Back to basics: Implementing a preventative HVAC maintenance program saves on costly repairs

We in the HVAC industry pride ourselves on staying on top of all the latest technology–solar, geo-thermal, high-efficiency RTUs and chillers, VFDs, web-based controls, on and on. All these technologies are exciting to learn about and more exciting to apply. Some of them even fit into the “wow” category! 

These technologies come with different prices and often with at-tractive rebates and incentives from your friendly utility. And, without a doubt, they all have their place and are worth studying and seeing if they have a fit on your project or in your facility. 

Most of these technologies are only considered if their payback or return on investment (ROI) is rea-sonable. What is reasonable? Most owners/managers want, or expect, a ROI of three years or less. Maybe an owner occupied property will accept a five year or less ROI, but that is not often. I think the three years or less was born in the time when one could get 10% to 12% on their money in an investment. But, that is for another article.

First thing is first: When considering a major equipment upgrade - plan, plan, plan!

Here is a typical scenario. Your energy and repair costs are high, you are frustrated by frequent breakdowns, you are plagued by comfort complaints from tenants or employees or maybe the equipment is past its useful life, maybe all of the above.  Somehow, you have con-cluded that you need to replace your HVAC equipment.  Even worse, you have waited until the equipment has failed.  Seems simple enough right?  You just get the size (capacity) of the equipment, call in a contractor and get some quotes on replacement, pick the lowest price and you are good to go.  Not really!  If you or your contractor is approaching your project this way, you are doing yourself an injustice.  Here’s why.

Building systems operation: How to tell if your equipment and systems are operating properly

In my last article I wrote about preventative maintenance and the benefits of it from a comfort and building performance perspective. Now we can look at how your equipment is operating, or more accurately, how you are operating your equipment. So, how do you know your equipment and systems are operating properly, and what is properly? Properly is a relative term, relative to the application. If your system was designed and installed for a specific use, your use, you have an easier task. Often we deal with equipment that was installed for a different use or maybe a different tenant. Maybe the previous application had a greater load, maybe less. Maybe there have been previous energy saving measures put in place. Those measures could include new lighting, better performing roof and windows, more efficient office equipment and finally greater or lesser occupancy.
