We applaud any leader's commitment to an improved work environment for their employees, and recognize the huge investment that this commitment can take. Since the heating, cooling and air quality of a building can play such a major factor in a happy and productive environment, we wanted to provide you with some simple mid-year maintenance tips to make sure your commercial and industrial HVAC systems are in check.  Below you can find some recommendations from Ryan King and Mike Bess, members of the Cambridge customer service team.

  1. Check the air filters.  Clean these filters if necessary because dirty filters will reduce CFM and could damage the discharge air sensor. 
  2. Grease the bearings.  The grease should be evenly distributed around the race; however, do not use the standard bearing grease in the Baldor motor.  This motor takes special grease that can be referred to in the technical manual.
  3. Check the belt tension and inspect for wear.  If the belt is too tight, it can  prematurely wear out the bearings and the belt.  If the belt is too loose it can slip or squeal.  
  4. Cycle the unit on and off in all modes of operation.  This ensures things are working per specifications.
  5. Check the discharge temperature.  Use a wired thermistor at the mixing box and calibrate the system if necessary.
  6. Inspect the control panels.  Look for any loose or frayed wire connections and make sure all connections are tight.  
  7. Check and clean the evaporator and condenser coils.  Dirty coils will drastically reduce cooling equipment efficiency and strain the compressor. 
  8. Perform a gas valve leak test.  This verifies the integrity of the valves.
  9. Verify that the manifold differential gas pressure matches the nameplate.  It is extremely important that this is set up properly.  If the manifold pressure is incorrect, the heater temp rises and its efficiency will be affected.  
  10. Inspect direct evaporative media (CELdek).  Ensure that there is proper water flow across the media. 
  11. Check the calibration of digital thermostats.  Press the up arrow and hold it; the display should show 0F.  If not, the calibration may have been adjusted to show a warmer or cooler temperature than desired.

We know you’re busy, and sometimes the easiest way to get direction on a service question or instructions on how to install can best be obtained by a quick “How-To” video. For that reason, we’ve compiled some service videos that you can view at your convenience that may help you with a Start Up or troubleshoot a problem you may be experiencing.

As always, our service team is happy to assist you with any questions you may have. Please call us at (888) 976-4451or email: service_dept@cambridge-eng.com

 

“Comfort” is an interesting word that we use a lot at Cambridge.  Since we are an HVAC company, it is usually in context with making sure the people in your industrial facility are breathing fresh, tempered air, or making sure that your employees in high-bay buildings aren’t freezing in the dead of winter. There’s also “comfort” in the realm of making sure your employees know that you’ve got their backs and have a genuine interest in their personal health and professional growth.  (see blogs on Dale Carnegie Leadership Training and Stretching Your Way to Workplace Safety to generate ideas of how to boost comfort both personally and professionally).
 

Still, most companies overlook the importance of physical employee comfort, and are losing real talent and real opportunity to grow with those employees when they leave to pursue a workplace that can meet and exceed their basic requirements of a healthy working environment.
 

Not convinced? Here are four reasons that we think will back us up.
 

Safety protocol alone is reason enough.

According to OSHA – your workers have the right to working conditions that do not pose a risk of serious harm.  The OSHA website starts with a dire warning: “The quality of indoor air inside … workplaces is important not only for workers' comfort but also for their health. Poor indoor air quality (IAQ) has been tied to symptoms like headaches, fatigue, trouble concentrating, and irritation of the eyes, nose, throat and lungs.” This safety protocol is actually far, far above a “comfort” suggestion – and could be downright dangerous if ignored.
 

And even though we could stop after the safety reason, here are three more reasons to consider:
 

You can’t exist without them.

Unless you are a completely automated company or self-employed, you depend on at least one employee to get your product or service sold, produced, billed, you name it. Employees know that they have employment options – especially in trade professions, where there is a serious labor shortage. Don’t doubt that even if an employee feels fairly compensated, they might still leave because of continuing discomfort in their workspace.
 


 

Continuous improvement falls apart when it’s not the priority.

Imagine a humid July day in a distribution facility, when you can’t imagine doing anything but cooling off. We spend a portion of every day identifying opportunities for lean improvement in our processes and workspaces, but even we know that these can fall by the wayside when it is just too hot or too cold.
 

They are your brand ambassadors.

Client services to your customer.

Seasoned laborers to new hires.

Any employee to the world on social media.

Your employees can and should be your biggest advocates, because they are treated right (and physical comfort plays a big role) and believe in your product or service. The opposite of these two things can destroy every sales opportunity on your books this year.

There are so many ways to make your team feel comfortable – and they deserve it, so make it a priority to figure out the right investment to provide them a workspace in which they can reach their full potential.
