Get Set For Winter With This HVAC Checklist

Weather extremes are putting more pressure on homeowners’ heating, ventilation, and air conditioning systems in keeping homes cool during the summer and warm in the winter. That's one reason it's more important than ever to keep up your HVAC maintenance. But that's not always top of mind for homeowners.

The HVAC often runs in the background, which means you likely don’t give it much thought — until it breaks down, that is. And that can happen at the worst times. Forty-two percent of homeowners say they’ve experienced HVAC system issues during heat waves, according to a new survey. A failing HVAC system during a scorching summer can lead to discomfort, costly utility repairs, and even health risks for more vulnerable populations.

But many costly HVAC disasters can likely be prevented. For example, fewer than half of homeowners, 47%, say they’ve had HVAC servicing within the last year. Yet, experts advise annual HVAC servicing to avoid expensive repairs. Even fewer homeowners, 32%, say they’ve done basic cleaning and HVAC maintenance to help prevent heat-related home damage, according to a recent survey.

HVAC Maintenance Checklist

To be fair, many homeowners may not be sure what to do. Refer to this checklist regularly to make sure you’re doing 10 activities that will keep your HVAC humming.

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.
