As the days become cooler, you need to make sure you have a reliable HVAC system for your commercial property. This means you have to look into HVAC maintenance for the season. In today’s post, local heating and air conditioning service provider Mechanical Technologies shares the things you should include on your commercial HVAC checklist.
Replace air filters — Air filters trap impurities in the air and get clogged over time with dust and other indoor air pollutants. Most HVAC systems need air filter cleaning or replacement every one to three months. Regularly check your HVAC systems at least once a month and replace them when they’re clogged. In addition to maintaining indoor air quality, clean air filters also help maintain HVAC system efficiency.
Clear drain lines and pans — Moisture absorbed by your HVAC system is taken away through drain lines and collected in condensate pans. Inspect the drain lines and make sure they’re not clogged. If normal cleaning procedures don’t clear out clogs, call for AC repair. Also, make it a point to regularly empty the condensate pans.
Check electrical connections — Keep an eye on electrical connections that lead to your HVAC system, particularly the ones that go to the outdoor unit. Outdoor conditions can cause faster deterioration of the equipment, which means wires exposed to these conditions require frequent inspection.
Check fan motor operation — Commercial HVAC systems typically have noisier units compared to their residential counterparts, but you should still be able to tell the difference between “good” and “bad” HVAC sounds. Moving parts such as the fan motor may need to be adjusted or lubricated if they’re making unusual noises. If you have to apply lubrication to motors, bearings and other moving parts, use only the type recommended by the manufacturer. Substituting a different type of lubricant could result in damage.
Test the thermostats — Go around the building and test the thermostats by manually adjusting the temperature by a few degrees, then setting it back once you feel the change in temperature after a few minutes. If the thermostat doesn’t respond, follow the troubleshooting steps as prescribed in its user guide. Some of the steps may require performing a factory reset and replacing the batteries.
