When you invest in a valuable asset, it only makes sense to consider how you’re going to take care of it to make sure it stays in good shape and works well for as long as possible. Whether it’s your car, your home, or your latest electronic gadget, you’re understandably interested in keeping it looking and functioning properly.
It’s not surprising, then, that the commercial HVAC system in your building also needs routine maintenance to ensure optimal performance year after year. Beyond maintaining performance, routine planned maintenance also assures the system is running at top efficiency, and that any worn out components can be identified before they completely fail. In all these ways, preventive maintenance saves commercial building owners money and helps reduce or eliminate the chance of costly emergency outages.
Below you’ll find a checklist outlining the top preventive maintenance services your commercial HVAC system needs throughout the year:
Autumn
The goal of fall maintenance service is to ensure all components of the building’s heating system are cleaned and functioning properly prior to being taxed by the upcoming heating season.
Some actions that will likely be required include:
- A thorough visual inspection of all heating components to verify they’re capable of performing efficiently and effectively for the coming heating season, along with replacement of any worn parts
- Diagnostic testing on any electrical controls and components to ensure the same
- A thorough cleaning of both outside and inside units to remove debris, dust buildup, and any other issues that could hinder efficient performance
- Air filter replacements
- Supply register adjustments
- Thermostat calibrations
Winter
Winter maintenance inspection and services are designed to confirm that the components inspected in the fall are holding up as expected and to ensure all heating parts are performing efficiently at the peak of the heating season.
Some items to keep in mind during this period include:
- Checking for potential energy leaks — such as poorly insulated or sealed doors and windows — that could be affecting overall heating performance and efficiency
- Monitoring that vents and ductwork are remaining clean and free of debris
- Adjusting thermostats to appropriately compensate as outside temperatures fluctuate
Spring
In the spring, long before the peak of the cooling season, a thorough inspection and evaluation of all cooling components should be performed to ensure the cooling system is up to the task of handling the hottest days of the coming summer.
After the long, hard heating season, many of the shared system components — such as vents, ductwork, fans, and electronics — should be inspected and cleaned. In addition, components specific to the cooling system should get special attention, such as:
- Ensure the condenser unit and evaporator coils are clean, free of debris, and straighten any bent coils
- Check drain lines for any blockages or leaks, clean or replace as needed
- Check the refrigerant level and, if low, locate and repair any leaks before refilling
Summer
During the peak of the cooling season, a less intensive inspection and series of evaluations can help ensure that the components tested the previous quarter are holding up as expected and that the system’s energy efficiency settings are still appropriate. If further optimization is needed based on current usage, technicians can identify these issues as part of the evaluation.
