Now that temperatures are starting to climb quickly, schools may soon be cranking the air conditioning. While this anticipated blast of cool air may seem to work like magic, a great deal of preventative maintenance goes into ensuring this function operates properly. In light of this seasonal switch, maintenance managers and their teams should make getting their schools' HVAC systems into gear a top priority so they can transition from hot to cold without a hitch.
The equipment associated with your HVAC system needs to be in tip-top shape, or else it could not only fail to work, but also cause damage. Conducting seasonal inspections of this system's components should be an integral part of your preventive maintenance practices. As you and your staff examine these pieces of equipment, there are certain precautions that you will want to take so you can ensure optimal air conditioning.
Keep it clean
A large part of keeping your HVAC in prime condition is cleaning, as it guarantees that both air and water can flow freely throughout the proper portions of this system. The first thing you will want to do when prepping your equipment for the warmer months of the year is to replace your filter on a monthly basis. Lint and dust particles tend to fill these parts, preventing air from passing which defeats the whole purpose of these systems. If your school's air conditioning uses a HEPA filter, which lasts about six months, you should simply vacuum it so that it's clean and ready for action.
Additionally, you will want to take a look at your system's drain, which allows water runoff generated from condensation to make its way out of your school buildings. Examine the hole at the bottom of your AC cabinet and right under the evaporation fan to see if there is any buildup. If there is, be certain to clean it using a wire. This will prevent the drainage component from becoming clogged, which would cause water to back up into your school, create damage and impact the humidity in your buildings.
Tie up loose ends
Energy Star recommended that you also lubricate dynamic components in your HVAC systems. With everything well-oiled, parts can move with less friction, boosting energy efficiency and reducing wear and tear on your AC motors. In that same vein, cleaning your evaporator and condenser coils is crucial to avoid overworking your system. If these parts are dirty, it will take more out of your machinery to cool your school.
As a finishing touch, the source advised that you evaluate your system's refrigerant levels. Unless your AC unit has the right amount of this agent, your HVAC won't be working to the best of its ability.
