Yes, you should have a service and repair plan that outlines when and how you will maintain the HVAC system in your facility. This plan should include a schedule for regular maintenance in addition to which tasks will be completed. You should also include a set of steps to follow when an issue arises during maintenance or otherwise.
Some of the advantages of a service and repair plan are:
They keep you and your facility teams organized: Facility managers already have a lot to keep track of. Having a plan in place removes the burden of having to create new procedures on the fly to address emergencies.
You control interruption of HVAC during repairs: Several types of maintenance require all or part of the HVAC system to be shut off. Controlling when these outages occurs will allow smooth operation of your facility, whether it contains product, people, or both.
Service and repair plans lower operating costs: By regularly servicing your HVAC system, you will enjoy lower operating costs. A well maintained HVAC system will have improved energy efficiency, lower need for expensive emergency repairs, and an extended life span which lowers its overall cost per year.
