Service Matters: Building Operations Recommendations During COVID-19 Pandemic

Friday, April 10, 2020

Speer Mechanical is committed to continuing to provide the best service for our customers during the COVID-19 pandemic. COVID-19 is a highly infectious respiratory disease which includes symptoms such as cough, fever, tiredness, and in severe cases, difficulty breathing. According to the WHO (World Health Organization), “COVID-19 primarily spreads through droplets or particles of saliva or discharge from the nose when an infected person coughs or sneezes…” Following the guidelines set by the CDC (Center for Disease Control and Prevention) and WHO including following stay at home orders, social distancing, disinfecting frequently touched surfaces, installing additional hand sanitation dispensers, and supervising or closing food preparation areas, coffee stations, and drinking fountains will help to flatten the curve and reduce the number of infections. Read More...

Service Matters: Speer Mechanical Response to Coronavirus

Thursday, March 12, 2020

I am sure many of you have been following the news regarding the Coronavirus and its spread to the US. In response to this, please read the attached Speer Industries office policy on Coronavirus. Also attached is information from the CDC. What impact the Coronavirus may have on our field operations is under discussion. However, no employee should report to work if they are exhibiting any symptoms that are similar to those of the Coronavirus or believe they have been exposed to the Coronavirus. Read More...

Solving the Conundrum of Open Protocols in Building Automation Control Systems

Thursday, December 21, 2017

Even with widely available product flexibility for today’s building automation control systems, building owners and facility directors can struggle with the complexity in communications between automation control systems. Effective building automation requires complex communication between all kinds of different building systems—lights, mechanical equipment, security systems—the list seemingly goes on and on.

Historically, proprietary control systems limited product flexibility, and subjected building owners to potentially increased costs by limiting competition. While reliance on strictly proprietary systems is declining (mainly driven by web based solutions), truly open systems can still be challenging.

What Exactly Are Protocols in Building Automation Control Systems?

Protocols are simply communication and data sharing rules and standards related to building automation equipment that are developed and maintained by independent organizations.

Service Matters: 10 Tips for Extending Compressor Life

Tuesday, August 01, 2017

Compressor failures are one of the most costly repairs to an air conditioning system. It is rare for the compressor to fail simply due to the compressor itself. Usually a compressor failure is symptomatic of another problem with the AC system (more on this in a later Service Matters). Read More...

A Fresh Look at VFDs

Thursday, June 22, 2017

A variable frequency drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the motor. VFDs have been in use since the 1980s, and today, the combination of energy awareness, energy regulations, and new VFD technologies are driving an increasing demand for these energy-saving products.

The concept of a VFD is fairly straightforward. Frequency (hertz) is directly related to a motor’s speed (RPMs). The faster the frequency is, the faster the RPMs go. If an application does not require an electric motor to run at full speed, a VFD can be used to ramp down the frequency and voltage to meet the requirements of the electric motor’s load. As the application’s motor speed requirements change, the VFD can turn the motor speed up or down to meet the speed requirement.

Service Matters: Mechanical System Maintenance and Indoor Air Quality Team Up

Friday, April 28, 2017

Some things just naturally go together. Consider:

• Peanut butter and jelly
• The 4th of July and fireworks
• Fred & Ginger
• A cold beer at the ballpark

Good indoor air quality (IAQ) and effective mechanical system maintenance are two more. Good indoor air quality is complex, and your mechanical system plays a critical role in its two most important components, adequate ventilation and moisture control. Adequate ventilation includes both the proper utilization of outside air and the assurance of proper airflow into occupied spaces. Read More...

Indoor Air Quality and Energy Conservation—Working Together For Healthier, More Efficient Buildings

Tuesday, March 28, 2017

Sometimes it seems that many energy conservation measures related to HVAC systems are incompatible with providing good indoor air quality (IAQ). However, with a little forethought and proper maintenance, significant energy savings from HVAC-system use can be achieved while still providing good IAQ. Follow these simple guidelines and see how you can improve air quality and maximize energy conservation for your building.

At a base level, take care to provide adequate ventilation and always meet the standards of ASHRAE 62.1-2016.

A good starting point is to understand the basic HVAC energy conservation or retrofit measures that are compatible with IAQ, including:

  • Tightening the building shell, as long as adequate ventilation is provided
  • Reducing internal loads with lighting or office equipment upgrades (if these measures reduce air flow requirements, be sure to consider the increased outdoor air necessary to maintain ventilation requirements)
  • Upgrading fans, motors and drives
  • Upgrading chillers and boilers
  • Installing energy recovery ventilation systems (ERV)
  • Equipment downsizing

Service Matters: Combustion Analysis—An Essential Part of Boiler Maintenance

Friday, February 03, 2017

A boiler is a complex piece of equipment. While some diagnostics can be done by observation, a detailed understanding of a boiler’s operation can be diagnosed through a combustion analysis, similar to your family doctor ordering “a complete blood-workup” with your annual physical. Read More...
