As winter comes, most homeowners are focused on preparing their homes for the colder months ahead. While every system in your home requires attention in the run-up to the colder months, it’s critical that you maintain your HVAC system.

Fall and winter can be hard on your HVAC system, and if you don’t do the right maintenance, you might have to deal with expensive repairs and breakdowns that make your home and family less comfortable. If you follow this ultimate HVAC maintenance checklist, you will be able to keep your system working even during the coldest months of the year.

Begin with your air filters.

Maintaining air flow is one of the most important things you can do to make sure your HVAC system keeps working, and the best way to do this is to change your air filters regularly.

When your air filters get clogged, it can slow down your HVAC system and put stress on its parts, which can cause serious and expensive damage. To keep your system running as efficiently as possible, check your air filter every 30 to 90 days and replace filters that have gathered a lot of dirt and debris.


The removal of dirt and debris from your system should be another important task on your HVAC maintenance list. If your HVAC system has a ground-level outside unit, you must inspect it once a week and remove any material that could interfere with its operation, such as dirt, pollen, and sticks.

Remove anything that could obstruct your system’s airflow. To clean your exterior unit, use gloves and, if necessary, a hose. Before you begin cleaning, make sure your unit is turned off for your own protection.


When getting your HVAC system ready for cold weather, it’s also important to clean your home’s vents, which are also called registers. Dirt and pollen can quickly build up on vents, which cuts down on airflow and makes the air quality worse.

If you want your HVAC system to function properly throughout the year, you should clean your vents at least once a week as part of your regular cleaning regimen, if not more. Cleaning your vents is quite simple and simply requires a moist rag. Cleaning your registers will make your HVAC system less stressed, so it can keep your home at the temperature you want.
