HVAC Maintenance Checklist
- Change filters regularly. Swap them out every 30 to 90 days.
- Clean air vents and registers. Use a brush to clear dust and dirt at the top of the registers and the bottom of vents or use a vacuum cleaner.
- Keep outdoor units clear of debris. Make sure the area around your HVAC unit is free of overgrown plantings, leaves, and dirt.
- Seal drafts. Weather strip doors and caulk around windows to keep your HVAC from overworking.
- Examine exposed ductwork. Seal any holes or leaks with duct sealant or metal-backed tape.
- Monitor your thermostat. Consider a programmable thermostat to increase your system’s efficiency and avoid overrunning it.
- Check the flame. Natural gas furnaces should have a crisp, blue flame; if not, call an HVAC tech immediately.
- Clean the drain line. Flushing it out regularly will help avoid clogs.
- Check carbon monoxide detectors. Test monitors monthly. Replace batteries annually.
- Schedule a professional checkup. Have units inspected at least yearly.
