It may seem a little odd to begin a blog post titled “Preparing for the Heating Season” by talking about air conditioning. Yet commercial buildings place constant demands on the systems that run them, and air conditioning is no exception. Equally notable, you can learn a lot by evaluating the performance and condition of your air conditioning unit or units at the conclusion of the cooling season – and then use that knowledge to make smart decisions moving forward.

  • Happy tenants don’t grow on trees;
  • Preventive maintenance for a commercial heating and cooling (a.k.a., HVAC) unit or system can really help facility managers keep #s 1 and 2, well, manageable.

If you’ve kept up with our commercial heating and cooling (a.k.a., HVAC) blog posts so far, then you should have a good appreciation for the ways that Preventive Maintenance (PM) can help you reduce HVAC repair costs and increase unit lifespan. You’ll also have a better sense of what a baseline PM program entails. We even provided a more thorough checklist of specific PM components that can help to form the foundation of a solid PM plan.
