The Ultimate Fall/Winter HVAC Maintenance Checklist

As the winter season approaches, most homeowners are focused on getting their houses ready for the cooler months ahead. While every system in your home needs attention in the lead-up to the cold weather months, it’s crucial that you perform maintenance on your HVAC system.

Fall and winter can be a very stressful time of year for your HVAC system, and if you don’t perform the right maintenance tasks, then you may have to deal with expensive repairs and outages that affect the comfort of your home and family. Follow this ultimate HVAC maintenance checklist and you will be able to help keep your system running throughout the toughest months of the year.


Maintaining air flow is one of the most important things that you can to do to ensure the continued functioning of your HVAC system, and the best way to promote proper airflow is by frequently replacing your air filters.

When your air filters become dirty, it can reduce the efficiency of your HVAC system and can strain its parts, sometimes causing extensive and expensive damage. To make sure that your system is as efficient as possible, you should check your air filter every 30 to 90 days, and replace filters that have accumulated large amounts of dirt and debris.


Another important task that should be on your HVAC maintenance checklist should be to remove dirt and debris from your system. If your HVAC system features aground level outdoor unit, you will need to examine the unit every week and remove any debris that has the potential to influence its functionality, including dirt, pollen, and sticks.

Anything that may block airflow in your system should be removed. Use gloves, and if necessary, a hose, to clean your outdoor unit. For your own safety, you should make sure your unit is shut down before you start cleaning.


When you’re getting your HVAC system ready for the cold weather season, it’s also important that you frequently clean the vents (sometimes called registers) in your home. Dirt and pollen can quickly build up on vents, reducing the airflow in your home and also impacting your air quality.

If you want your HVAC system to work the way that you need throughout the year, your vents should be cleaned at least once a week as part of your normal cleaning routine, if not more. Fortunately, cleaning your vents is very easy, and requires only a damp rag. Cleaning your registers will reduce stress on your system so that your HVAC can keep your home at your desired temperature.


If you follow these simple tasks on your HVAC maintenance checklist, you should be able to keep your system running throughout the year. However, if you want to make sure your HVAC maintenance is done correctly, or if you’re experiencing a problem with your system, you should be sure to get help from the heating and cooling professionals at Legacy Air.
