HVAC Maintenance Checklist for Fall and Winter

As winter nears, many homeowners begin checking their homes and making sure that they are ready for the cold months. Among the different systems in your home, the HVAC system is the one that you need to prioritize and do proper maintenance on. 

Fall and winter are the two seasons that are harshest on your HVAC system, and if you don’t stay on top of its maintenance, you’re likely to deal with costly repair costs. You might also subject your family to an uncomfortable situation when your system stops working right when it’s needed the most. 

To make sure that your system works properly, here is an HVAC service checklist for thorough maintenance:

Begin with the Air Filters

Ensuring that there’s proper airflow is among the most crucial things that you need to do. The best way to do that is by replacing the air filters on a regular basis. Dirty air filters reduce the efficiency of the HVAC system and can even affect the performance of its parts and lead to damages that can be expensive to repair. It is highly recommended that you check the air filter every month or at least once every three months. If there’s an accumulation of dirt and debris, it’s better to replace the filters. 

Remove as Much Dirt and Debris as You Can

Another thing that needs to be included in your list is the removal of dirt and debris from the system. This should be done at least once a week if your HVAC system has an outdoor unit. All debris, including twigs, pollen, and dirt, should be removed as these can affect the functionality of the system. In fact, anything that could potentially block the airflow should be removed. It may be necessary to hose down the unit and to use gloves. In any case, make sure the unit is shut down before cleaning. 

Clean the Vents

When preparing the HVAC system for the upcoming cold season, you should not forget about the vents because they are prone to debris and dirt buildup. In fact, it should be a part of your regular cleaning routine. The good news is it’s not that hard to clean the vents. All you need is a slightly damp rag, and you’re set. By cleaning the vents, you’re reducing stress on your HVAC system so that it can work properly and keep your home at a comfortable temperature all year round. 

Call a Professional

When you follow the tips discussed above, it’s unlikely that you’ll experience any problems. That said, it’s still recommended that you get the help of a professional twice a year just to ensure that your HVAC maintenance is performed correctly and to determine if there’s any potential problem. That way, if there is anything that requires a repair, it will be done immediately, and the situation won’t escalate.


HVAC maintenance is necessary to ensure that the functionality of the system is kept at its highest. This is the only way you can be sure that your trusty system will work as it should, especially during winter when your family needs sufficient heating to be comfortable in your house. Getting professional heating, ventilation, and air conditioning service will also prolong the lifespan of your system and help you prevent costly repair and replacements.
