compliant.

If the mechanical contractor recommends a replacement or fix, ask for a calculation of how much the new HVAC will enhance energy conservation. This energy assessment should identify how much your building stands to save over its shelf life.

Does your commercial building qualify for any current tax rebates or incentives? The US. Departments of Energy and the Internal Revenue Service are currently offering an energy tax rebate geothermal systems to qualifying commercial spaces. Hoffmann Brothers, a St. Charles County mechanical contractor highlights the major points of the geothermal energy credit here.

And in the event that your system meets all federal, state and local regulation standards, next, schedule preventative maintenance.

Preventative maintenance assures two critical functions for commercial buildings in St. Charles County. Indoor air quality, energy conservation, and overall mechanical system longevity represent three reasons to uphold a regular preventative maintenance schedule.
