When in-house HVAC maintenance jobs are lost, the workload doesn’t usually change, it just falls on fewer shoulders – and despite creative measures to manage the work load, all too often maintenance is reduced or deferred because recommend maintenance intervals simply cannot be properly met. This situation usually means that HVAC maintenance engineers must find creative ways to manage the workload and/ or invest in preventative maintenance technologies that enable a smaller workforce to manage what a larger work force once managed. Use of cottonwood filter screens is a good example of an effective way of reducing the maintenance time and effort to a fraction of that required using traditional power washers and cleaning chemicals because they stop debris on the outside of the equipment where it is easy to clean vs. having to manage the debris after it has entered and fouled the system.
Please comment on the following questions:
- When faced with lean staffing, what creative steps do you (or if a distributor, your customer) take to keep up with the demands of HVAC maintenance?
- How do you (or your customer) prioritize what equipment gets worked on?
- What impact has reducing or deferring maintenance had on mechanical equipment efficiency, repair costs and energy usage?
- If the equipment across the operation supports production processes, what impact has reduced or deferred maintenance had on production quality and efficiency?
- If you (or your customer) already use cottonwood filter screens, how has it changed the dynamics of the maintenance process?







..Air conditioning and heating maintenance is largely a matter of economics…..If you manage commercial buildings you know that there are two approaches to HVAC maintenance. The other approach is scheduled preventive maintenance with repairs as needed…..While the scheduled approach is intuitively the way to go there are other factors not so readily apparent that reinforce the validity and economy of this approach…..Deferred maintenance break and fix is costly in the following ways… .Increased energy consumption .. .Repairs are usually more costly because of a cascading effect in the system where a small problem tends to cascade to other system components.. .Occupant comfort and related productivity .. ….A maintenance program is relatively low in cost and usually involves four visits per year to perform inspections and maintenance.
